How to Fix Drywall Holes
Drywall can only withstand limited abuse. If you open a door with too much force, it can hit the wall and drill a doorknob-sized hole in the drywall. This type of damage looks bad but is easy to fix. The easiest thing to do is to buy a drywall repair kit. Measure the hole and visit your local hardware store or home improvement center for a kit, or buy one online. There are different sizes and types for different uses. For example, a drywall patch for a ceiling is thicker than one for a wall. Before using the kit, remove any loose paper or plaster of paris from the edges of the hole. Then apply the drywall patch according to the manufacturer’s instructions.
This article will teach you how to repair both a small and a large drywall hole. We start with a small hole.
Repair a small hole
Follow these instructions to repair a small drywall hole (about 6 inches) without a kit:
The first thing you need to do is get a piece of drywall that is the same thickness as the drywall that you need to fix. If you don’t have one at home, a hardware store has smaller parts that you can use. You don’t have to buy a whole sheet.
Measure the patch. It should be big enough to cover the hole and a few more. Give yourself plenty of leeway – about two inches on each side of the hole. You don’t want the patch piece to be too small. Next, cut the patch square out of the larger piece. Turn the plaster over and score the paper with a straight edge with a utility knife about an inch from each side. Don’t cut all the way through the paper or plaster of paris. Next, loosen the loose drywall, but leave the loose paper on the back. Place the plaster over the hole in your wall and draw it around the plaster of paris with a pencil (don’t include the paper when tracing it).
Let’s clean up the hole in the wall. If you have a drywall saw, bully for you. This is the right tool. If not, don’t worry. You can use this utility knife. Whichever blade you use, cut diagonal lines starting from the hole to all four corners of the outline you just drew. This creates a nice square opening. (You don’t have to cut diagonally to the corners, although it is easier. Just cut out the damaged portion of the drywall.) If you are cutting diagonally to the corners, you will also need to notch the outline of the square with the utility knife. After the notch is done, snap back the drywall, cut the edges with the utility knife, and pull the drywall out so you have a nice, clean square hole.
Next, turn the patch piece face down and use a spatula to apply a thin layer of grout to the back of the paper. Flip the patch over. Place the patch over the hole and press the edges of the paper. Make sure it is securely in place. The grout holds the pavement in place.
Finally, apply grout to the pavement with a spatula and spread it on the wall. Two or more layers of interconnection may be required. It spreads easily and is fun to work with. When the mixture dries, sand it smooth with a fine-grained piece of sandpaper. The patch is intended for priming and painting.
