Primer question....need answer ASAP. Thanks!
My husband is painting primer over new drywall (an entire house remodel), and the Sherwin Williams product we're using is not covering very thoroughly. Is it necessary to put on a second coat before applying our actual paint?
I know you're always supposed to prime the walls, but I'm not sure the exact reason for doing so, so I don't know how important it is to have a good solid coat of primer.
