How do you repair drywall that has torn from wallpaper removal?

Answer 1

You can buy drywall compound already mixed. If you don't have one, buy two putty knives (they're cheap) one small and one larger (for larger jobs.) If there are small holes in the drywall you can simply fill the hole with the drywall compound. You may need to give it a second application or even third application as the compound will shrink as it dries. When I apply it I am sure to make it even with the wallboard and clean up around the edges as this makes it easier to sand with a fine sand paper after. Let it dry over-night and then lightly sand with fine sand paper. For larger holes you will need to purchase a dry wall kit which includes a drywall patch to cover the area. Follow the directions in the dry wall kit which are pretty much the same as covering a smaller hole, you just need more of the drywall compound. The patch is needed to adhere the compound to the wall and to give it stability.

It depends on how bad it is torn. If it just some surface paper, you can use some drywall mud to even out the surface. You would float it over the area of the missing paper, and them feather out the mud over the surrounding good drywall until everything is level. After it is dry, lightly sand the area to remove any bumps or lines. Use a moist sponge to remove any dust from the sanding. All you have to do after that is prime and paint.

If the tear deeply damaged a large area of the inner plaster, you may need a more involved repair. If this is the case, you may need to cut out the damaged section, and replace it. You can cut a square out around the damage, and not actually have to replace an entire wall section. If you are not so sure about your drywall skills, it may be time to call someone.

Another option is to seal the surface with a masonry surface sealer like Guardz or a private brand sealer, repair with joint compound then texture. This should be enough to avoid wrinkles from appearing after painting.
