Can sand plaster walls be painted directly? How to tile a sand plaster wall?

The sand-gray wall can not be directly painted, and the sand-gray wall base wall can be treated before tiling.

The mortar wall cannot be directly brushed, and the base surface must be treated first. Because sand-lime walls are more afraid of moisture than concrete walls. It should be noted that if the original sand and ash layer is loose, it must be completely eradicated.

Plastering and hanging nets on the wall again can increase the firmness of the wall, and can also avoid bulging, cracking, falling off and other phenomena when painting in the later stage. Soak the tiles in water for about 2 hours before placing them. The purpose is to allow the tile to absorb water in advance, so as to avoid the moisture in the binder after laying to affect the strength of the joint, or to make the binder shrink excessively, resulting in hollow drum transfer.

After submerging in water, remember to clean the surface with a cotton cloth and dry it before applying.

It is recommended to soak in water for two hours before tiling. It not only prevents cracking, but also allows the tiles to fit better against the wall.

Precautions for tiling.

The tiles must be pasted flatUnder normal circumstances, after the master has laid the tiles, he will use a plastic hammer to beat the surroundings to control the flatness of the tile surface in time. If the master does not inspect it, it will not help to wait until the cement is dry. Therefore, the owners should also pay great attention to this aspect.

Tiles are well pasted to measure verticallyOwners should pay attention to check whether the master has carefully measured the verticality of each tile pasted, the main purpose of which is to ensure that all the tiles are like a big glass adsorbed on the wall. If it is a master who is not in place, he will pick up the tile and paste it, and will not investigate the size and appearance of the tile at all.

The tiles must be glued firmlyWhen the master and friend have laid the tiles, the owners must check how firm the tiles are. Because there are some careless masters who apply the false silver of the tile, the edge of the tile is not filled with cement, which eventually causes the tile to fall off. We all know that it is a very troublesome thing to fill in after the tiles have fallen off, so the owners must be cautious in this regard.
