Before the country introduced the external thermal insulation policy of the external wall, it was completely feasible to paint the cement wall directly! You know, this practice is very common abroad. However, because the smoothness of domestic civil plastering is not ideal, we usually need to scrape putty to ensure the smoothness of the wall. However, there are several key points to be paid attention to when painting directly on cement walls.

Wire drawing treatment

In the final plastering process of the cement wall, it is suggested to draw lines with a brush to avoid receiving light. This can significantly improve the adhesion of real stone paint.

Spraying or curing

Due to the high alkali content of cement wall, after plastering is completed, necessary water spraying or rainwater curing should be carried out to ensure the complete precipitation of alkali.

Excellent alkali resistance

When choosing a sealing primer, it is necessary to ensure its excellent alkali resistance.

Excellent alkali resistance

Real stone paint should also have excellent alkali resistance. Calcined sand paint is particularly prominent in this respect, which is very suitable for cement walls.
