>Fixing a Hole in DrywallDrywall might look thick and strong from the outside, but it's incredibly fragile on the inside. You can easily put a hole through your wall just by bumping into it with the sharp end of your coffee table. The good news is that fixing a hole in your drywall is fairly simple and inexpensive. Regardless of your level of construction experience, there are a few simple steps you can follow to patch up a small or moderate-sized hole in your wall in no time. All of the supplies you need are affordable and easy to find at any home improvement store.Because drywall typically breaks off in irregular pieces, chances are that the hole in your wall is going to have a jagged shape. Working with an irregular shape is difficult, so it's a good idea to even it out before you get started. Use your ruler to draw a rectangle or a square around the hole. Cut the new shape out with a drywall saw. After you remove the drywall, go over the edges of the new hole with a utility knife to soften them. Home improvement stores carry backer boards in a variety of sizes, so you can easily find the best size for your needs.Don't worry if the hole is too big to be covered by one backer board. You can use a couple of backer boards if you need to. Attach them to the back of the drywall with a screwdriver. After measuring the hole, cut out the right dimensions from a new piece of clean drywall with your drywall saw or utility knife. Use drywall screws to secure the new piece into the hole. Cover the patch and the surrounding area with mud. Use a few coats if necessary.Put drywall tape on top of the mud. Make sure that the tape is flat and even. After you are done flattening the tape, cover it with two more coats of mud. Once the third coat of mud is dry, sand it down until the area is completely smooth. Besides a difference in color, the new patch should blend in perfectly with the rest of the drywall. All you have to do now is paint the area with a matching color, and your wall should look as good as new.
