Painting Coated Drywall
Can the drywall be painted if the plastic is roughened up and properly primed, or am I wasting my time and should just tear out the old material and replace it?
Visit a good paint store (which can include a local Home Depot, as long as you get an experienced person). Have them determine what primer you need. That will determine how you must prepare the existing surface.
Would you be kind enough to let me/us know what kind of primer is recommended? That way we'll know for next time. Thanks.
