I'm in the process of having a conservatory built and it's at the
state where all the glazing is in, first fix of electrics and the
plaster boards put up and skimmed. The plasterer guy reckoned it could
be painted 'by the weekend', which was the weekend just gone, and he
said that on the Tuesday when he did the work.

Now here we are 3 days beyond that and the skim has dried to a light
brown even finish all over, apart from where I suspect the adhesive is
where the boards are glued to the blockwork. These spots are still
darker, I guess about 6 inches in diameter each and occur in dots of
four, like the spots on the four dice face. The even colour arrived
within a few days but these darker spots have been there since about
saturday. They seem to grow and shrink in size with the time of day as
well, if that makes any sense.

Is this okay to paint at this stage? I'm going to put some Dulux
'paint for new plaster' on first, then some hard wearing emulsion on
top.

How long do I leave between the two coats of paint, assuming I can
even do that yet. I'd like to get it all painted before the second fix
of electrics if I can.

Cheers

Gary

To be honest, I would waint until all dark/damp patches have dried
fully - you risk the paint not adhering properly and flaking off.

I used watered down emulsion for the first 2 coats of mine - and it
was dry to the touch minutes after it hit the wall - so I would say
you could get away with ~2 hours between coats - new plaster is very
thirsty!

That's expected. Moisture is slowly coming though from the glue,
but when it's warmer/drier, it may dry from the surface faster.

I'd echo that - leave it a few days _after_ it all looks dry.
Start with watered down matt emulsion, even if the final paint
finish will be something different. If switching to a different
paint between coats, wait much longer than just dry to touch.

I'd echo that as well.
I used 2 or 3 coats of watered down cheap emulsion as first coat, then hit
it with some decent stuff. Perfect finish.

It's not obvious to me why you want more than 1 thinned coat,
but I doubt it's going to do any harm.

For the first thinned coat, it wants to be more thinned the
more polished the plaster finish is.

Each subsequent 'mist' coat watered down less each time. Final coat was
good quality full strength emulsion.
