How to Repair Drywall Holes and Cracks

Drywall damage is inevitable. A doorknob punch, a shelf that came loose, settling cracks in corners—they all look worse than they are to fix. The real skill isn't in the repair itself; it's in understanding that drywall finishing is a patience game, not a speed game. You'll apply compound in thin layers, let each dry completely, and sand between coats. Done right, the patch vanishes. Done fast, you'll see it every time the light hits that wall.

1. Scope the Damage First. Identify whether you're dealing with a small hole (nail-sized to 1 inch), medium hole (1–6 inches), or crack. Use a putty knife to scrape away any loose paper, crumbling drywall, or paint around the damage. For cracks, cut away any raised or peeling tape. Wipe the area clean with a damp cloth and let it dry completely.
2. Press Spackle Deep Into Holes. For nail holes and small punctures up to about 1 inch, apply lightweight spackling compound directly into the hole using a putty knife. Overfill slightly, pressing the compound into the hole so it's flush with the wall surface. Smooth it level with the wall, feathering the edges outward. Allow to dry per the product instructions (typically 1–3 hours).
3. Mesh First, Mud Second. For holes 1–6 inches, apply a self-adhesive mesh patch directly over the hole, pressing it down firmly so it adheres completely. The mesh acts as a reinforcement base. Cover the entire patch with a layer of joint compound using a 6-inch putty knife, feathering the edges outward 2–3 inches beyond the mesh. Let dry completely (typically 4–8 hours).
4. Tape the Crack Down. Clean out any loose material from the crack with a scraper. Center a strip of drywall tape (typically 2 inches wide) over the crack, pressing it down firmly. Apply a thin coat of joint compound over the tape with a putty knife, covering the tape completely and feathering 4–6 inches on either side of the crack. This is your first coat. Let dry completely.
5. Layer Thin Coats Wide. Once the first coat is dry, sand it lightly with 120-grit sandpaper to smooth any ridges. Wipe away dust with a damp cloth. Apply a second coat of compound, this time with a wider putty knife (8–10 inches), extending the feather zone another 2–3 inches. Let dry completely. Apply a third coat if needed, using an even wider knife to blend seamlessly into the surrounding wall. Each coat should be thinner than the last.
6. Feather Edges Into Oblivion. Once the final coat is completely dry, sand the entire repair area with 120-grit sandpaper, then finish with 220-grit for a smooth, seamless surface. Sand in circular motions and feather the edges so there's no ridge where the patch meets the surrounding wall. Wipe away all dust with a damp cloth and let dry.
7. Primer Seals, Paint Blends. Apply a primer designed for drywall repairs to the patched area. Once dry, apply two coats of finish paint, using a brush or small roller to blend the repair into the surrounding wall. You may need to paint the entire wall if the repair is large or near the center of a wall face.
