How to Repair Holes in Drywall
Drywall holes are one of the most common home repair jobs — door handles, moving mishaps, and old anchors all leave marks. The good news is that most holes are straightforward to fix with basic tools and an afternoon of patience. Here’s exactly how to do it.
What You’ll Need
Materials: drywall patch panel or mesh patch, drywall screws, joint compound (also called mud), drywall tape, sandpaper (120 and 220 grit), primer, matching paint.
Tools: drywall saw or utility knife, screwdriver or drill, taping knife (6″ and 10″), sanding block, paintbrush or small roller.
Step 1 – Clean Up the Hole
Use a utility knife or drywall saw to cut away any loose, crumbling, or torn drywall around the hole. You want clean, straight edges — a ragged hole is harder to patch neatly than a clean square or rectangle.
Step 2 – Cut and Attach the Patch
For holes under 10cm, a self-adhesive mesh patch works well — just press it over the hole. For larger holes, cut a piece of drywall slightly larger than the hole, score it to fit, and secure it with drywall screws into the surrounding studs or a backing board.
Step 3 – Apply Joint Compound
Apply drywall tape over the seams first, then spread joint compound over the patch with a taping knife. Feather the edges out wide — at least 15–20cm beyond the patch. Let it dry fully (usually overnight), then apply a second thin coat. Two or three thin coats always beats one thick coat.
Step 4 – Sand Smooth
Once the final coat is dry, sand with 120 grit to knock down any ridges, then finish with 220 grit for a smooth surface. Wipe away dust with a damp cloth before painting.
Step 5 – Prime and Paint
Always prime the patched area before painting — unprimed joint compound absorbs paint differently and the patch will show through. Once primed, apply your topcoat. Blending paint on older walls can be tricky — you may need to paint the full wall for an invisible repair.
Complexity Rating: 20 / 100
Small drywall patches are genuinely manageable for most homeowners. Where it gets harder is achieving a truly invisible finish on textured or painted walls — that’s where most DIYers end up with a visible “cloud” on the wall.
When to Call a Pro
If the hole is large, if you’re dealing with water-damaged drywall, or if you just want a seamless finish without the trial and error, it’s worth calling in a pro.

Repair by Damage Type
Not all drywall damage is the same. Here’s how to approach each scenario:
Nail Holes & Small Dings (under 1/2″)
Use a lightweight spackling compound. Apply with a putty knife, let dry 30–60 min, sand smooth with 120-grit, then prime and paint. No mesh or backing needed.
Medium Holes (1/2″ – 4″)
Use a peel-and-stick mesh patch or a California patch (cut a drywall square with backing flaps). Skim two thin coats of joint compound, feathering edges 6–8″ out. Sand between coats with 150-grit.
Large Holes (4″ – 12″ or bigger)
Cut a clean rectangle around the damage. Install a backing board (1×3 or 1×4 wood strip) screwed to the existing drywall on each side. Cut a patch to fit, screw it to the backing, tape all seams with paper tape, and apply 2–3 coats of compound. Allow full drying (24 h per coat in humid Toronto weather) before sanding.
Water-Damaged Drywall
Stop the leak first. Remove all softened or discoloured drywall — it won’t hold compound and may harbour mould. Treat the framing with a mould-inhibiting primer before installing new drywall. Use moisture-resistant (green board) drywall in bathrooms or basements.
Textured Walls & Ceilings
Match the existing texture before painting. Common methods: orange-peel (spray can or hopper), knockdown (trowel technique), or skip-trowel. Test on a scrap piece first. Most Toronto-area homes from the 1980s–2000s have a light knockdown texture.
