Can I put drywall compound on a painted, textured wall?
We've got some irregularities on our walls (of drywall) that would look better if the dents were filled a bit, and seams were feathered out better. However, the wall is already painted and heavily textured. My husband thinks we've got to totally sand the area smooth before we can apply the joint compound to the depressions and seams. He says the compound won't adhere to the painted surface.
I think we should be able to fill in on the existent surface and then retexture, prime, and paint just the affected areas.
Can we do that, or is my husband right in thinking the compound will simply fall off the painted walls?
