1- The level of the surface
Before tiling the walls, the position of the walls should be checked in terms of whether they are level and vertical, as well as whether the angles are right, and if there are defects and problems in the infrastructure, they should be removed according to the opinion of the monitoring body.
>2- Cement sand mortar
On the surfaces intended for tiling, there should not be a covering of straw, plaster and soil, plaster or any other type of mortar other than sand and cement. If the mortar used to tie the wall bricks is a mortar other than sand and cement, it is better to coat the surface of the wall with cement-sand mortar at least 24 hours before tiling (in a ratio of 6 sand and 1 cement, or 10 sand and 1 cement). It should be covered with 3 to 5 mm thick mortar. The above items are for the times when tiling is done with grouting.
2. Tile worse
The tile should not be placed in water for a long time before installation so that it becomes sticky, it is enough to dip the tile in water and use it.
Proper bonding
The width of the band in tiling ponds and pools should always be 2 to 3 mm so that the bands can be filled with mortar. The space between the wall and the tile is 3 cm on average and must be filled with mortar in such a way that the mortar completely covers the surface behind the tile.
2- Clay and white cement prohibited
It is forbidden to pour brick chips, clay and the like, which are often used to glue tiles, on the back of the tile. Also, it is better to avoid using white cement in the preparation of mortar. If white cement is necessarily used in making mortar, quartz powder (glass stone) should be used instead of sand. The best ratio for mixing white cement and quartz is the ratio of one cement and 6 quartz powder to one cement and 10 quartz powder.
2- Bathroom insulation
In the bathroom, toilet, etc., where the insulation is located in the body of the wall, it must be installed on the wire mesh insulation and completely fixed to the wall. The insulation behind the tiling should not be wrinkled.
