Patch a hole in drywall
The size of the hole tells you how to patch it. Nail holes and small dents need spackle, doorknob-sized holes need a mesh patch, and anything bigger than your hand needs a new piece of drywall. The trick is to use thin coats and give each one time to dry. A patch usually shows because of its edges, not the hole, so the extra minutes you spend feathering the compound out wide are what make it disappear.
Thin coats, not thick ones
The biggest mistake beginners make is one thick coat of compound. It shrinks, cracks, and leaves a bump you can see from across the room. Pros put on two or three thin coats, each one wider than the last, so the edges fade into the wall.
What size hole do you have?
Tiny and fast. Spackle fills them in a minute.
Usually 2 to 4 inches across, right at knob height. A self-adhesive mesh patch handles them.
Plastic anchors often pull out a chunk of gypsum. Treat them like a medium hole.
Anything bigger than your hand needs a new piece of drywall cut in, with a wood backer behind it for support.
| Hole size | What to use |
|---|---|
| Nail or screw hole | Lightweight spackle and a putty knife |
| Up to about 1/2 inch | Spackle, two thin coats |
| Up to about 6 inches | A self-adhesive mesh patch and joint compound |
| Bigger than about 6 inches | Cut in a new piece of drywall with backing strips |
Patch the hole, step by step
- Clean up the edgesTrim loose paper and crumbled gypsum with a utility knife so the surface is flat. Fuzzy paper edges will show through paint.
- Fill small holesPress spackle in with the knife, then scrape it flat. Slightly overfill, because it shrinks as it dries.
- Cover medium holes with meshStick a mesh patch over the hole, then spread a thin coat of compound over it, reaching about two inches past the edges. For holes too big for a mesh patch, cut the hole square, screw wood backing strips inside, screw in a new drywall piece, and tape the seams before coating.
- Big holes: put in a new pieceFor a hole too big for a mesh patch, cut it into a neat square. Screw wood strips inside the wall along two edges, then screw in a piece of drywall cut to fit. Tape the seams and coat them like a medium patch.
- Feather and repeatOnce it's dry, add a second thin coat that's wider than the first. Thin and wide beats thick every time.
- Sand, prime, paintSand lightly until you can't feel the edge with your fingertips. Prime before painting, or the patch will show as a dull spot. Shine a flashlight across the wall afterward; if you can't see a shadow at the edges, you're done.
Watch it done
- You can't feel the patch edge with your fingertips
- A flashlight shone across the wall shows no shadow at the edges
- The painted patch doesn't show as a dull spot
- No raised bump where the hole was
If the patch shows
Can you see the patch through the paint? That's usually from skipping primer. Bare compound absorbs paint differently than the wall around it.
If the patch looks like a raised bump, feather it wider. Add a thin coat that reaches 3 or 4 inches beyond the edge and sand it smooth. To match textured walls, use spray-can texture after sanding.
What a pro typically charges (a rough estimate; prices vary by area): A handyman typically charges $100–$300 for small drywall patches, including paint touch-up.
