Obtain the recommended tools to get the job done properly include: drywall screws, drywall saw, screw gun, shop vacuum, straight-edge, step ladder or stilts, stud finder, T-square, utility knife, sanding sponges, mesh drywall tape (for joints), regular drywall tape (for corners), joint compound, safety glasses.
Be sure that you are using the appropriate type of drywall for the job. Some common examples and their uses are:
High strength light-weight drywall is appropriate for ceilings
XP board is required for moisture-resistance and is applied to wet walls in bathrooms
Type X drywall has added fire-resistance for walls
Regular gypsum is commonly used in homes and commercial spaces where no added protection is needed
Plan to utilize the longest and largest sheets of drywall possible to avoid creating unnecessary joints that will need to be taped and sanded.
Checking cut sheets for electrical boxes and other openings prior to securing the drywall tight to the metal frame will help you avoid spending extra time patching and finishing.
Only sand the joint compound/mud or you will rip the gypsum and the wall will feel and look rough and textured when painted. Try practicing on a scrap piece of drywall before sanding a sheet that has already been installed.
After completing sanding, run your hand down the length of the wall to ensure joints are as flat as possible. Drywall can be tricky so just using your sense of sight isn’t always enough to guarantee perfection.
Before the final coat of paint is applied, point up (also known as touch up) in permanent lighting for one last chance to repair any imperfections.
