Painting new plaster

OneADay

Just had some plastering done, one ceiling and couple of walls patched/skimmed.

Plasterer mentioned using white matt paint - can someone with knowledge recommend a good paint.

Do I need to use supermatt (read someone on internet that is what should be used). No idea what to choose.

I used dulux supermatt. Follow instructions on watering it down, especially first coat. Worked really well on our freshly plastered walls.

Hi, just had our whole house skimmed throughout, all walls and ceilings. 3 coats of normal white dulux matt on the ceilings and 3 coats of coloured emulsion on walls. I know there is a lot of various thought on painting new plaster but my plasterer basically told me it would take 5 coats of thin paint or 3 coats of decent paint. Apparently once the skim plaster has properly dried it can be painted just like any other wall. Hope this helps

there may be " a lot of thought" on painting new plaster , but there is only one way to do it and that is to follow the maufacturers ( who should know their own products) instructions ... it is not rocket science ,

you need to seal new walls with a mist coat(thiined matt emulsion ) then put a second coat on with a drop of water to thin it down and then a third coat which can either be neat of have a drop of water in it .

if you put neat emulsion straight from the tin then the new plaster will suck all the moisture out of it and form a skin of paint that will not properly adhere to the walls , this may not be a problem now but when redecorated , moisture from new paint may cause the old paint to lift/bubble from the plaster and peel .
this has just happened to me on a house i am painting at the moment , the old paint it stripping off like wet wallpaper , also the same thing will apply when walls have been "sealed" with pva glue another bodgers favourite method

I picked out this Dulux Trade Supermatt to use for the first layer

Is this ok - and will thinning instructions usually be on these cans or is just rough 30% water to thin?

Why is white coat recommended? Just wondering.

So my first 3 coats will be

1. Thinned by 30% water
2. How much is a "drop of water" ?
3. Either thinned or out of tin?

And after that I can put what I like on it...

While this is here...

We're due to have one of our rooms skimmed on Tue, the guy said to strip the wall paper (lining paper) from the walls and ceiling. We have done this but there's paint underneath - will the plaster adhere ok to this paint?

Never even thought about it until someone mentioned it earlier, got Mrs sancho all worried about it

The mist coat goes on because new plaster, even when completely dry will suck all the water out of whatever you put on. Hence first coat needs lots of water so the plaster can suck up whatever it is go suck up.

There are instruction on the tub, but better to be too thin than too thick as the worst that happens is it takes an extra coat...
