Preparing the base of the floor for the installation of the
tiles. Before laying the tiles with a special adhesive compound, the floor must be carefully prepared. This is especially important, since the strength of the tile fixing is affected not only by the quality of the glue, but also by the presence of unevenness. They can contribute to the deterioration of adhesion between the substrate and the adhesive composition, which, accordingly, will reduce the service life of the coating.
So, you should make sure that when installing the underfloor heating system, the existing mounting technology was observed. The surface of the substrate must be carefully leveled and cleaned of dirt, dust and grease.
For leveling the base, thin filling floors, which do not lose their properties even at high temperatures, are perfect.
In addition, it is necessary to hide all the communication along the floor. To do this, use a special leveling mixture. As a result, unwanted voids with air bubbles do not form under the tiles laid. You can start laying the chosen tile only after the final drying of the substrate. Now it's time to think about which tile glue to choose.
Glue for tiles on a warm floor - how to make a choice?
Please note that the use of conventional adhesive for the installation of heated flooring increases the risk that it will become unusable in a couple of weeks. Due to the fact that traditional glue is too susceptible to high temperatures. That's why the specialists recommend glue for tiles, the floor is not a hindrance. Its feature is the ability to withstand a large number of cycles of heating and cooling.
Most often, these compositions are based on M500 cement or any kind of aluminate cement.
It is acceptable to use an adhesive containing epoxy resins. Special epoxy adhesives, resistant to high temperatures, have excellent adhesion to ceramic tiles and concrete. Accordingly, such formulations are ideal for the device of ceramic coating. Today they are easily found in construction shops and supermarkets. When making a purchase, pay attention to the presence of a label stating that the glue is suitable for this type of floor.
Tiled adhesive for the heated floor - application technology
So, tile adhesive for the warm floor is purchased, the finish is ready for installation - you can start finishing work. To do this, the previously prepared glue is applied to a certain area of the floor with a special grater, and then carefully leveled with a notched trowel. After that, the tile is firmly pressed against the treated surface. The order of its installation remains traditional: the laying is carried out from the center of the room to the side of the corner as far as possible from the entrance opening.
To The amount of glue to be applied directly depends on the size of the selected tile. So, for a square of 30x30 cm it will be enough to handle 70% of its surface. For a larger tile, this figure is increased to 80%.Actually this is also the case when porcelain is used as a finishing coating.
The recommended time for laying the tiles on the floor after it has been treated with glue is 10 minutes. In the reserve you will have about 10-15 minutes to adjust its position. At the end of the day after the end of the installation of the flooring, you can begin to grout the joints, and its regular operation is allowed only after the adhesive has reached the maximum strength.
