Cut and Apply the Fiberglass Tape
Apply Joint Compound
Sand the Surface and Add Paint

Step 1: Prepare the Surface for Patching

Begin by using a utility knife to trim away any frayed edges or overhanging wallpaper. You may be able to push some of the raised edges back into the opening to conceal them. Make certain that no edges will result in raised surfaces on the finished repair.

Step 2: Cut and Apply the Fiberglass Tape

Cut a piece of fiberglass mesh tape, and place it over the hole making certain that the tape lies flat. Use a drywall knife to help you tear a clean edge when tearing the tape.

Step 3: Apply Joint Compound

Apply the compound across the taped area, spreading it thin and smoothing it using a joint knife or a putty knife. Make certain that you apply enough compound to fill the void behind the tape, then work off the excess with the drywall knife. When patching over nail holes, dimple the area by striking it with a hammer (this will provide a better surface for holding the drywall compound). Once compound has dried, sand it smooth and repeat the process with another layer of joint compound, if necessary.
