Those who encountered repairing walls in old apartments know how difficult it is to remove paint from their surface. These people often have a question about whether it is possible to put a tile on the paint. The question is not idle, because the release of the surface from the colorful coating is a laborious process, while the work on the preparation of the walls can not be called clean. Of course, it is highly desirable that all the paint be removed. This will allow proper leveling of the surface and lay tiles on it. Those who for some reason want to skip this step should listen to the recommendations that will help put the tiles on the paint with more or less acceptable quality.
To put the tile on the paint, the wall should be perfectly even.
It is necessary to name the conditions under which it is possible to lay a tile on a colorful coating.
- The wall must be level.
- All fatty layers must be removed from the surface.
- Part of the paint still have to be removed.
Layout of tiles on the floor.
And the removal of this part is as follows.
- From the surface, all painted areas are scraped off with the slightest suspicion of peeling.
- Colorful coating should be sanded to make it more rough.
- On the walls, a deep notch is made to ensure that the tiles come into contact with the concrete surface in the future. The incision should be applied at least every 2 cm.
Whether you like it or not, cook it for this job:
- hammer or ax;
- putty knife;
- chisel, chisel or sharpened file (it will be great if you have a puncher on the farm).
At the end of the preparatory phase, remove the debris, remove the dust from the surface and degrease it. Apply to the wall a concrete contact.
Ways of laying
Layout of tiling on the wall.
Now you can choose how to put the tile on the painted wall. One way is to lay the tile on a reinforced base. It is not difficult to make it. Every 10-15 cm in the wall holes are drilled, into which dowel-nails are driven. They need to be connected with a wire to get a kind of grid. Reinforcement will slightly improve the adhesion of the tile to the wall. Another way is to strengthen the adhesive with PVA glue. The additive is added to the already prepared mixture (for example, Ceresit).
In the future, you need to put the tiles exactly the same as on the leveled and peeled surfaces. Only in your case, the wall will be leveled by the adhesive mixture. The laying starts from the bottom and from the most prominent corner of the room. Measure the height of the wall and calculate how many horizontal rows of the whole tile will be obtained (taking into account the gaps).
Place the trim of the cut boards for later, and for the first row, fix the horizontal bar on the wall. Apply a notched trowel to the wall with a notched trowel and press the plate against it for a few seconds. In the same way, glue the rest of the tiles in the row. Do not forget to cross between them crosses and check the correctness of the installation of the plates level. After the installation of the whole tile, remove the starting bar and glue the cut off pieces to the wall.
For the installation of tiles you will need:
- mixer for preparation of glue;
- a container for diluting the mixture;
- зубчатый putty knife;
- a long construction ruler with a level;
- tile cutter, grinder or glass cutter for cutting tiles.
Before laying the tiles, you should try to remove as much paint as possible from the walls.
After laying the tiles, seal the seams with a trowel and a rubber spatula, and remove the excess of the composition with a sponge or rag moistened with warm water.
It is somewhat easier to lay a tile on the painted floor. On it after the device of waterproofing it is possible to create an leveling screed on which the tile will firmly hold. If the floor is concrete, and below it there is a steam membrane, then notches are made on it. After that, a primer is applied to the floor so that the screed is better in contact with the substrate. Painted floors of wood are covered with a fungicidal preparation and covered with a waterproofing agent, on which an equalizing screed is arranged. After it has dried, you can put a tile.
Still, remember that vertical painted surfaces can not be a good basis for laying tiles.
Use this method is possible only in the most extreme cases.
