PVAing the plaster is a fashion without need. Paint onto bare dry plaster results in the liquid in the paint being sucked into the plaster, leaving it short of glue, hence the peeling. Solutions:
a) 50/50 diluted ****coat first
b) paint the plaster with water, wait 5 minutes then paint as normal.
c) dilute PVA onto plaster first. Too much and you get slicks paint won't stick to.
I prefer B, it's quicker & stronger. C I'd avoid.

D) plaster sealer

Sure, you can always be a mug.

Just as well reasoned as ever ;-)

One only need look at the prices to see the reason. Plaster sealer is simply not needed.
