Anonymous users2024-01-24Hello! Cause analysis: The alkali return of the wall, which is the peeling and long hair, is that the excessive moisture in the wall is the main reason, and the excessive moisture forms alkaline precipitates and destroys the wall paint.
Treatment method: 1. Extend the diffusion position around the surface of the wall by 15cm and dispose of it (try to deal with the base layer, that is, the concrete layer) 2. Then wait for the position to dry (2-3 days).
3. Use waterproof mortar instead of ordinary mortar for leveling (note that when the original base surface mortar is 2cm, the waterproof mortar cannot be less than 1cm.) 4. Wait for the location to dry (2-3 days).
5. Finally, hang the net for interior wall insulation.
6. Make wall paint after drying. ok
