The cement wall is not dry yet. Can you powder it?

You can't dust the cement wall before it is dry, but it must be thoroughly dried. The moisture in the wet foundation will eventually be exhausted in dry weather, which will make the peeling and mildew on the wall more painful. Solution: If the store will install air conditioning, install air conditioning temporarily (doors and windows need to be installed to keep the room well sealed), so that the wall will dry after enjoying air conditioning for a few days. If the store does not consider air conditioning in the future, it can also rent a mobile air conditioner to solve it. I can only think of this way, hoping to solve the problem.

What effect does the alkalinity of wall cement have on fan ash?

1. Impact:

Alkaline flowers appear on the wall, and the wall tiles will fall off after a long time.

2. Reason:

The reason why the wall returns to alkali is that silicate in cement reacts with water vapor to form saline-alkali precipitation. It will lead to peeling, shedding and long hair of putty on the inner wall. At this point, if you stick tiles, the base and the wall can't be completely bonded. Over time, it will develop, empty and fall off due to the alkalinity of the grassroots.

For the treatment of alkali return, it is necessary to remove the base layer and use some alkali-resistant materials to make the alkali-resistant materials adhere to the wall forever. Once alkali comes out, it will be neutralized. Only by putting an end to alkali return can the durability of wall post-treatment be guaranteed.
