Drywall damage is an all-too-common problem, whether caused by water damage, punctures, or other accidents. The good news is that repairing damaged drywall is a relatively straightforward process that can be completed in a few hours with the right tools and materials.
The first step is to assess the extent of the drywall.
Once you have assessed the damage, gather the following materials:
Use a utility knife or drywall saw to cut out the damaged section of drywall. Make sure your cuts are clean and straight, and cut slightly beyond the damaged area.
Place the new piece of drywall into the opening and secure it with drywall screws. Space the screws evenly, approximately 6 inches apart.
Apply drywall tape over the joints between the new and old drywall. Smoothen it with a putty knife. Apply a first coat of joint compound and let it dry. Once dry, apply a second coat and smooth it out. Allow it to dry.
Once the joint compound is dry, sand it smooth with sandpaper. Apply a final coat of joint compound to fill any remaining imperfections and smooth it out. Let it dry and sand it again.
