If you’re installing new drywall, you may need to skim coat the drywall first for a smooth finish and to allow the primer to adhere to the wall. It’s only necessary if there are imperfections in your drywall due to issues with the studs or improper drywall installation. If you’re refreshing existing walls, you may want to skim coat if there are imperfections across the wall. As an alternative, you can repair your drywall and sand it for a smooth finish before painting.

You should wait at least 24 hours between each coat of drywall mud before sanding and adding another coat. This ensures the mud dries completely, although drying time depends on temperature, humidity, and the type of compound used. Lightweight muds dry faster, while heavier all-purpose compounds take longer. Always check for firmness and dryness before sanding or applying the next layer.

Most drywall used for interior walls of homes is 1/2-inch thick. This size strikes a balance of being easy to handle and hang while being thick enough for the durability needed on interior wall applications.

The easiest way to cut holes in drywall for electrical boxes is to use a spiral saw with a drywall router bit. Hang the drywall without cutting out a hole for the box, but make sure you measure and mark where the box is located on the wall. Once you screw in the drywall sheet, drill a small hole into the box void, insert the spiral saw bit, and move it around the edge of the box using the inside wall as a guide. You can also use an oscillating multi-tool with an electrical box cutout for fast, professional results.
