In home decoration, cement and mortar are indispensable materials. Cement mortar is used for the laying of floor tiles, wall tiles and masonry. It not only enhances the adsorption capacity of surface materials and base layers, but also protects internal structures. At the same time, it can be used as a leveling layer for building rough surfaces.

Many people believe that the greater the proportion of cement in the entire mortar, the stronger its adhesiveness, and therefore often disagree with the decoration company in terms of how much cement is used. In actual fact, in the case of paste tiles, if the cement number is too large, when the cement mortar condenses, the cement absorbs a large amount of water. At this time, the ceramic tile surface moisture is easily absorbed and cracked, shortening the service life.

Cement mortar should generally be cement: sand ratio of 1:2 (volume ratio); the proportion of tiles should be no more than cement:sand=1:3 to stir.

At present, there are many varieties of cement on the market, such as Portland cement, ordinary portland cement, and slag portland cement, etc. Silicate cement is commonly used for home decoration.

The principle of buying cement and sand

In order to ensure the quality of cement mortar, the cement must be paid attention to whether it is 425 Portland cement produced by Dachang. Sand should be selected sand, the sand thickness of the particles is very suitable for use in cement mortar. Many customers think that the better the sand, the better the mortar is, in fact, a misunderstanding. Too fine sand adsorption capacity is not strong, can not produce a large friction and stick to the tile.
