How to Patch Drywall

1
Outline the Damaged Area with a Carpenter’s Square

  • Using a carpenter’s square and a pencil or marker, draw a line at least an inch or more above and below the damaged area.
  • Use a stud finder to find the nearest stud on either side of the hole and mark those.
2
Cut the Sides with a Keyhole Saw or Utility Knife

  • Use a saw blade or utility knife to cut along the lines you just drew. When you run into a stud, mark and measure a 3/4 inch farther in, which will be the center of the stud. 
  • The edge of the patch should be directly over the stud so both the existing drywall and patch have support. 
  • Cut along the lines carefully, making several passes with each cut slightly deeper than the previous cut. 
  • Remove the damaged piece of drywall.


Safety: Cut away from your body, not towards yourself.

Cut the Support and Install in the Wall

  • Cut a 1 x 3-inch piece of scrap lumber or 3/4-inch piece of plywood approximately 2 to 4 inches longer than the height of the patch. 
  • Screw these supports vertically behind the opening to keep the patch from cracking. 
  • Hold the support in place and secure it with drywall screws without driving the screws through the drywall.

Cut the Drywall Patch to Size

5
Install the Drywall Patch with Drywall Screws

  • Position the screws at least an inch from the edges to avoid spitting or crumbling the drywall. 
  • Use a drill to affix the patch in place.
6
Complete the Drywall Patch

  • Run strips of self-adhesive fiberglass drywall tape around the patch, centering the tape on the seams. 
  • Use a 6-inch drywall taping knife to spread drywall joint compound across the patch and tape to create a smooth, flat surface. 
  • Let the compound dry overnight, and then sand until smooth. Repeat with a second coat. 
  • For a very smooth drywall hole repair, spread a third coat with a 12-inch drywall taping knife and let dry overnight, then sand, wipe with a tack cloth and paint the area.
