IN mandatory, the tiles are laid on a prepared base. Its role is played by a floor or wall, which must first be leveled. It should be noted that today there are quite a few methods of leveling, and one of them is laying plywood. Thus topical issue laying tiles on plywood, and to be honest, the technology of this process.
Let's start with the advantages:
- The first is the low cost of such coverage.
- You can also note the speed of installation. Which requires less effort and time.
- The next advantage is the absence of construction waste.
- The plywood cladding itself is quite durable and strong.
But do not forget about the disadvantages:
- First of all, you need to select correct view material, which is sometimes quite difficult. Thus, for work you will need sheets of plywood of at least 2.2 centimeters.
- For rooms with very high level humidity will need to be provided additionally; accordingly, this increases the cost of the coating.
- And the last is a strict ban on
That is why this technology is used quite rarely. Although it may be quite suitable for arranging floors in the kitchen or hallway. In general, in those rooms where it is necessary to carry out repairs as quickly as possible, and preferably, litter as little as possible.
Features of laying tiles
The first question that often arises is whether it is possible to lay tiles on plywood. And all experts answer only yes. Of course, as with any other installation, in in this case there are a number of difficulties. Therefore, we can immediately note that the process of laying tiles on plywood in this way is quite labor-intensive and must be approached responsibly.
It should be taken into account that plywood is divided into moisture-resistant and ordinary plywood, which is not suitable for wet work.
First of all, you will need careful surface preparation. This is largely due to the characteristics of the tile, and in particular the fact that its weight is much greater than that of other types of coating. That is why you should check the surface for strength. In no case can plywood itself have low strength.
Ideal option Of course there will be ones that have moisture-resistant properties and less mobility
In addition, as mentioned earlier, the thickness of the sheets must be at least 22 millimeters.
Each sheet must be securely fastened and pressed to the base. Otherwise, if any deflections or distortions are observed, the coating will last quite a short time.
When laying plywood on joists, it is necessary to ensure a step of no more than 30 centimeters. If the value is higher, redo the design.
And regarding the logs, it should be noted that in this situation the thickness of the sheets should not be less than three centimeters.
Preparing for work
Before starting work, you must carefully prepare, check the presence of all necessary materials and tool.
Also calculate the adhesive mixture and the number of tiles. In the case of tiles, it is necessary to take into account the area of the room, the size of the joints and the size of the tile itself. In addition, the presence of a pattern and method of installation. You can use our website for calculations.
Speaking of the adhesive mixture, its quantity should be calculated based on the consumption indicated on the packaging; you can find out how to select the adhesive mixture and calculate its quantity in a separate article.
Directly for the work you will need the following tools and materials:
- Sanding machine for working with plywood.
- Waterproofing material (mostly film).
- Primer.
- Special glue if necessary.
- Also, for marking, a ruler, pencil and tape measure.
- Self-tapping screws.
- Tile.
- Adhesive mixture for tiles.
- Grout and crosses.
Next, the surface is sanded and cleaned. The tightness of the fit is checked. If necessary, additional fastening with self-tapping screws is provided. There must be strictly no gaps or deflections in the sheets.
Upon completion of the test, the surface must be primed. Typically the primer is applied in several layers (2-3). Each of them must dry completely, which, depending on the type of primer, takes from 5 to 12 hours.
Laying tiles on plywood with your own hands
In this case, it is recommended to use adhesive mixtures, which are characterized by an increased level of elasticity since wood is a movable material. It is in this situation that such a mixture is most optimal, since plywood can be somewhat transformed under the load from the tiles. Moreover, this material does not tolerate moisture and temperature changes well.
Nai the best option will be polyurethane glue, which is often used when laying parquet. This is the mixture that will be most effective.
Another advantage is that within an hour you can walk on such a surface. This is due to the short setting time.
Silane-based mixtures are another good option. This glue is recommended for use in damp rooms, as it sets easily even when exposed to moisture. At the same time, the same moisture is completely removed from the surface.
Thanks to the use of this type of mixture, the tiles will lie perfectly, and the seams will be flexible and elastic, which is very important.
The working process
Having finished with the preparation, you can move directly to the question of how to lay tiles on plywood on the floor. This process is performed using the following technology:
At this point, the installation is completed, and you can admire the results of your labors.
What you need to know about laying tiles on plywood
- In order to be able to lay the tiles on plywood, its thickness must be at least 2.2 cm; it is possible to use several layers, otherwise the coating will not support the weight of the tiles.
- It is recommended to provide additional fixation using self-tapping screws for a better fit of the coating.
- Before laying the tiles on the base, be sure to use a strong primer, which will help ensure the stability of the plywood.
- When working, be sure to use a building level. In addition, it is recommended to start the installation itself from the farthest corner from the door.
- It is necessary to strictly ensure that all seams are completed same size. For this, special ones are used.
- Upon completion of the work, important factor becomes the selection of grout and its implementation, since it is this that has the greatest influence on appearance coverings.
This concludes the question of how to put floor tiles on plywood can be considered closed. By strictly following the instructions and recommendations, you can complete the installation yourself. And for a better understanding of the topic, we recommend that you familiarize yourself with the video materials presented below.
Tiles are laid on plywood on the floor when it is not possible to use other materials to level the rough base. It is important to follow the installation technology, otherwise the coating will not last long. Plywood must be protected from liquids, since this material is highly susceptible to moisture.
In addition, it is necessary to ensure sufficient strength of the rough foundation. This is due to the fact that plywood, even with relatively large thickness the sheet bends. The absence of static material is main reason destruction of the cladding.
It is generally accepted that it is permissible to use only a concrete screed as a rough base for ceramics. However, this is a misconception, since the method of laying tiles on plywood with your own hands also allows you to obtain a coating with a sufficient level of reliability. But for this, the material must be at least 22 mm thick. Otherwise, the coating will not provide sufficient strength. If plywood will be laid on top of the joists, you need to prepare more durable material. For this purpose, sheets with a thickness of at least 30 mm are used.
Plywood is part of the group of wood-based materials and is therefore susceptible to liquids. To avoid the formation of fungus, moisture-resistant sheets should be used in rooms with high humidity levels. If you plan to use plain plywood, you need to ensure reliable moisture insulation.
When choosing this installation method, you should remember that when leveling the rough base you need to use a large number of self-tapping screws The smaller the step between the fastening elements, the higher the level of strength of the coating. When installing plywood, the logs should be spaced at a distance of 30-40 cm. For comparison, the fastening of a natural wood covering is carried out using crossbars, which are located at a distance of 50 cm.
Plywood sheets are laid in 1 or 2 layers. A distance of 1 cm is left between them and the wall. The sheets should be located at a distance of 0.5 cm from each other. Such measures make it possible to compensate for the linear expansion of the material. If all the conditions considered are met, the plywood will last much longer, and the cladding will ceramic tiles will not be damaged.
Features of wood-based materials
Plywood, as well as sheets of similar properties (OSB, chipboard) contain wood in crushed form. It could be wood chips or shavings. The raw materials are bonded and formed into sheets using resins. If you plan to lay tiles on a plywood base, you should consider the following features:
- The use of resins in the production of wood-based materials makes it possible to obtain moisture-resistant products that are characterized by increased strength. However, such plywood has significant disadvantages. A decrease in adhesion is noted. The more resins were used, the worse the adhesion of the rough base and glue. For this reason, the tile will be weakly fixed. In addition, some resins used in plywood contain formaldehyde, which can pose a health hazard.
- Considering that the material contains crushed wood, it is just as easily subject to deformation as solid wood. natural wood. This means that the plywood will swell and dry out when the ambient temperature changes.
Nuances of cladding
Considering that a gap of 3-5 mm is left between the sheets of wood-based material, these leaks should be filled with putty, having previously treated the ends of the plywood with drying oil. When the materials are completely dry, a primer should be applied to the entire surface of the rough base. Moreover, it is recommended to perform the procedure again. After this, you can begin cladding.
Laying tiles on plywood is carried out provided that the rough base is well protected from moisture. Considering that wood-based materials contain resins, due to which there is no need to apply a layer of waterproofing on top of plywood sheets, it is recommended to lay a moisture-resistant coating only on the side of the joist system. Additionally, the plywood must be treated with an antiseptic.
Preparing for work
When choosing tiles take into account color scheme interior of the room. In some cases flooring allocated. For work you will need materials:
- Grouting joints. It is recommended to use epoxy compounds for finishing bathroom tiles. Can be used in other rooms cement mixtures or epoxy-cement.
- Adhesive for tiles on plywood. Standard cement-containing mixtures are not used. This is due to the exposure of plywood to moisture and high temperature, which leads to changes in sheet sizes. It is recommended to carry out the work using special glue. Available varieties: two-component, silicone, mixtures for moving bases, parquet adhesive based on modified silane. With their help, you can not only glue tiles to plywood, but also increase the moisture-proof properties of the coating.
- Waterproofing. It is recommended to use liquid or powder mixtures.
You should know that treating the surface of the subfloor with a primer also helps to increase the moisture resistance of plywood. Before applying this composition, it is recommended to sand the base. To ensure that the heads of the screws that secure the plywood sheets do not interfere, it is necessary to recess them into the surface layer of wood-containing material at the installation stage.
Before you start laying tiles, you must first lay a sickle mesh on the subfloor. Its use improves adhesion. The technology for laying tiles does not change. Glue can be applied on top of the mesh.
Laying tiles on the floor
Correct selection The adhesive composition determines the quality and reliability of the coating. To work you will need tools and materials:
- crosses;
- spatula with teeth;
- containers for water, glue;
- roller
First you need to lay the tiles on the plywood without using glue. This measure will allow you to arrange the products in accordance with the pattern, if one is intended. In addition, preliminary layout will help determine in which areas the material needs to be adjusted. Then an adhesive composition is applied to the rough base.
Special blends, intended for moving coatings, are characterized by a liquid structure. This means that in the process of laying tiles on a plywood floor you will not have to use a rubber hammer, the main function of which is to compact the adhesive after the cladding has been laid. It is recommended to use a heavy roller instead of this tool. It is rolled over the entire surface of the tile. This is enough to compact the adhesive mixture, since polymer-containing materials have a liquid structure. This means that the composition itself will be distributed over the surface.
To properly glue ceramic tiles, you need to determine the size of the seam joints between the products. Too large a distance will lead to gradual destruction of the coating. This is due to the insufficient stability of the base. It is better to place the products as close to each other as possible.
Plywood glue dries quickly, so it is recommended to apply it on small area(for finishing 1 m²). Moreover, you need to clean the surface immediately, because then you will have to put in a lot of effort to clean the tiles. Finishing work can begin from the corner of the room, move along the wall or diagonally. There is another option - installing the trim from the central point of the room.
Final stage
A special feature of the beautiful installation is the grouting of the seam joints. It can be done as follows:
- the grout mixture is prepared, it is recommended to do this in accordance with the manufacturer’s instructions;
- The cladding coating is cleaned of dust and dirt;
- by using rubber spatula apply the mixture, and take a large portion, since this will allow you to fill the smallest leaks between the tiles, and after grouting, the excess will be removed.
Work on finishing the joints of the coating should begin the next day after the installation of ceramic products is completed. If you start grouting right away, this can lead to deformations in the adhesive layer between the tiles and the rough base. However, some types of mixtures dry quickly, allowing you to continue Finishing work within a few hours after the installation of ceramic products is completed. Considering that plywood, even after fixing, is not highly stable, it is recommended to choose fairly reliable, but elastic mixtures.

Having started do-it-yourself repair, it is not always possible to foresee all its nuances. Sometimes this process becomes unpredictable due to various circumstances and presents us with surprises. It happens that sometimes a particular type of work cannot be carried out in strict accordance with the requirements of the technology. And then home handyman you have to think about how to combine 2 materials that are considered incompatible with each other.
Today we will talk about ceramic tiles and plywood. Some will say that it is stupid to even try to lay ceramic floor tiles on a plywood surface, but I would like to note that this is not entirely true and exists real way, which we will consider below. Laying tiles on plywood can be done by both professionals and on our own. Which method to choose is a personal matter for everyone. However, in the second case you can save a lot. Decide for yourself what is more acceptable!
Laying ceramic tiles on plywood: technological features
In what case would this method be most appropriate? Of course, if the house is built of wood, or using technology frame construction. This design option is quite light in weight, and if there is also a wooden floor (high-quality logs), then flooring from boards can be made quite quickly, without incurring large financial and labor costs.
Now about. This material, as a type of finishing, is very widespread. It is used for both walls and floors, indoors for various purposes, starting from the bathroom and ending with the living room. Ideal surface for its installation it is considered, of course, concrete screed. But in the absence of such, laying ceramic tiles on a plywood sheet is also possible. Laying floor tiles on plywood or wall cladding: all this is done using almost the same technology.
Even professionals in this matter take advantage of this opportunity and do not neglect laying tiles on a plywood surface. True, the complexity in this case increases slightly. And the process itself is practically no different from installing tiles on any other type of surface. What is the difference between this method and others? Everything is very simple: preparing the base for laying ceramic tiles.

Nuances of preparing the base
So, let's start with the fact that the plywood base must have a thickness of at least 22 mm, and when it is laid on logs, it increases to 30 mm. This is necessary to give good rigidity to the base; it is this that will ensure the quality of the entire further procedure and will not allow the tile to move and crack.
- To reduce the so-called surface stress, in this case it is a plywood sheet, it must be divided into 4 square parts.
- Only after this can you begin to secure it to the joists or wooden floor. This is done in a checkerboard pattern. A floor made of planks or parquet is also suitable for attaching plywood to it.
- Please note: if the plywood sheet is fastened to joists, then they should have gaps of no more than 40 cm. This is important! This plywood floor will be of high quality.
- And also, when fastening plywood using self-tapping screws, do not skimp on their quantity. Since their more frequent arrangement will make the plywood floor more rigid and help it not to sag.
- And this, in turn, will reduce the degree of possible vibration of the base sheet. If you secure the sheets in this way, then in the future you will not expect surprises in the form of cracked slabs.

When laying a plywood base, it is necessary to control its strictly horizontal position using building level. Only in this way will the plywood floor fully meet the requirements for the surface intended for laying tiles. And if we talk about tools, you may also need:
- screwdriver;
- roulette;
- marker;
- hammer;
- jigsaw;
- putty knife;
- tile cutter
If you have sheets of plywood that are thinner than those recommended above, you can use them, but in 2 layers. When performing this type of base preparation, make sure that the seams of these 2 plywood layers do not coincide with each other.
To give a greater degree of rigidity to such a two-layer plywood base, use adhesive composition, gluing the sheets together, and in addition, the top sheet of plywood must also be fixed using self-tapping screws.
Due to the fact that plywood is susceptible to the effects temperature conditions and humidity, experts recommend not fastening it end to end. It would be most correct to leave small gaps of approximately 0.5 cm between the sheets of plywood.
The distance from the wall to the plywood should be at least 1 cm.
This gap can be filled using polyurethane foam or fix the baseboard.
Before proceeding with the actual installation of floor tiles, the plywood surface must be thoroughly cleaned of dust and other contaminants, and then leveled. For this purpose, a procedure such as grinding is used.
At the moment when you fasten the plywood using self-tapping screws, do not forget that their caps need to be recessed a little into the base, only in this form they will not interfere with the subsequent sanding process.
After finishing sanding, clean the surface again, this time using a vacuum cleaner and a damp sponge. On next stage perform priming of the surface: this procedure will be especially high-quality if you perform it twice. This option will help you provide additional waterproofing and enhance the protection of the wood base.
If you plan to lay ceramic floor tiles in a room with a high degree of humidity, such as a kitchen, bathroom, etc., then it is best to purchase sheets of plywood with moisture resistance characteristics for arranging the base.
Regardless of whether you are finishing the walls with ceramic tiles or the floor, you will need to apply a waterproofing layer, and only then lay out the tiles. For these purposes, you can use a ready-made waterproofing composition. It can be liquid or it can have the qualities of a powder.
Only after the primer and waterproofing layer have completely dried does it become possible to lay ceramic tiles.

Many novice craftsmen are interested in how to glue ceramic tiles to plywood when finishing a kitchen or bathroom in wooden house. Choice suitable composition it is quite difficult to do, since the materials are poorly compatible with each other.
This is exactly what we will talk about in this article.
The main thing
The base composition is usually a two-component polyurethane adhesive made using synthetic substances. The drying process can last from several hours to two days.
The product has a number of advantages that should be mentioned without fail:
- the affordable price of the adhesive composition has a positive effect on the consumer’s budget;
- a high level of elasticity makes it possible to use products for problematic bases;
- the operating temperature range ranges from -55 to +125 degrees, thereby expanding the scope of application;
- good adhesion allows you to reliably connect almost any materials to each other.

Ceramic tiles are already long years is one of the most popular floor coverings for residential and commercial premises. It has many advantages, including attractive appearance, the ability to choose patterns and colors, strength, reliability, durability, and resistance to many types of mechanical loads and impacts. Ceramic tiles can be laid not only in bathrooms, kitchens and corridors, but also in living rooms.
Tiles laid on plywood
Floor tiles vary not only in color and pattern, but also in the material used. Today, such tiles are made from ceramics (familiar to many tile), porcelain tiles (especially durable, but also expensive tiles), vinyl, natural stone.
Before you start renovation work When installing such a floor covering, you must immediately decide on what base it can be laid, what conditions must be observed and how complex the complex of preparatory work is.
Now we will try to answer a question that is very relevant for apartments in old multi-storey buildings, where the base is most often leveled using ordinary plywood sheets. The question is: is it possible to lay a tile covering directly on a layer of plywood?
Tile laying options: which base is suitable?
First, let's decide on what kind of base floor tiles can be laid and what conditions must be met for this. Experts recommend laying floor tiles only on a carefully leveled and solid base. Most often, such work is performed on a concrete floor, but it happens that you have to lay tiles on a plywood base.
- Laying on concrete is considered the best option, since here you can level the surface quite easily cement screed in a relatively small layer. But there are also disadvantages here: the base must be waterproofed and a layer of primer applied. More often than not, it is recommended to build a deck made of adjustable plywood.
- The tiles are laid on the old tile flooring. This option is possible, although not recommended by experts, due to the fact that the load on old tiles may cause it to crack. Consequently, the new flooring will stand on an unstable foundation and will soon be severely damaged.
- You can lay tiles on wooden floor which may be the most various designs, but it’s smarter to do it on plywood. That is, as we see, laying on a plywood base is not only possible, but in some cases it is desirable.

Conditions for laying on a plywood base
So, the tiles can be laid on a plywood base. But for this you need to follow some prerequisites so that the quality of the work performed is high and the coating itself is reliable.
The main problem with laying tiles on plywood is that such flooring is heavy, so the base must be able to support such a load. The thickness of the plywood must be at least 18 millimeters, the sheets must not be fragile or have defects.
The fastening of the sheets under the tiles must be reliable, otherwise vibrations will occur during operation, and in places where there are constant deflections, the tiles will simply begin to crack. As a result, in a couple of years you will have to redo everything again, and it is unlikely that you want to get a similar result.
When laying on plywood, one more thing should be observed: important condition: large sheets It is recommended to divide it into separate fragments, which are best fixed with self-tapping screws. Such fragments can be placed with slight offsets so that the seams are staggered. You should not skimp on self-tapping screws: each sheet should have at least nine pieces, and they must be fastened not only at the edges, but also in the middle of the sheet to ensure proper load distribution.
If you plan to lay tiles on logs, then you must remember that the thickness of one plywood sheet should be from thirty millimeters with a step between logs of forty centimeters. Only such conditions will ensure proper rigidity and strength.
If the floor begins to “walk” during use, the tiles will begin to peel off very quickly.
After the plywood has been laid on the base in the proper way, its surface should be sanded and cleaned of debris, and covered with a special waterproofing compound.

Laying stages
Let's now look at how you can lay tiles using two-component adhesive on a prepared and cleaned base. The modern adhesive composition, created on the basis of polyurethane, eliminates any deformation and cracking.
It is recommended to start laying tiles on a plywood base from the second row, so that you can then trim the edges as accurately as possible and lay the first rows. This coating will look neat and beautiful. This method is suitable for almost any installation option. We begin installing the tiles from the far corner, moving towards the exit of the room.
Each row is checked for evenness using a building level. The glue must first be applied to the floor surface (no more than one square meter), and then onto the back side of the tile using a small notched trowel. The glue layer should be uniform and not very thick.
The tile is pressed against the surface for a few seconds, after which you can begin laying the next one. While the glue has not dried, the position of each tile can be adjusted, but it is best to first apply markings to the floor surface, according to which the installation will be carried out.
Adjacent tiles should be separated from each other using special crosses, which ensure the evenness of the masonry and connecting seams. The tiles can be laid with seams of any thickness, but it is better if they are up to three millimeters in size - this will provide greater aesthetics.
After installation, a day later, the crosses are removed and the joints are filled with grout, the excess of which can be removed with a clean napkin.
