During the repair, sometimes it becomes necessary to combine materials of different structure. For example, such a situation may arise when leveling the wooden floor in the hallway with plywood and then tiling it with ceramic tiles. This raises the problem of choosing an adhesive for tiles on plywood.

Technology

Polyurethane adhesive - application features
Polyurethane adhesives are synthetic adhesives that are derived from substances used to synthesize polyurethanes. Polyurethanes are polymers that are film-forming substances having increased stability to the action of gasoline, acids, oils and other aggressive substances

How to choose a heat resistant tile adhesive

Glue for a tile two-component. Features of use
Polyurethane two-component adhesives are used for gluing PVC tiles, ceramics, faience, concrete, metal, wood, polystyrene on absorbent and non-absorbent substrates, also on industrial and sports floors

It is far from always possible to make a solid concrete screed in the apartment, so they are used alternative ways, one of which is leveling the base with plywood.

You can lay linoleum on such a floor or cover it with laminate, but the question remains whether it is possible to lay tiles on plywood, because this is a wooden base that can never be compared in strength to concrete.

Works of professionals and modern technologies allow you to lay tiles on plywood, being sure that it will hold firmly on such a base.

Advantages and disadvantages of plywood base

Before starting work, you need to learn about the advantages and disadvantages of this technology.

pros

  1. The work is done in a short time.
  2. There is no need to bring concrete, reinforcement into the room, lay film waterproofing, and then worry that the ceiling of the neighbors from below does not get wet.
  3. In old-built houses, the low bearing capacity of the building does not allow pouring a heavy concrete screed, so laying tiles on plywood on the floor is almost the only acceptable way to level and strengthen the existing base.
  4. You can lay tiles in rooms with high humidity(bathroom, kitchen).

disadvantages

  1. It is necessary to use plywood with a thickness of at least 22 mm, and when it is mounted on logs, then 30 mm.
  2. In a room with high humidity, it is necessary to take care of reliable waterproofing.
  3. It is impossible to make a warm floor.
  4. If water gets on the base under the tile, then the plywood will delaminate.

After weighing the pros and cons, and having made the final decision in favor of this technology, we will consider how to lay tiles on plywood.

Training

Deciding to stick tile on plywood, you need to take care of the base, making it durable. Depending on the type of existing floor, the approach to leveling it varies.

Smooth wooden floor

Very rarely, an old wooden floor is even, with differences of no more than 5 mm per 1 m2. In this case, it is still recommended to check the condition of the log and boards.

Most often, the problem is observed in the corners of the building, so it is necessary to dismantle the edge board and look under the floor - if the board is intact and not eaten away by bugs, then by setting the board in place, you can continue to work.

Using the rule, you need to check the condition of the floor. The illustration below shows what kind of floor is, and how to navigate the available wooden base when choosing plywood thickness.

note

The undulating floor cannot be leveled with thin plywood, as it will subsequently sag, and the tile will fall off of it.

Wooden floor with significant differences

A very uneven floor will have to be leveled with a wooden crate (as under drywall when leveling walls).

The design of the crate should be such that the plywood sheet is located in the middle of the board. For example, if a board with a width of 50 mm is used, and the sheet has dimensions of 1525 × 1525 mm, then the cell should have inner dimensions 1500×1500 mm, and outer 1550×1550 mm (you need to add 5 mm (or a little more) to the gap between the sheets, otherwise you will have to cut the edges of the plywood later).

The internal parts of the crate, which act as stiffeners, are located at a distance of no more than 500 mm from each other. If tiles on plywood will be laid in the bathroom, then a polyethylene film must be laid under the crate, which serves as a waterproofing material.

The laser level marks the horizon along which the crate is aligned. Pieces of plywood of different thicknesses can serve as supports. Having finished with the alignment of the crate, it should be securely attached to the floor with self-tapping screws, screwing them through the paved supports. Then a sheet of plywood is laid, and fastened with screws to the crate.

Installation of plywood on logs

The most unpleasant, but, unfortunately, the most common situation is that the floor is rotten and must be dismantled, and concrete base fails to do. This is not a judgment because tiling on plywood can be done if the plywood is attached to the joists. The principle is similar to mounting on a crate, only the technology is different.

We bring to your attention a video that demonstrates the process of installing a log and attaching plywood to them.

When fastening plywood sheets, it is important to take into account the possible thermal expansion, so they need to be placed at a certain distance:

  • from each other - 5 mm;
  • from the walls - 1 cm.

The voids near the walls can be closed with a plinth. The seams between the sheets are sealed with polymeric elastic putty.

What kind of glue to buy

How to glue tiles to plywood? This issue deserves detailed consideration, because you will have to glue the tiles to the base of wood material, which is distinguished by its instability.

Therefore, when choosing an adhesive composition, it is necessary to take into account some nuances:

  • A plywood sheet is made up of thin layers of brittle veneer, and if the bond is broken, the plywood will delaminate and no longer be strong. This feature of the material is a good reason to choose an adhesive that does not penetrate deep into the structure of the material.
  • No matter how strong the base, it can still bend slightly under load. In this case, the adhesive cement base will not hold the tile, and it will easily move away from the plywood. Therefore, only elastic adhesive mixtures should be used.

The composition of such mixtures includes highly elastic components:

  • microfiber;
  • fiberglass;
  • silicone;
  • silane and other modifying additives.

Laying tiles

Having made a solid base, consider how to glue ceramic tiles to plywood.

Regardless of the technology used to level the base, work is performed in the following order:

  • If you are not sure that each self-tapping screw is recessed into plywood, you should check again and, if necessary, tighten them with a screwdriver.
  • The existing base must be sanded and dusted with a vacuum cleaner, and then wiped with a damp cloth.
  • Regardless of whether plain plywood is used or moisture resistant, the surface is primed twice. The second time the primer is applied only after the previously applied adhesive has completely dried.
  • Before gluing tiles to plywood in the kitchen or bathroom, an additional layer of waterproofing is applied to the base.

Upon completion of these actions (only after complete drying wooden base) can be tiled on a plywood floor.

The process of laying tiles on plywood


An example of laying tiles on a plywood floor - video

We hope that you have found the answer to the question of how to glue tiles on plywood, and now you can do this work yourself.

The modern market of finishing materials offers a lot of options for finishing the floor. Most often, tiles and plywood protrude into them, which raises the question: is it possible to glue tiles on plywood?

As far as flooring experts are concerned, the technology that explains how to glue tiles to 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 of 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 a concrete screed and involves the use of materials that are 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 good foundation for styling.

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 household appliances that will achieve a high-quality result. 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. The total drying time of the primer is about five hours.

Laying technology

Before installing the tiles on the floor, you need to lay waterproofing material, and the installation of tiles should begin 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 tools. 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 because it dries pretty 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 a well-known name, whose products 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 composition 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 with a 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.

Presented on the market wide range of grout, which can be dry or need to be diluted with water. Never use chemicals to remove grout residues, as they can provoke a chemical reaction.

When repairing, quite often the floor covering is laid on the base. You can level the surface with plywood sheets of various thicknesses. Such a floor is more economical, all work does not take much time, and the cost of a plywood base is much lower than a concrete screed.

Laying tiles on plywood

The advantages include the absence of dirty construction processes. It is worth noting that laying tiles on plywood is more convenient and profitable than other types of bases.

Particularly good similar installation suitable for corridors and kitchens, when it is necessary to complete all work as quickly as possible and, if possible, without unnecessary dirt.

Pros and cons of the process

Laying ceramic tiles on plywood sheets, like other methods of installing flooring, has its advantages and disadvantages.

  • the load on the floor with this method is minimal, which is important for wooden, frame houses;
  • the lining is strong, strong, durable;
  • adhesive compositions play the role of an additional waterproofing layer, and this makes this method acceptable even for bathrooms, kitchens, corridors.
  • with this option, it is necessary to ensure that the thickness of the base, that is, the plywood sheet, is not less than 22 millimeters;
  • for very wet rooms, it is necessary to provide an additional layer of waterproofing, and these are additional costs;
  • with such laying, it is impossible to use the "warm floor" systems.

Features of installing floor tiles on plywood

When asked whether it is possible to lay floor tiles on plywood sheets, experts firmly answer: “Yes”. Although there are pitfalls here: this process will not be easy - it is very responsible and laborious. Careful surface preparation is indispensable.

Unlike other types of flooring, ceramic tiles are heavy, so the plywood base should not be fragile and fragile, the minimum sheet thickness should be twenty-two millimeters.

All sheets must be securely fastened. If even the slightest fluctuations or deflections are observed, additional fasteners should be provided using self-tapping screws.

If plywood is laid on logs, it should be ensured that the step is not large, if necessary, the structure is redone, reducing the step to 30 centimeters.

When laying on logs, the thickness of plywood sheets must be at least 30 millimeters. If this condition is not met, then the load on individual tiles will be distributed unevenly, the tile will begin to peel off and may crack.

Preparatory work

Before starting the installation work, it is necessary to prepare the tools and materials that may be needed for this.

When determining the number of tiles, it is necessary to take into account such factors as the area of ​​\u200b\u200bthe room, the dimensions of one product, laying methods, and the presence of a pattern. In addition, ten percent is added for cutting.

The amount of adhesive composition is calculated in accordance with the instructions indicated on the package.

waterproofing film

It is necessary to prepare such tools and materials:

  • machine for grinding plywood sheet,
  • special elastic glue (if necessary),
  • waterproofing film,
  • ground composition,
  • woodworking screws,
  • tape measure, ruler and pencil,
  • special crosses for seams,
  • grout of the selected shade.

Now you should check the thickness of the plywood layer, which should not be less than twenty-two millimeters. Optimal value is a thickness of twenty-eight millimeters, and for the floor on the logs - thirty. The plywood surface is sanded, cleaned of dust and debris.

If the sheets do not fit snugly, this will have to be corrected, to provide them with additional fastening to the base. Plywood should not sag, have gaps between individual parts. After that, you can start priming. The primer is placed in two layers, moreover, each should dry for at least five hours, after which a new one can be applied.

For bathrooms, after priming, the surface of the plywood is covered with a special waterproofing film that overlaps.

plywood laying process

It is best to fix the tiles using special adhesives that are elastic. Such a tool is the most optimal, since plywood is subject to various linear transformations, reacts poorly to humidity, temperature changes.

It is better to use a two-component polyurethane adhesive, it is also used during installation parquet boards. Such glue, in addition to its immediate purpose, can also perform the function of effective waterproofing. In addition, parquet adhesive sets quickly, you can safely walk on such a coating in thirty minutes.

Adhesive compositions based on a modified silane can also be used. They harden even upon contact with moisture, and completely remove it from the base of the floor. A seam with such glue will be flexible and elastic, which is important for hard floor coverings mounted on a wooden base.

After preparing the base, you can proceed to the subsequent laying of the ceramic tile itself on the floor. The first solid tile is laid in the corner, applying glue in an even layer on the surface of the floor and the tile itself.

The maximum square of the adhesive coating on the base must be equal to one square meter.

The adhesive is applied with a metal notched trowel. After applying the adhesive, the tile is pressed against the surface with your hand, you need to hold it for several minutes so that the solution has time to set. To check whether the thickness of the adhesive layer is the same and whether one tile will protrude above the other, you must use the level.

When installing adjacent tiles, special crosses are used to help control the width of the seam. Such crosses can have a thickness of one to three millimeters. After installation, all seams are treated with grout, the excess of which is removed from the surface of the tile with a damp cloth.

Plywood is wonderful building material when it comes to sheathing large flat surfaces. At the same time, ceramic tiles to this day remain good finishing material without losing its popularity. The only question is how to combine them. Traditionally, tiles are laid on a concrete screed. Both the screed and the tile are not subject to deformation, you can’t say about the wooden and plywood surface. And therefore the question of how to lay tiles on plywood remains relevant.

Ceramic tiles on plywood are laid with 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 of the 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 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. Apply two coats on a flat, smooth surface. After applying each layer, the surface must dry for five hours. If it is necessary to tile in the bathroom, the plywood should be primed with any suitable waterproofing solution.

Laying tiles

Laying tiles should begin with the second row of tiles. The first row can be cut to size and laid 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 usually ranges from 2 to 3 mm, but in rooms with high humidity or temperature fluctuations, the size of the joints can be increased up to 5 mm.

Ceramic tiles on plywood.

24.08.09 16:34

In the course of finishing work, situations arise when it is necessary to combine materials of different structure.

I'll give you an example.

The customer planned piece parquet throughout the apartment.

The foundation "plywood on logs" was made.

In the process of work, he (the customer) decided to lay ceramic tiles in the hallway. The decision is correct, you come from the street, and sand gets on the floor, not a single parquet will last long.

But ceramic tiles are traditionally laid on a screed, which is almost not subject to horizontal displacement.

Wood and ceramics behave differently during operation, plywood is subject to linear changes, which cannot be said about ceramics. In this scheme (plywood is wood), movements will occur when the temperature and humidity conditions change. To connect them, an elastic adhesive is required.

Two-component polyurethane parquet adhesive is best suited for gluing ceramics. Two-component - these are two components, the first is a resin, the second is a hardener. Mixed before use, pot life varies by manufacturer from 30 to 60 minutes. Do not confuse and do not compare with the Soviet "epoxy", this is a different product, both in composition and quality.

There are a lot of two-component polyurethane adhesives on the market, I will give a few: R-770, Stauf-PUK-440. Utsin MK-92, Kesto 2K-PU, Yurgi 2K PU, Kiilto Slim and many others.

The two-component adhesive was originally developed for laying massive board and piece from exotic breeds. The movements of the array with changes in humidity are decent, and many exotics cannot be glued with other adhesives.

The Germans use this glue to lay piece parquet on a concrete screed, bypassing plywood, we just turned this scheme 180 degrees.

It was decided to apply the scheme "ceramic tiles on plywood", two-component adhesive in this case shows itself from the best side.

The only disadvantage of this scheme is the impossibility of installing a "warm floor". For underfloor heating, it is better to use the traditional scheme - a screed.

Scheme of laying ceramics on plywood:

1. logs 50*70,

2. Plywood FSF 18mm,

3. water-dispersion parquet adhesive,

4. plywood FSF 12mm

5. glue 2-component parquet,

6. ceramic tiles.

1. Lay the logs in increments of no more than 400mm, double glued plywood will give additional rigidity to the base, plywood in one is not suitable for this scheme, it is possible to break the tiles in the area of ​​\u200b\u200bthe seams.

2. For 2-component plywood, it is optional, but for wet rooms, you can use, for example, Bona R-410.

3. Use a dispenser (slotted spatula) at 850gr/sq.m. so that there is no squeezing out of excess into the seam, but if it comes out, then mechanically the next day a couple of trifles.

Advantages of this scheme?

1. In houses with wooden floors she is irreplaceable.

3. Glue not only sticks ceramics to plywood, but also acts as a waterproofing agent.

4. The setting of the adhesive is fast enough, the possibility of walking on the laid ceramics after 30 minutes.

5. Grouting ceramic tiles can be done on the same day.

By the way, a new generation of parquet adhesive based on modified silane has appeared.

It hardens through a chemical reaction with moisture in the air, as well as pulling it out of the base.

Now it's not scary getting glue on front side, it is removed with a rag without residue, which does not happen with polyurethane.

I would single out the main advantage of this adhesive - "high residual elasticity of the adhesive line", it is best suited for gluing wood and ceramics.
