How even should the tone of new plaster be before painting?

[username132]

The plaster in the following image was applied three weeks ago and I am waiting to be able to paint over it. Does the plaster need to be a completely even tone? It has been mostly light pink for well over a week and the darker areas do not seem to be changing. We've had the heating on for a few hours per day, along with an oscillating fan and a dehumidifier.

Was it a skim over existing - or new work on plasterboarded ceiling /new plaster system on bare walls

After three weeks i would have thought it would be fine to mist coat up

What if the dark patches are PVA where it was skimmed over

After 3 weeks, i would say your plaster has dried out. It always dries to differing lighter/ darker shades of pink across the wall/ceiling. You will never get a completely even tone of colour.

What if it was? And do you mean PVA over the plaster or plaster over the PVA?

I'm not sure whether it was completely replastered or just skimmed. It happened while I was away and my mum arranged it. I've asked her to call the people who did it.

I want to remove the paint from the skirting board as well. Since I'm planning on a) removing the paint from the skirting board, b) painting all the walls and c) sanding and varnishing the floorboards, what order is this best done in? Surely, if I'm going to be applying a lot heat to the skirting board, that's best done first to avoid damaging the other surfaces?
