How to repair holes in drywall
Get a ready-made drywall patch.
These are available at big-box home centers and hardware stores. They use a peel-and-stick, metal-backed patch for added strength.
If the hole was caused by a door knob or another object hitting the wall, a patch may hide the hole but it is not strong enough to hold up to another impact. Patching with a new piece of drywall will be a better solution.
