In home decoration, some decoration flaws and loopholes will be found after a period of use, especially the wall falling off, which is a very troublesome thing. So how should we deal with the paint falling off the wall? Let's talk about this topic.

first, check the reasons for the wall falling off.

generally, there are several reasons for wall falling off. The first one is that when workers are painting walls, the ratio of water to paint is not adjusted well. Generally speaking, there is more water, which leads to less coverage of paint per square meter. If the weather changes, especially when it expands with heat and contracts with cold, the paint will easily fall off.

the second reason is that there is no confined space when painting the wall. Generally speaking, when painting putty powder, the painter will repeatedly emphasize that you can't open the window! Because opening the window will lead to the entry of dust, which will affect the effect of topcoat, and because of the relationship between air and humidity, it will cause cracks on the wall.

the third reason is that the wall is wet or even leaking, which causes the wall to fall off.

second, the way to repair the wall.

1. local repair method. If it is caused by the first and second reasons, it is only necessary to remove this part of the topcoat and repaint it. If possible, it is suggested that the putty be made again, and the effect will be better if it is sprayed with topcoat. However, if a large area falls off, it means that the problem is still very serious and needs extensive repair.

2, comprehensive repair method. This situation is suitable for large-scale shedding. Generally speaking, if it is caused by water seepage, then before this repair, we must find the reason, starting from the root, especially to do a good job of waterproofing. If waterproofing is not done well, even if it is repaired, it is useless.

3. Matters needing attention in wall repair.

if the top cracks or falls off, it is enough to remove the water leakage upstairs, as long as the brush is partially shoveled off again, as long as it does not affect the appearance and meets the environmental protection standards, and no special attention is needed. If it is caused by water leakage, be sure to pay attention!

wall paint peeling is a common phenomenon, so you must find a professional master to do it.
