i've been plastering for about 3 years and i have always believed that you should leave new plaster for 5-7 days before you paint it or until it is completely dry and then you should use a 50/50 coat of water and emulsion prior to painting.
a mate of mine has just had some plastering done by someone else as i couldnt do it quick enough. the plasterer said he could paint it that day, as in as soon as the plasterer had left and he didnt need to do any 50/50 coat or anything.
a bit confused..........

If itís a skim coat then your right & he's definitely wrong & I actually advise 10-14 days; base coat & skim should be left for up to 4 weeks.

Thinning 50/50 is too thin 25% is enough & if your mate hasnít done this for the first couple of coats, his paint will not have stuck to the new plaster at all well, will peel off in great chunks with any wall paper put on there in the future & may even crack & fall off on itís own as it all dries out.

Just wait until it's pale pink - it's not going to get any drier no matter how long you leave it.

You obviously don't work in the real world do you? icon_rolleyes.gif You might also notice the mist coat makes it a bit moisture laden. Come on get a grip - EVERYONE paints it when it goes pink and dry.

either way, painting as soon as the plasterer leaves is surely asking for trouble??

Yes. Let it go nice and uniformly pink - then paint it.
