Use a California patch (butterfly patch) for medium holes in drywall
Cut a piece of new drywall slightly larger than the hole (2-4 inches larger in each dimension). Place it face-down and score the back paper and gypsum core to the exact size of the hole, but leave the front paper intact as an oversized flap. Snap off the excess gypsum, leaving the front paper extending beyond the patch like a border. Apply a thin layer of joint compound around the edges of the hole on the wall. Press the drywall plug into the hole with the paper flaps folding flat against the surrounding wall. Smooth the paper flaps into the wet compound. Apply additional compound over the entire patch, feathering the edges. Let dry, apply a second coat, sand smooth.
Why It Works
The California patch (also called a butterfly patch or hot patch) is self-supporting -- the overhanging paper acts like built-in tape, bonding the patch to the wall without needing backing support, clips, or furring strips. The paper layer provides the same reinforcement as drywall tape, creating a strong, seamless repair. Professional drywall finishers use this technique because it is fast and produces an invisible result.
Tips
- Ideal for holes between 1 and 6 inches in diameter (fist-sized holes, doorknob damage, plumbing access holes)
- Use drywall that matches the thickness of your existing wall (most residential walls are 1/2 inch)
- The paper flaps should extend at least 1 inch beyond the hole on all sides for good adhesion
- Score and snap the back carefully -- if you accidentally tear through the front paper, start over with a new piece
- Apply compound in two thin coats rather than one thick coat; feather the second coat 8-10 inches wide for an invisible blend
- This patch method costs almost nothing if you have a scrap of drywall and some compound on hand
- Common mistake: making the paper flaps too small -- they need enough surface area to create a strong bond with the surrounding wall
