From doorknob dents to nail holes to fist-sized accidents, drywall damage is inevitable — and almost always repairable without replacing a whole sheet. This post covers the three repair sizes: tiny holes (spackle and sand), medium holes (mesh patch and joint compound), and large holes (a backed drywall patch). We also share the trick most people skip: feathering the compound wide and sanding between coats so the repair disappears under paint instead of standing out as a bump.
