Can you put tiles on a plywood floor? Laying ceramic tiles on plywood. Material selection and base preparation

18885 0

The most optimal foundation for laying ceramic tiles, is concrete surface or a base made of sand-cement screed. But unfortunately, this condition is not always feasible, so in houses old building, or, conversely, in buildings made according to modern technologies using SIP panels, floors and sometimes walls are made of wood or wood-containing materials.

With such laying, it is impossible to use the "warm floor" systems

So this factor puts inexperienced home craftsmen into confusion when carrying out repairs in their home, because at first glance, gluing ceramic tiles on materials containing wood is extremely unreasonable, due to the too obvious difference in their physical properties and characteristics. So how can it be, is it possible to lay tiles on plywood or other wood-containing materials, in the absence of the possibility of a traditional base, or refuse to use tiles when decorating a bathroom or kitchen?

A distinctive feature of wood-based materials

Materials containing in their composition, wood in the form of shavings or chips and various resins as a binder, subject to certain technological requirements, with success can be applied as the basis under facing of a surface with ceramics. The most common is plywood, particle boards(chipboard) and oriented strand board (OSB).

Before applying the adhesive composition to plywood, it is recommended to learn more about its composition.

To obtain a high-quality result and prevent premature destruction of the surface to be coated, it is necessary to lay ceramic tiles on these materials, taking into account two important factors:

1. Since the main component of plywood, chipboard and OSB is wood, these materials will have the same properties that are inherent in source material. In particular, under the influence excess moisture, the wood swells and, conversely, in the absence of moisture, it dries out. That is, the surface to be coated lacks dynamic stability, and the constant movement of the base can adversely affect the condition of the coating and even lead to its destruction.
2. The resin contained in the plywood as a binder worsens the adhesive characteristics of the material, and therefore it is not possible to glue tiles to plywood in the traditional way.

Facing wood-containing surfaces with ceramic tiles differs from laying on concrete and sand-cement screed bases and has its own subtleties and features.

Advantages and disadvantages of using plywood as a base for cladding

For a complete understanding of the situation, and an idea of ​​the problems that may be encountered when using wood-containing materials for ceramic finishing, we will outline the main advantages and weak sides this decision.

Advantages

• high speed of work;
• no need to carry out labor-intensive and costly work on the construction of a concrete or sand-cement base;
• relatively small mass of the structure, allows cladding in wooden structures or buildings with a foundation that is not designed for additional load;
• the ability to glue tiles even in wet conditions bathroom or kitchen.

Flaws

• the thickness of the plywood used under the base must be at least 22 mm;
• the need to carry out measures for additional waterproofing of the premises, in case of its operation in wet conditions;
• the impossibility of installing a “warm” floor system if the cladding is carried out on plywood, chipboard or OSB.

It is noteworthy that the quality of plywood depends less on the veneer, and more on the glue with which it is glued.

Material selection and base preparation

Before laying tiles on plywood, you need to go through two stages preliminary work, namely:

1. Selection, calculation of the required quantity, purchase and delivery the right materials to the place of work.
2. Inspection of the surface for cladding and its preparation for the installation of ceramics.

The main thing to pay attention to when choosing a material is correct selection adhesive for tile installation.

The main criterion that should be followed in this case should be the property of the adhesive mixture to adapt to the possible movement of the surface to be coated. Therefore, the composition of such an adhesive necessarily contains components with high elasticity: microfiber, fiberglass, silicone and other polymer additives.

You can, of course, glue ceramic tiles with alternative compounds used by some craftsmen, such as liquid nails, liquid glass, or generally a complex mixture of varnish and foam chips treated with acetone. But given the importance and responsibility of the work carried out, as well as the high cost facing material, it is better not to take risks and give preference to specialized compounds intended for use on wood containing bases. A good option would be to use a two-component polyurethane adhesive or an adhesive mixture that has a silane in its composition.

The calculation of the required amount of tiles is made, taking into account the following factors:

• surface area to be coated;
• geometric dimensions of elements;
• type of installation;
• the presence of a pattern that requires a certain adjustment of the elements.

The amount of glue is taken based on the rate of its consumption per square meter, this value is indicated in the instructions for use of the adhesive.

When examining the base, you need to make sure that the plywood is thick enough and securely fixed to the floor structures to prevent shifts and deflections. If there are no comments, you can proceed directly to the preparation of the foundation. Plywood sheets are carefully sanded, the seams between them are sealed, and after cleaning from dust and debris, they are treated with antiseptic compounds. Then the plywood is impregnated with waterproofing mixtures, this should be done even if moisture-resistant plywood is used.

Priming plywood increases the resistance of wood to destructive impact moisture

It is necessary to prime plywood in two layers at intervals of several hours for complete drying of the primer composition. If the finishing takes place in a room with high humidity, for example, in the bathroom, then you need to additionally protect the base from getting water on it, using a waterproofing film device. To improve the adhesive properties and better adhesion of ceramics to the surface, it will be useful to fix it on plywood before the primer, reinforcing the serpyanka mesh.

Laying technology

After the base is completely ready, you can start laying ceramic tiles. It is better to do this from the corner of the room by laying it there whole element without cuts. The glue is evenly and evenly distributed over the back surface of the fragment and the surface to be lined with a notched trowel. Then the ceramic tile must be pressed to the surface and fixed for a while for better adhesion.

Tap the elements with a rubber mallet in this case there is no need, since the adhesive used for laying ceramics containing materials on wood has a sufficiently liquid consistency, which allows you to securely glue the fragment without applying additional efforts to tap the tiles with a mallet.

Actually, in the future, the process of laying tiles on plywood is no different from installing tiles on traditional bases made of concrete or sand-cement screed and consists of the installation of ceramics itself, processing and jointing.

Vladislav asked a question:

Good afternoon forum members! A very important question for us! Started a renovation in a private country house, but the estimate is very limited for a number of reasons. The house has a plywood partition between the kitchen and the bathroom. They wanted to overlay it with tiles, now it is pasted over with self-adhesive. In theory, this “building” should be replaced with drywall, we were told that it is impossible to glue tiles on plywood. On the other hand, the market now does not offer any materials for repairs, and we thought - maybe there is still some new super glue for tiles on plywood ?! Thanks in advance for your reply!

Tiler answer:

Hello! Indeed, glue for laying tiles on plywood exists. But the problem is not the presence of special glue, the question here is the durability of the coating base. The fact is that any wood base (chipboard, plywood, OSB and others) is easily deformed under physical and temperature effects, and these materials are also very hygroscopic (absorb moisture from the air). Resins that bind wood chips and sawdust in chipboard, etc. materials, somewhat reduce hygroscopicity, but still do not protect them from moisture, especially in such places in a residential building as a bath and kitchen. With an increase in air humidity, your partition will swell, and with a decrease, it will dry out, and soon the tile will simply fall off the wall. Therefore, the question "how to glue ceramic tiles to a plywood base" has the wrong wording. Here it is more important to find out exactly how it is worth gluing ceramics to plywood and similar materials that have a wood component.

First of all, make sure that the base for future cladding is sufficiently even. If somewhere there are bulges or, on the contrary, fossae, individual sheets there are discrepancies in the joint, then they must be tightened, the heads of the screws and nails should be sunk into the surface of the plywood boards. When updating the installation, make sure that the joints of the plates are on the supports.

Before laying ceramics, it is necessary to prime the surface. This will reduce the adhesion (hygroscopicity) of the base to a minimum. You can apply the primer with a roller or brush, but ideally it is better to repeat this operation at least two times.

Now it’s actually worth talking about how to choose the right tile adhesive. Just at this stage, the question becomes relevant: how exactly to glue the tiles to plywood. Main Feature adhesive mixtures for laying tiles is the presence in the composition of highly elastic components that allow you to hold ceramic tiles on such a relatively mobile material as plywood. Such laying glue is quite liquid, during the installation process it is not necessary to tap each element, the mixture itself is distributed over the surface. The adhesive solution should contain polymer modifiers (silane, silicone, fiberglass, microfiber, and others), or take universal wood glue, although this option can hardly be called a budget one.

There are a number of non-standard ways to lay tiles on plywood. For example:

• liquid nails - glue must be applied along the perimeter of the part to be glued in a solid line, fix the tile at the time of gluing, grout with epoxy-based compounds;
• silicone sealant- the connection is very reliable, but not budgetary, the grout will be the same silicone, only transparent;
• polystyrene foam with acetone - pour in a plastic bowl foam plastic not large quantity acetone, apply the resulting mixture either on the tile or on the surface with an ordinary spoon, the most budget option!
• polyurethane foam- apply a small amount of foam on the back side of the tile and quickly press firmly against the surface, there will be no foam expansion;
• acrylic glue - it is necessary to apply a continuous layer, the option is more economical than liquid nails.

In general, your case is quite simple. Use our tips for laying tiles on the partition. But keep in mind that if you are going to glue the tiles on the floor in the bathroom, then either exclude the installation of a warm floor or still replace the plywood with another base.

Technology of sticking ceramic tiles on plywood

modern building private homes today uses revolutionary technology that simplifies self building process, but at the same time, the erected houses are not inferior in comfort to traditional buildings built using traditional methods. At the same time, building materials are used in construction, which were rarely used before, or were used for certain works. For example, plywood. Usually it was used for filing ceilings, making doors and wall cladding. frame houses. But today this building material has been used as a leveling element, like drywall, which simplifies the finishing processes. In addition, manufacturers offer modified moisture-resistant plywood, which made it possible to use it in wet rooms. Hence the question from many private homeowners, is it possible to lay tiles on plywood.

The answer to the question posed is yes, because at present, in addition to the most modified plywood, more than quality materials in the form of adhesives and primers. It is they who provide the possibility of laying tiles on plywood.

It is necessary to immediately make a reservation that not only walls, but also the floor base can be leveled with plywood. That is, it turns out that when the task is set, how to lay tiles on plywood, it is necessary to understand that both the surfaces of the walls and the floor will be facing.

Process Nuances

There are several nuances of the finishing process, on which the quality of the final result depends.

• For this, a plywood sheet with a thickness of at least 22 mm should be used (the larger this size, the better). It's all about the loads to which it will be subjected. This is especially true for floor cladding.
• Plywood is laid on the floor in a run-up with an offset to the floor of the sheet. it perfect option. Although the offset may be smaller. This is done for the sole purpose of evenly distributing the load over the entire area.
• If the floor base is plywood laid on logs, then the inter-lag distance must be strictly adhered to. It must be strictly 40 cm, no more, no less. In this case, the fastening of plywood sheets to the logs (boards) must be carried out not with self-tapping screws, but with anchors.
• Tiles are laid on plywood with special adhesives. glue on concrete base won't fit here. Such glue in its composition has some components that increase its elasticity and strength. For example, fiber.
• It is necessary to note several positions regarding tile adhesive. Most often, craftsmen use a two-component composition, intended for gluing expensive wood parquet, which will be laid on a plank floor. Such adhesive material is somewhat reminiscent of epoxy resin. And it consists of polyurethane resin and hardener. Hence, in principle, both its elasticity and its strength after drying.

Attention! Someone might decide that two-component tile adhesive can be replaced with epoxy. Do not do this, the result will be negative, and you will be greatly disappointed.

What else is different glue for tiles on plywood.

• There are varieties of universal type in the model line. They glue tiles on plywood, on concrete, on drywall, on other wood-based board materials.
• Adhesive layer always stable, and during the laying process does not lose its elasticity.
• Manufacturers note that such an adhesive composition perfectly adheres to wooden surfaces.
• It is a non-combustible material, moisture resistant and does not react to temperature changes.
• The service life is the same as that of the tile itself.
• One package is enough to lay floor tiles on plywood with an area of ​​10-12 m².
• The adhesive composition hardens, depending on the ambient temperature, within 0.5-1.6 hours. That is, after this time, for example, it will already be possible to walk on the tiled floor.

So, the question of how to glue ceramic tiles to plywood is illuminated, you can proceed to the cladding process.

How to properly tile plywood

In principle, the basic cladding process itself is no different from the standard technology. That is, it is necessary to accurately calculate the required amount of tiles based on the laying structure (in order, with an offset or diagonally). Select a laying structure.

The main requirement for the process of preparing a plywood base. That is, before gluing the tiles to plywood, you need to bring the wooden base to required level adhesion. And although two-component adhesive compositions can stick tiles without a primer, experts advise not to avoid these costs, especially since they are scanty. It is better to apply the primer in two layers. But before that, you need to deal with the gaps.

Whether you like it or not, when laying plywood on the floor or walls, there will be a gap between the sheets, which must be closed. Therefore, the joints of the sheets are processed either with a primer or drying oil. After drying, it is necessary to seal the cracks with a putty mortar. And after it dries, the entire plywood surface will have to be primed.

Markup must also be included in the preparatory stage. Laying tiles on plywood has a specific approach to the process itself. That is, it is necessary to start facing from the center, moving to the sides. For example, if it comes to how to glue ceramic tiles on plywood that is installed on the wall, then you need to measure the width of the wall from the bottom near the floor and determine the middle of this size. This will be the starting point in the lining process.

After that, the number of solid tiles that will be laid vertically is calculated. Of course, the size and number of stitches are taken into account. Usually the bottom first row will be assembled from cut tiles. Therefore, at its upper level, a mark is made in the form of a horizontal line along which solid cladding elements will be assembled. It is along this line that the rail is installed or metallic profile under drywall. This is a kind of support that will support the first rows of trim. After completion of the whole process, the shelf is dismantled. By the way, it is attached to the plywood surface with self-tapping screws.

Now, as usual, the tiles are being laid, but you only need to start from the middle, which was indicated in advance. It is better if the glue is applied in a thin layer both on the tile and on the plywood, leveling it with a notched trowel.

Attention! The grooves on the tile and on the plywood sheet must be mutually perpendicular. This will increase the strength of the joint and create an even layer of flexible tile adhesive.

As for the question of how to lay tiles on plywood that has been laid on the floor, here you will have to determine the center of the room. To do this, you need to connect the opposite corners of the room. That is, draw two diagonals, the intersection of which is the same necessary center. Then you need to divide the floor area into four sections. This is easy to do - you need to connect the middle of the opposite walls to each other, the lines will pass through the center of the floor base.

Experts recommend first laying out one row of tiles "dry". Thus, you can understand how much ceramic tiles will have to be cut. Usually, they try to make the styling so that the trimmed element is located on one side, and it is better that the one that is less visible will be hidden under the bath or shower, sink or other plumbing fixture or piece of furniture.

And the laying process itself can be done in different ways. For example, each of the four sections can be tiled separately, tiles can be laid in a circle relative to the center, plywood flooring can be closed, starting from the far wall relative to front door. That is, it is necessary to choose an option that would be convenient for the manufacturer of the work.

Before gluing tiles to plywood, you need to apply tile adhesive to the tile itself, and then to the floor. As in the case of wall cladding, it is necessary to distribute the adhesive composition with a notched trowel. The grooves are applied perpendicular to each other. The tile is laid on the floor, slightly pressed and leveled by hand or with a rubber mallet.

Attention! Regardless of how you can glue the tiles on plywood, meaning on the walls or on the floor, you must not let go of the level. For evenness of the masonry, each element is checked individually and in combination with neighboring tiles.

Grout

So, the last stage is the grouting of ceramics. The process is the simplest, which requires the trowel itself (ready or dry) and a rubber spatula. The material is applied with a tool along the joints of the tiles with slight pressure so that the grout fits snugly into the gap. The spatula must be held relative to the tiled surface from above at a right angle.

Pay attention to some points that relate to the quality of the grout.

• It can be applied over ceramic cladding only after complete drying of the latter.
• In the process of laying the tile itself, crosses are used, which determine the thickness of the seam. So, if in the gap will accumulate a large number of glue, care must be taken that it does not take up much space. It is necessary to leave a place for grouting. Therefore, excess glue must be removed at the stage of facing, when it has not yet dried up and turned into stone.
• After the fugue has completely dried, it must be removed with a clean cloth or sponge. No brushes or other rough materials.

Conclusion on the topic

So, the question posed, whether it is possible to stick ceramic tiles on plywood, is fully lit. There are no problems and there should not be, because this process, in principle, is standard with some nuances that allow for high-quality cladding with a guarantee for long-term operation. And they help modern materials, especially for adhesive composition, to stick on which the tile is a 100% guarantee High Quality.

How to lay tiles on plywood with your own hands beautifully and for a long time.

• 1 Preparing for tiling
• 2 Laying tiles
• 3 Grouting

Plywood is wonderful building material when it comes to sheathing large flat surfaces. At the same time, ceramic tiles to this day remain a good finishing material that does not lose its popularity. The only question is how to combine them. Traditionally, tiles are laid on concrete screed. Both the screed and the tile are not subject to deformation, which cannot be said about the wooden and plywood surfaces. And therefore the question of how to lay tiles on plywood remains relevant.

Ceramic tiles are laid on plywood using elastic adhesives

Currently, many experts have already tested the method of laying tiles on plywood using special elastic adhesives. This method is not suitable only when it is supposed to equip underfloor heating. Warm floors can only be laid in the traditional way - on the screed. In other cases, with proper observance technical parameters, laying tiles on plywood is quite acceptable.

Preparing for laying tiles

In order for the tile to lay flat and not peel off, plywood laid in two layers should be used as a base. The recommended minimum plywood thickness is 2.2 - 2.8 cm. It will be better if it is plywood glued in two layers - to increase the overall strength of the structure. Also, the plywood must be very tightly fixed to the base in order to minimize deformation.

The next step is preparing the base for the tile. Plywood should be sanded and cleaned. The surface under the tile must be perfectly flat. A primer is applied on a flat smooth surface in two layers. After applying each coat of primer, the surface must dry for five hours. If it is necessary to lay tiles in the bathroom, the plywood should be treated with any suitable waterproofing solution before applying the primer.

Laying tiles

Laying tiles should begin with the second row of tiles. The first row can be cut to right size and put last. It is recommended to start laying tiles from the far wall of the room. The horizontal position of the tile installation should be constantly checked with a level. For a while, until the glue has set, the tile can be adjusted until the desired result is achieved. Between the tiles, you can lay out crosses for precise alignment of the seams. The size of the joints usually varies between 2 - 3 mm, but in rooms with high humidity or temperature fluctuations, the size of the joints can be increased to 5 mm.

The adhesive solution dries fairly quickly, within 2-4 hours, so it should be prepared in small portions.

You can stir the glue with a special mixer for greater homogeneity of the adhesive mass. Laying tiles should also be done on small area at the same time - within 1 sq.m. The adhesive applied to the surface of the tiles and plywood will set in 15-20 minutes. Therefore, all manipulations for installing and fitting a tile section should be laid within this time period.

Adhesive solutions for ceramic tiles or porcelain stoneware should be used as adhesives. But this glue should be designed to work with problematic surfaces - drywall, plywood. The selection of glue should be taken with all responsibility. Otherwise, the result of the whole work will be unsatisfactory. When purchasing glue, carefully read the instructions. It should indicate that this type of adhesive is suitable for working with your type of tile and plywood surface.

In addition to traditional adhesives for ceramic tiles, it is possible to use special two-component polyurethane adhesives.

In this case, you can even do without a primer. But waterproofing plywood still needs to be processed.

After the glue has completely dried, grout is applied to the seams between the tiles.

After the tiles are completely laid out, the adhesive should be allowed a few days to set. Despite the fact that the glue dries after 30 minutes, you should not rush. It is better to wait 3-5 days until completely dry. After that, using a rubber spatula, a special grout is easily rubbed into the seams between the tiles. Excess grout can be removed after 20-30 minutes by wiping the tiles with a rag.

The question of how to lay ceramic tiles on plywood turned out to be not so difficult. Following simple rules, you can cope with this task, even without special training.

Laying tiles on wooden floor and plywood; how to lay tiles on chipboard and fiberboard

The need to use ceramic materials for cladding wooden surfaces occurs infrequently. However, when designing some premises or decisions design projects such a need may arise. Laying tiles on wooden floor- the case is quite complicated, and if possible it is recommended to avoid this. The size of a wooden board depends on the humidity of the air, and this may cause damage. facing tiles. Therefore, the use of plywood, chipboard or fiberboard is much more convenient and easier. Such a coating is less susceptible to deformation as a result of changes in air humidity.

Tiles on a wooden floor: how to stick tiles on plywood?

The quality of the installation of ceramics on wooden base depends on the quality of the preparatory work. First of all, it is necessary to carefully examine the base and determine a plan for further work. Tiles on a wooden floor are not glued if the floor is made of wooden planks creaks, flexes, there are protruding nails, or there are signs of rotting wood. If the wood floors are painted oil paint or varnished, then first of all you need to remove all this. Most effective method- it is mechanical, that is, the use grinder or drills with special nozzle. Swinging boards strengthen, sink nail heads, after that it is better to make a flooring from plywood. Tiles are laid on plywood after the latter has been impregnated with primer solutions.

If the floors are concrete, it is recommended to lay a layer waterproofing material from expanded polyethylene. Moisture-resistant drywall sheets are laid on top, which must be attached to the base. Next, you should put logs, multilayer plywood or chipboard and attach them with self-tapping screws. To make the base more rigid, you can lay drywall sheets in two layers so that the seams do not match. Before laying tiles on a wooden floor, the joists must be leveled horizontally very accurately. The gaps between the wall and the rough flooring are best filled with mounting foam.

Next, the resulting coating must be treated with a special impregnation or a layer of latex is applied, and a paint grid is placed on top. The coating must dry well. After that, it is necessary to make a screed from a mixture of water, coarse sand and liquid glass.

Laying tiles on chipboard and fiberboard: tile adhesive on plywood and wood

Laying tiles on plywood starts from the center of the room, so that all trimmings are subsequently hidden under furniture or in corners far from view. for sticker ceramic products use tile adhesive according to the base material. It is important to be careful about the choice of adhesive before gluing tiles to chipboard, since there are adhesives for both chipboard or GVL, and for GKL. You will need tools: a spatula with teeth, dividing crosses, a level, rubber mallet, abrasive for stripping cuts, tile cutter. Laying of the facing material is carried out on an adhesive containing cement in its composition. Since the adhesive dries quickly, you need to lay the tiles as accurately as possible or make adjustments within 5-10 minutes.

Is it necessary to remove the chipboard from the floor before laying the tiles?

When we start to make inquiries about whether it is possible to lay tiles on chipboard in a bathroom or kitchen, most advisers give a negative answer. This is partly true, since the particle board is malleable to bending, and also strongly absorbs vibration from appliances. And the most good reason decisions are not in favor of chipboard - its hygroscopicity. And just the last statement is not relevant today - you can find moisture-resistant chipboard on sale.

Therefore, under certain conditions, it is possible to lay tiles on this material. So, the slabs should not lie on the logs, but on a flat concrete screed - we remember the ease of bending the material. And do not forget about vibration: in rooms where tiles were laid on chipboard, washing machines and dryers should not be placed. If we are talking about mounting on the wall, then it is better to immediately replace the chipboard with hl.

Tiled tiles: how to stick on fiberboard?

Fiberboard for tiles - not the best a good option. The material strongly absorbs moisture, and warps from it. And in tile adhesive enough moisture. In addition, fiberboard bends easily and transmits vibration - just like chipboard. But if the plates are in good condition and laid on a concrete screed, then you can think about how and with what to glue the ceramic tiles to the fiberboard.

The base slabs are covered with waterproofing, and then covered with a dry screed and leveled. From above everything is covered GVL sheets and covered with a special primer. After completing all the work, any adhesive can be used to install the tiles. If you want to lay porcelain stoneware directly on the hardboard, then you need to choose an adhesive that does not contain water.

How big is the role of the base when installing floor tiles?

Anyone who knows more than theoretically how to lay tiles on a floor will tell you that a well-prepared subfloor is half the battle. After all, even slight differences in the level of the floor can lead at least to difficulties in installing tiles, and as a maximum - to a reduction in its service life. Therefore, before laying the tiles, we walk along the floor with the building level.

If any deviations are found, then we will definitely eliminate them. wooden or plywood base corrected by setting the log to the level and tightening the boards or plywood with self-tapping screws. Concrete floors are leveled with a fresh screed, dry or wet. In this case, the tile sticker will have to be postponed until the base is completely dry - from several days to a week, depending on the type and quality of the screed.

How to lay tiles on plywood: what conditions must be observed?

Ceramic tiles on plywood will fit well if you remember the following:

• The thickness of the plywood must be at least 22 mm.
• If the plywood lies on the logs, then the distance between them should be no more than 30 cm. The sheets themselves in this case should be 30 mm thick.
• The plywood must be firmly fixed to cement screed or lags, which are pre-aligned with the building level.
• The seams between the sheets must be puttied, and the surface itself must be treated with moisture-proof impregnation.
• Tile adhesive is better to take on a polyurethane basis.
• Underfloor heating cannot be installed on a plywood base.

What should be done before laying tiles on a wooden floor in a house?

Before laying tiles on a wooden floor, it must be properly prepared. First of all, we remove all the boards and carry out an audit of the log under them. We replace the rotten ones, fix the loose ones, and then with the help of building level check the horizontal lag. We treat everything with an antiseptic composition. Next, we inspect the boards, replace rotten and cracked ones.

After installing the floorboards in place, remove the old paintwork- This is done with a grinder. Before laying tiles on a wooden floor, we treat it with an antiseptic composition, and after drying - with a latex composition or warm drying oil. Next - a layer of waterproofing, installation of a reinforcing mesh and pouring the screed. After the latter has dried, you can start gluing the tiles.

What adhesive is used to mount tiles to wood or plywood?

As a rule, it is easy to find a special tile adhesive for wooden bases on sale. But a simple cement adhesive can also be adapted for these purposes. It is necessary to knead it according to the instructions, and then add plasticizers to the composition - 10 - 15% of total mass. However, such wood tile adhesive is prepared in small portions, as it hardens very quickly. And one more nuance - the solution turns out to be thick, and it is better to stir it construction mixer or a drill with a special nozzle. Only in this way will it be possible to achieve uniformity of the composition.

How to make a screed for tiles on a wooden floor?

Laying ceramic tiles on a wooden floor can be carried out immediately on the boards, but it is better to make a good screed - it will extend the life of the flooring. Moisture-proof impregnation is applied to the pre-prepared floor boards, and then it is laid metal grid and is attracted by self-tapping screws. Then we prepare such a solution: 2 parts of sand and liquid glass + 1 part of water. We apply the mixture to the floor and wait for it to dry completely. After that, you can start mixing the adhesive and laying the tiles on the wooden floor.

Modern building technology constantly evolving, which allows the consumer to enjoy a huge number of possibilities for the use of conservative materials. In this regard, the question of whether it is possible to lay tiles on plywood receives not just a positive, but a detailed answer.

Today you can veneer anything, the surfaces are:

• wood;
• brick;
• concrete.

The first option is quite often interesting for beginners. You can answer positively to the above question for the reason that plywood has recently taken a strong position and is used not only for sheathing ceilings and walls, but also as a floor insulation.

Plywood is chosen by consumers due to many circumstances. This material is suitable for facing surfaces that have an impressive area. Although it is possible to lay tiles on plywood, a number of nuances should be observed. For device warm floors this approach is not relevant, because a concrete screed is required.

Choice of plywood

The tile is a rather heavy material, so it is necessary to choose the right plywood sheet, which will have the appropriate density and thickness. It is one thing to purchase such a base for the ceiling and walls, and another for the floor. The instruction in this case recommends purchasing material whose thickness is 28 mm or more.

The problem may lie not in the moment of laying, but in the consequences, when insufficient sheet thickness leads to deformations. There is not much to say about the material itself. It should be noted only that it is environmentally friendly. Plywood can be waterproof, in this case we are talking about its veneered variety, which is not inferior to clay bricks.

Adhesive selection

When answering the question of whether it is possible to lay on plywood, you must decide which glue to choose. Some experts recommend preferring the right type of solution, while others advise buying universal option for wood. The main feature of such compositions is that they allow the finish to adapt to the movement of the base. Among their ingredients, highly elastic components should be distinguished, namely:

• fiberglass;
• microfiber;
• silane;
• silicone.

However, this list is not complete, because there are other polymer modifiers. Once you have decided whether to put floor tiles on plywood, you should also learn about some other nuances. They lie in the fact that the adhesive for mounting ceramics on wood should be quite liquid, which eliminates the need for tapping on the surface of the finish after installation. The mixture should spread over the surface on its own.

Among non-standard solutions should be highlighted:

• liquid glass;
• liquid Nails;
• varnish NC.

In the latter case, we are talking about a composition to which foam chips treated with acetone are added. However, all these methods do not allow you to get a 100% guarantee of reliable fastening, so it is better to use specialized mixtures.

Additional preparation of plywood

Due to the fact that it is almost impossible to lay on clean, smooth plywood, care must be taken in preparation. For this, the surface should be given higher adhesive properties. To begin with, it is treated with an antiseptic, after which it is applied. This is true even for moisture-resistant sheets. Then, to improve adhesion with the coating, a sickle mesh is fixed on the surface.

Plywood needs to be primed several times. This will not only improve the quality of adhesion, but also provide additional protection material from moisture. Since you already know whether it is possible to lay tiles on plywood, in the next step you can proceed to installation work according to the standard scheme. When facing walls, at the first stage, a support rail is installed so that the material does not slide down.

An important point that must be taken into account when laying tiles and installing plywood itself is that the material will change in linear dimensions when exposed to external environment. For this reason, it is necessary to leave small gaps between the plates, as well as around the perimeter of the room. This will compensate for the movement of the sheets. In order to avoid voids, they can be filled with mounting foam.

Conducting training

Now you know if you can lay tiles on plywood. However, when carrying out such work, it is important to pay Special attention preparation. At the same time, it is important to bring the surface of the wood into perfect smoothness. In order to achieve perfect results, you can screw a few more screws into the material. The main condition here is the requirement that the screw heads are tightly recessed.

Before starting work, it is necessary to prepare a certain set of tools and materials, among them:

• Sander;
• elastic adhesive;
• roulette;
• waterproofing;
• building level;
• hammer with a plastic nozzle;
• Bulgarian;
• grouting solution.

Carrying out waterproofing

Many home craftsmen are wondering if it is possible to lay tiles on plywood. Even if you do not have relevant experience in carrying out such work, then you know that such work can be carried out. At the next stage, the technology provides for waterproofing. This step is necessary for the reason that wood, under the influence of moisture and temperature differences, rots and deforms. Even during the installation of panels, waterproofing can be laid under them, which is mastic or polyethylene.

Before laying tiles, plywood must be coated with a primer in several layers, using mastic for this. For complete absorption and drying, this composition will take 5 hours. With this processing, the above question is no longer worth it.

Masonry

The glue dries pretty quickly, so do not rush to knead the entire volume of the solution at once. The mixture is laid evenly on the surface. After that, you can lay the first tile. You need to start from the corner where the whole product will be. Ceramics are mounted with some pressure on its surface. In order not to deform the tile, it is necessary to tap on the corners and on the central part with a plastic hammer.

Laying tiles on plywood is accompanied by adjusting its position for some time, until the glue completely hardens. Once you are done with the first row, you can proceed to the second. Crosses that are installed between the tiles will help to adhere to a certain size of the seams. The average seam should not be more than 3 mm, however, sometimes tiles are laid with seams up to 7 mm, which is true for those rooms whose conditions differ in temperature differences. Before laying tiles on plywood, you should become more familiar with the technology. It provides for the creation of a flat surface with the help of cladding. In this case, the building level should be used.

For reference

Even a novice master should know whether it is possible to lay tiles on plywood. This question should be answered in the affirmative. However, before starting work, you need to familiarize yourself with some of the nuances. Among them, it should be highlighted that the adhesive may contain hardeners. In this case, the manipulations should be carried out fairly quickly, otherwise the glue will quickly grab, and you will not have time to align the products horizontally.

Conclusion

It is also important to remember about the features of the choice of plywood. You should not take thin sheets in the hope of saving money. good foundation can only be obtained with a 25 mm canvas. Now you know whether it is possible to glue tiles on plywood, but it should be remembered that such a base, even if it is moisture resistant, can deform over time under the influence of moisture. Therefore, it is recommended to use additional funds waterproofing.

Modern a wide range of tiles made of tiles allows you to use it not only in the decoration of bathrooms and kitchens, but also in other rooms. Those who are going to make repairs in the apartment are often interested in whether it is possible to lay tiles on plywood, because sometimes there is no other way to make a tiled floor for a variety of reasons. Despite the seeming incompatibility of these materials, it is possible to lay tiles on plywood. Following the recommendations will help to make a smooth, durable floor that will last for many years.

Plywood quickly absorbs moisture, so it must be impregnated with sealant before laying the tiles.

Alternative to screed

Plywood can be a great replacement for leveling screed when it is not possible to pour it. For example, veneer material is sure to come in handy if you do not want to dismantle a wooden floor and decide to put tiles on it. In this case, plywood will act as a kind of screed. You can also lay tiles on plywood, which will be laid directly on the logs, however, in this case, certain conditions must be met so that the coating lies on the veneer, almost like on concrete. You understand very well that ceramics is a rather heavy material, and therefore a durable surface must withstand it.

Requirements

The strength characteristics of plywood directly depend on the number of layers of veneer, and the more there are, the thicker the sheet. Building material for tiles must have the following data:

1. Thickness plywood sheet cannot be less than 22 mm.
2. The veneer must be of high quality. This condition does not require the absence of knots on the plywood, but the sheets must be firmly glued together. Stratification is not allowed.
3. Plywood boards must be moisture resistant. It is worth adding to this that the material of the FBA and BV brands is not suitable for the base under the tile, since it is absolutely unable to resist dampness. In any case, plywood of any grade must be treated with coating compositions before laying. This is especially true for products of the FSF brand, which can become a source of formaldehyde emission into the atmosphere.

Perhaps some clarification needs to be made regarding the thickness of the base under the tile. Perhaps some will decide that instead of a thick sheet, several thinner ones can be used, but this is not recommended, because a stack of plywood panels will not provide sufficient rigidity to the base, since there are no 2 absolutely identical sheets in nature. This means that between them in one place or another there will definitely be gaps, due to which the floor will be imperceptible, but it will certainly spring, which will lead to cracking of the tiled floor.

Additional measures

A large sheet can also spring, since there are no absolutely flat surfaces. In addition, various deformations of the plywood or the layer under it during operation can contribute to this. Therefore, plywood sheets must be cut into smaller fragments. Naturally, they must correspond in size to the lag step.

The thickness of the plywood should also depend on the space between the lathing bars.

To avoid distortions, the surface of the plywood must be leveled - especially at the joints.

There is no point in doing a step less than 30 cm, but it should not exceed 50 cm either. 30 mm sheets are laid on the bars spaced at such a distance.

Now about how to prepare a hard plywood base. In order for the tiles on plywood to be “comfortable” (it does not peel off or crack), it is necessary:

• treat the veneer with moisture-repellent compounds;
• fasten veneer sheets with as many self-tapping screws as possible, which should be screwed into the wooden base not only around the perimeter and in the center, but also, if possible, along the sheet area;
• make joints not on the same line (it is better if the plywood is staggered);
• clean and sand the surface of the base;
• primer twice.

After that, the tiles on the plywood will stick much better, because the double primer layer will provide good adhesion for the adhesive. It remains to be advised not to rush to apply the next layer of primer. They can be processed only after the previous coating has completely dried. As a rule, this drying process of each layer lasts 5-6 hours.

Tools and materials

This time is enough to check how much fixtures, tools and equipment are prepared for laying tiles on plywood. expendable materials. For work you will need:

• 2-component adhesive based on polyurethane (it provides strength and elasticity of the connection, as well as additional waterproofing);
• grout for finishing seams;
• crosses so that the gap between the tiles on the plywood is the same:
• the starting rail along which the 1st row will be laid out;
• notched trowel for applying glue;
• soft spatula for grouting;
• tile cutter;
• level.

It would seem that it can no longer be used, but it is impossible to guarantee a uniform application of glue over the entire surface of the base. Using the level, you can check the horizontal laying of a whole row or 1st tile and correct its position relative to others.

Tiles on plywood begin to be laid from the corner farthest from the entrance to the room. Theoretically, it is possible that a room can have ideal proportions and only whole tiles will be used to finish its floor, but in practice, geometric flaws are inherent in the vast majority of rooms. In addition, it is impossible to ensure that the floors are covered with only whole products, so the laying is carried out from a row in which there will be no fragments. It should be noted that the laying of fragments near the walls should be carried out only after finishing work with uncut slabs.
