Even if you aren't handy around the house, you can easily patch drywall like a pro. How to patch a hole in drywall is a simple task. Most drywall repair consists of fixing dents, nail and screw holes, cracks and popped nail heads. This type of damage is minor and can be fixed quickly and easily.
You can save a lot of money by installing drywall yourself, but it's not usually a job for a DIY newbie. The cost of purchasing the panels (without the additional labor and finishing costs) is around $0.40 to $0.65 per square foot, so about two-thirds less expensive than professional installation.
It's fine to fill screw holes and other small wall dings with patching compound, but for dime-size and larger drywall repairs, and for holes that are deep, it's best to use a joint compound that sets up by a chemical reaction. These are available in powder form with setting times ranging from five to 90 minutes.
Patching drywall requires you to cut a clean hole in the wall, cut a patch to fit, screw the patch into place on the wall and tape around the joint before mudding. It may seem counterintuitive to cut a bigger hole in the wall, but it is the only way to get a strong, smooth finish in the end.
