What should I do if the wall of the old house drops white ash?

The main reason for the white ash on the wall is that the putty is too thick, the original wall base is not cleaned up, or the first putty is not completely dry, and the next process is carried out. Generally, there will be no problems in a short time after project acceptance, but after a long time, the problems will be exposed.

If it is damp or the quality of building materials, you can buy a bucket of glue paint and paint it again. If the white ash is serious, you can remove the base material first, then scrape the putty twice, and then polish it. Apply it twice at last, just in case. If ash falls in a large area, you can also buy 80 1, 803 or 107 building glue directly. After diluting with water, brush with a tool roller, but pay attention to diluting the glue, otherwise the bottom layer and roller may peel off. If the color is not bright enough, you can paint it again.

What is the reason for the white ash on the wall?

1. foundation treatment is not clean.

If the newly renovated house is dusty, it may be because the wall foundation was not cleaned at that time, or the cement standard was not allowed, and the house structure itself had a large area of hollowing, so the renovation failure should be dealt with in time.

2. Problems in the construction process

In the process of decoration construction, we should also pay attention to the construction process. If the wall is not completely dry after leveling, the next step of construction will also cause the wall to return to slurry. This is the most important problem in winter construction. In this kind of building, electric heating is usually used indoors. For heating equipment, raise the room temperature appropriately to make the bottom wall of the wall completely dry.

3. Humidity at home

For families living in the southeast coast, especially at the bottom, it is a very tragic thing to meet Huangmeitian. Small drops of water will penetrate the whole wall and the whole house will be soaked. Therefore, it is very common for the wall to fall off dust.
