Lee007,calm down dear,it's only a forum.There is no need to SHOUT. What are you trying to say.Have you just plaster-boarded something,say,a wall or a ceiling,and then plastered over it? Oh God, now you've realised you put PVA on the boards,(2 coats) and you wonder if it did any good....... I wouldn't put PVA onto new plaster-board personally,but if you have,and you plastered onto it while it was still wet and tacky,no problem.
