First coat on new plaster?

[Brenn]

Recently had my kitchen reskimmed and a new plasterboard ceiling,
What do people use for the first coat?

I've heard some say watered down emulsion or an off the shelf product.

you can get a big 10lt tub of crown emulsion from BQ for around £13. Just use that, great coverage too as I've just used it on a job. (up to you if you want to water it down)

I usually give the plaster a rub with fine paper to remove any nibs, then paint a mist coat, 50/50 matt paint & water, allow to dry throughly then a couple of coats of paint.

You can use vinyl silk as a mist coat, but I'm old school & prefer to use matt.
Also some of the cheapper emulsions are rather thin, so you don't need so much water.

Been Wickes White Trade matt emulsion found it very good.

This link show the difference using neat paint & water down paint on plaster.

50 50 pi55 coat

Don't use pure emulsion it could peel off in sheets

Thanks guys

Will the angle beading on the corners need treating with anything different?

You need to water down contract matt to the consistency of thin cream. Give it a coat, look for imperfections, easifill and sand where needed (sockets are usually the issue) spot prime the filled areas with more mistcoat. Then full coats.

Angle beading? You can use some Zinsser BIN there, or even oil based undercoat to stop any rust staining issues.

Don't stick any PVA near it and make sure you dilute sufficiently or it'll just suck all the water out of the paint and skin over.

I've always used a thinned coat of matt paint first as well.

I remember a mate of mine that didn't, going straight on with a coat of un-thinned silk emulsion. A week later he masked the walls off so he could paint the ceiling and removing the tape peeled off a 2"wide strip of paint from the walls

I've never had that problem using thinned matt first

We did our whole house using a base coat of cheap B&Q value emulison watered down, not 50/50 as that stuff is mostly water anyway and haven't had any issue with peeling.

I thought long and hard about sanding down and spot fixing and decided it was going to take far to long and drive me mad for something that long term I wouldn't notice and 8 years on I'd say it was a good choice even I don't notice the bits that I know are dodgy.

A lot depends on the plaster & how good he finishes the plaster.

The first coat is on got a very large tub of crown emulsion from B&Q while they had it on offer.

Not one dimple on the plaster as the guy that did it came over and gave it a rub down whilst I was on holiday.

Definitely this, ive had to complain to a builder we do a lot of work for about the quality of the plastering lately. Very poorly finished, full of lumps and scratches, and also the skim coat seems powdery in parts. When coated with watered down emulsion you can see an awful lot of trowel marks in it. On one house lately we had to base coat the walls with very thin paint then sand entire rooms with foam block sanding pads to level them out.

Many years ago I did some work for a friend, there were three walls to plaster, she threw the plaster off the job.

We had a kitchen from Germany coming in about six weeks, I was unable to find a plaster at short notice,& years since I plastered, but no choice, mixed up first batch, then her mother & grandfather turned up.
Old chap was really ******* me off in nice way, about my plastering style, I down tools & went & made a coffee, came back to find a 90 year old, jacket off & plastering, he been a plaster all his life, started the trade with his father when 10, it was a honour to watch a true master of his trade, the speed & the quailty of finish was impressive.

I leant a lot that day.

this - plasterer left the place looking like walls of glass - not a mark on them. 1 coat of cheap B&Q emulsion, left to dry and then paint over that.

Nice un, it does show you how the old guys still know whats best. A very good friend of mine is an excellent plasterer, but he's getting on now and suffers from severe back pains. Any house he ever done was a pleasure to work on. Luckily mate when i served my appreniiceship i was taught by a 38 year veteran, that was 20 years ago this month, (crikey, im getting old lol).
