The short answer
Under 1 inch: filler and sand. 1–6 inches: self-adhesive mesh patch, two thin coats of compound, sand, prime, paint. Over 6 inches: cut a square, back it with wood, and fit a new drywall piece.
The difference between an invisible repair and an obvious one is thin coats and feathering, not skill.
Step by step
- Clear loose paper and crumbling edges with a utility knife.
- For small holes, press filler in, slightly proud, and let it dry fully.
- For medium holes, apply a self-adhesive mesh patch over the hole.
- Skim a thin coat of joint compound over the patch, extending 3 inches past the edge.
- Let it dry, then apply a second thin coat extending 6 inches, feathering the edges.
- Sand with 120 then 220 grit until you cannot feel the transition with your palm.
- Prime the repair — unprimed compound flashes through paint.
- Paint two coats, feathering into the wall.

Common questions
Why does my patch show through?
Either no primer, or the compound was not feathered far enough.
How long between coats?
Standard compound needs 12–24 hours. Quick-set powder needs 30–90 minutes.
Can I paint straight over filler?
It will look duller than the surrounding wall. Prime first.
