How to lay tiles: lay old tiles, lay wall tiles on the floor, new floor adhesive on the wall. Is it possible to lay tiles on tiles: technology for performing the work Is it possible to lay tiles on old

The article answers numerous questions that arise for those who decide to independently lay tiles during renovation.

Laying tiles yourself: answers to all questions

Ceramic tiles are a common option for finishing walls and floors in the kitchen, bathroom and toilet. This material is practical, durable and easy to maintain.

Installation is a simple process. The main thing is to pay attention to surface preparation and the choice of adhesive mixture.

There are also several subtleties that, having become familiar with them, even a person who knows nothing about repairs can perform fastening of the material.

Is it possible to lay tiles on a wall with old tiles?

Laying work requires careful preparation of the base surface, which is cleaned as much as possible of the old finish. Laying on an old wall covering is always fraught with great risk, since the weight of the tiles and the weak adhesion caused by such “multi-layering” can cause the material to fall off. In exceptional cases, laying tiles on old tiles is possible, but experienced specialists do not give guarantees regarding service life. In other words, it is better to refrain from this finishing option “at your own peril and risk,” especially on the walls.

Primary requirements

When tiling walls, the quality of work primarily depends on how well the base surface is prepared. Special requirements are placed on its evenness.

Why laying tiles on curved walls is undesirable

Ceramic tiles have limited flexural strength per square meter. m., which is why it is better to lay this material on flat walls. In addition, uneven walls significantly increase the consumption of the adhesive mixture.

How to level the surface

After measuring the wall using a level, if irregularities up to 10-15 mm are detected, cement or gypsum mixtures. If the indicators are higher, drywall is used.

Rules for assessing wall evenness

Since high-quality masonry requires Smooth surface, work begins with determining the evenness of the wall.

This can be done using:

• slats or rules;
• plumb line with a load;
• construction bubble level;
• laser level (level).

The most accurate and convenient way– use of a level.

What should be the angle

Particularly difficult is preparing the corners. After preparation and alignment, it should be exactly 90°, and the deviation along the line cannot exceed 1 mm.

Methods for laying on a smooth concrete wall

Laying tiles on a concrete wall has a number of special preparation requirements.

Concrete is characterized by comparatively less adhesiveness than other materials that serve as the basis for cladding. Therefore, to improve the quality of adhesion and roughen the structure, a special type of primer is used, which is called concrete contact.

But, cracks and irregularities can also be on concrete wall. If the differences in unevenness are more than 3 cm, it is necessary to plaster the walls in order to minimize glue consumption. In addition, if you do not plaster a surface with a difference in unevenness of more than 5 cm, there is a possibility that the tile will crumble over time. After this, the wall must be primed again.

There are several basic ways to lay tiles on a wall:

1. Straight. Vertically located tile seams on the same line or with a half offset.
2. Diagonally. This method is used when combining different colors, as well as for creating patterns. The marking is carried out taking into account the angle of inclination of the tiles, which inevitably increases the number of cut tiles, which is economically more costly.
3. With offset. Most difficult option, in which the tiles are laid offset relative to the previous row.

How to lay large tiles yourself

When using large-sized tiles, it is necessary to make the base surface as even as possible, otherwise the work will require a lot of time and more material consumption.

When fastening large tiles, glue with increased adhesion values ​​of 1 MPa is used. The room temperature should be between 20 - 25°.

When working with such material, it is extremely important to distribute the adhesive mixture as thoroughly as possible with a spatula “comb” in order to prevent the formation of air layers under the coating, which reduce adhesion to the base. It is recommended to “comb” the grout on large tiles in one direction, as this makes it easier to remove air from under the material. Laying is carried out immediately after applying the adhesive mixture, when the adhesion force is maximum.

Beginner's Guide

The process of laying ceramics on walls is not the most difficult type repair work, which even “newbies” in repair can easily handle on their own.

How many rows can be laid on the wall at one time?

Provided that the glue is correctly selected and the use of a metal profile fixing the first row, as well as plastic crosses, the number of rows is not limited. Good glue sets in 15-30 minutes. After this time, there is no need to fear that the ranks will creep down.

How to properly lay tiles on the walls in the bathroom: laying corners on the wall

Laying walls at a junction, at a protruding corner, poses difficulties for many inexperienced craftsmen. Most often such places are located in the bathroom - communications are hidden behind them.

There are three main ways to work in these zones:

1. Positioned at an angle of 90° . This is the simplest method in which the elements are placed at an angle of 90° to each other. In this case, one cut remains open and the use of grout is necessary, which makes the results less aesthetically pleasing than with other methods.
2. Trimming edges. The tile sections are ground down with a grinder or with a tile cutter to 45°, after which they are combined with each other.
3. Using Trims. Trims are special plastic profiles with a protruding part in the center, which are placed at the corners and covered with tiles.
4. Using tiles in the shape of a corner. The easiest way. When using it, further installation is carried out from the edge of the corner tile.

How to start laying the first row: rules

Laying the first row - crucial moment, since it is he who is a kind of guideline for all subsequent ones.

When working with the first row on the wall, marks are made along the upper cut of the tile located below all.

Using a level, these marks are connected into a straight line throughout the entire fastening area and secured to it. metallic profile or a rail that will keep the material from sliding to the bottom.

What you need to know to lay tiles evenly on a concrete wall

In order for the ceramics to lie flat on the concrete wall, you need to carefully measure the surface. If there are no pronounced differences, use concrete contact to provide additional roughness. Sometimes plastering is required.

Is it possible to lay tiles from top to bottom?

This method of laying is unacceptable, since there is no possibility of securing the fixing profile and the lower rows will slide under the weight of the upper ones.

How to quickly glue tiles

In such a matter as repairs, it is necessary to reduce haste to a minimum. But if 1-2 tiles fall off, you can use a special type of quick-drying glue “liquid nails”.

How to fix tiles on a wall without glue: alternative options

There is no alternative to the adhesive mixture when laying tiles. All methods, in addition to the main one, are a compromise and can be used in exceptional cases.

Some experts fasten the tiles with self-tapping screws if they can hide the caps behind decorative elements or furniture.

Rules for laying tiles on a clay wall: how to lay and glue

Laying tiles on clay walls is an extremely complex and time-consuming process, since clay is less solid foundation than hardened tile adhesive with the material.

Therefore, it is necessary to first cover the walls with moisture-resistant plasterboard, minimizing the gaps between it and the wall, or attach the tiles to a metal profile. Next, installation is carried out in the appropriate way, depending on the chosen option.

Laying tiles is an integral part of renovation work in the kitchen, bathroom or toilet. Any homeowner can do it themselves, having first familiarized themselves with the rules and intricacies of this process. This will reduce costs and make repairs more economical. In addition, in this case the owner will be confident that the work was done conscientiously.

Useful video

All owners of apartments and houses have a desire to make repairs efficiently and quickly and at the same time avoid difficulties. A lot of them want to know how to lay tiles on tiles. This finishing method is quite viable; if a number of conditions are met, the new layer of ceramics will hold firmly and for a long time.

What can be avoided when laying tiles over old ones

Tiles on the floor and walls in the bathroom when carrying out overhaul causes real shock. Especially if the room had complex waterproofing or the finishing was created during the construction of the house.

Laying tiles on tiles will allow you to avoid a number of fairly large-scale difficulties and can look like a rational solution. Inconveniences may be:

1. When removing old coating, the formation of a huge amount of debris is inevitable. It will need to be stored, removed and transported by special transport. If you do it yourself by laying tiles on old ones, you can get rid of a whole range of hassles.
2. Bathroom or toilet equipment may be installed in such a way that dismantling the old coating will damage the sanitaryware. If there is no financial opportunity to replace the equipment, laying tiles on tiles looks extremely attractive. Those who have never installed or connected a bathtub and toilet will see even more advantages in this option.
3. Removing old ceramics may require completely redoing the floors or walls. For example, thin reinforced ties laid on a raised floor or plywood will probably also have to be dismantled, since they will be damaged. Remodeling the base is much more difficult than laying tiles over old ceramics. A similar problem arises in the bathroom, where waterproofing is done using the coating method. The layer of polymer or mastic will have to be completely removed and the protection against water restored. By laying ceramics on old tiles, you can avoid solving complex problems.
4. Sometimes it is not possible to free adjacent rooms or protect them from dust. When dismantling an old coating, not only a lot of debris is generated, but also inevitable clouds of fine concrete dust that penetrate everywhere. If you lay ceramics directly on the tiles on the floor, you can carry out all the work very carefully.
5. When removing the old coating with inevitable damage to the screed, you will have to remove it, which will significantly lower the floor level. Therefore, installing new tiles on old tiles is a rational solution.

Everyone evaluates the acceptability of laying ceramics on an existing coating from their own perspective. But the fact remains: many people find this method of finishing attractive. Especially considering that the building new screed will require procurement Supplies, time and qualifications to carry out the work, the cost of removing construction waste is added to the financial expenses. It's no wonder that a lot of people want to know how to lay tile on tile.

Preparing the base for laying tiles on tiles

There are situations when it is not recommended to start laying on old tiles; the glued layer will not last even a year. Before deciding to carry out any work, you should carefully weigh the pros and cons, and also make sure that the conditions for applying new ceramics will ensure its long service life.

Before making a decision, you need to make sure whether the new tile can be laid on the old one. To do this, a number of checks are carried out:

1. The old coating must be durable and monolithic. You can check this criterion using a small hammer, tapping each tile in different places. If a dull sound is heard at all points, the old ceramics fits well and evenly. In cases where the blows are loud in many places, we do not glue new ceramics, the existing coating is applied poorly, there are voids under the finish. If there are few points where the hammer sounds loudly, it is worth considering the option of removing unreliable elements.
2. The evenness of the surface is carefully checked. Builders do not suffer from perfectionism. In houses, especially older buildings, there are often cases when the difference in height along the surface of the floor or wall is several tens of millimeters. It is difficult to compensate for such a difference using an adhesive composition; in addition, there is no guarantee that the new coating elements will be firmly fixed.
3. Each tile on the floor is assessed - cracked and moving ones are found. If there are only a few of them, you can put new ceramics on top of the old ones with a minimum of additional work.

The base on which the tiles are placed also plays an important role. With the floor, everything is relatively simple: when assessing the possibility of laying new ceramics, the issue of raising the floor level is considered.

Preparing the surface of old tiles

The main thing that needs to be achieved before laying tiles over the old one is that the surface has sufficient roughness for adhesion glue mixture. Used in several ways:

1. Removing gloss from tiles. This operation is done using grinders or drills with attached grinding wheels. The work is very monotonous and hard. A huge amount of dust is generated, so eye and respiratory protection is required. It is recommended to work in pairs. The second performer will hold the mouth of the vacuum cleaner in the area where ceramic dust is emitted. When removing gloss from tiles, you need to wear safety glasses and special clothing, since not only dust will fly from the tool, but also small pieces of a glassy substance.
2. Creating notches. The operation is performed using a grinder. It is impossible to use a hammer, chisel or perforator: the surface of the tile is durable, and a strong blow will split the ceramics. The use of protective glasses, masks and protective clothing is mandatory. Many flying sharp pieces of glassy mass are formed.
3. Drilling. By using a glass drill, you can create a base suitable for glue adhesion with a minimum of effort and debris. To do this, recesses are made using a mesh across the entire surface where the new tiles will be laid. The drilling depth should be small - just go through the gloss layer on old ceramics. The only drawback of this method is the large amount of time and effort that will be required to complete the work.

All of the above work creates a lot of noise, dirt, and requires large quantities time. Their only advantage is that they are cheap. Modern means will help avoid dust problems and guarantee good results.

Before gluing the tiles, the old ones are processed using Betonkontakt class mixtures. A composition with ordinary coarse sand is relatively cheap, while a composition with quartz is more expensive, but the resulting surface better holds the adhesive composition applied to it.

The use of special mixtures to increase adhesion is carried out in accordance with the manufacturer's instructions. It is not recommended to deviate from the recipe, aging time, or complete drying. This type of processing takes place without dirt, unnecessary noise, and quickly. But before applying the composition to the surface of the floor or wall, final preparation of the base is required.

Final preparation of the old base

Before applying tile adhesive or special agents to increase adhesion, the area of ​​the old finish must be completely prepared.

Held:

• removal of cracked, moving elements of the coating, followed by cleaning and sealing the depression with cement-containing putty, the requirement is that the surface after treatment must be smooth, forming a single level with the old ceramics;
• inspection of the condition of the grout, if there are cracks, signs of coloring, mold - the composition is removed;
• thorough cleaning and drying of the entire surface for finishing using detergents;
• complete disinfection, degreasing using alcohol-containing products or solvents;
• anti-mold and .

Carrying out this work is a mandatory stage.

The base under the new tiles must be protected and have no areas of mechanical weakening .

How to lay tiles on tiles

Laying of new ceramics is carried out according to standard rules. Conventional adhesives are used and applied with a notched trowel. It is better to lay the covering elements from the doors. In bathrooms and toilets, the direction is chosen so that the last rows are located under the plumbing. This will ensure their minimal visibility and the trimmed parts will not disturb appearance coverings.

The main feature of laying new ceramics over old ones is that the drying time of the adhesive composition increases significantly. The reason is the low absorbency of the surface of the existing finish. But there is no need to be upset about this. When laying a new coating over an old one, you can work slower to some extent and ignore drafts. The main thing is that the room temperature is maintained above 15 degrees.

The degree of increase in drying time is significant. Ceramics laid over old ceramics should not be walked on or subjected to stress for 3-4 days, as opposed to the standard 12 hours for coatings on concrete. Afterwards, the joints are grouted, followed by cleaning the surface.

The period of complete drying increases from 5 days to at least three weeks. During this time, you should not place furniture, bathtubs, plumbing fixtures or other heavy objects on ceramics laid on top of old ones. If you carefully prepare, clean the surface and follow the recommendations for drying time - laid on existing basis the coating will last a long time and will not create problems.

In the process of carrying out repair work with your own hands, you have to deal with many difficult questions, the correct answers to which will determine the quality and service life of the new finish. One such question is, can you lay tile on tile? Let's consider whether it is possible to use the old tile as a basis for a new coating or whether it is better to dismantle it to avoid possible problems.

Features of preparation various types surfaces. How to rub seams. Criteria for choosing tile coverings and laying patterns for the floor.

How to remove old grout from tile joints

Quite often you have to deal with a situation where the condition of the old tile is quite satisfactory, but in order to use it as the basis for a new coating, it is necessary to replace the grout for the joints. It is quite possible to carry out this procedure, however, it requires attention and time. Let's look at how to remove grout from tile joints correctly.

In order to remove old grout, there is a special tool called a “grout remover.” It can be used to remove grout mechanically. By itself, it is a blade with a comfortable handle, but as an alternative, you can use a regular knife.

The blade of a knife or embroiderer must be passed on both sides at an angle and straight. When doing this, you need to be careful not to chip the edges of the tiles. It is worth noting that this cannot be done quickly “by hand”, so you can use a drill with a thin drill bit or an electric chisel.

Important! If, in the process of removing the old grout, the tiles also begin to crumble, it is better to abandon the idea of ​​laying another layer on top, even if there is new grout.

How to remove old grout from tile joints if it is silicone

Silicone grout also requires dismantling and replacement, especially if the room has not been provided with high-quality ventilation. Very often you have to deal with the fact that the seams are affected by mold, which is almost impossible to remove. Therefore, before laying new tiles over old tiles, you need to take care of the hygiene of the joints.

Removal silicone sealant carried out using a sharp knife or a special scraper. After this, additional cleaning is carried out using a vacuum cleaner.

Helpful advice! There are special products that allow you to remove silicone faster and with less effort. Such compositions are applied using a mounting gun, after which it is necessary to wait at least 24 hours. Then the seams are wiped with a rag or paper.

Is it possible to lay tiles on tiles on the floor: features of the work

Floor coverings, unlike wall coverings, are not subject to gravity. Therefore, in a sense, installation is easier. But in this case, another difficulty arises - the new coating will regularly be subject to serious loads.

Before gluing tiles to the floor, you need to carry out an equally thorough check of each element of the lower layer. To do this, you can use the same hammer for tapping, but you can try another approach: an object with a flat base (a box works well), you need to smoothly drag it across the surface, carefully observing that not a single tile falls even a few millimeters. It can be difficult to do this in a small bathroom or toilet, but for indoor bigger size this is a very effective way.

In general, all the recommendations provided in the previous section are also relevant when working with floors. It is only advisable to give preference mineral compositions. Thus, the surface will be provided with greater elasticity, which will allow it to withstand heavy loads and temperature changes.

Helpful advice! Before you put it floor tiles on top of an old ceramic coating, you don’t have to carry out such intensive preparatory work, as in the case of the wall surface. But it’s still worth moistening the base before you start applying glue, as this will have a positive effect on adhesion.

Is it possible to make a self-leveling floor on old tiles?

As a basis for a new coating, you can also use a self-leveling floor, which is installed directly on the surface of the old tile. As in all previous cases, mandatory procedure– thorough check of the quality of fastening of the lower layer. All loosely fitting elements must be dismantled.

It is also worth paying attention to the fact that in cases where we are talking about working with a glossy surface, the top layer of coating is removed to ensure the necessary level of adhesion between the solution and the tile. Filling and further work are carried out according to the standard algorithm.

Helpful advice! Laying a new layer of tile does not require a thick layer of self-leveling floor. Its thickness should not exceed 5 mm. The main thing is to distribute the composition evenly over the entire surface.

Taking into account the opinion of experts, we can say that installing a self-leveling floor on top of tiles is possible only in extreme cases. In this case, the area of ​​the room should be small, and the requirements for the operational characteristics of the surface should be minimal.

Is it possible to lay tiles on tiles outdoors?

Very interest Ask that may arise - is it possible to lay a new layer paving slabs on top of the old one. Of course, such a procedure is often unjustified, but still, in some cases, this technology is resorted to in the process of arrangement garden paths, terraces and summer areas.

As in the case of tiles laid on old flooring inside the house, the main criterion is the quality of fastening of the lower layer. You can check it using a pry bar or a strong knife. Using such tools, you should try to remove one of the elements.

Important! If the tile was able to be moved using a knife, but this required serious physical effort, then such a coating can be used as a base. If the tile comes off easily, this may later cause deformation of the top layer.

A new cushion is poured on top of the old layer of tiles, which should consist of three layers - loose soil, gravel, sand. In this case, compaction of each layer must be carried out separately. On top, according to standard technology, a new layer of paving slabs is laid.

Thus, the answer to the question of whether it is possible to lay tiles on tiles on the floor in the bathroom or even on the walls is rather in the affirmative. Of course, during the work process you will have to follow many rules and recommendations, and the end result can almost always be unpredictable, but in principle, this is quite possible.

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 amount of construction waste and dust is reduced.
• There is no need to level the surface, which reduces material consumption.
• Preparation time is reduced. This factor is relative, since, 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 the 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 finishes for 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 tile on top of tile with a smooth, shiny glaze, chances are the new finish will start to peel off immediately. 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 securely fasten tiles on 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 to a layer that is too thick, the speed of setting of the glue decreases, and the risk of delamination of the masonry increases.

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:

1. First, apply a small amount of glue to the old cladding.
2. Then the mass is leveled with a notched trowel.
3. Next, the tile is applied and pressed against the mortar.
4. The position of the element is corrected and the width of the seam is set. Same with the next tile.
5. After the initial drying of several rows, work on repairing the upper part of the wall continues.
6. Having covered the entire area, wait until the solution dries well. This will take 1-2 days, if the room humidity is high, 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. Is it possible to lay ceramic tiles over old ones? Yes, this option is possible, but only if all preparatory measures are followed. In general, it is better to turn to more traditional method and don't take risks.

A material for interior decoration, the demand for which there is no doubt, is decorative tiles made from ceramic materials. With its help, the design of a bathroom, kitchen, or hallway will be not only practical, but also beautiful.

Laying high-quality tile floors is 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 coating the walls with liquid waterproofing. The time spent on repairs will increase, and the cost estimate will become significantly higher. To avoid this, you can put ceramic tiles on 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:

1. Careful inspection of the surface of the walls and floor.
2. It is necessary to show maximum attention, pay attention to every crack and other defects.
3. A thorough inspection of the seams between the tiles and their condition is also important.
4. 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.

Using a building level, check the spatial arrangement of walls and floors. In case of severe deviations, the previous coating must be removed and then the coating must be leveled. special composition. 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:

1. Removing the top glossy layer. If it is absent, nothing will interfere with the clutch.
2. If it is difficult to completely remove the glazed coating, you can apply notches to the previously laid tiles.
3. 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 due to a large amount of dust during work, the third method is perfect.

It, unlike the first two, will require certain investments, since a good primer composition It's 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 off, then wipe the surface thoroughly.

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 all the preparatory activities are left behind, new tiles are laid. Further stages of installation are carried out according to the traditional scheme. It is important to remember that when installing this way, the adhesive will take longer to dry, 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 tile will prevent the two layers of coating from holding together, and the tile will simply fall off after a certain time.

Small room dimensions or uneven surface.

When small area room, 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.
