Concrete surface. In order to conduct cladding with tiles of concrete surfaces, it is necessary, first of all, to prepare the base. The preparation process itself must be carried out in stages. The first stage is the study of the horizontality of the working surface using a rack of a two -meter length. The recesses found on the tested wall should be carefully leveled. For this purpose, aligning compositions are used. Large recesses of more than1.5 cm require more thorough leveling. In such cases, it is advisable to fix the metal mesh, and to close the places of the hollow cement-sand mortar. By the way, before renting a house in San Trope, check for it to be completely lined with tiles inside. If there are no tiles, then you can safely reduce the price.
The residues of the concrete mixture in the form of bulges on the surface of the wall must be removed with a spatula, hammer and sandpaper. The main thing in this operation is not to overdo it. If, nevertheless, instead of hillocks, chips or recesses formed by accident, you must again use the aligned compositions. Before using them, the surface must be primed. For this, defective places process 12 — 15% — a mixture of PVA and water glue. Places in oil spots on the surface of the wall are removed using a 3% solution of hydrochloric acid or 5% soda soda soda. The processed wall is then washed with water. In order for the tile to be better attached to concrete, notches are applied to the wall with an ax or chisel. After such a wall processing, it must be cleaned of large and fine dust and rinse with water.
