Unlike a small hole in drywall where you need only cover the hole with an adhesive mesh / metal drywall patch, holes larger than 8 inches are going to be patched with a piece of drywall. The area receiving the patch will need to have the edges made neat and clean to prepare for the installation of the wallboard patch.
- Using a straightedge, or preferably a framing square, mark off the a square or rectangular section around the large hole or damaged drywall area.
