I have found that Dulux plaster seal is an excellent product for new plastered walls. Goes on light blue but dries clear (its withcraft I tell you!), but seal the wall before painting. Seems to need less wash coats before getting a good finish rather than the first few soaking into the plaster.
Erm, if you use a plaster sealer you don’t really need wash coats but you need one or the other soaking into the pores in the plaster surface, it’s what key's the paint to the plaster & makes it stick! If the paint doesn’t key to the plaster, it will eventually bubble & even fall of at the slightest excuse; & if you (or some other poor soul) ever stick wall paper over it, the paint will come of in sheets on the back of the paper the first time you strip it!
Yes I meant seal with the plaster sealer and yes this seals the wall for the painted coats. When I said less wash coats maybe I used the wrong terminology not having got a degree in painting and decorating, but I meant, and I thought it was pretty clear from my reply, that you'd need less coats of paint and so saves time between painting them.
I did; because if new plaster isn’t correctly primed the paint won’t stick but this may not be apparent until wallpaper subsequently applied is stripped off, taking the paint with it!
As I’d already posted; this is a duplicate post which the OP had already acknowledged & there is detailed info on the other thread. I was concerned that your post wasn’t clear & the OP may get it wrong & merely asking you to clarify. No need to tetchy fella, the rollies aint necessary
