Painting fresh plaster ceiling

Soubrette

Hi guys

I've just had my ceiling replastered over artex (no one could apparently repair the small amount of damage to the artex and this was the only option) Unlike fresh plaster on a wall, this is only a thin layer and so has dried out really quickly.

So now it's time to paint it and I've had a couple of recommendations.

1) half water, half emulsion first coat, let it dry and then two coats of ordinary emulsion.

2) 1/4 pva glue, 3/4 water first coat, let it dry then two coats of ordinary emulsion.

Does anyone have any idea which is best?

Also for the first idea, I've been told that it has a consistency of milk - is there any neat way of rollering it on so it doesn't end up rolling down my arms?

Thanks

Sou

thinned emulsion is the correct way to seal new plaster
do not listen to anyone who tells you to use pva
a milk consistancy is about right , you just have to be careful when rollering - take it easy and you won't get too many spots

Yes, this is the correct way to paint new plaster.

No, your mix should be 4:1, paint:water.

This is what is known as a mist coat, and should be around 80% paint, 20% water. It will be thinner than usual, but not so thin its going everywhere:eek: .

If I could come into this thread, our ceiling in the bathroom is peeling (new build 2005), I want to put right but wonder exactly the best way to go. Where it has peeled the plaster is clearly seen (wonder whether the builder bothered with a mist coat or just slapped it on..) clearly need to remove the loose stuff and rub down? But do I just take it back until the loose stuff is clear or do I need to strip back all the paint (a bigger job). Do I need to seal this and then use a bathroom emulsion? Any advise / pointers greatfully received. Thanks !

Hi,

I'm in the process of having my whole house plastered and my plasterer reccomended just using a cheap white emulsion as it is thinner anyway. Then you dont have to mess about adding water to it!

Painted one room so far and its looking good!

We had our bathroom ceiling replastered and this is the mix I used. Two coats of that and then a coat of full emulsion.

Hiya

The need for watered down paint is that it 'soaks' into the new plaster, thus giving a better bond, takes longer to dry, etc. So in theory it shouldn't peel;) .

Using a cheap emulsion doesn't necessarily give the same effect. Cheap doesn't really/always mean its got more water in it. Usually it means more 'fillers', less 'opacifiers' etc. You should still water down the cheap stuff.

So buy cheap stuff & water it down, is what will work equally well.:rotfl:

Hi there, do you know if there is a matt finish on your ceiling, or a bathroom paint, or even a silk finish?

I would put money on it that the builder didnt mistcoat, and I bet you have bleeding knots through your woodwork as well :mad:

I dont think you have to strip back all the paint, just sand down where its flaking, and if you have rubbed it and its gone back to the bare plaster, thats not a problem.

If certain bits/patches have gone back to the bare plaster, then knock up some filler and just lightly skim over these patches.
Leave to dry, then gently sand, rub your hand over it, and if it feels flush then its filled enough, if it still feels indented, then lightly fill again.

Once its been filled sanded and your okay with it, then before you actually paint your ceiling, pour a little Matt paint into a container, add a bit of water, and stir.
Then brush the diluted paint over where you have filled, do this about 2-3 times, letting it dry in-between.
Then roll as normal.

If you want to use a bathroom paint, personally I would put a coat of matt on first, then do your top coat in your bathroom paint, but again, just slightly thin your first coat of matt.

Hi misgrace and thanks for that, do you think if the plaster did not orginally have a miscoat (i'm guessing not) then it will peel again after the re-dec or the work we do with applying the miscoat and then top coat will be an effective seal. Thanks again

Normally I would thank all contributors and advice but I wanted to post to say that I used 80% dulux/20% water - two coats of this and one coat of dulux and my ceiling looks fantastic :j :j

Thanks guys
