You should not treat the preparation lightly. Otherwise, the result of the work will be unsatisfactory.
Check that the base has sufficient strength and has the necessary bearing capacity. If the surface has irregularities of up to five millimeters, then they can be blocked using the same adhesive composition. This must be done the day before the installation of the finishing material.
Cooking adhesive mixture
To prepare the solution, the powder is diluted with ordinary water. You should use a liquid with a temperature of 15 to 25 degrees Celsius above zero. If necessary, the elasticizer CC 83 is used instead of water, diluted in accordance with a 2: 1 ratio.
Dry glue is added to the water gradually, constantly mixing the composition. The result should be a homogeneous liquid without lumps. Experts advise using a mixer or drill with the appropriate nozzle. The optimal rotation speed is from 400 to 800 revolutions per second. After preparation of the composition it is necessary to sustain a pause for five minutes. During this time, the mixture will infuse, after which it must be thoroughly mixed again.
Apply adhesive composition
For applying the adhesive composition using a conventional smooth spatula. The tool with teeth prints the comb structure. Depending on the dimensions of the finishing material, the size of the teeth is selected.
When working with large and heavy tiles, experts advise to put a thin layer of mortar on the mounting (reverse) side of the dies. And professionals also apply adhesive to tiles when performing repairs outside the building.
Finishing material, in this case a tile, is not necessary to soak. Dies must be pressed to the surface no later than 15-20 minutes after glue has been applied to the wall. For 20-25 minutes the position of the tiles can be easily adjusted.
In no case can not carry out the installation of tiles butt. It is necessary to arrange the joints. The width of the seams between the dies depends on such factors: the size of the tile, the microclimate in the room, the operating conditions. For reliable grouting, use special mash mix.
