Holes up to a couple of inches across can be easily repaired. Pin holes can be repaired with a bit of joint compound or filler putty. For larger holes, use the technique shown below, or purchase a repair patch at a hardware store or home center. These patches consist of self-adhesive metal or fiberglass mesh that can be used to bridge the hole and support the joint compound.
All You Need
Time: 20 to 30 minutes of actual work, plus drying time.
Skills: Intermediate skills, particularly for getting a smooth finish on the repair.
Tools: Taping knives, keyhole saw or drywall saw, hammer, drill, utility knife, sanding block or sponge, paintbrush.
Step-by-Step
Pinholes

For very small holes, apply joint compound to the void with a putty knife. After drying, sand smooth.
Larger Holes
1. For larger holes, cut pegboard slightly larger than the hole, but small enough to fit through the hole. You'll use this as a backing for your patch.
2. Fasten the backing to the wall
Tie wire to it, smear compound on hardboard, and slip into wall. The backing will cling to the inside surface of the wall.
3. Secure the backing.

Tie wire to a pencil and twist tight. After patch dries, cut the wire off and fill the recess with compound.
4. Finish the patch.

Fill with two or three thin coats of compound, lightly sand, and sponge to blend repair. Prime and paint.
