Is it really a must to skim over PVA only when tacky? even after sealing the walls / ceilings with 2 coats of PVA earlier that day or the afternoon before? surely once you have sealed & killed the suction its ok to skim wheather its still tacky or has dried. I do this & have had no probs & pulls in lovely. 2 water x 1 PVA ratio
