Step 1 of 6
Prepare the Area
Remove any loose drywall material around the hole. Use a utility knife to clean up ragged edges. For holes larger than 6 inches, cut a clean rectangular shape with a drywall saw.
Tip
Lay a drop cloth below your work area to catch debris.
Step 2 of 6
Apply the Patch
For small holes (under 4 inches), apply a self-adhesive mesh patch directly over the hole. For larger holes, you may need a drywall patch piece secured with furring strips behind the wall.
Common Mistake
Using a patch too small for the hole — the mesh should extend at least 1 inch beyond the damage on all sides.
Step 3 of 6
First Coat of Compound
Using a 2-inch putty knife, apply a thin layer of joint compound over the patch, extending slightly beyond its edges. Press firmly to work compound through the mesh. Let dry completely (usually 12-24 hours).
Tip
Thin coats are better than thick ones. Multiple thin layers prevent cracking and shrinkage.
Step 4 of 6
Sand and Apply Second Coat
Lightly sand the dried compound with 120-grit sandpaper until smooth. Wipe away dust with a damp cloth. Apply a second, wider coat using a 6-inch putty knife to feather the edges. Let dry again.
Warning
Wear a dust mask when sanding drywall compound.
Step 5 of 6
Final Sand and Prime
Sand the final coat smooth. Run your hand over the patch — it should feel seamless. Wipe clean and apply primer over the patched area. This prevents the paint from absorbing differently.
Pro Tip
Use a bright light held at an angle to spot any imperfections before painting.
Step 6 of 6
Paint to Match
Apply paint to match your wall color. You may need two coats for full coverage. For best results, paint the entire wall from corner to corner rather than just the patched area.
Tip
Save leftover paint for future touch-ups. Store in a cool, dry place.
