How to prepare the foundation?
Before starting repairs, it is necessary to properly prepare the base. Be sure to clean and dry the work surface. If necessary, various defects are eliminated, such as cracks, gouges, chips and much more. And also oil stains are removed from the base, grinding is carried out. Do not take preparation lightly. Otherwise, the result of the work will be unsatisfactory.
Check that the base is strong enough and has the required load-bearing capacity. If there are irregularities up to five millimeters on the surface, then they can be covered using the same adhesive composition. This must be done one day before the installation of the finishing material.
Preparing the 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, use CC 83 modifier instead of water, diluted in a 2: 1 ratio.
Dry glue is added to the water gradually, constantly stirring the composition. The result should be a homogeneous liquid without lumps. Experts advise using a mixer or drill with an appropriate attachment. The optimum rotation speed is from 400 to 800 revolutions per second. After preparing the composition, it is necessary to pause for five minutes. During this time, the mixture will infuse, after which it must be thoroughly mixed again.
An ordinary smooth trowel is used to apply the adhesive. The comb structure is profiled with a serrated tool. Depending on the size of the finishing material, the size of the teeth is selected.
When working with large and heavy tiles, experts advise adding a thin layer of mortar to the mounting (back) side of the dies. And also professionals apply the adhesive to the tiles when performing repairs outside the building.
The finishing material, in this case the tile, does not need to be soaked. The dies must be pressed to the surface no later than 15-20 minutes after the glue has been applied to the wall. For 20-25 minutes, the position of the tiles can be adjusted without problems.
In no case should the tiles be installed end-to-end. It is imperative to arrange the joints. The width of the joints between the dies depends on such factors: the size of the tiles, the microclimate in the room, the operating conditions. For reliable grouting, use special grouting mixtures.
See below for more details.
Removing glue particles
To remove fresh residues of the composition, it is enough to rinse them with warm water. In the event that the glue has time to dry, a mechanical removal method is used. The optimum air temperature for finishing work varies from 5 to 30 degrees Celsius.
