Misgrace is right. Use a thinned down vinyl matt emulsion as your mistcoat. This will seal the plaster and enable subsequent coats to adhere. PVA is also an option. Again thinned out. Some decorators use the mistcoat and some use PVA. There are no hard and fast rules. The mist coat is a cheaper option. You should only paint once the plaster has gone completely light pink and there are no obvious damp spots. I allow between 5 and 7 days for it to dry.

Thanks phil,:D I meant to have said you can mistcoat new plaster using a vinyl paint, but preferably on a skim coat of plaster, if its gone back to the brick, and it has bonding plaster, followed by a skim, then you should use a non vinyl matt, never silk, soft sheen, and me personally would never use PVA as a sealer on any plaster, I know some decs do, thats thier choice, but I know a 100% that if I use contact matt (non vinyl) there will never be any comebacks.
I even use it on skimmed plaster, admittidly I have used vinly in the past on skimmed plaster, but had a little comeback, maybe I was unlucky, but just to be on the safeside I wouldnt do it again.lol

I agree about the 5-7 days for the skim plaster to dry, sometimes it can dry out in 3 or so days, depending on the weather, but just give yourself at least a week.:D

I'm decorating a house now, that every room is new skimmed plaster, the ceilings are going in white, and the walls magnolia, so I will be coating the ceilings and walls with the contract paint, then doing a finish coat with a washable vinyl mat.

Its a hell of a lot cheaper is you buy say for example a 10 ltr tub of gliddens contract, which works out including VAT approx £15-£16 a tub, and it goes really far.:D

He put lining paper on a freshly plastered wall to make it look better?

I thought that was strange, unless the plastered walls were badly plastered.
