How to repair the wall by yourself
If the problem of the wall is not serious, you can use a grinder to polish the wall, and then clean up the dust and stains left on the wall. After cleaning, you can use latex paint to brush on the wall, which can achieve good results.
However, if the wall is seriously damaged, it is necessary to clean up the grassroots of the wall first, and clean up the putty powder on the wall with a small shovel until it reaches the cement surface. Then, paint with new putty powder, polish the wall when it is dry, and finally apply latex paint to repair it.
Second, how to maintain the wall is not easy to damage.
1. If the material used in the wall is hard, the influence of daily friction on the wall is relatively small. It's just that the walls are easily contaminated with dust. If the dust is not disposed of in time, it will affect the overall effect of the wall, which will lead to difficulties in cleaning up later. So do a good job of cleaning every few days.
2. When cleaning the wall, you can use wax spray to treat the water, and the effect is quite good, which can clean the stains on the wall well. Spray wax water can form a transparent protective film on the wall to prevent the wall from being damaged again.
3. If wallpaper is pasted on the wall, it needs to be cleaned in order to ensure the beautiful effect. At this time, you can use a vacuum cleaner to clean the dust on the wallpaper, which is very simple, and it can prevent more water vapor from existing on the wallpaper and reduce mildew.
