Re: Wallpaper Removed-Sheetrock (drywall) a Mess
Spot prime the damaged areas with a good primer, preferably oil based because it will cause less raising of the exposed paper. This will seal the paper and keep the next step from lifting it even more.
Once the primer is dry, you can apply a skim coating of drywall topping compound. You're just trying to cover the damage and smooth the area out. Once dry you can lightly sand as necessary, top off any low spots, and you're ready for the next phase.
If your walls are textured, you'll have to try to match the texture. There are many different techniques, depending on the type of texture you have. If they're smooth, then it's a matter of sanding the areas to feather them into the rest of the wall.
Prime the entire wall with Zinsser 1 2 3 (blue label ), two coats over the patched areas at least. Finish with a good quality paint such as Kelly Moore or Sherwin Williams.
