Install the tile on the wooden floor

How to install ceramic on wood floor

Ceramic tiles have long been one of the most practical and preferred soils, and their current availability and variety are increasingly reaching the limits of using this environmentally friendly finishing material.
The ideal base for tiles on the floor is concrete or at least cement mortar. But what do you do with people who have a wooden floor in the house?
There are two possibilities for event development:

 It is necessary to lay the tiles with concrete slabs on the wooden floor of the house. The same question has to be solved by the person who lives in the old house, where all the ceilings are made of wood (not only in the attic, but also among the floors).

As with the second option, the answer is clear: you should not do that.
Tiles: The material is quite heavy, and in old houses with wooden roofs loading bars should not be overloaded.

In 75% of cases, they are currently in a state of emergency. Therefore, the tiles are only allowed if the house has been checked and the floors replaced with new ones. Today, the loading bars of these houses are often converted to metal.
If the roofs are made of concrete and the floor is made of wood, this possibility is allowed.

But here we have to do some preliminary studies. If you decide to lay a tile floor on a wooden floor, you need to be clear about what it means to have such a commitment if of poor basic preparation and poor performance at work.
Possible consequences of laying tiles on a wooden floor:

The tile is placed on the glue. This creates a sealed surface that does not let air through. And for wood good ventilation is important, which does not get wet and rots.
Wood itself is an unstable material that changes state and size under the influence of the environment. The weather is not good either. Therefore, sooner or later, the wooden floor may gain mobility under conditions of high humidity or falling temperatures, which will cause cracking of the adhesive layer (and possibly tiles) and peeling of the coating ceramic. ,

Therefore, before deciding to install the tile floor on a wooden floor, you must check the floor condition and offset. Inspection of the condition of the soil

Begin the survey in the simplest way: Walk along the surface and cover the entire surface. Their job is to find the places where the forums "play".
This could mean: The tables are not very tied to shifts; The picture has already deteriorated and may rot; The decay deformed the trunks of the wood or simply the lining fell underneath.

Each of these options mean that you need to open the floor in these places and make the necessary repairs. If the ground seems to be strong and does not crack or "breathe", you should always open it in a corner. This is necessary to ensure that there are no signs of rot in the boards and delays or areas damaged by wood insects.



How to act in different situations

Depending on the nature of the floor, the preparation of the mosaic surface must be done in different ways. There are several options for event development:
quick preparation of the base;  the device of a ruler moistened on a wooden floor;
 Level the surface without moisture and dirt.

The quick preparation of the parquet can only be used when the wooden floor is in almost perfect condition: it is durable, dry and even.
The preparation requires a moisture-resistant dry wall and a highly elastic polyurethane adhesive, which will compensates for the possible movements of the wooden floor in the future. The work is carried out as follows:

Joined needs to be checked carefully to make sure it is at its horizontal level. If there are differences, they should be aligned with a fiberboard or paperboard of sufficient thickness. Two layers of GKVL are placed on a flat wooden base so that the leaf joints in the upper and lower rows do not coincide. At the same time, a clearance of 10 mm must be maintained between the wall and the floor surface.
The plasterboard joints must be filled with sealant. Then the surface is prepared.
Once the primer has dried, you can place the tiles in the usual way. After all the work, the space between floor and wall close with a socket.

This method is not used in very damp rooms: bathrooms and kitchens. Its advantage is the high speed of the work and the low relative cost of preparing the base. The "wet" method hardly differs from the filling of a conventional cement screed.But here it is necessary that the wood base is solid enough, because the rule has a lot of weight. If the soil is mounted on planks less than 40 mm thick, the stems are sufficiently separated (more than 400 mm). This method does not work.

For the fur device it can be used as a cement and sand mortar with a maximum thickness of 30 mm and self-leveling mixtures based on cement or polymer. Its use makes it possible to achieve a maximum thickness of 10 mm, which is important for small apartments with low ceilings. The work is carried out as follows:

The condition of the soil is carefully evaluated. If the boards are thick enough and the support legs are in a small condition, the floor can be used. If the deviations are rare, it is necessary to reinforce the soil structure with additional blocks formed between the delays. In such a situation, it is necessary that the boards of the raw soils are arranged at a distance of 8-10 mm from each other. This ensures better ventilation. Then the floor must be open in any case
On the floor with prose, you should spread the plate of wood or plywood with a thickness of at least 12 mm. The leaves are connected with a "bandage" of the joints at a distance of 2-3 mm..Then it is necessary to waterproof the surface by coating the film with polyethylene or other impermeable materials. The seal should go to the walls at a height of 7-10 cm. Then the rule is paid.

As you can see, this method requires a lot of work, but the base will be solid and reliable.

The basic dry method is often used by both professionals and internal workers. For this you need a chipboard or plywood. If the leveling material is to be mounted on the surface of the panels, the thickness must be at least 22 mm. If the ground is badly and the material joins the joints, its thickness should be at least 30 mm.

The installation is carried out as follows:
The plywood panels are cut into 4 squares, eliminating the internal stresses in the material. If the plywood is attached to the trunks, the distance between them must not exceed 400 mm. If it is larger, additional brackets need to be installed which will increase the rigidity of the base and will not bend the plywood.
The plywood is staggered, with a change of leaves in the adjacent rows. Use self-tapping wood screws for fastening.  When building the base, it is necessary to check constantly their horizontally so that the mosaics can be easily placed.

If it is not possible to buy thick plywood, you can use a thinner material, but put it in 2 layers and glue them together. The seams of these layers should not collapse. Leave a space of 2-3 mm between the leaves. Between the wall and the floor structure also a technological space of 10-12 mm width is observed. At the end of the job, it is filled with a sealant or mounting foam and then covered with a base. Once the rule has been strengthened, you can place the thumbnail.

Thereafter, the base is treated with an antiseptic and the seal are placed. to improve the adhesion of the plate to the substrate, it is possible to attach a sickle or a net of paint to then apply a primer layer.
What else should be considered?

Since the unit tiled the ground on a wooden basis, this is a rather controversial method to achieve a good result, should you not save.
Experts recommend:
Only buy quality materials from trusted suppliers. Do not use materials such as liquid nails, liquid glass, a mixture of polystyrene and nitrocellulose lacquer to fix the tile (you can find these recommendations). A  qualitative result is not guaranteed.
Buy a good glue that is suitable for working with the base that you have assembled. Not all tile adhesives are suitable for bonding tiles to plywood or chipboard. Do not immediately prepare a large amount of solution: capture quickly and you may not have time to solve it. Watch the technique of work: hurry can be expensive.
