Does Bare Drywall Need to Be Primed

Bare drywall, where the taped and mudded seams and fastener holes are still exposed, requires priming before painting. … If you do not prepare the surface, you may find yourself applying too many coats of paint before the mudded seams stop showing through.

Is priming new drywall necessary?

Do you always need to prime drywall before painting? It’s important to prime after new drywall installation. The new surface will be porous and will absorb the color of the paint. Primers will also cover the joint compound and provide a good base for texturing or painting over skim-coated drywall.

What happens if you don't prime before painting?

If you skip priming, you risk peeling paint, especially in humid conditions. Moreover, the lack of adhesion could make cleaning more difficult months after the paint has dried. You may find the paint wearing off as you’re trying to wipe off dirt or fingerprints.
