Intall drywall

Step 1

Before beginning, use a flashlight to check inside the hole for any studs, plumbing or electrical wires that would interfere. If clear, use a keyhole saw to square off the small hole in your wall so that it’s easier to fit the patch. Measure the opening.

Cut a new piece of drywall that is two inches bigger than the opening on all sides.

Step 4

Snap off the outer gypsum area and peel it from the paper backing, leaving the “wings” that will be adhered to the wall in the next steps.

Step 5

Hold the patch over the opening. If it doesn’t fit in the opening, trace the remaining gypsum around the opening on the wall with a pencil and cut to fit. Once it fits, trace the outer flaps onto the wall.

Step 6

Score the wall and remove just the paper of the area marked around the opening. This will allow the patch to lie flat in the wall.
