Drywall repair is intimidating to many. What if you screw up? Then you’ll have to have the whole wall redone! Better to just hang a picture over that ugly, unsightly crack. But what if you could do it yourself? What if it were easier than you thought? Well, it is. Just follow the simple steps below.
How to cut drywall:
- Measure and mark your drywall where you plan to cut it.
- Using a straightedge and a utility knife, cut through the paper on one side of the drywall. Don’t put too much pressure on the utility knife. Make several passes until you are through.
- Bend the drywall back on itself to break through the gypsum interior.
- Turn the drywall over and cut through the paper on the opposite side.
How to patch a small crack in drywall:
Step 1: Prepare the surface by cleaning out the crack – remove all dirt and debris from the area and make sure it’s completely dry before you get started. Now sand the surface around the damaged area using medium grit sandpaper (100–150 grit). This sanding provides a good base for the joint compound and smoothes out any texture you may have on the wall.
Step 2: Apply the patch. Method 1: Apply the joint compound with a flexible putty knife or spreader by working across the crack with strokes in both directions, working it into the crack. Method 2: Apply mesh drywall tape with adhesive backing over the crack. Apply a thin layer of joint compound over the tape. Feather the edges of the compound using your joint knife or spreader.
Step 3: Finish. Use the putty knife as a scraper to remove any surplus material. Move it along the cracked area gently to scrape away any extra material. When the material is completely dry, sand the area and prime it for a coat of paint or other finish.
