A complex bathroom microclimate, characterized by high humidity, sharp drops of temperature and difficult to circulation of air masses, allows for the repair of this room only moisture-resistant materials. Usually on the walls and floor put tiles. It is difficult to glue the tile for a long time and difficult, since this work requires careful surface preparation and dismantling the old decorative coating from the wall. Therefore, many homeowners are wondering if it is possible to put a tile on the tile, which has already become unusable. In this article we will talk about the pros and cons of this controversial technology. Many homeowners are experiencing panic fear before repairs in the bathroom. This position can be understood, because finishing works in this room are associated with large financial costs and a huge number of construction waste. To properly glue the tile on the wall or floor of the bathroom, you must first dismantle the old tile, which takes a lot of time and strength. Laying tiles Experienced finishing masters believe that glue a new coating in the bathroom to the old tile can be in the following cases: If you remove the old tile in the bathroom before gluing a new tile, you will have to fill the floor with a tie, and the walls are re-coated with liquid waterproofing. These factors lead to an increase in the repair duration and to an increase in the cost of work. Old tile, if it is in good condition, can be considered an excellent waterproofing layer and lay a new coating directly to it. Tile removal Note! If you glue a new ceramic tile on an old coating, the floor level will rise by several centimeters. In the bathroom, it must be 2-3 centimeters below the level of the rest of the premises.

Old cracked tile should be removed
To understand whether it is possible to use an old tile to put a new one, you need to correctly revise its condition:
Important! Experienced, finishing masters believe: if, when revising, the coating condition it turned out that more than 10-15% of the area has defects or needs to be removed, it will correctly dismantle the old finish and glue the tile on the surface cleaned to the base.
Applied tile adhesive
You can glue the tile on the old coating if the elimination of defects is required in several places. Otherwise, the strengthening of the foundation takes more time and means than dismantling the old tile and the creation of a waterproofing layer with zero.
Putting the tile on the tile without careful preparation of the base would be a big mistake. Although this technology reduces the repair time, but does not fully exclude the preparatory stage. The main strokes that can interfere with the tile glue "grab" is the glazed surface of the tile, as well as ordinary dirt.
Laying tile on the wall
To be sufficiently adhesion and adhesion, adhesion and clutch appeared between the new ceramic tiles and the old cafeter.
Removal of glaze to base
Important! After applying the primer composition, the surface will become a rough and grainy, like a sandpaper. It is necessary to glue the tile with the use of high-quality glue designed for particularly complex or durable bases, for example, for porcelain stoneware.
Before laying a new tile, the shooting of the old one seems to be designed.
In fact, this time-consuming stage is not at all necessary.
It is quite possible to lay a tile on the tile and then we will tell you how it is done.
Is it possible to lay a tile on the tile?
On an unprocessed ceramic tile, the facing is kept poorly due to low adhesion.
The latter is due to such properties of the surface:
- No pore (does not absorb glue).
To consolidate the facing on this basis, you will have to tinker with its preparation. But the process of this less time consuming than dismantling the old cladding with the subsequent export of garbage and leveling the wall, so this solution is quite justified.
The only drawback is the double cladding "Eat" a large amount of space that is unacceptable for small-sized premises.
Preparation of the surface to laying
First you need to make sure that the old tile holds firmly. If it is not so, under the weight of the new cladding, the material falls off. Enroll as follows:
- Tile inspect on the subject of chips and seeded places. When they are detected, they are marker.
- Cutting and places with a humid sound, testifying to the presence of emptiness, also marked.
- With the help of a hammer and chisel, cluttered and detached areas and laid empty cells with cement-sandy solution. If it is assumed to apply tile glue on a cement basis, then it can itself act as an aligning mixture. The maximum thickness of the layer of such glue is 30 mm, the packaging must stand on the packaging.
Next, it is necessary to give the surface of the old coating, roughness. This is achieved in several ways:
- fully removed gloss;
- make notches;
- Ground surface with special compositions.
Work on dismantling tiles are held in protective glasses: there is a risk of fragments in the eyes.
Removal of the glossy layer
Floor covering tiles, believes with a grinder armed circle for stone work or concrete. The naked main tile material is rough and porous, which is required for good adhesion. This operation is also performed in protective glasses, as it happened that the circle ruined the centrifugal forces and his fragments were injured by the Master's eyes.
For stripping, a drill armed with a grinding nozzle is suitable.
Tile processing with abrasive tools is accompanied by the formation of a large amount of dust, therefore, the respirator should be put on and cover the equipment and furniture items with a polyethylene film.
After processing with an abrasive tool, the surface of the facing is purified from dust and degrease.
Laying tiles on the floor
Creating notches on the tile
If the new facing material has a small size and thickness, and therefore it is light, the glaze can also be considered and partially - in the form of strips with a step of 2 cm. With such a notch, the clutch force will be sufficient, and labor costs and consumables (abrasive circles and nozzles) It will take much smaller than with a solid stripping. The total area of notches should be - at least 60% of the total base area.
Instead of removing the glossy layer, you can drill in the old coating a plurality of holes.
A similar method is used in the manufacture of bricks - squeezes round recesses in it.
The advantage of the method is the lack of dust.
After the holes in the tile are drilled, it is cleaned of dust and degrease.
Make a smooth surface of roughing helps the primer "Concrete contact", consisting of such components:
- acrylic (base);
The old cladding was washed, degreased, dried and a roller or brush is applied with a layer of thoroughly mixed primer.
Implementing means of protection: glasses and gloves.
After 2-4 hours, the primer dries and hardening, turning into a rough crust.
The lack of this method is the cost of buying the primer. In the absence of "concrete contact", it is replaced by quartz primer.
Furniture and technique near the work site are recommended to cover with cloth or polyethylene film: the "concrete contact" primer is difficult to flush.
New Tile Styling Technology
For laying tiles on the tile, glue with increased grip (adhesion) adhesion is used.
The latter is measured in MPa, its value is indicated on the package.
At adhesives of different stamps, this indicator varies from 0.2 to 1 MPa.
According to the power of the clutch, adhesive compositions are in the following order (from weak to strong):
The last species is expensive and applied under special conditions: for cladding floors in places with large patency, and structures subject to constant direct exposure to water. There are still polyurethane adhesives - for "warm floors" and structures that are prone to deformities and vibrations. Under normal conditions, there is enough dispersion glue. It comes only in the finished form, has a pasty consistency.
For cladding with a glass mosaic or a tiled of marble or other light stone, white glue is used. In other cases, the color does not have.
To work will need tools:
- Metal spatulas: straight and toothed;
- Rubber spatulas: for wipping seams;
- slab chores or glass cutter;
- Bubble level.
Toggle spatulas are distinguished by the height of the tooth - from 6 to 12 mm. This parameter determines the thickness of the glue layer. Since the spatula when moving the composition is kept at an angle, followed by pressure on it with tiles, its thickness as a result is 0.3-0.5% of the height of the tooth of the spatula. Accordingly, a spatula number 8 is used to apply a layer of 2.4-4 mm thick.
On an even base, the glue layer varies from 2 to 6 mm and depends on the mass of the tile: how it is larger and thicker - the greater the glue layer. For convenience, glue manufacturers indicate not the thickness of the layer, but the spatula number recommended for laying the tile of a particular size.
Stages of work on laying tiles:
- When lining the wall below, the starting rail that prevents the sliding of the facing material is strictly mounted. The rail position during installation is controlled by the level.
- Clapping walls start from a long-range corner. For the floor of unambiguous recommendations no: start from the walls, from the corner or from the center.
- On a small section of the wall or floor are applied by a straight metal spatula of a layer of glue. Large facing products are also recommended for the glue mixture with a layer of 1 mm.
- The toothed spatula is moving the surface and give the desired thickness.
- Print tiles, pressing it, and controlling the position level. Tile have so that the seams in the new and old cladding do not coincide.
- Remove with a rag of surplus glue: this is done right away until the composition hardened.
- Similarly, glue the following tile, setting between it and the previous one, plastic cross for giving the seams of equal width. The position of cladding elements is constantly monitored by the level. The optimal width of the seams is 2-3 mm. With a greater width of the seams, grout is chosen, with a smaller - the coating looks unattractive, because to fill such a fuga gaps are difficult.
If the starting rack was not installed, with the walls of the wall, the tile is not labeled than in 3-4 rows, and then interrupted for an hour waiting for glue grip. With a larger number of rows, the coating slides under its own severity.
For laying at the end of the row, the tile is cut. Procedure Next:
- measured the width of the remaining gap;
- Measure this size on the tile and put markup marker;
- Having applied to the drawn line to a flat rack, spend on it a tile car or glass cutter, pressing the tool;
- It is easy to beat the tile plafhroy about the floor - it will split along the cut line.
Having completed the walls of the wall, dismantle the starting rail and glue the cropped tile on its place.
After drying, the adhesive is embarking on the seams. The base from the ceramic tile does not absorb water and the glue on it dries longer than the usual, because the seams are rapidly begin not earlier than 3-4 days after finishing works.
The filling of the seams is carried out with a rubber spatula. Such tools with different width are usually sold in a set, more often apply the widest one.
After 15-20 minutes. After the start of the work, they are returned to the first seam and erased by a rag or a wet sponge marks of grouting from tiles. By this time, the solution will dry sufficient, so as not to fall out of the seam during careless manipulations of the rag, and at the same time still does not harder so that it cannot be washed.
How to put a tile on the tile in the bathroom?
In the bathroom, the tile coating is mounted on the same technology, only the glue and grout apply moisture-resistant and with the additive antiseptic. Such compositions are also called fungicidal. Their application is due to high humidity: on the usual grout develops colonies of mold and fungus.
Claimes on a cement basis attach moisture resistance by shifting with liquid latex instead of water. Dispersion, polyurethane and epoxy glue moisture resistance inherent in the initial.
Moisture-resistant grouts are also divided into:
- cement with Latex shutters;
The second is super high, but extremely complex in installation. In everyday life, they are usually used only with expensive tiles: added to epoxy resin silver or gold powder, which gives the facing spectacular look.
Silicone and acrylic sealants do not apply as grouts: they are poorly washed off with tiles and often yellow with time. They fill the gaps between facing and plumbing devices (bathroom, washbasin, etc.).
In places hitting splashes on the prickly seams, it is advisable to apply a special sealant for the grout.
Since moisture-proof adhesive for tile coatings is expensive, prefer to limit the use of fungicidal grout. With high-quality filling of the seams of moisture under the tile will not penetrate.
When putting the tile on the tile can not
The use of an old tile coating as a base is not allowed in the following cases:
- The room has small dimensions: thick two-layer finish will steal a lot of scarce space.
- The old coating is poorly kept, as evidenced by the healing sound when attacking.
- The surface of the old cladding is uneven, with bulges and depressions.
- When finishing the floor: if it turns out to be above the threshold with a new layer of the tile coating. Especially relevant for the bathroom: here the floor must be lower than the floor in the corridor so that water does not fall out when flooding.
- Under the old cladding, pipelines are laid and access to them is not provided. Old pipes will soon require replacement, for which they will have to knock down a new tile. It is more correct to knock the old cladding, replace communication and lay a new tile on a clean base.
Also, the old floor cladding is knocked down if necessary to change the gender of the floor.
Installation of tiles on the tile saves a lot of work and time, so if the conditions allow, such a solution is quite reasonable. It is only necessary to properly prepare the basis, accurately adhering to the recommendations of specialists, and then the new facing will be solid and durable.
How to lay on the floor tile on old tile
Many people, deciding to repair in their home, make it thoroughly. They crush the old finish from the walls, the ceiling and floor to the very base, in order to get the perfect result of their efforts. However, this plan requires quite large investments, so often people try to save and put ceramic tiles on the floor on the old tile, and it is quite possible to do it, because this material is in such a technology on the previous decoration without problems.
Brief characteristic of the material
Ceramic floor tiles are a durable material that demonstrates high performance characteristics. Such coverage is steadily increased by the level of humidity, so actively applied in the bathrooms. It demonstrates high aesthetics, has a wide variation of drawings, color solutions and textures, therefore applies to the interiors of different stylistic orientation. Ceramics is practical and easy to operate, it is easy to wash and dries quickly.
Note that more the positive qualities of such a material for finishing the floor are manifested if its laying is carried out in all the requirements of the technology. If the work is performed thoughtlessly and with violation of the manufacturer's recommendations, it will last for a long time.
Advantages and disadvantages
Many inexperienced builders are asked whether it is possible to put a new tile coating on the old tile.
|Advantages of the method||Disadvantages of the method|
|The new floor should have a solid base. If the former tile layer was laid on conscience, then the new tile will fall over without problems||With a strong declaring of the old coating, cement glue under it will begin crumble. If we carry out the laying of a new tile on the floor on top of a fragile old base, then the coating will not serve and year|
|Leave the previous finish relevant when difficulties arise with its dismantling due to the risk of damageing undergoing water, sewage communications, and capitally installed plumbing equipment||Old high-rise buildings often have a significant field curvature, so the level of the Metlah tiles on the floor in the bathroom can be decently different from the horizontal. Such a defect needs to be eliminated using a screed, which means that the former finish will need to dismantle|
|Putting the tile on the old base is when it is necessary to save on its dismantling and on the purchase of materials to align floors to a new tile in the bathroom. It reduces repair time||The cluster of space is also considered a significant disadvantage of such technology, because the additional layer of the tile will inevitably increase the level of floors. Then the floors can be higher than in the corridor. And the bathroom is quite welcome because of the risk to flood the rest|
Laying a new tile on top of the old significantly saves time and strength
Put a new tile on the old tile
The dismantling of the old tile is often aggravated by dust and mud, it requires high labor costs and is accompanied by noise. For these reasons, sometimes a person tries to avoid dismantling the tiled floor and prefers to put a new tile directly on the old layer.
This technology is not new. However, to understand whether it is worth it to apply in a particular case, it is better to study the pros and cons of such a floor finishing method. If, after analyzing the parameters of the bathroom, it was decided to put a new tile on top of the old, then the sequence of work will consist of the following processes.
Removing the old tile - the process of long, tedious and heavy
Provides thorough preparation of the basis for subsequent decoration. The subsequent quality of new floors depends on the carefulness of this procedure. Be sure to explore each tile on the subject of chips, cracks, chosen. If the old tile is fragmented, completely remove the deformed things. The rest of the tile must be cleaned of dust, dirt. Microcracks are eliminated by grouting with cement mortar. If the defects on the tile are massive, then it is worth thinking over the complete dismantling of the previous finish. Only then can be transferred to the subsequent stage of work. If the tile has a glossy surface, it is better to apply on its surface of the notch or perform a lot of holes in it. This will increase the strength of the stacked finish.
Make sure the old tile keeps reliably
Damaged tiles better dismantle
Cracked grout preferably remove
It is carried out using various kinds of organic solvents. If you want to save, you can apply gasoline or acetone. They differ quite low cost, however, have an unpleasant sharp smell, and inhaling their pairs are extremely dangerous. If you work without protective equipment, it will negatively affect the well-being and human health. Therefore, more and more often the wizard is used for these purposes caustic soda. It is bred in water and the floor is thoroughly washed in the bathroom several times.
For degreasing, it is best to use caustic soda
The use of antifungal compositions is necessary to eliminate the risk of forming mold, fungus, other pathogens of microorganisms. After all, the bathroom is a room with elevated levels of humidity, and such conditions are ideal for the development of fungus. Processing between tile seams in this case requires special attention. It is here that the fungus and fat accumulates, if the old grout began to collapse. You should not neglect this procedure, then the new finish will be more durable.
There are many antifungal compositions for disinfection
The next step in the performance of work will be the use of primer compositions according to the type IVSIL Basis-Beton, or Ceursite CN94 to increase the adhesion of subsequent finishing materials. This means you need to cover each millimeter of the floor. Many inexperienced construction professionals argue that priming can be neglected if there were notches in the process of preparatory work on the old floor. However, such measures in a combination with the use of soil will further improve the adhesion of finishing materials.
At the end of the work we put out new tiles on top of the old, using a glue composition. However, it can be done only when completely dried primer. Putting the tile on top of the old tile coating, just as in the usual case. But still it is worth considering the following nuances. So, you need to pick up such a comb on the soldier so that its height is 10-15 mm and the right glue. And when performing a new starting series, it is necessary to place the tile so that the seams do not coincide with the seams on the old layer. Otherwise, satisfactory result will not work. If the room is small, ideally apply diagonal plates in it. This contributes to visual expansion of space.
In order to put a new tile on the old used glue composition
Tile glue type
Not every glue can be applied in the bathroom to the old tile, so it is necessary to consider the acquisition of this material as responsibly as possible. According to experienced specialists, the "IVSIL PROFIT" glue, developed for porcelain stoneware, has excellent operational parameters. When laying a tile on top of the old tile layer, this type of adhesive composition will be as impossible. No less positive reputation is famous and "Ceresite CM17". This is a durable and reliable means. It promotes high adhesion even with a smooth lower tiled layer, so the new floor in the room will be really durable, durable and resistant to negative environmental factors.
Apply a tile adhesive needle using a smooth spatula. The same adhesive tool should be aligned, and give him the relief is a toothed spatula. Next, you will need to put the tile according to standard technology.
Rustling the mixture is better with a toothed spatula
Sometimes putting the tile on the tile in the bathroom are economically more appropriate than to make a major overhaul, turning into the former finish to the very base. This can be done when the necessary conditions and proper technology are met.
Assessment of the state of the old coating
Put the floor tile on the old coating can be in the case when the former masonry does not have large defects. Works are performed in the following cases:
- The walls or gender are in excellent condition, the tile holds firmly, does not rush, and the grout does not fall out;
- When the dismantling of the previous coating can lead to the destruction of the walls;
- It is impossible to disassemble plumbing equipment and communications, because when dismantling it may be damaged;
- When removing the previous screed, there will be a decrease in the level of floors;
- In order not to take out the previous coating, since the dismantling work is accompanied by a large amount of dust and garbage.
You should also check the floor and wall level. If there is a big curvature, put the material on the old coating can not. First, the base is leveling, and then you can glue the facing. Change the old coating is necessary when:
- Tile coating begins to fall off from the floor and walls;
- On the tile formed small cracks and chips;
- Between the slabs arise cavities in which water falls;
- The air in the room became raw.
To estimate the status of the current coating, you need to perform the following steps:
- inspect the masonry on the presence of cracks, chips, discontinuations of the plates and other visible defects;
- Touch the surface for the presence of tenting elements;
- check the rapid material in the seams;
- With the help of a hammer, catching up the finish to determine the presence of emptiness under the tile;
- Construction level Check the location in the surfaces of the surfaces.
You can or can not put a new
Putting the tile on the old tile can be in the event that the coating is performed qualitatively and has no defects. Otherwise, the masonry may not hold out even for 1 year. If the old tile holds well on the glue, the fresh coating will begin to break and disappear. It can occur if there is a fungus or mold in the seams. The second coating will begin to flap due to the distribution of microorganisms and rejection of the adhesive layer.
If the old coating has inside the void, it is impossible to put it on it. Over time, in these places, the tile will disappear. Dismantlement should be done when the surface drop drop is more than 1 cm. Align the wall or floor with the help of glue is difficult, and with a large thickness of the solution, it may be bad and flap from the base. It is necessary to dismantle the old coating when more than 15% of the area has defects.
Selection of glue
To glue the tile on the old tile, you should choose the right glue solution. Under these conditions, simple mixtures on a cement basis are not suitable. If you plan to make repairs in the bathroom, the glue must be moisture-resistant. To qualitatively glued the tile over the old tile, the solution must quickly dry. This will prevent the location of the material.
It is necessary to choose the mixtures intended for these purposes. The optimal is the products of the Ceresit company SM17 and LVSIL PROFI. They can provide high-quality fixation of the tile coating on the old tile.
Glue new tile on old tile
To put a tile on the floor, you must perform the following steps:
- prepare the surface;
- carry out degreasing and disinfection;
- Protect the floor;
- Wire tile.
Work is simple, so they can be performed with their own hands without special skills, knowledge and tools.
First, the floor in the bathroom is closely studied for the presence of cracks, chips, chosen and other defects. From how carefully the foundation is prepared, the quality of the subsequent coating will depend. If the tile is broken, it is removed, and defects and fine cracks are eliminated by cement mortar. When the tile has a smooth glossy surface, there are serifs or shallow holes on it. This will improve adhesion with adhesive mortar. The layer of glaze can be removed with the help of a grinder and grinding circle.
Degreasing and disinfection
Before laying the tiles, degreasing and disinfection of the tiles and seams. Fats are removed using organic solvents, such as:
- caustic soda.
Since the first 3 substances negatively affect human health, experts recommend using caustic soda. It must be dissolved in water and rinse with a solution with a solution several times.
It is possible to eliminate the harmful microorganisms using special antifungal compositions. It is especially important to do in the bathroom, as the room has an increased level of humidity. This environment is perfect for the development of fungus and mold. For these purposes, chlorine-containing and oxygen-containing household chemicals are suitable.
For reliability, treat the surface and seams several times. Be sure to use personal protective equipment. The grout of the seams should be removed from the interlocking space if it is deeply amazed by microorganisms.
On the surface of the walls and gender you need to apply a layer of primer. Such primer compositions like Lvsil Basis-Beton, or Cerezite CN94. They create reinforced adhesion tiles with glue. The primer is applied with a brush in several layers over the entire surface. After complete drying of the composition, you can stick the tile.
Laying in the bathroom
To put a new tile, you will need such tools:
- set of spatulas;
- building level;
- pencil and roulette;
- Construction mixer;
First, the surface markup is marked, given the sizes of tiles and seams. It is necessary to accurately calculate the desired number of items to prevent overruns due to cutting material. To make the tile not slipped along the wall, the guide is installed at the second row height. It will be the basis for the following rows.
To comply with the vertical on the walls using a plumb of the drawing lines. On the floor, the laying starts from a long corner. It is important to take into account the fact that on the floor part of the seams make more than on the walls.
Then the glue solution is divorced and applied to the tile. The thickness of the layer depends on the curvature of the walls. The minimum allowable is a layer of 4-5 mm. Then apply glue to the surface of the tile, which you want to fix. Surplus are cleaned.
Now the tile should be pasted by giving it to the floor or wall. The construction level check the accuracy of laying and, if necessary, corrected the tile. If there are minor curvatures, increase the glue layer. The same actions are done with subsequent elements. Platologist is used as needed.
To make a very strong base, it is necessary to place the tile so that the seams of the old coating accounted for the middle of the plate. Strength depends on the method of laying tiles. The best is the diagonal placement of elements relative to the previous layer.
When the glue froze and scored the strength, perform the grout of the seams. For this, the material is bred by water and the interlocking space is filled with them. To avoid voids, it is necessary to push the rubber spatula into the base to the bottom. On the surface, transverse and longitudinal movements are performed by a spatula. After 10-15 minutes, the surface of the tile is cleaned with wet rag.
The tile is a very practical finishing material that is often used to decorate bathrooms. It has a large number of performance characteristics and has one significant disadvantage - expensive. It is not suiced to the preparation of the foundation for cladding. Therefore, the one who wants when performing repair, save a little, often interested - is it possible to put the tile on the old tile in the bathroom. You definitely cannot be answered. And all because there are not so many situations when old laying can be saved.
Indications for work
Traditional technology installation technologies imply a complete dismantling of the old coating and even removing the layer of plastering walls and floor, if it has some defects. However, there are situations when the old cladding can be saved. Denote them.
First, glue the tile in the bathroom on the old coating can be if it is preserved in a fairly good condition, if the old cladding is so strong that its dismantling will be associated with great efforts. During it, there will be a lot of construction garbage and dust, to get rid of which in apartment buildings is quite difficult. Before repair, it will have to be released not only the repaired room, but also adjacent rooms. Even if the entire setting, all the equipment in the house is firmly covered with polyethylene, dust, the appearance of which will necessarily cause a dismantling of the facing, still leaks and takes all items. In addition, the dismantling of the old cladding is always accompanied by a strong noise, which is also undesirable when repairing in houses of high floors. That is why the question of how to glue the tile on the tile in the bathroom, it becomes relevant for many.
Secondly, sometimes the old tile laying is made on a fairly fragile basis, the dismantling of the facing in this case will provoke the need for a major repairs requiring additional measures to restore the foundation. So, for example, along with the tile, there are almost always hidden layers of a screed, it will need to be done again, and this is additional costs and an increase in the duration of the repair time. If a national base equalization system was used during the floor cladding (with the help of plywood or plasterboard flooring, for example), it will also come to complete unsuitability after dismantling the old tile. Experts pay attention to the fact that the polymer fill will also have to update again.
Thirdly, it is necessary to solve the question of whether to implement the task, how to put the tile in the bathroom, it is necessary when dismantling the old cladding must be performed with a significant decrease in the floor level. This circumstance sometimes plays a fundamental role.
How to glue a tile on the tile
If you put the tile on the old tile becomes appropriate, it is necessary to act, according to the existing technology. It consists of several stages.
Preparation of the foundation
So, the first thing is important to make sure that the old glued tile is really firmly held. To do this, it is necessary to arm a rubber hammer and catch up with each laid module. If the sound is deaf, the scheduled event is possible. A ringing sound indicates that the old tile glue peelled, and the old tile holds on a good word. And what can I count in such a situation? For anyone, the new tile will not be able to put on the peeling tile. Therefore, we act as follows:
- "Rattling" tiles, tiles with chips and cracks dismantle.
- Clean the released cells.
- Align the floor in this section by cement-sand mixtures.
Note! Such a solution becomes appropriate when dismantled tiles have several pieces.
Another circumstance that needs to be taken into account before starting to lay the tile in the bathroom on the old tiled facing - the thickness of the wall-being repaired or the floor will increase at least 1.5 cm. At first glance, this is not much. But it can happen that after repairing in the bathroom, the new floor will be above the threshold of the entrance door.
If all the designated nuances are solved, you can begin to prepare for work. Old facing is cleaned from dust and dirt. Special attention is paid to the preparation of interputric seams. If they were filled with cement grouts, they first need to be treated with penetrating primer, the composition of which coincides with the composition of the Ceresit CT 17 brand. The surface of the facing is simply degreased. After the preparatory work, it is necessary to decide whether to glue a new tile on the old base.
What glue to choose?
Experts assure that each modern tile glue can be used to perform the task if the rough surface is porous or rough. Only it will be possible to ensure reliable adhesion of adhesive composition with old ceramic products. Therefore, the problem is not in choosing glue, but in solving the task designated above. What can be done in this case?
The main complexity is the absence of pores on the smooth surface of the tile. If she is covered with glaze, there is nowhere to penetrate with glue, nothing will be fixed and attracting a new coating. So, it is necessary to either open the pores, or create them, increasing the roughness of the tile. You can do this in the following way:
- The top layer of glaze on a tile can be cleaned with a grinding machine or a grinder, if there is something at hand.
- If the surface cannot be grinding, we make frequent notches on the front surface of the old tile.
- In the absence of special tools we buy primer enriched with needle quartz. There are such mixtures on sale, it is better to give preference to proven manufacturers and choose the compositions of the brand "Cerezit" or "Knauf".
Note! If possible, experts recommend using at once all three ways to create a base capable of providing the necessary clutch. Such an option must be considered when desired to attach or glue the tile to the tile.
Is such actions always justified?
When the solution of the task is found, everyone should be asked: "In my case, can you stick to the tile?" A positive answer occurs when there is no following contraindications:
- The old facing was produced poorly, therefore, there are small irregularities on the walls or on the floor. Permissible drops - 4 mm at a two-meter length. You can check the errors by applying a wooden rail to the surface of the facing. If it allows you to identify more specified numbers, take the perforator and get rid of the old finish.
- Do not put a new tile on the old tile, if it was covered with cracks, or the mold settled in the seams.
- Under the old coating there are communications, access to which is not. In this case, it is better to immediately abandon your venture and do as it should be on the laying technology.
To a similar list, plus a possible change in the heights of the new finish and get a complete list of existing contraindications. If such factors are not detected, you can proceed to the main stage of work.
The algorithm for laying tiles on the tile is no different from the installation of the tile on the traditional base. The exception is only the process of preparing the floor or walls.
It is useful to initially produce a dry layout of the tile, such an operation will allow you to understand whether it is necessary to cut the tile where to hide the cropped pieces.
Note! The new tile must be placed on the old cladding so that the top coating seams accounted for right in the middle of the one-piece tile of the old. The coincidences of the seams can be avoided if possible. If not, minimize.
We are reduced to a single indicator all of the above information and make up the correct sequence of basic work.
- First, we carry out the revision of the old base, unreliable elements are removed, we clean the square from the glue and fill the space of the cement-sandy mixture. We are waiting for a complete hardening of the solution (about one week).
- The folding seams we clean the chisel, the freed space fill in the new grout or glue, which will be used when installing a new coating.
- We in the hands of a grinding machine, install a disk with medium grain and process all the modules. Then they armed with a grinder and make notches on the tile.
- Thoroughly my foundation: First, we remove the construction dust with water, then we get rid of fatty contaminants with soapy water. If there are difficulties at this stage, add soda to soap water. After the surface, it is washed several times with clean water and swell dry.
- Next action - surface treatment with primer capable of increasing the adhesive properties of the old surface. It may be "concrete contact" of the brand "Cerezit". The primer is evenly distributed over the surface with a roller or mounting brush.
- We are waiting for the complete drying of the primer (3-4 hours).
- We divorce the glue, we apply it to the spatula on the base of the floor or wall.
- The first tile is pressed with a lot of effort, correct its position until the glue grabbed. Then secure the second method, and all subsequent modules. Do not forget to leave the surmise space, inserting plastic crosses between the tiles.
- Seams process in a suitable grout.
Note! Dry glue should be naturally, without additional heating or ventilation. Moisten the tile after laying no longer needed.
Generalization on the topic
The success of the work done will largely depend on how the proposed briefing was performed. Only when implementing the proposed plan it will be possible to repair the old base in record time and after five days to see the results of their work.
In the process of carrying out repair work, it is necessary to deal with many complex questions, the correct answers to which will determine the quality and service life of the new trim. One of these questions - is it possible to lay a tile on the tile? Consider whether it is possible to use an old tile as the basis for a new coating or still better disassemble it to avoid possible problems.
For which it may be necessary to preserve the old tile
There are several significant reasons that create a reason to think about abandoning the dismantling of an old coating before laying a new one. Preferably, these are economic factors, including:
- significant time savings and efforts spent on repair work;
- Most likely, in the disassembly process, you will have to face chopping individual pieces of cement-sand tie. This will entail additional work on its replacement or partial recovery. Also, if the prefabricated leveling system from plasterboard and plywood was used, it will need to be replaced;
- In the process of work, dusting will be minimal, which cannot be said about the cases when the old tile has to be removed. In this case, it will be necessary to fully release not only the place itself, but also related to it, since often the coverage of objects of furniture and equipment with polyethylene is not enough;
- Saving the old coating can avoid the need to deal with the export of construction garbage;
- It happens that wait for a period of time required for the full sprinkle of the new screed. In this case, it is also better to use the old tile as the basis.
Thus, the reasons to keep the old coating can be found quite a lot. The main thing is to rather estimate whether it is possible to put the tile on the tile in this case so that as a result, the resulting coating was solid and reliable.
Is it possible to lay a tile on the tile: the evaluation of the old coating
In order to determine whether it is possible to lay a new tile on a layer of a similar coating, it is necessary to preview having a base. First of all, you need to make sure the strength of fixing all elements. It is necessary to draw attention to the presence of any, even the smallest chips, cracks and fastenly fixed elements. To do this, each tile must be sprinkled with a rubber hammer. Bad elements will rattling.
All items that are not well fixed are fixed or have cracks, necessarily rock. It is necessary to make a decision on laying a new tile on top of the old on the basis of how big the percentage of the old tile is in good condition and securely holds.
Useful advice! Pay attention to the available floor level. As a result of the installation of an additional layer, its height should not exceed the height of the threshold. If the thickness of the floor cover is too high, then before laying it will be better to dismantle the old coating and put a new tile directly on the base.
Is it possible to lay a tile on the wall on the wall: the features of the work
The main complexity with which you have to face in the process of installing a new coating on top of the old - the impact of the force of attraction, because with time the tile will give a shrinkage, and the old base should endure it. Therefore, it is necessary to ensure the highest possible adhesion between the layers. It is first necessary to take care of the stripping of the seams, at least partial removal of the glazed layer of tile and purchase the concrete contact.
Useful advice! Concrete contacts are usually applied using a spatula or celma, thoroughly throwing it into it so that the layer applied is as uniform as possible. Consumption should be approximately 300 grams per 1 m².
If the laying of the new floor covering is not planned, in the process of laying a tile on the wall, the floor must necessarily require protection. Plinth and sexual coating need to be seen with a polyethylene film to avoid the appearance of specific, and practically nothing from the spots.
In the case of working with the surface of the wall, the period of drying of the concrete contact should be at least 5-7 hours. It is better to give preference as a dense synthetic modification as possible.
Otherwise, the laying of the tile is carried out in the standard way gradually in small parts of the wall. This is due to the high speed of drying the adhesive composition. The elements are laid out on an area of 1-1.5 m² and pressed with some effort. Before the moment the glue finally freezes, some irregularities and imperfections can be corrected using a rubber image.
Thus, answering the question or can be labeled the tile on the wall on the wall, the focus is on technology and the intricacies of this process. If you follow the recommendations of specialists, the result of the work done will be more than satisfactory.
How to put a tile on the tile: surface preparation features
Making sure that the old coating will withstand the estimated load and is in good condition, you can move directly to the preparation of the surface for laying a new tile. First of all, it is necessary to take care that the surface can provide the necessary level of adhesion, giving the old cafél the roughness. It is possible to achieve the desired effect in several ways:
- removing from the tile upper glossy layer;
- Taking advantage of a special primer for surface treatment;
- Having made on the tile of notches.
Each of these methods has its advantages and disadvantages. So, the easiest is the use of primer, but it requires financial investments. Others two do not require costs, but are associated with significant physical efforts and a large number of dusty work.
Remove the top layer of the tile, how to make the necessary notches, you can only with the help of a grinder. These procedures make it possible to create the necessary contact between the lower layer of the new tile and the old coating. It is not necessary to remove the entire top layer at all. It will be enough will be 60% of the surface of the tile. As for notch, they are located at a distance of 1-2 cm apart.
A simpler and clean method - the use of primer under the tile. The composition, which is also called concrete contact, is able to give the necessary properties of any smooth and waterproof surface. With the glazed surface of the tile, this composition is perfectly engaged, creating a grungy layer from above, which serves as the basis for tile glue.
How to stick a tile on the tile: step by step instructions for work
Tile laying technology on old tile implies the following sequence of actions:
- Using cement-sandy solution, all the locations of chips, cracks and irregularities in such a way as to align the surface as possible. After that, it is necessary to wait for a complete drying of the solution and clean the old coating, paying from it all pollution, lime deposits and moisture.
- Using one of the possible ways to ensure adhesion, handle the old coating. As already mentioned, the easiest to use special primer for this purpose.
- A smooth spatula, tile glue is applied to the opposite side of the tile, after which the composition is spacing over the entire surface and create special grooves on it using a toothed spatula. Simply put, at this stage, the tile laying is made according to the standard technology.
Useful advice! If we are talking about partial removal of glaze or notches, then in the process of work, the means of individual protection against small pumping particles and dust must be used.
It is important to know that on the complete drying of the adhesive composition in this case will require more time. This is connected with the low ability of the basis to absorb. That is why all the works related to the grouting of the seams are best carried out not earlier than 3-4 days after laying. At the same time, the standard technology is fully maintained, which involves the use of a special composition and rubber spatula.
How to understand that you should not glue a tile on the tile: recommendations of specialists
Before glue the tile, each owner wants to be sure that his work will not be in vain, and the new coating will regularly serve for many years. That is why it is necessary to first get acquainted with the recommendations that specialists give. They point to those aspects that may interfere with reliable fixation of the elements and serves as a warning signal to pay attention to:
- In the process of climbing, the tile retains integrity, but the sound that is heard is heterogeneous. This may indicate the presence of air emptiness under the tile, which can later lead to its destruction. The thing is that the old solution may not withstand the load and as a result, both coating layers will fall;
- Most often the question arises whether it is possible to lay a tile on the tile in the bathroom or in the toilet. In this case, it is necessary to pay attention to the size of the room, because these rooms are quite rarely spacious, which means an additional layer of solution and facing material will reduce the already small area of the room. So if you see in advance that this method will affect the size of the room, it is better to remove the old tile and put a new one according to all the rules;
- A bad base is the old, cracked tile, the upper layer of which has natural damage and is inclined to the appearance of chips. If you put another layer of the tile on this basis, it is most likely to last long, and in the near future all work will have to redo. And this will entail not only the significant costs of time and strength, but also financial expenses;
- Before putting a tile on top of a layer of old facing material, you need to make sure that it does not prevent free access to all communications and revision hatches. Otherwise, the slightest breakage will lead to the fact that for repair work, both layers of tiles will be removed at once. In this case, it is wiser to consider everything in advance so that in the future I did not have to face such serious problems;
- Do not put a tile on the uneven floor. No matter how hard you tried, the situation with a bias is only aggravated by an additional layer, therefore it is better to pre-dismantle not only the tile, but also the old tie. After repairing properly, you can fix the existing overcast. It is also worth paying attention to it before putting the tile on the uneven wall.
Having considered all these recommendations, it can be concluded that before proceeding to laying the tiles on top of the old tile, you need to thoroughly weigh all the arguments. The risk that the old coating will not endure the load and simply fall off, destroying at the same time and the new layer is always there, and it is better to think over all possible options in advance so that if necessary, refuse this idea.

How to remove old grout from seams tile
Quite often to face the situation when the state of the old tile is quite satisfactory, but in order to use it as a basis for a new coating, it is required to replace the grouts for seams. Conduct this procedure is quite possible, however, it requires attention and time. Consider how to remove the grout from the tile seams correctly.
In order to remove the old grout, there is a special tool called "Schedules". With it, you can remove the grout mechanically. By itself, it represents a blade with a comfortable handle, but an ordinary knife can be used as an alternative.
The blade of the knife or the frameter must be walking on both sides at an angle and directly. It is necessary to abide by caution in order not to spin the edges of the tile. It is worth noting that it will not work "manually" quickly, so you can use a drill with a thin drill or electric chisel.
Important! If, in the process of removing the old grout, the tile also began to crumble, it is better to abandon the idea to put another layer from above even if there is a new grout.
How to remove the old grout from the tile seams, if it is silicone
Silicone grout also requires dismantling and replacement, especially if high-quality ventilation has not been provided in the room. Very often have to face that the seams are affected by mold, remove which is almost impossible. Therefore, before laying a new one on top of the old tile, you need to take care of the hygiene of the seams.
The removal of silicone sealant is carried out with a sharp knife or a special scraper. After that, additional cleaning is performed using a vacuum cleaner.
Useful advice! There are special means to eliminate silicone faster and with less effort. Such formulations are applied using a mounting gun, after which it is necessary to wait at least 24 hours. The seams are then rubbed with a cloth or paper.
Is it possible to lay a tile on the tile on the floor: features
Outdoor coating, unlike wall, is not exposed to the strength of attraction. Therefore, in some sense, laying is easier. But in this case, another complexity occurs - the new coating will be regularly subjected to serious loads.
Before gluing a tile on the floor, you need to carry out no less thorough check of each element of the bottom layer. To do this, you can use the same hammer to climb, but you can try another approach: a flat base (a box is well fitted), you need to smoothly drag on the surface, carefully observing that no tile fails for several millimeters. Make it in a small bathroom or bathroom is difficult, but for larger premises, this is a very effective way.
In general, all the recommendations that are provided in the previous section are relevant and in the case of work with the floor. It is advisable only to give preference to mineral compositions. Thus, the surface will be ensured greater elasticity, which will allow it to withstand heavy loads and temperature differences.
Useful advice! Before putting outdoor tiles on top of the old ceramic coating, you can not carry out so intense preparatory work as in the case of the wall surface. But to moisturize the basis before proceeding to applying glue, it still costs, as it will have a positive effect on the clutch.
Is it possible to make a bulk sex on the old tile
As a basis for a new coating, a bulk floor can be used, the installation of which is carried out directly to the surface of the old tile. As in all previous cases, the mandatory procedure is a thorough check of the quality of fastening the lower layer. All loosely adjacent elements are necessarily disassembled.
It is worth paying attention to the fact that in cases where it is about working with a glossy surface, the upper coating layer is removed to ensure the necessary level of adhesion between the solution and the cafenel. Filling and further work is carried out according to the standard algorithm.
Useful advice! For laying a new layer of tile, a thick layer of bulk sex is not required. Its thickness should not exceed 5 mm. The main thing is to evenly distribute the composition over the entire surface.
Taking into account the opinion of specialists, it can be said that it is possible to make a bulk floor over the tile only in extreme cases. At the same time, the area of the room should be small, and the requirements for the operational characteristics of the surface are minimal.
Is it possible to lay a tile on the tile on the street
A very interesting question that may occur - can we put a new layer of paving slabs on top of the old one. Of course, such a procedure is often unreasonable, but in some cases this technology is resorted to the process of arranging garden tracks, terraces and summer sites.
As in the case of a tile laid on an old coating inside the house, the main criterion is the quality of fastening the bottom layer. You can conduct a check by using the mounted or a durable knife. Using such tools you need to try to remove one of the items.
Important! If the tile managed to shift with a knife, but for this it was required to make serious physical efforts, such a coating can be used as a basis. If the tile took off easily, in the future it may cause the deformation of the upper layer.
On top of the old layer of tile, a new pillow is embanked, which should consist of three layers - loose soil, gravel, sand. At the same time, the seal of each layer is necessary separately. From above, according to standard technology, a new layer of paving slabs is stacked.
Thus, the answer to the question is whether it is possible to lay a tile on the tile on the floor in the bathroom or even on the walls, rather an affirmative. Of course, in the process of work, many rules and recommendations will have to be observed, and the final result can almost always be unpredictable, but in principle, it is quite possible.
Repair is a troublesome, taking a lot of strength, time and money. That is why many who make it independently try to simplify the task as much as possible and often glue the fresh wallpaper on top of those who have lost sight of old, equip the new flooring over previously laid. But, unfortunately, it is not always possible to update the apartment in this way and bring it to the divine view. Is it possible to put a tile on the old tile on the floor? The question is relevant to those who plan to update the floors in the bathroom or in the kitchen, but want to save time and money on the dismantling of the old coating.
Is it possible to put the tile on the old tile on the floor
Why is the question about laying tiles on top of the old relevant?
Decorative beautiful ceramic tile - the material is very popular for the arrangement of floors and walls in places such as kitchen and bathroom. It is durable, easily cleared, for a long time does not lose its beautiful appearance. However, over time, the same surface, the appearance of which does not change, can seriously bored. And if the design of the room is radically updated, the old coating may simply not go under a new format. In these cases, nothing else remains how to put a new tile.
Laying tiles on old tile
And here just and often the question arises - а Is it possible to update the coating without removing the old ? After all, the dismantling of the tile is a heavy, troublesome, associated with the appearance of a large amount of garbage work. The main reasons, because of which you want to keep the old coating, but close it new, the following:
- savings not only time, but also money;
Economic Backgrounds Conservation Coating
- The complexity of the removal of an old coating, which is often associated with the fact that it will have to remove the remains of the cement mixture - it was before her a ceramic tile was previously laid in 90% of cases;
- the need to align the base after removing the tile to be able to put a new ceramic coating;
- the formation of a large amount of garbage;
- If necessary, the fill of the new screed will have to wait for its drying for a very long time.
As can be seen from everything written above, The question of the preservation of the old tile coating is really relevant.
Old tile on the floor
Is it possible to leave an old coating?
There is no unambiguous answer to this question. In general, many masters speak out against such a way to save, but no less people practiced this method of updating the floor covering - they, without removing the old tile, put on it a new one. But here it is important to soberly assess the possibilities of laying.
The decision is made on the basis of the state of the old flooring.
For example, if the old surface is in excellent condition, smooth and neat, then put on it a new tile, subject to simple rules for the execution of such works. However, if the floors are in a terrible state, some of the old tile is absent or has chips, and the voids are clearly felt clearly, then the "dry out of the water" will not work. In such cases, laying the tile on top of the old one in no case.
On a note! It is possible that due to voids that may be under the old coating, cracks may appear on a new one with some mechanical exposure. It is possible to identify the presence of emptiness by tapping a rubber hammer tile.
Often old tile should not leave
If there is no emptiness, then the old tile may well perform excellent durable and even base for laying a new layer. Also, thanks to this "black" floor, it is possible not to be messed with the performance of waterproofing and other works - for sure when laying the previous layer, all these works were performed. By the way, in certain cases (for example, if there are some communication under the cafeter, and it is impossible to determine the location of their occurrence) the removal of the old coating becomes almost an impossible problem.
Removing the tile planted for glue
You can not put a new tile on the old one, if the latter is very bad on the surface - cement with time due to the permanent operation of the floor could simply be reassigned. And it is not recommended to use this method if there is no desire to reduce the height of the ceilings - sometimes raising the level of the floor, even a couple of centimeters can interfere with normal closure of doors, etc.
Important! In the bathroom or bathroom, the floor level is usually lower than in other rooms at home or apartments. This is done so that in the case of flooding water does not hit other rooms. It is necessary to leave the threshold!
The process of laying outdoor tiles
In general, we can say that laying the tiles to the surface of the old may well have a place to be. But only in the event that it is possible to put a new coating without the risk of damage.
Table. Absolute contraindications for such work.
|Flawing tile||The new tile will not hold on to the surface of the old.|
|Empties under the tile||The fresh layer will quickly collapse and come into disrepair, as the tile under it may fail and break under the influence of the weight of the person moving around it.|
|Previous tile is laid using bad glue||If it is known that the previously laid tile is mounted with a bad glue, then it is not worth putting one more layer on it. It may well be that soon the old tile will begin to lag behind that he will entail a violation and an external layer of a new tile.|
|Uneven floor||If the old tile coating is obviously uneven, then the laying of the new tile cannot be made over the old one. The base should be perfectly smooth.|
|Old tile is covered with cracks||In such cracks, dirt accumulates, and the old tile itself can no longer be reliable and dense base for a new one.|
Removal of damaged tile
In the presence of contraindications given in the table above, the dismantling of the old coating is a mandatory measure. Otherwise, the new base will not last long.
Difficulties of work
Despite the fact that in general the lack of need to remove the old tile will greatly facilitate the life of masters, there are their pitfalls here. So, for example, that the new tile layer will be good and efficiently, it is important to conduct certain preparatory activities.
Is it possible to lay a tile on the tile laid with violations
To begin with, you should evaluate the condition of the previously laid coverage . It must be high-quality, durable and reliable. Next, it is necessary to eliminate all available irregularities, if possible.
It is also important to remember about such a factor as adhesion . Often a ceramic tile on the floor glossy and smooth, and therefore the adhesion of glue with it will be bad. Such a surface will have to be mastered, to make a rough, otherwise no speech about quality work can simply be. The glue is simply not able to securely attached to a completely smooth surface. Thus, it is necessary to prepare for the fact that we will have to create this very roughness, pouring the surface with the help of a grinding machine, forming notches and inflicting the primer.
Formation of notches on the tile
On a note! The ideal option is to use the three methods of creating roughness. Then the adhesion of glue and the new tile with the old will be the maximum.
Wrongs on the tile can be made by an ordinary grinder. It is necessary to position them about 1-2 cm from each other. In general, to achieve the desired result, it is enough to cover about 60% of the entire old surface to be covered with notches. The work is dusty, and you need to do it, putting the respirator.
It is also recommended to hold and degreasing , and also - Careful surface cleaning from all sorts of spots (for example, paint spots), garbage. Vacuum is recommended after stripping the surface. Degreasing is important, since over time, an imperceptible fat layer is formed on any surface. And fat negatively affects the adhesive ability of adhesive compositions. Especially important degreasing against the seams between tiles. If the fat from the surface of the old tile will be removed during the creation of roughness, then from the seams it will not be so easy.
Tip! To degrease the floors, they can be rinsed with water with the addition of a small amount of caustic soda.
Tile and tools
In the presence of an overlapped grouting between the old tiles, it must be removed. Moreover, try to do it at the maximum possible depth. And when the old tile is prepared in this way, it can be covered with its "concrete contact" to create a high-quality primer layer. Some masters note that by covering the tile of such a composition, you can do without creating roughness, but it is better not to neglect this measure if you want to get an excellent result. Consumption of "concrete contact" is approximately 300 g / m 2.
Selection of glue
Choose glue - also a kind of task for a master who decided to lay a new tile on top of the old. Here is not suitable for any makeup, which can be bought in the first thing you caught the store. So, when choosing glue, it is important to draw on the recommendation to use it - it must be written for which surfaces it is suitable.
It is important to choose good tile glue
Specialists recommend taking Cepese SM17 or IVSIL PROFIT as the best adhesive compositions for this type of work. Let not bother that the second version of the adhesive composition is designed for porcelain stoneware - in this case it will be only on hand when working. And the ceresit is great for working on complex surfaces to which the old ceramic tile belongs.

Stages of work
As such standards and recommendations, and even more so, there are no instructions for laying a new tile on the old age. Most Masters have its own technology for such work. Consider one of the options step by step.
Step 1. First you should prepare all the necessary tools. These include Bulgarian, drill, level, must necessarily need a marker and roulette. Also use tilecores and mysteries, a metal brush for a drill, spatulas and a spatula-comb (12 mm) for applying glue, as well as adhesive itself, a new tile and cross-demarcaters for the formation of beautiful seams. It will come in handy and grouting for seams, which will be used at the final stage.
Step 2. Next, you need to start conducting preparatory work. To begin with, it is recommended to put on a drill a special metal brush-nozzle and with it to handle the floor surface. This will allow you to get rid of the solar dirt and paint spots on the tile. You need to handle the entire surface of the old floor. It is recommended to work in a protective respirator, since the stage is associated with the formation of a large number of small dust. After that, it is important to remove all dust from the floor.
Step 3. If part of the old tile dropped, then you need to align the base before installing the new tile. To do this, use the tiled glue, the layer of which is applied on the area of the tiles of the tiles and is aligned to the level of the rest, fixed tiles. If there are tiles that keep badly, it is important to remove them, and the voids formed also to align glue. To align the layer of tile glue, you can use the usual rule.
Alignment of tile coating
Step 4. The prepared layer of the tile should be covered with the composition of "concrete contact". It is possible to apply it with a tassel, thoroughly missing the entire basis. After that, the surface of the tile must be well dry, and you can start further stages of work.
Application "concrete contact"
Step 5. Next, you can start laying a new layer of tile. A small amount of tiled adhesive with a spatula must be placed on the floor.
A little glue laid on the floor
Step 6. Then, with the help of a spatula-comb, a layer of tiled adhesive should be confused on the surface evenly. Moreover, it is best for every 1-2 new tiles every time to apply fresh glue every time, it is not necessary to smear it immediately to a large area - it will only complicate the work, but it will not speed it.
Tile glue rubs on the floor
Step 7. After that, you need to take one new tile and put it on the layer of glue, and then - to press a little. Additionally, the tile can be hosted by the image.
The new tile is stacked

Step 8. Each time, laying a new element, it is necessary to check it on "evenness" with the help of a construction level.
Each tile is checked by the level
Step 9. Thus, step by step performing the actions of paragraphs 5-8, you need to lay the tile of rows from one wall to the other in accordance with the selected pattern.
Similarly, the rest of the tile is stacked
Step 10. Do not forget about the cross-separators. They are required to insert between near the underly tiles during the laying of the material. They will allow to achieve smooth and neat seams.
Cross-separators are inserted
Step 11. Next, you need to leave the floor surface alone and give glue to dry. And the final stage of the work will be putting seams. Paul is ready.
In the end, it remains only to sweep the seams.

Video - how to put a tile on top of the old
Laying a new tile on the surface of the old has a place to be in certain situations. And, as can be seen from the material above, it is not difficult to fulfill such work. It is definitely much easier than to dismantle the old coating before installing a new one. However, it is important to remember about the contraindications regarding such work and if they are presented - to abandon laying a new coating on top of the old.
Laying method tile on the tile: selection of materials and features of technology
Tile on the tile - such a technology is a rapid way to facing the room without the need to carry out dismantling "dust work". Modern building materials fully allow such installation. However, the nuances should be taken into account, on which the possibility of holding such an event depends. It is also important to ensure the right preparation, choose suitable materials and comply with masonry technology. We tell all this in publication.
In which cases you can put a new tile on the old
The first step to laying tiles on the tile is the primary assessment of the state of the existing facing. In particular, two mandatory rules must be performed:
- The old tile should have a smooth masonry, without significant drops between fragments. The presence of drops of more than 5mm can adversely affect the quality of the installation of a new tile on top of the old. This is due to the fact that the tile glue can give a small shrinkage. With different thickness of the shrinkage layer, respectively, will also be different. As a result, the surface will not have the necessary flatness, and the lining will look not quite aesthetic.
- The old tile must be attached to the base tight. Lufts, chatting and easy stroke when pressed on a fragment are unacceptable. During operation, this will result in cracks in tiled glue and peeling a new fragment. Even if the old elements do not dangle when pressed, it is recommended to check the strength of their holding with the clutch - with the help of a rubber hammer. Easy shock loads should not lead to departure fragments.
If these conditions are observed, you can proceed to the arrangement of tiles on the tile. As in any other construction work, the laying is performed in two stages - preparatory work and direct installation.
Preparation of old tile under a new laying
Most often, the tile is used as a facing material in wet rooms, like bathrooms, and in kitchens. In the process of operation, pollution, fat, soot, film from torn materials (household chemicals, soap divorces, remnants of personal hygiene are accumulated on the surface of the walls and floors. In addition, in the process of repairing the tile, construction trash can fall, residual solutions and similar pollution. All of them must be eliminated at the preparation stage.
In preparatory work, it is recommended to conduct three main actions:
- Processing of tile seams;
- Surface ripping;
In tile seams over for many years, dirt accumulates, fat, bacteria are formed. For this reason, they need to pay attention to preparing. If possible, the old grout is best to scrape, using a narrow chisel, a metal brush, grinding circles in the power tool.
The sprinkling of the surface is carried out by mechanically. For this, the drill or bollard is best suited) with a brush-cup . It is recommended to use a steel bristle nozzle. It is tougher, which makes it possible to better remove the dirt, the remains of the construction solutions.
At the stage of the ridges, it is important to get small scratches-notches on the glazed glossy tile. Subsequently, they will strengthen the grip with the soil and make the tile laying on the tile more reliable. Such notches can be done by sanding the medium grinding sheet Using grinding or grinder. More effectively cope with the task of the grinding cup with diamond segments . When working, it is necessary to use the means of personal protection of the respiratory and eye organs, provide high-quality air ventilation.
Degreasing is the final stage of preparation. It lies in the residual removal of plaque, fat, and other contaminants, which negatively affect adhesion. Degreasing the surface is carried out using a soap solution in water. You can use inexpensive liquid soap , diluted in a small proportion. After treatment with a soap solution, the surface is thoroughly washed out 2-3 times with warm water until complete removal of traces.
Installation of a new tile on the old tile
Installation of a new tile on the old one should start with surface alignment, in places with missing fragments. Such "voids" is initially ground with universal compositions. It can be:
- The soil is a deep-perky Ceresit CT 17 - levels and reduces moisture absorption, strengthens and dusts loose bases.
- Unice for internal works. Universal soil for cement screeds, plasters. Suitable for the processing of a new hardened tile glue, reduces the surfaces of the surface, is dedicted, increases adhesion.
After leveling the tile glue, it is important to wait for it to complete hardening. Depending on the recommendation of the manufacturer of the adhesive composition, it can be 12-24 hours. Next, the surface is again processed by primers of deep penetration.
The next step is to apply a special type of primer "concrete contact" on the front surface of the old tile. It is possible to carry out the procedure with a brush or roller, carefully following the uniformity of application. For convenience, manufacturers of such primers add pigment to their composition (usually pink). Thus, the possibility of simple visual control over the presence of "spaces" in the layer is achieved.
Selection of concrete contact for mounting tiles on tile
Not any concrete contact can be used to lay tiles on the tile. In particular, manufacturers of some brands limit the scope of application of their products with plastering. The use of such products for mounting tiles is fraught with negative consequences, namely peeling tiles during operation. According to the aforementioned reason, when choosing and purchasing, we recommend paying particular attention to the instructions of the manufacturers on the use of primer.
For laying on the technology "Tile on the tile" is recommended to use:
- Concontact Ceresit CT 19. Suitable for outdoor and internal works. Provides increased clutch with materials, has a direct manufacturer's recommendation on the possibility of applying the composition for masonry tile on the tile.
Selection of tile glue for tile tiles
For a good retention of a new tile on the old, it is also important to choose the right tiled glue. In particular, the mixture should have sufficient clutch (at least 1 MPa) and elasticity. From suitable brands of glue for tiles can be used:
- Ceresit cm 16 elastic. Recommended by a manufacturer for masonry by a tile on the tile. It has adhesion at least 1 MPa, elastic, resistant to the formation of cracks. Additionally, reinforced with reinforcing fiberglass, which increases the reliability of the masonry.
- Unice Granite. Characterized by increased adhesive ability. Clutch strength is 1.5 MPa. At the same time, the layer retains elasticity, suitable for warm floors, using the outside of the room, masonry tile on the tile.
- Knauf Flex. Durable and elastic composition recommended by the manufacturer for mounting on ceramic tiles and porcelain stonewares. It has a high adhesion of 1.5 MPa, weather resistance, frost resistance.
- EK TITAN 4000. It has a direct indication of the manufacturer on the possibility of using glue on the old cladding. It has increased adhesion in 1.5 MPa. Good viscosity allows you to install the tile by the "top-down" method.
Tile laying on tile
The final stage is the direct laying of the tile. Pre-sliced fragments are mounted on the prepared surface in the same way as on walls or floors without old tiles. All the subtleties and nuances of the installation are described in detail in our publication: installation of tiles and porcelain stoneware: from beginning to end . We hope to prepare the material will help avoid mistakes when laying tiles on the tile, perform work with high quality and get a durable cladding.
