Is the plaster sealer sold in bottles and tins, eg B&Q Interior
Plaster Sealer, just an expensive way of buying water with a bit of
PVA mixed in? Couldn't I just use say a 1:3 PVA:water mix? Would one
coat be enough on new plaster before painting?


I recently coated a whole, newly-plastered house with 1:4 PVA at the behest
of the plasterer, and it was a disaster. It rendered the surface
impermeable, sort of non-stick, and the newly applied emulsion could be
scraped off with fingernails after it had dried. Next time I'll use
diluted, cheap white emulsion as I always have in the past.

Why do we have to do this anyway? I've just had new french doors fitted
to the lounge and have never painted over fresh plaster before.
Unfortunately I was halfway through painting the new plaster before I
remembered most people apply dilute emulsion to seal it. I still have
the rest of the new conservatory to paint so will go the dilute route
with that, but the small bit I did with full strength emulsion seems
fine - so why use dilute at all?
