I have always used diluted emulsion and have never had any problems.Painting newly plastered walls?
Hi,





The best way is this, Mix 50:50 water:water based emulsion, for every 2 litres of watered down paint, add approx 300ml of neat PVA.





Do one coat of this, allow to dry, then, get some 120 grade sandpaper, and go over the walls taking out any little discrepancies, like nicks or drips of paint.





Then apply 2 coats of paint (normally water based emulsion or Vinyl silk if it's a bathroom or kitchen) in the colour of your choice.





This should give you an ace finish.





If you just apply emulsion straight out the tin onto new plaster the porous plaster will 'suck in' or dry too quick and the paint may peel, also, if the plasterer has been a little over keen with their trowelling or it may have dried a little too fast for him, the plaster might be a bit shiny so this helps the plaster adhere to the shiny surface.





This should give you a great finish, hope this helps.
I went to college to be a Painter and decorator. Myself and other apprentice time served decorators have been doing it the following way for decades.





Wipe your hand over the walls. If there is signifcant powdery residue, wash the walls with clean water.





There is no dedicated primer for new plaster. There are specialist primers and sealers for problem areas, but a skimmed wall that is sound is not a problem. There is a movement to use specialist primers on new plaster but it is completely misunderstood by DIYers.





The first coat of paint you thin with water to a little thicker than milk. The reason is to encourage the paint to soak into the plaster and get a grip. If you put neat paint it tends to lay on top of the plaster which is not uch a good grip and may peel off easily in the future. On the first coat it is better to brush it on rather than roller it, because you want to get under any bits of powedery residue on the walls - so you work the brush in various directions. If you roller the first coat and there is residue, it will act as a barrier and stop the paint soaking in.





After applying the first coat thinned and with a brush, you can roller two further unthinned coats.





Never ever put PVA, wallpaper size or any other glue as a base for emulsion.
And after all of those fantastic bits of advice above, just use Leyland's Super Leytex emulsion, straight from the tub. If you want white or maggie, two coats will do.





If you put soft sheen on, one coat of Super Leytex first then two soft sheen.





College will tell you to water emulsion down first, but from experience (and saving thousands of hours) Super Leytex is the answer.
By the terms you use in your question you have to be from the UK. That's great,but in the States, the advice I'd give you is this.I sold paint for a living for many years. To begin with that skim coat needs to cure for at least 1 month.This is important. Then apply one coat of a good primer, then two coats of a water based paint(emulsion) in any finish you like.Hope this helped.
Most paint companies do a special base paint for newly plastered walls which you can mix to any colour you like. Try asking at a specialist decorating shop rather than a DIY warehouse.
you can buy a base coat which is designed for going onto plaster before you paint you can buy it from B%26amp;Q, not too expensive either!
We always used a diluted coat of emulsion first to seal the plasterwork. Then a couple of coats of emulsion covers it.
I've just painted my newly plastered walls, two coats of cheap matt emulsion is the answer, I used white because I was have light coloured paint.
Sugar soap will only clean paintwork. The best is to seal the new plaster with PVA. Dilute emulsion is not a great sealer and messy.
3 coats of emulsion will do the trick.
use sugar soap
