How do you repair holes in quarter inch thick drywall?
(to spread the joint compound). Cut a larger, well-shaped hole around the hole that you are trying to repair, in the shape of a rectangle (for example, if you had a football-helmet shaped hole in your wall, you’d cut around the hole in the shape of a rectangle) and remove the excess drywall. Cut the drywall patch to the same size as the hole you just made. Screw the piece of drywall into the joists inside the hole. Use joint compound to cover the drywall screws and blend together where the drywall patch meets the old drywall. After it had dried, sand it even. Prime and paint.
