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

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, 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.

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.

During renovation flooring often replaced with tiles. It is practical and meets all requirements of operation. The tile is attractive, durable, resistant to numerous negative operational influences, including abrasion and mechanical stress.

But for its laying, a strong, rigid and smooth base is required. Concrete pouring and even plywood are suitable for this. How to lay tiles on plywood, is it possible? This issue is not as difficult to solve as it might seem, but there are features that need to be taken into account.

Installation of tiles on a plywood base

How to lay tiles on a plywood base? A number of conditions must be met to perform such work:

When fixing sheets, it is important to ensure maximum rigidity, since deflections and other movements simply cause the floor to creak and crack the coating during use.
Do not lay large solid slabs on the surface, as this leads to damage to the coating. It is necessary to cut a large slab into several separate fragments. This ensures maximum rigidity. The sheets are laid on the base in such a way that there are no cross connections, each fragment is fastened with 9 self-tapping screws to ensure the correct distribution of loads.
If plywood boards are attached to the logs, then the thickness of the sheathing increases to 30 mm, otherwise the tiles simply cannot be laid. The step is taken at 40 cm. If the base does not correspond to this parameter, then you will have to choose another floor covering.

How to lay tiles on a plywood base?

To lay tiles on a plywood base in an apartment, you must fulfill a few simple conditions that will ensure quality and reliability:

For laying the base, you need to take moisture resistant plywood, the thickness of the sheet should be from 20 mm, since the floor must not withstand the most little weight from the mass of tiles. Some experts argue that you can take several sheets of smaller thickness instead of one, but in reality this practice is not entirely justified. There is no particular benefit from laying a multi-layer base, but financial expenses increase several times.
When laying, it is required to check that all sheathing sheets fit snugly against one another, there are no gaps. Plywood is additionally fastened with self-tapping screws, the heads of which are recessed into the material. This ensures that there is no creaking during use, the tile itself is laid as correctly as possible, and does not crack during operation. Plywood is also checked during laying, it should not have cracks, defects, it is impossible to take the usual one for such work, only a moisture-resistant type of coating is suitable.
Before starting installation, upper part sheets must be sanded, otherwise there will be height differences, this usually happens when delaminations. The tile coating will turn out to be uneven, but this should not be allowed.
If laying tiles on moisture-resistant plywood, it is necessary to additionally provide treatment with a primer, waterproofing mixtures. This is especially important for bathrooms, toilets, kitchens, corridors. After processing, it is necessary to wait until the coating is completely dry, only after that you can start further laying work.
Tiles for work can be taken in various formats. The main thing is to choose the right glue, prepare the floor for laying the coating.

In order for the work to be done quickly, it is necessary to prepare tools and materials:

tile;
tile adhesive based on polyurethane;
metal notched trowel for tiles;
rubber spatula for grouting;
grout of the selected color;
tile cutter;
building level;
ruler, a simple pencil for marking the surface.

Step by step instructions for laying ceramic tiles

Laying ceramic tiles is not that difficult, especially if the base is pre-levelled. For this, a two-component adhesive based on polyurethane is used, which provides the most suitable working conditions. The problem is that when laid on a smooth plywood base, the tile flooring can move horizontally until the glue dries.

And polyurethane mixtures can minimize this disadvantage; There will be no deformation of the coating, its damage during operation.

How to lay tiles on plywood? It is enough to follow the sequence of work:

First, you need to mark the surface, it is carried out in accordance with the selected scheme. It can be the usual straight laying, checkerboard, diagonally. With simple laying, it is necessary to immediately mark the position of the first and second row, but the gluing of the tiles itself begins only from the corner of the second row. This is necessary so that after completion of work it is possible to carefully trim the remains, lay rows that will adjoin directly to the walls. It is necessary to advance the laying to the entrance to the room, this allows you not to walk on the already laid tiles.
Glue is mixed into a small amount enough to cover square meter surfaces. The composition is applied to the plywood base with a notched metal trowel, the layer should not be thick, since the strength of the future coating depends on this. The tile is pressed against the base with the wrong side, holding for a couple of seconds. After that, with a rubber mallet, you can gently correct its position, if necessary. Each row must be checked with a building level. This is required so that the coating is neat, even, individual tiles should not protrude above the surface until the glue has dried.
The tile is laid using special spacer crosses, which allow you to conveniently adjust the thickness of the seams. In this case, the surface is beautiful, and the seams after installation are simply filled with a special grout of the selected color. The width of such seams can be different, it all depends on which tile format is used. Generally 3 mm is recommended for standard tiles to achieve an attractive and aesthetic finish.

Without fail, laying of a tile is carried out on the prepared basis. In its role is the floor or wall, which must first be leveled. It should be noted that today there are quite a lot of leveling methods, and one of these is laying plywood. Thus, laying tiles on plywood becomes an urgent issue, and to be honest, the technology of this process.

Let's start with the benefits:

The first is the low cost of such coverage.
You can also note the speed of installation. Which requires less effort and time.
The next advantage is the absence of construction debris.
The plywood lining itself is quite durable and strong.

But do not forget about the disadvantages:

First of all, you need to choose right kind material, which is sometimes quite difficult. Thus, for work you will need sheets of plywood of at least 2.2 centimeters.
For rooms with a very high level of humidity, it will be necessary to provide additional, respectively, this increases the cost of coverage.
And the last is a strict ban on

That is why this technology is rarely used. Although it can be quite good for arranging floors in a kitchen or hallway. In general, in those rooms where repairs are required as quickly as possible, and it is desirable to litter as little as possible.

Features of laying tiles

The first question that often arises is whether it is possible to lay tiles on plywood. And all the experts answer only yes. Of course, as with any other installation, in this case there are a number of difficulties. Therefore, it can be immediately noted that the process of such laying tiles on plywood is quite laborious and must be approached responsibly.

It should be noted that plywood is divided into moisture-resistant and ordinary, which is not suitable for wet work.

First of all, you need to carefully prepare the surface. This is largely due to the characteristics of the tile, and in particular the fact that its weight is much greater than that of other types of coating. That is why you should check the surface for strength. In no case can plywood itself have low strength.

The ideal option of course there will be, which have moisture resistant properties and less mobility

In addition, as mentioned earlier, the thickness of the sheets must be at least 22 millimeters.

Each of the sheets must be securely fastened and pressed to the base. Otherwise, if any deflections or distortions are observed, the coating will last quite a bit.

When laying plywood on logs, it is necessary to ensure a step of no more than 30 centimeters. At greater meaning redesign the structure.

And regarding the lag, it should be noted that in this situation, the thickness of the sheets should not be less than three centimeters.

Preparation for work

Before starting work, it is necessary to carefully prepare, check the availability of all necessary materials and tool.

Also calculate the adhesive mixture and the number of tiles. In the case of tiles, it is necessary to take into account the area of \u200b\u200bthe room, the size of the joints and the size of the tile itself. In addition, the presence of a pattern and a method of laying. You can use our website to calculate.

Speaking of the adhesive mixture, its quantity should be calculated based on the consumption indicated on the package, you can find out how to choose the adhesive mixture and calculate its quantity in a separate article.

Directly for the work you will need the following tools and materials:

Sanding machine for working with plywood.
Waterproofing material (mainly film).
Primer.
If necessary, special glue.
Also, for marking, a ruler, pencil and tape measure.
Self-tapping screws.
Tile.
Adhesive mixture for tiles.
Grout and crosses.

The surface is then sanded and cleaned. The tightness is checked. If necessary, additional fixing with self-tapping screws is provided. Strictly there should be no gaps or deflections of the sheets.

Upon completion of the check, it is necessary to prime the surface. Usually the primer is applied in several layers (2-3). Each of them must dry completely, which, depending on the type of primer, takes from 5 to 12 hours.

Laying tiles on plywood with your own hands

In this case, the use of adhesive mixtures is recommended, which are characterized by an increased level of elasticity, since wood is a movable material. It is in this situation that such a mixture is most optimal, since plywood can be somewhat transformed under the load from the tile. And besides, such material does not tolerate moisture and temperature changes.

The best option would be polyurethane adhesive, which is often used when laying parquet. It is this mixture that will be most effective.

Another advantage will be that in an hour it will be possible to walk on such a coating. That is due to the short setting time.

Another good option become mixtures based on silane. This adhesive is recommended for use in wet areas, as it easily sets even when exposed to moisture. At the same time, the same moisture is completely removed from the surface.

Thanks to the use of this type of mixture, the tile will lie perfectly, and the seams will turn out to be flexible and elastic, which is very important.

The working process

Having finished with the preparation, you can go directly to the question of how to lay tiles on plywood on the floor. Performed this process according to the following technology:

This completes the installation, and you can admire the results of your labors.

What you need to know about laying tiles on plywood

In order to be able to lay tiles on plywood, its thickness must be at least 2.2 cm, it is possible to use several layers, otherwise the coating will not support the weight of the tile.
It is recommended to provide additional fixation with self-tapping screws for a better fit of the coating.
Before tiling the base, be sure to use a strong primer to help ensure the stability of the plywood.
When working, be sure to use the building level. In addition, the laying itself is recommended to start from the far corner from the door.
Care must be taken to ensure that all seams are the same size. For this, special ones are used.
At the end of the work, the selection of grout and its implementation becomes an important factor, since it is it that has the greatest influence on appearance coatings.

On this, the question of how to lay floor tiles on plywood can be considered closed. Strictly following the instructions and recommendations, you will be able to do the installation yourself. And for a better understanding of the topic, we recommend that you familiarize yourself with the videos below.

Often a situation arises when it is necessary to lay tiles on plywood. This procedure is required when we are talking 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 a detailed analysis of how to lay tiles on plywood, and you can see the difference in it.

Pitfalls laying

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

The main component of the plywood structure is wood, which has certain properties that are manifested under the influence different conditions. So, for example, under the influence of water, wood is able to soak, swell, and when dried, on the contrary, dry out, narrowing in size. In other words, such a basis will not be static, being in a dynamic state all the time. This can cause damage to the top coating and even its destruction;
One of the components of plywood material is resin, the presence of which does not affect better side on the adhesive qualities of the base. Therefore, tiles on plywood are not glued in the same way as this facing process is presented in the classical sense.

Then how to glue the 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 tools have been developed.

Suitable adhesive

Therefore, it is very important to correctly determine the adhesive composition on which it would be possible to stick the tile to the base of the wood material. Here it is necessary to take into account the following nuances:

With a veneered variety of plywood material, delamination may occur, and therefore it is recommended to use compositions that do not differ deep penetration in the structure of materials;
Plywood sheets - a fairly flexible look finishing materials. Under excessively heavy load, their deflection is not excluded. The gluing of tiled elements should be carried out taking into account that they cannot move away in case of an accidental impact or when the sheets sag.

Because the elastic varieties of adhesives are the most best option choice. But the use of other alternative formulations is not excluded. hallmark One such means is that when the base moves into 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 polymer additives. Such compositions are usually presented in liquid form, which allows you to skip the moment with tapping the lining - when you press 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;
varnish NC, foam shavings;
liquid glass;
assembly foam.

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

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 a plywood floor is nothing new. However, the whole process as a whole is quite time-consuming and painstaking. The technology for installing tiles is identical everywhere, the difference lies only in the preparation of the base and the choice of a suitable adhesive.

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

When laying plywood boards on logs, their layer can reach about 30 mm. With such an indicator of the thickness of the base, the necessary rigidity is provided, at which the laid cladding layer cannot vibrate and crack.

To eliminate the possibility of tension of the whole canvas, it is divided into 4 pieces. Which are fixed to a plank floor or a lag system in a checkerboard pattern. If it is necessary to lay the substrate on the logs, the gaps between them are made at 30-40 cm.

When fixing plywood, one should not limit the consumption of self-tapping screws, since their more frequent attachment will ensure minimal deflection of the sheet, which will reduce its vibration. In addition, the self-tapping screws are screwed in such a way that their hats are recessed into the thickness of the plywood. This measure is dictated by the need for unimpeded grinding of the surface in preparation for laying tiles and the laying technology itself.

When laying plywood, they always control its horizontalness by means of a building level.

However, in practice there are situations when there are sheets less than the prescribed thickness. But it is not possible to get the material with the necessary parameters. What to do then? You can also use thin material. However, the substrate in this case is made such that it will be represented by several layers of plywood. At the same time, the squares should be laid in such a way that the seams of the bottom of the underlying layer do not overlap with the top ones. To give additional hardness to the substrate, the sheets must be glued to each other and strengthened with self-tapping screws.

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

After grinding, dust is removed from the surface, since it is almost impossible to glue ceramic tiles on plywood with an uncleaned and unprepared surface. Do this with a vacuum cleaner, dampened sponge or soft cloth.

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

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

Installation work with tiles

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

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

Elements can be glued to the tile adhesive mortar or fixed with self-adhesive materials. Then they are rolled over them with a roller, expelling air bubbles. Tiles and plywood are laid with a tight fit of elements 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 slipping. This bar will become a support for the entire canvas until the adhesive layer dries. Therefore, it will be removed and filled with cut elements in the first row.

Since you can also put tiles on plywood on the floor different ways, then they start laying out the elements here either from the second row, or from the point of intersection of the center lines.

It is recommended to limit the spreading of plywood with an adhesive mixture to an area within 1-4 elements, and not to process an area of more than 1 sq.m. In this case, the agent is distributed according to wooden base notched trowel. After the adhesive layer has dried, the seams are jointed, having previously removed all the crosses, clips and pegs from them.

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