The Importance of Preparing Drywall For Paint
Preparing the drywall for painting is one of the key steps in professional painting. Here are the benefits of prepping drywall for paint:

How To Prep Drywall For Paint?
Fill any holes and cracks in the drywall with a filler and sand once it’s dry. Make sure the filler is compatible with the type of paint you’re using. Wipe the surface of the drywall with a damp mop or cloth. Use a liquid primer before painting; a liquid primer will prevent the drywall from absorbing paint. Typically, one coat of primer is sufficient, but you can apply a second coat after the first has dried if you wish.
