Q: I live in a home built in 1979 and want to create a smoother surface on my walls. They were finished with a textured finish of long strokes of finishing mud, which I have heard called a skip-trough finish. I believe what I want is called a Level 4 surface, which looks like fairly smooth plaster with a minimum of texture. Is there a way I can fill in and/or sand down the wall and ceiling surfaces myself before painting to achieve the desired effect?
A: Yes, you can get the finish you want. The process is well within the abilities of the average do-it-yourselfer. Sanding the high spots is not the way to go. We’d "skim coat" instead.
