A new coat of paint, especially in an eggshell or satin finish, catches light and shows every dent, crack, and patch on the wall. That's why drywall repair comes before painting.
Nail holes and small dings are the easy ones. They're filled, left to dry, and sanded flush.
Nail pops, where a drywall screw or nail pushes back out of the wall, are common in newer homes as the framing settles. The fastener is reset, a new one is added nearby, and the spot is filled.
Bigger holes, like the classic doorknob hole, need a patch of new drywall cut in, then taped and finished in thin coats of joint compound. Each coat is sanded before the next one goes on.
Water-damaged drywall is cut out entirely, after the source of the leak is fixed, and replaced with a new section.
Every repair is primed before painting so it doesn't flash through the finish coat. Call RNA Pro Painting at (704) 649-4940 for a free estimate on drywall and painting.
