I had two contractors come to my house. One said I need to use oil base primer before skim coating. The other said that they could just skim coat over the current walls. Which one is better?
First you need to Block Sand the walls using a coarse grade paper, then Stain Seal them with a Pigmented Shellac Sealer Primer (best for your removed wall paper condition)… then finish coat with Sherwin Williams Classic-99 Acrylic… Look here for more specific advice on removing wall paper and repainting: <a rel="nofollow" target="_blank" href="//davmagic.com/paint/PAGES23.html">//davmagic.com/paint/PAGES23.html</a> Good Luck!
