How to Fill a Hole in a Drywall Ceiling . Perhaps you made yours while moving a ladder or a tall bookshelf, or maybe your son did it while fielding high- fly balls. Small holes are the easiest to patch - - some patching compound and joint compound is all you need. To patch larger holes, you'll need a piece of drywall and some scrap wood. The procedure may take a few days, but there's nothing complicated about it. You'll be on a ladder, so make sure it's high enough for you to work safely. Small Holes. Mix enough patching compound with water to fill the hole. You can find patching compound at the hardware store.

Let the patching compound set for an hour or until it turns dark yellow and is hard to the touch. Cover it with drywall joint compound and scrape the joint compound flat with the 4- inch scraper.

Drive a drywall screw partially into its center. Set the wood into the hole with the screw facing out, then grasp the screw and use it to pull the wood down while you drive 1 1/4- inch drywall screws into the edges of the drywall and through the wood to hold it in place against the back of the drywall. Once the wood is secure, remove the central screw. Place the drywall patch in the hole and screw it to the wood. Cover the edges of the patch with drywall mud, using a 4- inch knife, and lay paper drywall tape on the mud. Scrape the tape flat with the knife, then lay a second coat of mud and scrape that flat.

Drywall joint compound. Drywall primer. Ceiling paint. Paintbrush. Scrap drywall. Drywall saw. Scrap 1/2- inch plywood or lumber. Paper drywall tape. Tip.
