For example, if the subsidy area is 20 square meters and the paving thickness is 4 cm, then the cement consumption at this time is 20 square meters × 0.04× 0.25 ÷ 0.04 = 5 bags of cement; The amount of yellow sand is equal to 20 square meters times 0.04 times 0.75, and the final result is about 0.6 cubic meters of sand.

Precautions:
1, tiles should be fully soaked. Tiles should be fully soaked before paving. This is mainly to make the pores inside the tile absorb water, so that it is not easy to empty and fall off when paving. If the tile is directly attached to the wall without soaking, it is very likely that the tile will directly absorb the water in the cement.
2, choose high-quality cement sand tiles If you want to have good paving quality, you must choose high-quality cement sand, so that the tiles will stick tightly; The key point of choosing cement is to check whether the shelf life has passed. If the shelf life is over, you'd better not buy it. It is best to choose river sand as sand, because river sand contains a lot of water, and the pasting effect will be better.
3. You must choose the position of the first brick. The position of the first brick determines the position of the tile on the whole wall, so the position of the first brick must be selected. If the first tile is in the wrong position, the tiles of the whole wall will be lost.
