In my opinion, no. Never heard of PVA added like that before. Personally id be concerned if PVA was applied to newly plastered walls. Best to start with a mist coat then a very light sand then a second mist coat.

all u need is a base coat of water based paint (emulsion) just to seal the wall, if u roller on then wat ever u put on over the top wont have brush marks
