Plywood is wonderful building material when it comes to covering large smooth surfaces. At the same time, ceramic tiles to this day remain a good finishing material that has not lost its popularity. The only question is how to combine them. Traditionally, tiles are laid on concrete screed. Both screed and tiles are not subject to deformation; the same cannot be said about 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 tried the method of laying tiles on plywood using special elastic adhesives. This method is not suitable only when it is intended to install heated floors. Warm floors can only be laid in the traditional way - on a screed. In other cases, if followed correctly technical parameters, laying tiles on plywood is quite acceptable.

Preparing to lay tiles

To ensure that the tiles lie flat and do not peel off, plywood should be used as a base, laid in two layers. 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 reduce deformation to a minimum.

Next stage– preparing the base for the tiles. The plywood should be sanded and cleaned. The surface under the tiles must be perfectly flat. Apply two layers to a flat, smooth surface. After applying each layer, the surface must dry within five hours. If it is necessary to lay tiles 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 trimmed to the right size and put it in last resort. It is recommended to start laying tiles from the far wall of the room. The horizontal installation of the tiles should be constantly checked with a level. For some time, until the glue has set, the tile can be adjusted until the desired result is achieved. Crosses can be placed between the tiles to accurately align the seams. The size usually ranges from 2 to 3 mm, but in rooms with high humidity or temperature fluctuations, the size of the seams can be increased to 5 mm.

Ceramic tiles on plywood.

During the finishing works, situations arise when it is necessary to combine materials with different structures.

Let me give you an example.

The customer planned piece parquet throughout the apartment.

A “plywood over joists” base was made.

While working, 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 can withstand it for long.

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

Wood and ceramics behave differently during use; plywood is subject to linear changes, which cannot be said about ceramics. In this scheme (plywood is wood), there will be movement when the temperature and humidity conditions change. To connect them, elastic glue 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. Mix before use, shelf life varies depending on different manufacturers from 30 to 60 minutes. Do not confuse or compare with Soviet “epoxy”; this is a different product, both in composition and quality.

There are a lot of two-component polyurethane adhesives on the market, here are 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 installation solid board and piece made from exotic breeds. The movement of the array when humidity changes is decent, and many exotics cannot be glued with other glues.

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

It was decided to use the “ceramic tiles on plywood” scheme; in this case, two-component glue shows its best side.

The only disadvantage of this scheme is the impossibility of installing a “warm floor”. For warm floors better to apply traditional scheme- screed.

Scheme for laying ceramics on plywood:

1. logs 50*70,

2. FSF plywood 18mm,

3. water-dispersion parquet glue,

4. FSF plywood 12mm,

5. 2-component parquet glue,

6. ceramic tiles.

1. Lay the logs in increments of no more than 400mm, double-glued plywood will add additional rigidity to the base, plywood in one is not suitable for this scheme, the tiles may break in the area of ​​the seams.

2. For 2-component plywood it is not necessary, but for wet rooms you can use, for example, Bona R-410.

3. Use a dispenser (a spatula with slots) at 850g/sq.m to avoid squeezing out excess into the seam, but if it comes out, then mechanically the next day it’s a couple of trifles.

The advantages of this scheme?

1. In houses with wooden floors she is irreplaceable.

3. The glue not only glues the ceramics to the plywood, but also acts as a waterproofing agent.

4. The glue sets quite quickly, making it possible to walk on the laid ceramics after 30 minutes.

5. Grouting joints 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 in the process chemical reaction with air moisture, as well as pulling it out from the base.

Now you don't have to worry about glue getting on front side, it can be removed with a rag without leaving a residue, which does not happen with polyurethane.

I would highlight the main advantage of this glue - “high residual elasticity of the adhesive seam”; it is best suited for gluing wood and ceramics.

Many novice craftsmen are interested in how to glue ceramic tiles to plywood when finishing kitchen area or bathroom in wooden house. Choosing a suitable composition is quite difficult, since the materials are poorly compatible with each other.

This is exactly what we will talk about in this article.

The main thing

The base composition is usually a two-component polyurethane adhesive made using synthetic substances. The drying process can last from several hours to two days.

The product has a number of advantages that should be mentioned without fail:

• affordable price of the adhesive composition has a positive effect on budget funds consumer;
• a high level of elasticity makes it possible to use products for problematic bases;
• the operating temperature range ranges from -55 to +125 degrees, thereby expanding the scope of application;
• good adhesion allows you to reliably connect almost any materials to each other.

Acquainted with additional information you can if you watch the special video in this article. As for questions that arise during the study process, you can ask them directly in the comments.

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

• Interior partitions;
• Sten;
• Paul;
• Ceiling.

The smooth surface of plywood ensures 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 correctly lay tiles on plywood, you need to thoroughly study the features of this technology, strictly follow the instructions and the diagram of sequential actions for performing this work.

Advantages and disadvantages of new construction 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 installation of modern frame wooden houses;
• Obtaining 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 arranging rooms with high humidity, which include kitchens, bathrooms, corridors.

As for the negative factors, they focus on the following:

• The minimum thickness of plywood that can be used for working with tiles or ceramics must be at least 22 mm;
• Additionally, in wet rooms, enhanced waterproofing must be carried out to preserve wooden structures Houses;
• A heated floor system is absolutely incompatible with installing 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 installation moments and specific pitfalls. Since ceramics and tiles have heavy weight, then the selection and preparation of a plywood base must be approached very responsibly.

1. Plywood for walls must have optimal thickness 28 mm, for floors, when laid on joists, at least 30 mm. Its structure should be strong and not fragile.
2. All plywood structures must be securely fastened with self-tapping screws. During installation, parts of the products must fit tightly against each other, since gaps between them are unacceptable. This is done so that in the future during operation there will be no slightest deflections, which will lead to sagging, peeling and cracking of the tiles.
3. Step between joists during further installation flooring, should be about 30 cm to ensure even distribution of the load on each ceramic element.
4. The number of tiles required for installation must be purchased, taking into account:

• Room area;
• Size of one tile;
• Laying method;
• Feature of the drawing;
• Waste for cutting.

Tools and materials

A set will help ensure high-quality installation of tiles on plywood necessary materials and tools in the form:

• Machines for sanding plywood sheets;
• Special glue with elastic properties;
• Polyethylene film for waterproofing;
• Primer composition;
• Self-tapping screws for wood;
• Notched trowel;
• Pencil for marking;
• Construction level;
• Roulettes;
• Special plastic crosses;
• Rulers;
• Grout of the required shade;
• Special glue.

Main stages of installation

When starting work on laying plywood, you should definitely 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 tight fit and the absence of gaps.
2. Then the plywood is primed in two layers. The period of time 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 covered with a thick overlapping layer on top plastic film to create an additional waterproofing layer.
4. Special action adhesives are used to fix tiles. In addition to their main purpose, they additionally protect the plywood from all kinds of linear transformations, moisture and temperature fluctuations. Two-component polyurethane glue and adhesive compositions based on modified silane are recognized as the best for this work.
5. After all preparatory work arrangement of the base of the floor, proceed to the main laying of ceramic tiles. They start from the opposite corner of the front door.
6. Laying facing tiles for walls has a slight difference. Here this material begins to be laid from the second row from the floor. To prevent the tile from sliding down during work under the influence of its weight, nail down under its lower level wooden slats. So it will hold the entire structure until the moment completely dry cladding, after which the first row is laid.
7. The adhesive must be applied evenly in an even layer, both on the tiles and on the floor surface. For this operation, a notched spatula is used.
8. After applying the adhesive, the tile is pressed by hand to the main surface and held in this position for several minutes to allow the adhesive to strengthen.
9. You need to constantly control the thickness of the adhesive layer, using a building level in your work.
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 range from 1 to 3 mm.
11. After laying all the tiles, the joints between the tiles are treated with grout, the remains of which are removed from work 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, and ceramics and tiles are recognized as excellent finishes.

Modern construction technologies today make it possible to combine these incompatible materials to create any design solution. After all, ceramic tiles, replacing any wooden surface, brings its own special uniqueness to the cozy comfort of the room and creates excellent living conditions.

The modern wide range of tiles allows them to be used not only in the decoration of bathrooms and kitchens, but also in other rooms. Those who are planning to renovate their apartment are often interested in whether it is possible to lay tiles on plywood, because sometimes it is not possible to make a different base for a tiled floor for a variety of reasons. Despite the apparent incompatibility of these materials, it is possible to lay tiles on plywood. Following the recommendations will help you create a smooth, durable floor that will last for many years.

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

Alternative to screed

Plywood can be an excellent replacement for a leveling screed when it is not possible to fill it. For example, veneer material will definitely come in handy if you do not want to dismantle a wooden floor and decide to lay tiles on it. In this case, the plywood will serve as a kind of screed. You can also lay the tiles on plywood, which will be laid directly on the joists, but in this case it is necessary to fulfill certain conditions so that the coating lies on the veneer, almost like on concrete. You understand perfectly well that ceramics is quite heavy material, and therefore a durable surface must withstand it.

Requirements

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

1. Thickness plywood sheet cannot be less than 22 mm.
2. The veneer must be High Quality. This condition does not require the plywood to be free of knots, but the sheets must be firmly glued together. Layering is unacceptable.
3. Plywood boards must be moisture resistant. It is worth adding to this that material of the FBA and BV brands is not suitable for the base under tiles, since it is absolutely incapable of resisting dampness. In any case, plywood of any brand must be treated with coating compounds before installation. This is especially true for FSF brand products, which can become a source of formaldehyde release into the atmosphere.

Perhaps some clarification needs to be made regarding the thickness of the base for the tiles. 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 for the base, since in nature there are no 2 absolutely identical sheets. This means that there will definitely be gaps between them in one place or another, due to which the floor will unnoticeably, but will definitely spring back, which will lead to cracking of the tile covering.

Additional measures

Even a large sheet can spring, since there are no absolutely flat surfaces. In addition, this may be facilitated by various deformations plywood or layer underneath during operation. Therefore, sheets of plywood must be cut into smaller pieces. Naturally, their dimensions must correspond to the lag pitch.

The thickness of the plywood should also depend on the space between the sheathing beams.

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

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

Now about how to prepare the hard plywood base. To make the tiles on plywood “comfortable” (they don’t peel off or crack), you need to:

• treat the veneer with moisture-repellent compounds;
• fasten the veneer sheets with as many self-tapping screws as possible, which should be screwed into wooden base not only along 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;
• coat it twice with primer.

After this, the tiles on plywood will stick much better, because the double primer layer will ensure good adhesion for the glue. It remains to be advised not to rush to apply the next layer of primer. Treatment can only be carried out after the previous coating has completely dried. Typically, this drying process for each layer lasts 5-6 hours.

Tools and materials

This time is enough to check how prepared the equipment, tools and equipment are for laying tiles on plywood. Consumables. To work you will need:

• 2-component polyurethane-based adhesive (it provides strength and elasticity of the connection, as well as additional waterproofing);
• grout for final processing of seams;
• crosses so that the gap between the tiles on the plywood is the same:
• starting rail on which the 1st row will be laid out;
• notched spatula 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 uniform application of glue over the entire surface of the base. Using a level, you can check the horizontal laying of a whole row or one tile and correct its position relative to others.

They begin laying tiles on plywood from the corner farthest from the entrance to the room. It is theoretically possible that a room can have ideal proportions and only whole tiles, 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 installation is carried out from a row in which there will be no fragments. It should be noted that laying fragments against the walls should be carried out only after finishing work with uncut slabs.

Often a situation arises when it is necessary to lay tiles on plywood. This procedure is required when we're talking about about changing the floor or when completing the construction of wall structures. However, the plywood base is very different from the concrete one due to physical properties material, and therefore the technology of tiled cladding here will be somewhat different. Below is detailed analysis How to lay tiles on plywood is where you can see the difference.

What is this article about?

Installation pitfalls

In order to achieve a high-quality result and at the same time not encounter premature collapse of the cladding, two main factors should be taken into account when laying ceramics on a plywood base.

1. The main component of the plywood structure is wood, which has certain properties that are manifested under the influence different conditions. For example, under the influence of water, wood can become wet and swell, and when it dries, on the contrary, it can dry out and shrink in size. In other words, such a foundation will not be static, but will always be in a dynamic state. This can cause damage to the top coating and even its destruction;
2. One of the components of plywood material is resin, the presence of which does not affect better side on the adhesive properties of the base. Therefore, tiles are glued to plywood differently from the classical understanding of this facing process.

Then how to glue tiles to plywood if this cannot be done in the usual way. And is it possible? Modern industry has already provided a solution to this non-trivial problem. To carry out the fastening of ceramics for such a situation, there is a special adhesive composition and auxiliary products have been developed.

Suitable adhesive

Therefore, it is very important to correctly determine adhesive composition, on which tiles could be glued to a base made of wood material. Here you need to take into account the following nuances:

1. With the veneered variety of plywood material, delamination may occur, and therefore it is recommended to use compositions that do not differ deep penetration into the structure of materials;
2. Plywood sheets are quite flexible finishing materials. Under an excessively large load, their bending is not excluded. The gluing of tile elements must be done taking into account that they cannot come off in the event of an accidental impact or when the sheets sag.

Therefore, elastic types of adhesives are the most best option choice. But the use of other alternative compositions is not excluded. Distinctive feature The advantage of such means is that when the base transitions to a dynamic state, they allow the tile to move simultaneously with it.

Their composition necessarily includes the inclusion of such highly elastic components as fiberglass, microfiber, silane, silicone and other modifying agents. polymer additives. Such compositions are usually presented in liquid form, which allows you to skip the moment of tapping the cladding - when pressing on the elements, the mixture is independently distributed on each of the glued sides. However, ceramic coating can be glued to plywood with other types of adhesives. For example, like this:

• liquid Nails;
• NC varnish, foam shavings;
• liquid glass;
• polyurethane foam.

However, such solutions are not the highest quality in terms of gluing surfaces, so you should always choose specialized, proven compositions.

Installation work on the base

Beginners may still have doubts about whether it is possible to lay tiles on plywood. For professional tilers, laying tiles on plywood floors is nothing new. However, the whole process as a whole is quite labor-intensive and painstaking. The technology for installing tiles is identical everywhere, the difference lies only in preparing the base and choosing the appropriate adhesive.

According to the European standard, laying tiles on plywood, chosen as a substrate, is allowed only if the thickness of the latter is in the range from 22 to 28 mm.

When laying plywood boards on joists, their layer can reach about 30 mm. With this thickness, the base provides the necessary rigidity, at which the laid layer of cladding cannot vibrate and crack.

To eliminate the possibility of tension on the whole canvas, it is divided into 4 pieces. Which are fixed to plank floor or a log system in a staggered arrangement. If you need to lay the substrate on the logs, the gaps between them are 30-40 cm.

When fixing plywood, you should not limit the use of self-tapping screws, since attaching them more frequently will ensure minimal deflection of the sheet, which will reduce its vibration. In addition, the screws are screwed in so that their heads are recessed into the thickness of the plywood. This measure is dictated by the need for unhindered grinding of the surface when preparing it for laying tiles and the laying technology itself.

When laying plywood, always monitor its horizontalness using a building level.

However, in practice situations arise when there are fewer sheets specified thickness. But it is not possible to obtain material with the required parameters. What to do then? Use thin material It's also possible. However, in this case the substrate is made of several layers of plywood. In this case, the squares should be laid so that the seams at the bottom of the underlying layer do not overlap the top ones. To give additional hardness to the substrate, the sheets must be glued to each other and reinforced with self-tapping screws.

Please note: due to the dynamism of plywood under the influence of factors such as humidity, temperature changes, the base squares should be placed at some distance from each other and from the walls. The gap between the plywood fragments should be 5 mm, between the plywood and the walls - 1 cm. Subsequently, the void will be covered with a plinth or foamed.

After sanding, remove dust from the surface, since it is almost impossible to glue ceramic tiles to plywood with an uncleaned and unprepared surface. This is done using a vacuum cleaner, a damp sponge or a soft rag.

Another important reminder regarding the base for flooring in rooms with high humidity (kitchen, bathroom). That is, for such rooms they choose not standard plywood, but a moisture-resistant variety. But before gluing the tiles to the plywood, the latter is covered with an additional layer of waterproofing material (this is done on both the wall and the floor). As a waterproofing agent, a special mixture is purchased already mixed or in powder form.

When the primer and waterproofing are dry, the preparation stage is considered complete. After which you can start gluing the tiles onto the plywood.

Installation work with tiles

Having selected a suitable adhesive (two-component, polyurethane, for moving bases, parquet) and prepared the base, installation begins floor tiles on plywood.

Initially, the layout of the elements is done “dry”. The tiled pattern is laid out so that, according to the pattern, the cut elements (constituting at least half of the tile) are located against the walls. If necessary, the center line, which is struck first, is moved slightly in order to create an even and beautiful cladding pattern.

Elements can be glued to tiles glue solution or fix with self-adhesive materials. Then they are rolled over them with a roller, expelling air bubbles. Tiles and plywood are laid with the elements tightly adjacent to each other.

When laying tiles on the walls, a wooden plank is nailed at the height of the second row to prevent the elements from sliding down. This strip will become a support for the entire canvas until the adhesive layer dries. Therefore, it will be removed and the first row will be filled with cut elements.

Since laying tiles on plywood on the floor is also possible different ways, then they start laying out the elements here either from the second row or from the point of intersection of the central lines.

Spreading plywood glue mixture It is recommended to limit the area to 1-4 elements, and not to process an area of ​​more than 1 sq. m. In this case, the product is distributed according to wooden base with a notched spatula. After the adhesive layer has dried, the seams are jointed, having first removed all the crosses, clamps and pegs from them.

That's all the subtleties regarding the question of how to glue tiles to plywood.
