How to Patch a Hole in Drywall: Small, Medium and Large Repairs

Knowing how to patch a hole in drywall is one of the most useful DIY skills a homeowner can learn. Doorknobs, furniture and picture hooks all leave marks over time. Fortunately, you do not need a contractor. With a few inexpensive supplies, you can make the wall look new. This guide covers small, medium and large holes.

Tools and Materials

• Putty knife and 10-inch taping knife
• Lightweight spackle or joint compound
• Self-adhesive mesh patch or drywall scrap
• Fine-grit sanding sponge (120 to 220 grit)
• Utility knife and drywall saw
• Primer and matching paint

How to Patch a Hole in Drywall: Small Holes

Small holes, such as nail or screw holes, are the easiest to fix.

1. Brush away loose debris.
2. Press a small amount of spackle into the hole with a putty knife.
3. Scrape the surface flat.
4. Let it dry according to the label.
5. Sand lightly, then prime and paint.

If the spackle shrinks as it dries, add a second thin coat.

Medium Holes (Up to 5 Inches)

Doorknob dents and small impacts usually fall into this group. A self-adhesive mesh patch works best.

Step 1: Clean the Edges

Use a utility knife to trim any broken, crumbly edges. Wipe away dust.

Step 2: Apply the Patch

Center the mesh patch over the hole. Press firmly so it sticks flat. The mesh should cover the damage completely.

Step 3: Spread Joint Compound

Use a taping knife to spread a thin layer of joint compound over the patch. Extend it a few inches past the edges. Feather the outer edge so it blends into the wall.

Step 4: Add More Coats

Let the first coat dry fully. Then apply a second, slightly wider coat. A third coat may help on deep holes. Each layer should be thin, because thick coats crack.

Step 5: Sand, Prime and Paint

Sand the area smooth with a fine sponge. Wipe off dust. Apply primer first, because bare compound absorbs paint unevenly. Finally, paint the repair to match the wall. See our guide on how to paint a room for finishing tips.

Large Holes (Over 5 Inches)

Large holes need new drywall and a support frame.

1. Cut the hole into a clean square or rectangle with a drywall saw.
2. Screw wood strips behind the opening for backing.
3. Cut a drywall piece to fit the hole.
4. Screw the patch to the backing strips.
5. Cover the seams with joint tape.
6. Apply three thin coats of compound, sanding between each.

Always turn off power and check for wires and pipes before cutting. The Consumer Product Safety Commission offers general home safety guidance.

Tips for a Seamless Finish

• Use several thin coats instead of one thick coat.
• Feather the edges wide to hide the patch.
• Sand gently, and avoid gouging the wall.
• Match the wall texture with a spray texture or sponge if needed.
• Prime before painting every time.

Final Thoughts

You can now patch a hole in drywall of nearly any size. Choose the right method, apply thin coats and sand carefully. With patience, the repair will blend in so well that no one will notice it.
