Floors in a house with a tiled roof have long become commonplace. In kitchens and bathrooms without such coatings is difficult to manage. The problem can arise when it is necessary to lay tiles (tiles) on a wooden floor.
Laying tiles on a wooden floor includes the following steps: dismantling of wooden coverings, inspection of the floor, preparation of screed and coating, laying tiles on the wooden floor, grouting the seams of the floor.
If the base of the house is erected from a tree and the floor screed is made of a wooden beam, then some special conditions appear. Laying tiles on a wooden floor requires a specific approach related to strengthening the base. However, all these difficulties are surmountable, the laying can be done by oneself.
To the generalized name "wooden floor" it is possible to carry wooden, parquet coverings and coverings from wooden plates (ДСП, plywood, a laminate), laid on a wooden screed (logs). Such floors have a number of features. After their manufacture within two years there is a subsidence of elements. Although this displacement is invisible to the eye, it can break the strength of the tile bundle. The tile can peel off from the coating, and sometimes even crack.
The scheme of arrangement of a wooden floor on logs.
Wood is highly dependent on moisture and temperature factors. It is noticeably broadened and narrowed depending on this effect. Any linear changes in the wooden floor elements have a significant effect on the strength of the tile coating.
Vertical dynamic loads (walking, installing furniture) on the wooden floor lead to its oscillatory movements. This phenomenon requires cushioning pads under the tile. In addition, the complete elimination of the possibility of "breathing" for wood is fatal, as it leads to decay, as well as the development of mold and fungi.
These specific properties of wooden floors cause increased requirements for their preparation before applying ceramic tiles (tiles). In general, the process of laying a tile on such a floor includes the following steps:
- Dismantling of soft and light topcoats.
- Examination (examination) of sex.
- Preparation of screed and wooden cover.
- Laying tiles on a wooden floor.
- Grouting of tile joints.
For laying tiles on a wooden floor, the following tool is needed:
- putty knife;
- резиновый putty knife;
- cutter for tile;
- hammer (kyivanka);
Dismantling of coatings
The first stage of laying the tiles is due to the need to free access to the main covering of the wooden floor. The dismantling of soft and thin topcoats (linoleum, plastic, felt, carpet, etc.), as well as plinths. In other words, all materials superimposed on the basic flooring must be completely removed.
Scheme for dismantling the wooden floor.
The next step is a thorough examination and examination of the condition of the wooden floor. The purpose of this stage is to assess the condition of the wooden elements by visual inspection and determine the strength and compliance of the floor covering with vertical dynamic loads throughout its area. For this, the pressure is created alternately in different parts of the floor and the presence of deformation and oscillation of the surface is determined. If the coating with dynamic loads (the weight of a person when walking on the floor) is subject to even minimal fluctuations, then the tile can not be applied without additional hardening.
If there is damage to the flooring or compliance is observed with the load, then it must be dismantled to inspect the elements of the floor screed. Coverage should be dismantled and in the presence of creaking or other fears for the integrity of the log. After dismantling of boards or slabs, the condition of each lag and the places of their connection and fastening is checked.
Thus, at this stage, the need to replace or harden the floor screed elements and the main floor covering is determined. It is specified the need to install additional reinforcing elements or filler to eliminate the compliance of the wooden coating under the influence of vertical dynamic loads. The necessity and degree of equalization of the floor surface is determined.
Preparing a wooden floor for laying floor tiles.
Preparation of a wooden floor includes a number of operations: repair and strengthening of wooden screed; elimination of paint and varnish coatings; leveling of the wooden flooring. If damage to logs or beams is noted, they must be replaced. Due to the fact that the ceramic tiles considerably weight the floor covering, you should check the distance between the lags. With the step of setting the log more than 0.5 m, it is advisable to fix additional bars. All wooden elements of the screed are treated with an antiseptic.
If the flooring (boards or slabs) has been painted, paint or varnish must be completely removed from the floor before laying the tiles. This can be done mechanically using a grinding machine or chemically using solvents. The surface of the floor after the treatment must be ground.
Leveling of the floor surface is done by laying sheets of plywood, fiberboard or drywall. Between the sheets a gap of about 3 mm is formed to vent the wooden screed elements. The sheets are disposed with a displacement (the principle of brick in the masonry of the wall) relative to each other. It is advisable to treat the material with a waterproof coating. The leveling of the surface is checked with a level.
The main task of the tile stacker on the wooden floor.
Before the direct laying of the tile, the final preparation of the floor surface is carried out, consisting in creating a layer that ensures a reliable connection of the tile to the floor surface. First, a thick layer of thick drying oil is applied to the surface of the wooden floor. Before the composition dries, the layer of the mesh is densely packed so that the linseed can fill the grid cells. Mesh is superimposed on the entire surface of the floor. Such a coating must dry up and form a monolithic layer. Then a metal reinforcing mesh is tightened from above, which is fastened with screws. Finally, the grid is covered with a mixture of liquid glass and sand (liquid glass - 2 parts, sand - 2 parts, water - 1 part). Cover give time to dry. The surface must be strictly horizontal and level.
How is the adhesive preparation carried out? Laying tiles on a wooden floor requires the use of a special glue for gluing tiles. Such an adhesive is realized as a dry powder, it is only necessary to mix it in the required amount of water according to the instructions. The most suitable glue is cement based. Drying time is 2-4 hours.
The main condition: do not dilute a large amount of glue, which will not be used in 2 hours.
Laying tiles on the surface
For proper tile laying, it is necessary to pre-mark the surface of the floor. To do this, from the center of the longest wall of the room, a line to the opposite wall is perpendicular to it. The same operation is carried out on short walls.
Laying tiles on the surface.
Laying tiles on a wooden floor begins with one of the corners formed by the intersection of two central scribing lines. Approximately 1 m² of floor surface is applied glue. It is applied evenly with a spatula or spatula. The tile is pressed into the adhesive layer. In the corners, templates (beacons) are installed to set the desired gap between the tiles. So tiles are laid on the entire square, treated with glue, and gradually the laying moves from the center to the wall.
After covering the first quarter of the floor with tiles, tiles are laid in the next quarter (from the center to the wall). When laying it is necessary to control the level of the tile (horizontal surface). Correction of the level of laying is made by the thickness of the applied adhesive layer.
When laying the tile near the wall, it sometimes becomes necessary to cut tiles. It is best to use a special cutter for tile, which makes it possible to cut the tiles in the same way. After laying all the tiles, the horizontality is checked. Sponge removed excess glue.
Conclusion: grouting joints
After the glue dries, you can make the final stage of laying the tiles on the wooden floor - grouting the tiles between the tiles. The seams are wetted with water with a brush or a rag. Then, using a rubber spatula, special cement grout is stitched into the seams to grout the joints. The surplus mass is removed. After pre-drying the solution (approximately 20-30 minutes), the tile is treated with a moist sponge to remove any contamination.
Laying tiles on a wooden surface has some special features regarding the preparation of the floor. In general, the stacking technology has been worked out and is quite accessible.
