Is it possible to lay tiles on plywood. Elastic adhesive for tiles on plywood: why is it needed and how to apply Glue gypsum tiles on plywood

Tiling to plywood has become popular. Laying tiles on the floor is not difficult, so plywood tiles in the bathroom are in demand. This technology is used in the arrangement of:

• Interior partitions;
• Stan;
• Paul;
• Ceiling.

The smooth surface of the plywood provides a high-quality, dirt-free installation of ceramic tiles. However, in terms of their texture and properties, these two materials have different compatibility. Therefore, in order to properly lay tiles on plywood, you need to thoroughly study the features of this technology, clearly follow the instructions and the scheme of sequential actions for performing these works.

Advantages and disadvantages of new building technologies

Unlike traditional way laying on cement screed, laying ceramic tiles on plywood sheets, has a number of its qualitative advantages and certain disadvantages.

Tiles on plywood have positive aspects:

• A significant reduction in the load on the floor, which is especially important for the arrangement of modern frame wooden houses;
• Obtaining a cladding with reliable strength characteristics and a fairly high service life;
• Obtaining an additional layer of waterproofing through the use of a special adhesive composition, which is very important for the arrangement of premises with high humidity, which include kitchens, bathrooms, corridors.

As for the negative factors, they focus on the fact that:

• The minimum thickness of plywood that can be used to work with tiles or ceramics must be at least 22 mm;
• Additionally, in wet rooms, reinforced waterproofing should be carried out to maintain wooden structures Houses;
• The underfloor heating system is absolutely incompatible with the arrangement of plywood on it for further cladding with ceramics or tiles.

Features of the preparatory stage

Laying ceramic elements on plywood sheets has its own special moments of installation and specific pitfalls. Since ceramics and tiles are heavy, the choice and preparation of the plywood base must be approached very responsibly.

1. Plywood for arranging walls should have optimal thickness 28 mm, for the floor, when laying on logs, at least 30 mm. Its structure must be strong and not fragile.
2. All plywood structures must be securely fastened with self-tapping screws. Parts of the products during installation must fit snugly against each other, since the gaps between them are unacceptable. This is done so that in the future during operation there will be no slightest deflections that will lead to lagging, peeling and cracking of the tiles.
3. Step between lags, with further laying floor covering, should be about 30 cm to ensure uniform distribution load on each ceramic element.
4. The number of tiles required for installation must be purchased, given:

• Room area;
• The size of one tile;
• Laying method;
• Feature of the drawing;
• Cutting waste.

Tools and materials

Provide quality work a set will help you install tiles on plywood necessary materials and tools in the form:

• Machines for grinding plywood sheets;
• Special adhesive with elastic properties;
• Polyethylene film for arranging waterproofing;
• Priming composition;
• Self-tapping screws for wood;
• notched trowel;
• Pencil for marking;
• Building level;
• Roulettes;
• Special plastic crosses;
• Rulers;
• Grouts of the required shade;
• Special glue.

The main stages of installation

When starting work on laying plywood, it is necessary to check the thickness of the plywood layer, sand its surface, and clean it from dirt and dust.

1. Depending on the installation destination facing material, it is necessary to carefully fasten the plywood to the base, taking into account its snug fit and the absence of gaps.
2. The plywood is then primed in two layers. The time interval after applying each layer should be at least 5 hours to allow the previous one to dry well.
3. When arranging bathrooms, after priming, the plywood sheet should be overlapped on top with a dense plastic wrap to create an additional waterproofing layer.
4. To work on fixing the tiles, adhesive compositions of a special action are used. In addition to their main purpose, they additionally protect plywood from all kinds of linear transformations, moisture ingress and temperature fluctuations. Two-component polyurethane adhesive and adhesive compositions based on a modified silane are recognized as the best for this work.
5. After all preparatory work arranging the base of the floor, proceed to the main laying of ceramic tiles. Start it from the opposite corner of the front door.
6. Laying facing tiles for wall decoration has a slight difference. Here, this material begins to be laid from the second row from the floor. So that the tile does not slide down during work under the influence of its weight, they nail under its lower level wooden lath. So she will hold the entire structure until the cladding is completely dry, after which the first row is laid.
7. The adhesive must be applied evenly evenly, both on the tile and on the floor surface. For this operation, a notched trowel is used.
8. After applying the adhesive, the tile is pressed against the main surface by hand and held in this position for several minutes to allow the adhesive to harden.
9. It is necessary to constantly control the thickness of the application of the adhesive layer, using building level.
10. To control the width of the seams between facing tiles, plastic crosses are used. They control the size of the seam during operation, which can be in the range from 1 to 3 mm.
11. After laying the entire tile, the tile joints are treated with grout, the remains of which are removed from working surface with a damp cloth.

Conclusion

Today frame technology construction, where ceramic tiles for cladding are laid on plywood, is a very popular and optimally acceptable option for arranging wooden houses. Plywood is recognized as an excellent building material, while ceramics and tiles are excellent finishes.

Modern building technology today allow you to combine these incompatible materials to create any design solution. After all, ceramic tiles, replacing any wooden surface, brings its special originality to the cozy comfort of the room and creates excellent conditions for living.

Ceramic tiles are very easy to use, have excellent aesthetic and strength qualities, but at the same time make high demands on the base on which they fit. It is easiest to lay tiles on concrete, but what if the apartment has wooden floors or partitions? Is it possible to lay tiles on plywood if you choose this material for leveling the base?

Pros and cons of using a plywood base

Before you figure out how ceramic tiles are laid on plywood, you need to figure out: why can't it just be laid on a wooden floor? The answer is simple: physical characteristics wood and ceramic tiles are too different, and such an undertaking will not lead to anything good.

Tiling requires an absolutely fixed base. Otherwise, the tile will collapse or begin to “walk”, cracks will go along the seams. Wood, on the other hand, changes its geometric dimensions under the influence of temperature and humidity. Therefore, to combine these materials, a lot of preparatory work is required, during which an intermediate layer is formed, leveling the differences between tiles and wood.

To prepare a quality foundation, you can apply various ways and materials. But it has a number of undeniable advantages:

1. This is the most fast way: no need to wait for a long time, as, for example, when a cement or self-levelling screed dries.
2. When laying plywood on the floor, much less dust and debris is generated than with other methods.
3. The weight of the structure under construction is negligible, so the load on the logs or wooden floors will increase insignificantly.
4. The method is quite simple, does not require specific skills or materials. At the same time, it will provide a foundation High Quality with the required characteristics.

Naturally, there are also disadvantages:

1. Plywood is not compatible with underfloor heating.
2. Quality will matter a lot waterproofing works especially in rooms with high humidity. This may result in additional costs.

For laying on the floor, you will need thick plywood, at least 22 mm. It is preferable (and for a bathroom or kitchen it is a must) that it is also moisture resistant. This will also affect the final cost of repairs.

Foundation preparation

Plywood can be laid on draft boards floor, and right on the logs.

For laying directly on the logs, you will need thicker plywood with a thickness of at least 30 mm, the optimal distance between the logs is 300 mm.

More often sheet material lay on top of the floor boards, observing the following recommendations:

• Carefully examine the wooden floors. You can not leave defective or damaged elements: after laying the tiles, access to them will be closed.
• The boards must be cleaned of paint and impregnated with an antiseptic solution.
• A gap of 1 cm thick is left between the surface of the wooden floor and the wall along the perimeter to compensate for possible deformation of the wood. Subsequently, it is closed mounting foam or covered with a plinth.
• Good waterproofing is a must. As you know, the stone "attracts" water, and this will negatively affect the service life. wooden base. Therefore, it is necessary to protect it: you can soak the boards with hot drying oil or latex, use other materials.

In order to make the plywood more rigid, it is recommended to cut each sheet into at least 4 pieces and fasten each piece separately.

• Before installing plywood, you should outline the height of the future base. To do this, draw a line on the wall using a level. You can use beacons, but this is less convenient.

It is better to fasten plywood in a combined way: the sheets are first planted on glue, and then additionally fixed with self-tapping screws. The adhesive layer will not only provide secure fastening, but also smooth out the unevenness of the old floor.

• The thickness of the seam between the elements should be 1–2 mm. With such insurance, the plywood surface will not swell.

Often used laying in two layers of thinner plywood. In this case, the sheets are shifted relative to each other so that the joints do not match. The layers are glued together and fixed with self-tapping screws.

• The heads of the self-tapping screws should be slightly recessed into the plywood so that they do not interfere with the grinding of the base.
• Grinding is performed with a special machine in three directions: along, across and obliquely.

• Using a vacuum cleaner and a damp cloth, the plywood base is thoroughly cleaned of dust and debris.
• Plywood is primed in at least two layers. After applying each of them, you should wait at least five hours for the primer to dry.
• From above, plywood must be covered with a layer of waterproofing. It can be a film laid on walls or other materials.

Laying tiles

Laying floor tiles on plywood is not much different from mounting on a concrete base. The main difference will be in the adhesive used. For use silicone-based adhesives or two-component polyurethane formulations. They remain elastic after drying, which allows you to compensate for possible fluctuations in the base. Also, such adhesives will provide additional waterproofing due to the components that make up their composition.

USEFUL INFORMATION: How to tile a wooden floor in a bathroom

Modern market finishing materials offers a wide range of flooring options. Most often, tiles and plywood protrude into them, which raises the question: is it possible to glue tiles on plywood?

As for flooring specialists, the technology that explains how to glue tile on plywood is relatively new. For a long time, tile materials have been laid directly on the concrete floor - they fit together perfectly and form an excellent hitch. Therefore, the question is whether it is possible to glue ceramic tiles on plywood becomes reasonable and you are faced with the task of deciding on the technology.

Even in this article, we will have to figure out what glue to glue the tiles to plywood in order to ensure excellent adhesion and a durable result of laying the flooring.

Note! If you intend to equip a system of underfloor heating in your house, then you should refuse to work with plywood, since the installation of this equipment is carried out exclusively on top of concrete screed and involves the use of materials resistant to moisture or temperature.

Preparatory stage of work

On the preparatory stage you must take care to pick necessary tools and materials, as well as provide a good foundation for laying.

The list of required includes:

• tile;
• primer;
• plywood;
• level;
• mixer;
• glue;
• building level;
• rags;
• grout.

The first thing you have to do is prepare the foundation for work. Make sure the floor is level and free from dirt and dust. To clean the surface of the base, you can use not only chemicals, but also Appliances to achieve high quality results. A vacuum cleaner is also suitable for removing dust, but in order to cope with dirt, you will definitely have to use special detergents. Before gluing the tiles, make sure that the floor surface is perfectly level.

After that, you can do the installation of plywood on the base. Its sheets must first be glued together in order to obtain double strength. As a result, laying will be done on a hard and very hard surface.

Note! In the process of installing plywood sheets, it is very important to make really high-quality fasteners. You can use self-tapping screws, which should be placed in increments of 20 cm.

At the final stage of the preparatory work, the floor surface is finalized. To do this, you need to apply a special primer. It is better if you apply several layers of this composition. Let the surface dry a little before applying each new layer. Full term drying of the primer is about five hours.

Laying technology

Before installing tiles on the floor, you need to lay waterproofing material, and the installation of the tile itself should start from the second row. The first strip must be left untouched, since it is provided for the subsequent installation of tiles already with undercut dimensions.

Start laying the material should be from the far corner of the room. During the installation process, do not forget to monitor the horizontalness of the surface, using a water-type building level for this. The laying result can be adjusted until the adhesive composition on which the tile sits has completely hardened.

To ensure even tile joints, you can use special devices. For such purposes, corners or crosses are suitable. As a result, you will get seams with identical location geometry. The approximate distance in this case will be two to three millimeters. IN rare cases this figure can be increased to five millimeters. The adhesive composition is best applied to the surface in small quantities, as it dries fairly quickly.

A device such as a mixer will allow you to stir the adhesive composition to a homogeneous state. The area for applying glue to plywood is 1 m². It is this area that is the most comfortable so that you have time to produce high-quality styling and adjust the result until the glue completely hardens and dries.

If you don’t know how to glue tiles on plywood to the floor, the answer is simple - with a specialized adhesive designed to work with ceramic tiles. You should not save on the purchase of this material, it is best to give preference to high-quality global manufacturers with famous name products that have already proven themselves. Only in this way will you achieve reliable and durable adhesion of the two surfaces.

Note! Each glue comes with its own instructions, which can be completely different. Before you start using it, be sure to read the recommendations indicated in it.

In some cases, a specialized two-component adhesive based on polyurethane is used. It is able to provide such high-quality adhesion of materials that there is no need to apply a primer.

Carrying out final work

At the final stage of work on laying tiles on plywood, grouting is carried out, thanks to which the floor takes on a neat and beautiful appearance.

Note! The grouting process should not be started immediately after the installation is completed. The adhesive must dry completely to provide the desired fixing effect. This will take several days.

Some instructions claim that the adhesive immediately seizes the surfaces, but it is better to play it safe once again so as not to spoil the results of your work. This does not mean at all that you should not trust the manufacturer's recommendations, however, it should be borne in mind that the glue is placed between two dense materials that do not allow moisture and air to pass through, and this increases the drying time. It is enough to wait three to five days to be sure.

The material used is a special grout, which must be rubbed into the seams located between the tiles. armed rubber spatula, you can easily cope with this task. Such a tool can be purchased at any hardware store.

In the process of work, you may notice excess material that remains on the tile. They are removed with a soft cloth. It is highly undesirable to use any hard material for this, because it can cause damage to the surface. The cloth must be moistened before use. And after processing the surface, you need to give time to dry.

There is a wide range of grouts on the market, which can be dry or need to be diluted with water. Never use to remove grout residue chemicals because they can provoke a chemical reaction.

An important problem that must be solved when carrying out repairs is the selection of optimal building materials. Incorrectly selected components can further lead to the fact that the repair will not be durable enough, problems will arise that are invisible at first glance. When laying tiles on plywood, it is very important to choose the right adhesive. This is even more important than, as an example, the quality of the wood used. The market offers a rich variety of options, from which it is sometimes difficult to choose. Consider the most popular types of adhesives, namely, elastic adhesive for tiles on plywood.

Glue Features

Elastic adhesive is called two-component polyurethane.

It got its name due to the fact that it comes with two main components:

• special hardener;
• polyurethane resin.

They are mixed, after which a very elastic mixture with outstanding adhesive properties comes out. Mixing two-component tile adhesive on plywood is carried out using a mixer or using a drill with a specialized mixing nozzle.

They must be mixed right before use, they must be used up about half an hour to an hour after mixing.

On the packaging, they periodically write that the mixture dries for about half an hour, but it is better to wait much longer, up to three or four days, to be sure. The question of whether it is possible to glue tiles on plywood does not even arise when this specialized adhesive is used. But why is he?

Why is this glue

There are reasons that motivate the use of the described adhesive when laying ceramics. Wood and ceramics have different properties, as a result they are able to change dimensions relative to each other. This is facilitated by jumps in humidity and ambient temperature. If the adhesive composition does not adapt to this, it will turn out that noticeable damage may occur, or, even worse, imperceptible, which does not appear immediately, but some time later. It is necessary to consider the type of adhesives at the stage of initial selection of materials in order to understand how to glue ceramic tiles on plywood in the most optimal way.

The wooden coating is strongly deformed under heavy loads; without the elastic properties of the adhesive, the tile can peel off.

It is important to take into account other features of the compositions, in particular, the tree tends to delaminate, the composition should not penetrate too far into the material so as not to create additional problems. Before gluing tiles to plywood, it is important to understand this point.

Restrictions

Not in all cases, the use of such a composition is necessarily permissible. The limitation is underfloor heating, heating up, which will lead to the potential melting of the adhesive layer and the violation of integrity.

Not all similar mixtures are focused on working with ceramics and porcelain stoneware. By making the wrong choice when choosing a method for how to stick tiles on plywood, you can simply lower the quality of the results by several times. Look carefully at the label on the packaging, it is always indicated there.

Installation principles

Consider the approach to laying on wood using an elastic mixture. Here's how to glue ceramic tiles to plywood in this way:

• Initially, a wood layer with a thickness of 30 millimeters or more is laid on logs, carefully fixed with self-tapping screws. You should not place logs too rarely, less than half a meter is not recommended.
• The surface of the material is thoroughly cleaned of dust and other contaminants, treated with a tile primer. It is necessary to wait a little longer until the primer dries thoroughly, otherwise the result may not be good enough.
• The adhesive is applied to the floor surface (it is recommended to use a notched trowel), leveled so that the layer is small and as uniform as possible.
• Next, the composition is applied to reverse side tiles, similarly to a small layer.
• Installation begins. The material is oriented in the necessary way (optimally, in advance, before gluing the tiles on the floor to plywood, mark the surface so as not to go astray in the future), after that it is placed and slightly pressed against the floor.
• When the composition dries, the filling of the seams begins. For this, a special grout is used. If there is too much, then it is removed.
• The coating is wiped with a soft cloth and left for some more time. About a day after you decided to glue the tiles to plywood (or earlier), it will be permissible to walk on it.

Alternatives

Although elastic adhesive is the main solution in this situation, other alternatives are used. A simple tile grout does not work very well. But it is also realistic to use it if you use drywall as an intermediate coating. Drywall is attracted to the tree with self-tapping screws. The work ahead is dusty, not very suitable for the kitchen and similar premises.

Liquid nails are a popular alternative. They are applied in the center of the tiles with several points. For grouting in this case, it is important to avoid cement compositions and use only epoxy, otherwise chipping will occur. Can ceramic tiles be glued to plywood? cement mixture basically? Not desirable.

Silicone sealant is the third alternative, worthy, allowing you not to be afraid of coating vibrations, except for especially significant ones. It is used together with a grout with transparent silicone, it has good properties.

Mounting foam is theoretically applicable, but it is important to consider that its volume will increase, but, due to the fact that the coating is laid without gaps, this effect will be compensated.

acrylic blends and acrylic putty similar to liquid nails in properties, but they need to be applied in a continuous layer, and not pointwise.

PVA is also applicable, but, as a rule, only with a thick tree, a thin one will be strongly deformed during the moistening process.

Often during the repair process, the question arises of how to glue tiles on plywood. And first you need to decide what kind of glue is needed for this. Today on sale you can find many types polyurethane adhesives. Their main purpose is to work during installation massive board and parquet. These compositions are preferred because they are able to effectively compensate for the movement of the material during thermal expansion.

Wood, when compared with ceramics, is able to change its original dimensions, being exposed to fluctuations in humidity and temperature of the external space.

This necessitates the use of an elastic adhesive for joining tiles and plywood. This characteristic characteristic of parquet two-component polyurethane adhesive. Its two-component nature is due to the peculiarity of the composition. So, one of the components is a hardener, the other is a polyurethane resin. The ingredients are mixed before use. After that, the composition should be used for a period limited to 30-60 minutes, each manufacturer has its own specific time frame.

When using polyurethane adhesive to lay tiles on plywood, it is impossible to mount an underfloor heating system under the base of the finishing layer, this is due to the destruction of polyurethane adhesive during heating.

It is important not only to decide which glue to use when fixing the tiles to plywood, but also to follow the rules for the work. The first step is to prepare the surface. To do this, the plywood base should be laid on the logs, fixed with self-tapping screws. Logs must be placed in increments of 400 mm or less. The plywood used must be 30mm thick or more. The surface must be free of dust and treated with a primer. After the primer has gained strength, the adhesive must be applied to the base of the floor, and then leveled using a notched trowel. In addition, the adhesive composition must be covered and backside tiles. After laying the product on the subfloor, it must be oriented accordingly, slightly pressed against the plywood. When the composition dries, the seams can be rubbed, eliminating the excess grout mixture. After completion of work, the surface of the tile should be wiped with a soft cloth.

Using elastic glue, you can fix ceramic products of any size on plywood. The elastic composition, in addition to fixing the tiles, acts as a waterproofing agent. Using this method allows you to operate the surface in half an hour, and the grouting of the seam can be carried out almost immediately after the installation is completed.

Tools and materials:

• lags;
• self-tapping screws;
• primer;
• notched trowel;
• grout;
• tile.

Features of laying ceramics on a plywood base

The first step is to lay logs 50x70, then a layer of plywood 18 mm should go, then an adhesive parquet water-dispersion composition is applied. The next layer is 12 mm plywood, which must be smeared with a two-component parquet adhesive, laying a tile on its surface.
It is recommended to use plywood folded in half and fixed with glue, which will provide additional rigidity of the base. If you lay plywood in one layer, then this method can lead to a break in the tile in the area of ​​\u200b\u200bthe seams.
If it is supposed to use a two-component composition, then it is not necessary to prime the plywood. But if the work will be carried out in wet rooms, as for the further operation of the tile, then you can use, for example, Bona R-410.
In the process of work, a dispenser should be used, which is a spatula with slots. This will avoid applying an excessive amount of the composition to the seam, however, if the adhesive still came out in excess, then it will be very simple to remove it mechanically the next day.

The choice of adhesive for laying glass mosaic tiles

It is worth noting that wood, like drywall, metal or rubber, can be attributed to special surfaces that are difficult to process facing. It is absolutely unacceptable to strengthen the tiles on plywood using conventional cement-containing compounds prepared on water based. But plywood, despite the fact that it has a wood base, is a multilayer material that does not react so quickly to moisture surges. But if you also correctly prepare the base by choosing the right adhesive composition, the base will demonstrate itself satisfactorily when finishing with mosaic tiles.

If you want to strengthen glass plywood mosaic tiles, then, when choosing an adhesive composition for this, it should be remembered that the following features should be characteristic of it. The glue should be white, which will hide its color and structure even with transparent tiles. In addition, the composition must have the appropriate marking, which allows it to be used when laying glass, translucent and transparent products. The marking should contain a note about the place and nature of the use of the composition, whether it be pools, facade work, living spaces, bathrooms or work with interior and furniture items.

Mosaic glass tiles can be reinforced with three types of adhesives, each of which fully meets the listed criteria. Among them are white cement-based adhesives. These Italian dry formulations have proven themselves.

It is possible to glue mosaic glass type tiles on plywood using a dry cement-containing composition if:

• the dimensions of the mosaic fragments are not more than 5x5 cm;
• instead of water, the thinner is a latex liquid additive of the same production as the glue.

Cement-based latex additive is able to improve the water resistance, elasticity and adhesion characteristics of cement-based adhesives
