When old paint chips, flakes, or peels, it leaves behind a shallow depression. You’ll need to repair these spots before painting – new coats of paint won’t hide them. Use a fast-drying patching compound to fill the hole.
1. Scrape away any loose paint with a putty knife or paint scraper. Apply the spackling compound to the edges of the chipped paint with a putty knife or flexible wallboard knife.
2. Sand the patched areas with 150-grit production sandpaper. The patched places should feel smooth to the touch and not have any edges. If the walls have a textured surface you’ll need to texture the patched areas to match.
