Water Damage Repair - Drywall Repair How To

Medium Hole Repair (3-4 inches)
1.Outline the damaged area with a framing or carpenter's square. Then use a drywall knife, jabsaw, or utility knife to cut away the damaged section of drywall making a rectangular/square shape.

2.Cut the patch from a new piece of drywall that measures about three inches larger than your hole on all sides.

3.On the backside of the drywall outline your hole on the center of your piece. Very carefully remove all the rock material from the back around the area you just outlined leaving the paper on the front.

4.The solid piece of drywall should fit in your hole with a few inches of overlapping paper. Cover the patch with spackling compound or drywall compound, and then smooth the entire area using a wide blade drywall knife. Let the patched area dry. Lightly sand the area smooth using high grit sandpaper. The area can be wiped with a damp sponge to eliminate the dust normally caused by dry sanding. Apply additional coats of compound if necessary, lightly sanding after each coat.
