Using a damp sponge or fine sandpaper, sand the surface to a smooth finish, ensuring
that there are no voids and that the surface is ready to receive paint.

(3) Patching Sheetrock.
There are several different methods of patching sheetrock,
depending on the size of the hole.
For small holes, apply fiber-mesh tape directly over the hole. Cut the tape with joint
compound and feather the edges. Sand or sponge the area smooth after it has dried.
For fist-size holes, cut out a rectangle around the hole with a keyhole saw. Cut a
piece of backing (1 by 2 or 1 by 3) slightly larger than the opening itself. Glue or
screw the backing into place. Cut a patch and glue it to the backing using either
wallboard adhesive or mastic. Apply tape and coat it with compound. Feather the
edges. Sand or sponge the area smooth after it has dried.
For large holes, mark and cut a rectangular section around the damaged area, reaching
from the centers of the nearest studs. Cut a patch and screw or nail it to the studs.
Apply tape and coat it with compound. Feather the edges. Sand or sponge the area
smooth after it has dried.
