1
Cutting the damaged section

  • 1.1Using a stud finder, locate the studs on either side of the hole.
  • 1.2Using a square, outline a rectangle around the whole. The size depends on how big the hole is.
  • 1.3Cut around the outline with a utility knife.
  • 1.4Remove the section.

Using the square as a ruler ensures a straight line without having to change tools.

2
Reinforcing the sides

  • 2.1Cut 2 reinforcement pieces. They should be 4 to 5 inches longer than the cutout. If there are no studs in the area, cut 2 support boards using at least ½" wood.
  • 2.2Place the first reinforcement piece in the hole and hold it in place. Put the board at the top of the cutout so it’s half hidden by the panel.
  • 2.3Screw the beam at the top and bottom of the cutout using 2½" drywall screws. The screws should be placed at an angle.
  • 2.4Secure the second beam the same way.

If your studs are more than 16" apart, cut the wall and support beams to fit the measurements.

3
Filling the hole with a piece of drywall

  • 3.1With a utility knife and a square, cut a piece of drywall with the same dimensions as the cutout.
  • 3.2Place the drywall in the hole and screw each corner to solidify.

If the cut piece of drywall doesn’t fit into the hole, shave the sides until it fits properly.

4
Finishing the repair

  • 4.1Cover the sides of the patch with drywall compound. If the gap around the drywall is too big, use joint tape.
  • 4.2Apply a coat of drywall compound onto the joint tape. Let dry overnight, sand, and apply a second coat.
  • 4.3Sand the joint with a medium grain sandpaper, repaint the wall if needed.
