OK. We redid our powder room. All new drywall. We wiped the dust off of the walls prior to priming with towels. Used many towels until no more dust was showing on the walls and the towles were no longer "dusty". I was afraid to use a damp rag over the bare joint compound. Primed the drywall with a primer/sealer. I found some imperfections in the wall after priming. After a few days (3-4) I marked these spots with a small pice of blue painters tape. When taking the tape off, it blisters and pulls the primer off of the wall. Mainly on the areas where the joint compound is. The rest of the wall I did "spot checks" and it seemed OK. Is the primer not "cured" enough for the tape yet? Willa nother coat of primer help it adhere to the wall?
