Is it possible to lay tiles on old tiles? Laying tiles on tiles - new renovation on old

When it comes to installing tiles, one of the main requirements is careful preparation of the base on which the tiles are planned to be laid. According to building regulations, the base must be cleared of old coating, checked for horizontalness, and leveled cement screed and treated with a primer that improves the adhesion of tile adhesive.

If for new housing this option is undeniable, then for already exploited housing it represents a great difficulty and even a “headache”.

Problems with removing old tiles

Nowadays, it is rare to find a bathroom or toilet where the walls and floors are not tiled. And the need to remove it disheartens every owner of such housing.

After all, this process is associated with a lot of inconveniences:

The work involves the use of impact instruments, which means it will be very noisy, which cannot but cause complaints from residents of neighboring apartments.
During work, a large amount of dust is generated, requiring isolation of all rooms adjacent to the repair site.
Removing old tiles can lead to damage to the screed underneath, which will have to be partially or completely repaired.
It will be necessary to remove fragments of tiles and the removed layer of adhesive.
Repairing or restoring an old floor base will require new materials, effort and time, which leads to additional material and time costs.

Therefore, both apartment owners and renovation workers could not help but be tempted to use old tiles as a base for installing new ones. An annoying obstacle to the implementation of this idea is the low porosity of the tile surface, which does not allow reliable bonding of the fresh adhesive layer to old tiles.

The ability of a solid material to absorb water is directly proportional to the number of pores in it. For tiles intended for finishing surfaces inside a building, it varies from 0.5 to 3%. The upper surface of the tile, including the floor tile, is most often covered with a layer of glaze, which ensures the waterproofness of the tile layer, which is necessary for wet rooms.

In order for the glue to be able to properly attract the new topcoat to old basis, it must penetrate through the pores into the body of the base. Therefore, it is necessary that its pores are open. Surface roughness is also important, improving adhesion.

How to achieve these goals in the case of old tiles?

To do this, you can use the following methods:

Remove the glaze layer from the surface of the old tile using a sander.
It is also advisable to form notches on the surface of the old tiles.
Handle old surface primer "Betonokontakt", enriched with sand particles, and even better - needle quartz. After such treatment, the surface acquires the necessary roughness, after which it becomes suitable for adhesion to tile adhesive.

The latter method allows you to save a lot of time and effort and reduce the time required to carry out repair work. But if all three methods are used in a comprehensive manner, then you won’t have to worry about the result of the work. However, these are not all the conditions under which you can use an old tile as a basis for gluing a new one.

All of the above methods for preparing the base can be used only if there are no certain defects.

The floor is uneven, that is, the differences in its surface are more than 4 mm per 2 m of the slats applied to the surface. If less, then the primer and glue will be able to level out the differences.
Old tiles are covered with cracks in which many years of dirt, grease, and possibly mold have accumulated.
Tapping the surface reveals voids under the layer of previous tiles. If there are many such places, the floor will have to be completely dismantled. In the case of individual places, the tiles are removed here and the surface is leveled with a screed.
When installing old tiles, poor-quality glue was used and the tiles were “loose.”
During the previous renovation, communications were laid under the floor, but inspection hatches were not provided. The floor must be completely dismantled.
When sticking new tiles the floor level rises so much that it becomes above the threshold. This will not allow you to freely use the doors. In addition, the floor level in the bathroom and toilet is usually lower than in neighboring rooms. This is done to prevent spilled water from immediately and unimpededly flowing into adjacent rooms.

Very an important condition In this case, there is a discrepancy between the seams of the previous tile covering and the seams of the newly laid one. Therefore, during the period of preparing the tiles for work (cutting them to size), you need to draw a floor plan with all its inherent features. Then the new tiles are laid out on a dry surface in order to place the cut pieces in inconspicuous places, taking into account the overlap of the seams of the old floor.

Then the work is carried out as follows:

The crumbled seams of old tiles must be cleaned out with a chisel and filled with tile adhesive or cement mortar.
Old tiles need to be thoroughly washed from dust, first with just water, and then soap solution. Oily stains You can clean it with baking soda. After this, the entire surface is washed again with clean water.
The cleaned surface of the base must be treated with a primer with additives for roughness. To do this, you can use a brush or roller. Material consumption is approximately 300 g/sq.m. m. Based on the area of the new floor, calculate required amount primers are easy.
On small area tile adhesive is applied to the floor. Please note that it dries quickly, so the area of the area should not be more than 1 square meter. m.
Next, forcefully place the first tile in place. While the glue is fresh, its position can be adjusted if necessary. Next, glue the following elements, which should be located next to it.
Don't forget to leave between the tiles expansion joints. If necessary, use special crosses.
A day after installing the new tiles, you can start filling the joints with jointing mortar or a polymer composition.

Thus, if a number of conditions are met, a new coating can be laid on a layer of old tiles.

But its quality and durability depend entirely on how thoroughly the old coating is examined and how carefully it is prepared.

If there is even the slightest reason to believe that old tile poorly laid or does not hold firmly, it is better to completely dismantle it and lay a new floor using conventional technology.

A material for interior decoration, the demand for which is beyond doubt - decorative tiles from ceramic materials. With its help, the design of a bathroom, kitchen, or hallway will be not only practical, but also beautiful.

High-quality laying of tiles floor tiles– not an easy task, the implementation of which requires special training, experience and certain knowledge. In order for the work to turn out neat and aesthetically pleasing, you need to act carefully and carefully. You also need to know whether it is possible to lay tiles on tiles. A positive answer will reduce repair time and costs.

Often during repairs a situation arises when there is a clear need to replace old material, but removing it is quite difficult. The inability to remove dust and debris and lack of time stop the owner and force him to postpone repairs. In this case, it is quite appropriate to lay tile on tile.

Possibility of use

Dismantling the old coating takes a lot of effort and time, so the question of laying new material directly on the old one arises quite often.

Removing tiles is a rather labor-intensive process

This is possible if the situation is as follows:

the old coating has no defects, its condition is close to ideal - the tiles lie tightly, the grout does not crumble;
the process of removing the coating may cause irreparable damage to the premises or part of it;
dismantling is hampered by installed plumbing equipment;
with complete removal of previous finishing materials there will be a significant drop in floor level.

Coating entails re-pouring the floors and covering the walls liquid waterproofing. The time spent on repairs will increase, and the cost estimate will become significantly higher. To avoid this, you can lay ceramic tiles over old tiles, but only if the outdated coating is in good condition and can withstand the load.

Substrate quality

If the old coating is wobbly and the grout material falls out of the seams, laying a new one without removing the previous one is impossible.

Unreliability of the base will cause carelessness in laying the new coating. To understand whether it is possible to put new ceramic tiles on old ceramic tiles, it is better to carry out an audit.

The steps should be as follows:

Careful inspection of the surface of the walls and floor.
It is necessary to show maximum attention, pay attention to every crack and other defects.
A thorough inspection of the seams between the tiles and their condition is also important.
Tapping the surface with a hammer.

If the sound changes from dull to voiced, this is a direct indication of tile delamination. Laying new tiles without removing the old ones is strictly not recommended.

Check using building level spatial arrangement of walls and floors. In case of severe deviations, the previous coating must be removed and then the coating must be leveled with a special compound. This is difficult to do with tile adhesive.

If upon inspection of the surface no defects are revealed that do not allow gluing, you can begin work, but first the ceramic tiles must be prepared.

Lay new tile on top of old one

Surface preparation

The technology used to lay new tiles over old ones is somewhat different from traditional ones. The difference is that the tile covering on which the adhesive is applied must be rough. To achieve this effect, you can use the following methods:

Removing the top glossy layer. If it is absent, nothing will interfere with the clutch.
If you have difficulties with complete removal glazed coating can be applied to previously laid tiles.
In some cases the best option is to apply a good primer to the surface of the old coating.

Applying a primer over the tiles will help make the job better.

All options are not high-tech processes. Anyone can do all this. If the first two methods are not suitable for a reason large quantity dust during work, the third method is perfect.

It, unlike the first two, will require certain investments, since a good primer composition is not cheap. In any case, such surface preparation will improve the adhesion of already laid tiles to the new surface.

How to put it correctly

There are some technological requirements for the tile laying process.

Treatment of chipped and damaged areas. It is ideal if cement-sand mortar or tile adhesive is used for such treatment. After the solution has completely dried, you can move on.

Complete cleaning of the surface from contaminants in the form of adhesive residues. First you need to clean them, then thoroughly wipe the surface.

Application of concrete-contact primer.

A roller or regular brush works well for this. Drying time – up to 4 hours. To process bathroom tiles correctly, you need to carefully read the instructions.

If you select to enhance adhesion mechanical method, you need to use a grinder to make notches or remove the top layer of coating. The body and face must be carefully protected so that parts of the tile do not get into the face.

After everything preparatory activities left behind, laying new tiles. Further stages of installation are carried out according to the traditional scheme. It is important to remember that when laying in this way, drying adhesive composition will take longer, so finishing stitches will become possible no earlier than after 3 or 4 days.

When not to put

There are cases when laying tiles on top of old ones is not recommended.

The presence of a ringing hollow sound when tapping the tiles. Even if no damage is found on the surface of the tile, it is better not to install it. Air gaps under the tiles will prevent the two layers of coating from holding together, and the tiles will simply fall off after a certain time.

Small room dimensions or uneven surface.

In case of a small room area, it is necessary to remove the tiles, since the second layer will lead to an even greater reduction in area

In both cases, installing without removing old material will help reduce space in a room that is already small.

If the old coating was laid out a very long time ago. Minor damage that is not visible to the eye will lead to the destruction of the new tile.

Availability sewer pipes under old tiles. If there are no special hatches, the old tiles must be removed and the layout of the room being finished must be reconsidered.

If the floor level changes significantly, it is also advisable to completely remove the coating. New tiles are laid after leveling the surface. If all the rules are followed, the new coating will delight the owners of the premises for a long time.

During renovation work, we try to simplify some stages, and therefore we ask ourselves: is it possible to put new tiles on the floor and walls on top of the old ones? The approach is very non-standard, opinions vary. Let's try to understand this issue.

This method of installation is used extremely rarely

Feasibility of the operation

In addition to the possibility of gluing tiles onto old tiles, another question arises - why leave the finish from the previous renovation? There is a rational explanation:

There is no need to dismantle the previous cladding, which is labor-intensive and sometimes costly.
The quantity is decreasing construction waste and dust.
There is no need to level the surface, which reduces material consumption.
Preparation time is reduced. This factor is relative, since, while saving on some operations, you have to perform other actions, sometimes no less labor-intensive.

Before making a final decision, consider and reverse side question. If the cladding is laid on old tiles, then you will inevitably encounter the following problems:

Hiding the area. The tiles and mortar already occupy a layer of several centimeters. Additional application of glue and tiles will further reduce the area of the room and raise the floor level.
Defects in old masonry. It is important to check the previous finish for voids and loose parts. Otherwise there is a risk that new cladding will collapse along with them, since the coating will not withstand the additional load.
Tile processing. Before installation old material carefully processed. Such preparation will take no less effort and time than simple dismantling.

When tiling old tiles, many requirements must be met.

To summarize: in general, laying tiles on tiles is possible, it all depends on the specific situation. But if you are worried about at least one problematic point, it is better to abandon the idea.

Preparation

It is very important to properly treat the surface, since the strength of the future coating depends on its quality. To do this, a number of manipulations are carried out:

Removing chips. It is advisable to check all old finishing for the presence of fragile areas and, if serious defects are identified, get rid of them in advance.
Cleaning. A layer of grease and other dirt will inevitably accumulate on the surface of a wall or floor that has been in use for a long time. You definitely need to get rid of this, since laying tiles on a dirty surface simply won’t work. There should be absolutely nothing left that will reduce the quality of adhesion between the coating and the adhesive.
Removing the glaze. The main problem is the glossy surface. If you lay a tile on top of a tile with a smooth, shiny glaze, it will most likely new finish at the same moment it will begin to slide. To prevent this, the coating is cleaned. It is best to use a grinder with a sanding attachment. Be sure to wear glasses and a respirator as the glaze creates a lot of dust and small glass shards. If you do not have the above-mentioned tool, walk along the tiles sandpaper or make frequent notches. The last option is quite unsafe, as it violates the density of the previous masonry.
Degreasing. Glue tiles only to a clean surface. Additionally, the ceramics are primed.

Stages of preparation for cladding

Glue selection

The quality of laying tiles on old tiles largely depends on the mortar used. In this case, it is important to ensure reliable contact between the materials. The adhesion of ceramics and glue is inferior to adhesion to concrete. Therefore, it is important to open the water-absorbing layer of the tiles by removing at least 60% of the old glaze. It is also recommended to use special concrete-contact primer mixtures intended for such work.

Reinforced highly elastic compounds

To reliably fix tiles on the walls, it is important to choose the right glue. For flooring it is permissible to use ordinary mixtures or cement-sand mortar. For walls, dense and at the same time elastic compositions are selected.

It is best to glue tiles using quick-drying solutions. Accelerated drying will prevent the finish from slipping, as it sets to the surface and increases density. Remember that if you glue the material too thick layer, the speed of setting of the glue decreases, and the risks of delamination of the masonry increase.

Rules for performing installation work

Be sure to use a stopper to prevent the cover from slipping. The tiles are laid in several stages. Do not glue too many rows at one time, especially if we are talking about large items.

Let's look at how to properly stick tiles onto tiles:

First, apply a small amount of glue to the old cladding.
Then the mass is leveled with a notched trowel.
Next, the tile is applied and pressed against the mortar.
The position of the element is corrected and the width of the seam is set. Same with the next tile.
After the initial drying of several rows, work on repairing the upper part of the wall continues.
Having covered the entire area, wait until the solution dries well. It will take 1-2 days, if high humidity premises - increase the time to 4. Only after this, start grouting the joints and cleaning the coating.

As you can see, the principle of finishing such a base is no different from the usual technique. Do they do styling? ceramic tiles on top of the old one? Yes, this option is possible, but only if all preparatory measures are followed. In general, it is better to turn to a more traditional method and not take risks.

Hello! We are renovating our bathroom and have encountered a problem. The old tile floor is very durable, even and smooth. But the decor and color do not match the purchased wall tiles at all. Before this, the walls were simply painted, but we easily scraped off the paint. But to shoot down flooring, you will have to work hard with a hammer drill, then re-level the base, and so on. It's long and expensive. We want to put new tiles on top of old ones.

I tried to look for answers on the forums. Some participants argue that this is completely acceptable. Others recommend not saving and solving the problem major repairs. What do you say?

Answer

Good afternoon As practice shows, most homeowners prefer not to carry out dismantling work. In the case of tiles, this can really be avoided and here's why.

Tile as a flooring material consists of thin plates of baked clay mass of high density and strength. The coating is available in a huge variety of sizes, but with two types of surface:

Laying tiles, according to manufacturers' recommendations, should be carried out using contact adhesive on cement, less often - polymer based. Cement-containing dry mixes are produced by absolutely all manufacturers building mixtures(from Kreps to Knauf), since the composition is quite simple, but the quality factor of the material largely depends on the quality of the raw materials. Polymer products belong to a highly specialized series and are produced only by the largest concerns chemical industry(Eurocol, Uzin, Kiilto, etc.)

Tile tiles are most often laid on dry cement mixtures. With their help, you can not only partially level the rough base, but also firmly fix the floor covering on almost any base of sufficient strength (at least 150 MPa) and rigidity.

An old ceramic floor can easily be classified as one of these floors. With one essential condition– a smooth glazed or varnished (enamel) surface has almost zero adhesion coefficient. But first you need to create a so-called adhesion bridge. Or, more simply put, make the top of the tile rough. This is achieved in several ways:

You can use any other primer compositions marked “for non-absorbent surfaces" They even allow you to lay tiles outdoors and are suitable for a variety of difficult substrates, including ceramics, stone, bitumen, asphalt, old glue and much more.

Removing the surface enamel or glazed layer with a grinder with a special attachment for granite and stone. This method is used infrequently due to the formation during operation huge amount dust. However, it allows you to lay a new tile on the old one with the guarantee that not a single element will “fly off” in the future.
By cutting notches on the surface of the coating with any tool - an ax, a grinder with a diamond cup, etc. This method, in combination with priming, is considered quite reliable and has also been time-tested.

Thus, gluing new floor tiles onto old ones is permitted provided there is a rough surface. If the coating is not smooth, you can simply use reinforced tile adhesive.

Before work, be sure to check the floor for:

Next, you need to clean the surface, degrease, treat it with Betonkontakt primer or make notches, followed by removing debris and dust from the floor. After this, apply tile adhesive in accordance with the instructions and lay the ceramics.

If you want to remove the glazed or enamel surface completely, do not forget to thoroughly remove dust and clean the base, degrease and prime after removing the smooth coating. Only after this can the tiles be laid with glue.

When renovating an apartment, a situation often arises when, instead of the old one, tiles need to put in a new one. The work of dismantling old tiles is hard work associated with the need not only to remove the tiles themselves, but also to remove large volumes of construction waste and level the floor or walls. Therefore, the question “is it possible to lay tiles on tiles” arises very often in such cases. Is it possible? Yes, subject to certain conditions.

Inspection of old tiles

To find out whether it is possible to lay a new tile on the old one, it is necessary to examine the strength of its attachment to the base. To do this, the tiles are first inspected to detect cracks, chips, and falling fragments. If the tile appears to be holding tightly, it is tapped with a wooden hammer, and if there is chatter or cracks, the poorly secured tile is chipped off. If most of the tiles do not hold up well, and there are voids underneath them, you will have to dismantle them, level the floor or walls, and only then lay new tiles.

It is also necessary to find out whether the floor level will be higher than the threshold level of the room. Too much thickness of the covering on the walls also does not look aesthetically pleasing, and in this case it is also better to remove the tiles.

Laying tiles on tiles

If the condition of the old coating is satisfactory and the decision is made to lay tiles on tiles, it is necessary to roughen the old tiles, otherwise it will be impossible to achieve good adhesion of the new tiles. You can do this in several ways:

Remove the glossy top layer from the tile;
Make notches on the tiles;
Treat its surface with a special primer.

The first two methods are labor-intensive and involve a lot of dust. The third method requires additional material costs for the purchase of primer.

Removing the top layer, as well as making notches, is done using a grinder. This is done in order to create contact between the tile adhesive and the lower moisture-absorbing layer of the old tile. The top layer of the tile can not be completely removed, but the contact area of the adhesive with the tile should not be less than 60%. The notches are applied at a distance of 1-2 cm from each other.

More modern way giving smooth waterproof surfaces roughness - treating it with a concrete-contact primer. This primer has excellent adhesion to glazed top layer tiles and creates a rough coating on top of it, on which tile adhesive fits perfectly.

Technology of laying tiles on tiles:

Tiles laid on top of old ones can serve faithfully long years, but there are situations when this is not recommended. Laying tiles on tiles is not advisable if:

When tapped, the tile does not collapse, but the sound is inhomogeneous. This indicates the presence of air voids, and tiles laid on top of such a coating will create too much stress on old mortar, causing the tile to fall off along with the old one.
The room, for example a bathroom, has a very small area and poorly aligned walls. In this case, laying tiles on top of old tiles and a thick layer of plaster greatly reduces useful dimensions premises, and it is better to remove the old coating and do the cladding according to all the rules.
The tiles are very old and prone to formation small cracks, chipping, destruction of the top layer. Tiles laid on such a base will not last long, and everything will have to be redone.
Old communications were laid under the old tiles without installation of inspection hatches and access to the pipes. If it is necessary to replace the pipes, you will have to carry out large-scale dismantling work and remove both layers of tiles at once. It is more rational to spend a little more time and money on dismantling and laying new pipes and tiles.
The tiled floor is uneven or has a fairly large slope that needs to be leveled. In this case, it is better to remove not only the tiles, but sometimes also old screed, and repair the floor according to all the rules.
