I put a chair through the wall. Not on purpose — I was moving furniture, misjudged a turn, and the leg punched a fist-sized hole right through the drywall. My security deposit flashed before my eyes.

I had never patched drywall before. I watched three YouTube videos, bought $18 worth of supplies at Home Depot, and spent a Saturday fixing it. The result was invisible. My landlord never noticed. Here is exactly what I did.

What You Need

A drywall patch kit costs about $10 and includes a mesh patch, joint compound, and a putty knife. You also need sandpaper — 120 grit is fine — and matching paint if you have it. If you do not have the original paint, chip off a piece the size of a quarter and take it to any paint store — they can color-match it for free.

The Process

1. Clean the edges. Use a utility knife to trim loose paper and jagged edges around the hole. You want a clean, smooth border.
2. Apply the mesh patch. Peel and stick it over the hole. The adhesive is strong enough to hold but do not stretch it — just lay it flat.
3. Spread joint compound. Use the putty knife to spread compound over the patch, feathering the edges outward so it blends into the surrounding wall. Do not try to make it perfect on the first pass — this takes two or three coats.
4. Let it dry completely. At least two hours, ideally four. If you sand wet compound, it smears instead of smoothing.
5. Sand smooth. Light pressure, circular motion. Feel the patch with your fingertips — if you can feel the edges, it needs another coat.
6. Paint. Two thin coats, feathering the edges into the surrounding wall.

The whole thing took me about three hours of active work spread across an afternoon. Most of that time was waiting for compound to dry. The actual labor was maybe 45 minutes.
