Steps
Cut the damaged area into a clean square or rectangle with a utility knife. Score through the paper and snap out the loose pieces so the edges are straight.
Measure the opening and cut a drywall patch about 2 inches larger on every side. Lay the patch face down on a flat surface.
On the back of the patch, score the gypsum about 1 inch in from each edge. Snap off the gypsum along those lines but keep the front paper intact.
You now have a raised paper flange around a core that fits the hole. Test fit the core in the opening and trim the core if it is tight.
Spread a thin layer of joint compound around the edges of the hole. Press the patch in so the core sits flush and the paper flange overlaps the wall.
Smooth the flange down with your knife, working outward from the center. Wipe away excess mud so the paper sits flat against the wall.
Apply a thin coat of joint compound over the patch and flange, feathering the edges about 2 inches past the paper. Let it dry fully.
Add a second, slightly wider coat and feather it out again. Let it dry, then sand smooth with a fine grit.
Wipe off the dust, prime the patch and paint it to match the wall.
Tips and common mistakes
Keep the front paper of the patch intact, since it acts as the tape that holds the repair together.
Use a scrap piece of the same thickness as your wall so the patch sits flush.
Let each coat of mud dry completely before adding the next one to avoid cracks.
Wear eye protection when cutting and snapping drywall, and keep blades sharp for clean edges.
Questions
How big a hole can this method fix?
It works well for holes up to about 8 inches wide. Larger holes usually need backing boards or tape and screws.
Do I need drywall tape for a California patch?
No. The paper flange left on the patch replaces the tape, which is why this method is fast.
Can I paint right after the last coat of mud?
No. Let the mud dry, sand it smooth, then prime before painting so the patch does not show through.
