I've never painted onto fresh plaster before, I've had some insulation put on the conservatory walls. It's then been plaster-boarded then skimmed, it's all gone a nice pink colour, so fully dried out.

I did not know this but I'm told I need to 'mist coat' the walls first? Say 1 cup of paint to 4 cups of water?

It then needs 3 or 4 coats, is this the best way?

Cheers in advance

Either watered down cheap emulsion or PVA watered down will do the job

Thanks 

Got some No-nonsense brilliant white from ScrewFix, couple of 10L ones for £25. So was planning to water that down a bit in a bucket 

I do have some PVA in the garage, from when I did the floor there. Although I think I would prefer watered down emulsion, less sticky!

Stick the lot in a bucket and get splashing

nice pink colour

Should be more of a whitish pink when fully dry

How long has the plaster been up, this time of year needs extra time to fully dry.

It's been up 9 days now, I'd say it's more a salmon pink? I've had the windows open for most of the time. Might leave it another day or so

Depends on how much it was polished tbh
After 9 days should be pretty much there by now so I would shut the windows and just get a bit of warmth into it to finish it off 
Look at splashing paint around Wednesday

You need the watered down emulsion to seal the plaster. It will suck it up like a good 'un, but that is what you need. If you try putting neat emulsion on, it will only sit on the surface and will be hard to apply, and may cause problems later, if you ever decide to paper.  Plus a probable uneven coating. In all my years in the trade, we never used 'plaster sealer' just cheap b and q matt emulsion.
Theoretically, its best to use a non vinyl emulsion to seal the plaster. Vinyl Emulsion seals the 'pores' and does not let the emulsion 'breathe', just in case it is not fully dry underneath.
Mind you, in todays high speed world, I don't suppose a lot of so called 'decorators' give a toss as to what they put on.!!!! You would have been shot at dawn in the olden days for not using non vinyl as a sealer

60/40, cheapo emulsion n water it's called a mist coat.

Cheers chaps 

Looking forward to getting this job done

Just to echo what others have said, we've done about 6-8 rooms in our house over the past 2 years, for insulation reasons like you. We watered down the cheapest emulsion we could get so that it was about the consistency of full fat milk.

If you've had skim over plasterboard, it can be dry in 3 days, if you've had a thick coat of "browning" onto brick with a skim over, it takes about a week. The way to tell is it gets lighter as it dries. Once the colour stops changing, you're ready to paint .


I would also use the same watered down emulsion if wallpapering, otherwise the walls can such the moisture out of the paste too quick and cause the paper to bubble/shrink.

Oh and as a heads up, I'd expect some minor (1-2mm) shrinkage cracks in the corners of rooms. So if you have the scrag-end of a pot of emulsion left, don't bin it

Can also use any masonry paint, directly applied to the plaster as that stuff is 'breathable' and you can get it non textured too, and in almost any colour you wish too...

We used to put a dollop of union bond in a bucket of water, splash it on, the suction of the new plaster meant you could more or less paint it straight away.
