First, clean up the walls. There is a small white powder on the wall, indicating that the salt in the wall is “precipitated†during the drying process of the cement. At this time, you can brush it off with a nylon brush or iron brush. After a few days of observation, it is determined that there is no longer a white powder. Precipitate, and wait for the cement wall to dry and flat, you can paint.
Second, remove the peeling paint film. Remove the peeling film with a knife or iron brush, and then use a sandpaper to polish the surface.
Third, remove paste paste wallpaper.
Fourth, trim the surface. Fill the cracks in the pit with a batch cutter, wait until it is completely dry, and grind it with sandpaper.
Fifth, deal with wall lesions.
Six, first on the primer. The "primer" coating is used exclusively for wall surfaces that do not require special treatment. For problematic walls, the "primer" that specializes in this particular problem must be selected for the problem.
Seven, then paint. Is the general use of paint.
Eight, brush from top to bottom. After the paint was evenly mixed with a wooden stick, the brushing process started from the ceiling and brushed again, so as not to cause the paint that had fallen from the smallpox to finish the finished wall.
