Step 3
Apply the joint compound in thin coats---also referred to as "skim coats"---until the flaws are covered. Use a modified arc sweeping motion, with the towel angled about 15 degrees to the wall, and smear the edges to a taper. You can smooth any ridges with a damp sponge if you wish. Let dry completely. Sand between coats.
Step 4
