Can you paint latex paint if the big white wall is dirty?

1. You can't directly brush latex paint.

2. If there are stains on the wall, it will directly affect the adhesion of latex paint, which is essentially equivalent to wasting latex paint.

3. If you directly brush latex paint, there will only be the problem of uneven wall surface and paint brushing. It is recommended that if you want to brush latex paint, you must do a good job of base treatment.

The correct way to brush latex paint, the steps are as follows:

Basic treatment of old walls。First of all, it is necessary to clean the decorations and dirt on the wall, then sandpaper and then start to paint latex. If the damage to the wall is severe, it is necessary to remove all the original putty, then re-apply the putty, and then apply latex paint.

Clean up old walls。Apply a layer of white cement to the treated area as a base layer. In addition, if you have done smooth treatment before, you only need to polish it when facing this type of wall.

Brush the primer。Latex paint is a topcoat, so before applying a topcoat, be sure to apply a primer. If you don't apply primer, after a long time, the wall will be depowdered, mildew, and even discolored.

Wall repairs。For walls that have been painted, it is very troublesome to repair them all if they want to make a second repair. However, if only that one piece is repaired, the entire wall will have color difference, and the aesthetics will be greatly reduced.

Therefore, it is recommended that if you want to repair the wall, it is best to carry out construction on the entire wall.

Anti-chromatic aberration。On the latex paint for the second time, the most feared situation is that the color difference is different. To solve this problem, it is best to use the same brand of latex paint as the first decoration when brushing for the second time, and ensure that the paint is sufficient, and it is best to paint the entire wall at one time.
