Repair after removing wallpaper

Question from Krissi: When I removed my wallpaper, in some places it took the paper right off the wallboard(sheetrock). Do I have to mud that or just sand it down before I paint? Any suggestions would be helpful. 

Jake’s Answer: Krissi, This is a pretty typical occurrence when removing wall paper from drywall, especially if the walls were not sealed prior to the paper being installed. The best remedy is to use a product like Kilz, www.kilz.com, a fast drying sealer. Follow the instructions on the can. After the Kilz has dried, apply a drywall compound over the ruff areas and let this dry. It may take two to three coats of the drywall compound to get the walls smooth enough to paint. Sand the drywall and apply a sealer over the walls and then you will be ready to apply your finish coat of paint.
