Right, stripped the crappy paper off the bedroom walls. Its revealed nice fresh plaster coverings on all walls that have prob only been done within the year, we moved in July and the previous bloke only had it a year.
Wanting to paint but unsure whats best to do:
The plaster has only had a slight whitewash in places, other parts are not coated. Therefore do i need to precoat it first with a water/paint solution before emulsioning, or
It it better to put up lining paper then paint that?
Thoughts

I water down some paint and put it on bare plaster.
I came across some when I was repainting the lounge recently.

Just finished this on a fully refurbed house.
Depends how much time you want to put into this..
Fresh plaster - pva/water mix or whitewash - this is you choice arguments for both
Sand - 120 go over the plaster take the lumps bumps nodules out of it any holes fill then sand back to flat
Paint- first coat about 10% water
Sand- 180 grit barely have to touch it more rubbing your hand over the wall whilst holding it usually doesn't even take weight of your hand.
Paint - now apply your last coat. Once your roller goes of Make sure it doesn't come back off the wall, vertical movements, do a whole wall then start on the next wall once you finish that one go back to the start of your first wall (the idea being give the paint a few mins to tack off a little bit) don't load any extra paint on your roller and run the roller over the wall again vertical strokes to roll out any lines left from paint application.
Unless your wall needs another coat your done. If it needs another coat or you just want to give it one sand again with 180 and start the paint applying process again.
Use quality rollers and if possibly a roller pole that way you can go bottom of wall to top in one smooth fluid motion.
Using this technique from start to finish gives a fantastic finish even in silk!
B&Q sell Leyland white or cream in their trade catalogue for 16 excl VAT paint like this is great I've used loads of the stuff!
Hope that helps bud

Should have said after the first coat you will be able to see anywhere that is high or low so needs sanding or filling. Do this then touch them back in with a whitewash then the 10% diluted coat 180 over the top then will be fine to go with final coat.
This sounds like a lot of work but with good plaster sanding and filling is an hour. Be ready for final coat within half a day.
Awful plaster is a day's work.
Most of that time is waiting for paint and filler to dry.
Be sure to wipe the walls down between coats with a damp cloth to remove dust and keep a Hoover the hand to pick the dust up

so even though its previously been coated in paste and wallpaper it still needs pva sealing/white washing?

If it was me doing it in my own house I would sand it because of the paste then yes pva or whitewash.
But I'm a perfectionist if I know somethin is there It will always catch my eye.
If your not too bothered I inagine the past will do a sufficient job of sealing the wall, if it hadn't been done beforehand the plaster absorbs some of the paste and seals anyway. You will get away with that I reckon..

50/50 emulsion and water is what I've used on the recommendation of 4 plasterers

Yeah if it doesn't need to be perfect than just put the paint on. Doesn't need sealing will have already been done or the paste would have been absorbed instantly and the paper would have fell off haha

It's to seal the plaster so that it doesn't absorb the paint. You can paint straight over the top of it but it probably took more paint than if you had sealed it. The pva and water stops the plaster staining too (within reason) from grease or oil and the likes

Dee, if it's new plaster why would he need to fill low and high spots on walls? Just mist coat then give it a light sand with a sanding pole once dry.
Next coat water down about 10% just so you get a nice flat first coat, or an additive like Floetral which gives you a nice wet edge.
Only time I've ever had to rub down new plaster was when working on a recessed ceiling which had lights shining across it and it needed high and low spots flatening out

Same here, had a new ceiling in my kitchen and painted straight over the bare plaster. 3 coats, looks fine.

Because when you want to paint that ceiling again all the paint will fall off the ceiling onto the roller as you haven't given it a base to adhere to.

In a kitchen? Where you're cooking and washing the ceiling will always end up getting grubby. Not sure why you wouldn't mist coat anyway? 1 mist x2 solids is usually enough to cover anyway, doesn't take 5 mins to mix up some water into emulsion.

My previous ceiling was fine until it fell down
I'm not a professional painter though so it may not have been up to standard.
