Damp paint

Osarahlou

So I’ve recently had a bedroom skimmed, I did a mist coat which dried fine so I added a coat of paint on Monday but there are some patches on the celling where is hasn’t yet dried, these patches are where we had mould on the celling before it was skimmed any ideas what could be causing it and how I can fix it?

it could be how you have treated it did you remove the mould before skimming over it
How did you clean it with what and did you put a stain blocker on it
mist coat is good id wait before putting any more paint on
whats above the ceiling is it the loft or another room
if its a loft then is it lagged
good luck
