The materials needed for painting the wall include: interface agent, gypsum powder (or quick adhesive powder), white latex, caulking tape, putty powder, 360 mesh water sandpaper, and latex paint (primer, intermediate coat and top coat).
1, how to paint the wall and clean up the old wall
First, the wall should be cleaned, and then the raised surface should be leveled. For oil and stains, the coating should be removed directly.
2. Scrape putty powder
After the wall is processed, it is necessary to re-select putty powder. When choosing putty, it is best to choose putty with high quality and hard texture.
Step 3: polish
Use finer sandpaper to polish the wall to reduce the damage to the wall. If the texture is soft, use 400-500 sandpaper. If the putty used is hard, use 360-400 sandpaper. In addition, when polishing the wall, you must remember not to use too much force to avoid leaving scratches on the wall.
4. How to paint the primer on the wall?
Primer is the foundation for topcoat. When applying primer, you should not only paint evenly, but also make sure to paint every part of the wall. If the wall area is large, some water should be properly applied when painting the primer to ensure that the primer on the wall surface is painted more evenly.
5. Make up
Before painting, you should check the flatness of the wall, because only some pits and small protrusions can be seen at this time, so you must ensure the flatness of the whole wall.
6, how to paint the wall paint
The top coat is actually a top coat. It is best to choose high-quality wool brush or roller as the tool.
7. Maintenance
Under normal circumstances, it takes 4 hours to dry the surface latex paint after construction. Although it takes 4 hours, it can't completely dry the latex paint this time, so the wall can't be treated until the latex paint is completely dry.
The above is the concrete steps and precautions of how to paint the wall. Take a quick look.
