What You’ll Need
- Self-adhesive drywall mesh patch (sized to cover the hole)
- Pre-mixed joint compound
- 4- to 6-inch putty knife
- 120-150 grit sanding sponge or sandpaper
- Primer
- Matching wall paint
- Paintbrush or mini roller
- Dry cloth
- Utility knife
Steps
- Clean the hole. Remove any loose drywall paper and dust from around the hole. Use a utility knife to trim away frayed or torn edges. A clean surface helps the mesh patch stick properly and keeps the compound from lifting later.
- Apply the patch. Peel the backing off the self-adhesive mesh patch. Center it over the hole and press it firmly into place. Run your finger around the edges to make sure every part of the mesh is flat against the wall — any lifted corner will show through the compound.
- Apply the first coat. Scoop some joint compound onto your putty knife. Spread a thin layer over the patch, starting from the middle and working outward. Feather the edges so the compound tapers into the surrounding wall, not leaving a hard line. I keep a small tub of joint compound in the garage — it’s cheap, lasts forever, and comes in handy for exactly these moments.
- Let it dry. Wait for the first coat to dry completely. This usually takes 2 to 4 hours, depending on humidity and how thick you applied it. The compound will turn a uniform white when it’s ready for the next step.
- Sand and apply the second coat. Lightly sand the dried compound with a 120-grit sanding sponge — just enough to knock down any ridges. Wipe away the dust with a dry cloth. Apply a second thin coat, feathering the edges a bit wider than the first time to blend further into the wall.
- Sand smooth. Once the second coat is dry, sand again until the patch feels completely smooth under your hand. If you close your eyes and run your palm over it, you shouldn’t be able to tell where the patch is. Wipe off all dust with a dry cloth.
- Prime and paint. Brush a thin layer of primer over the patched area and let it dry. Then paint with your matching wall color. A second coat of paint helps hide any slight texture difference and makes the repair invisible.
Pro Tips
Tip: Use a putty knife that’s wider than the patch itself. A 6-inch knife gives you more control when feathering the edges, which means less sanding later.
Caution: Sanding joint compound creates a very fine dust that can irritate your lungs and spread through the house. Wear a dust mask and open a window. Wipe down nearby surfaces with a damp cloth afterward to trap any airborne dust.
