Before sleeping in it? I mean maybe wait until they've left the property then your good to go, gonna be a moist few nights though. 2 weeks is standard until its dry enough to start the painting process so long as there is some good passive ventilation and its reasonably dry time of year, if its wet as hell then up to a month before you can start painting, or gently force dry it with a dehumidifier (my new best friend to speed up the process on various things!).
How long do I need to leave a freshly plastered room before someone can sleep in it? Plasterer says room plastered this week will be OK for Christmas but room done next week won't, still too damp. I'm hoping he is just being extra cautious. If not, Christmas at my parents is going to involve my husband and me sleeping on the floor in the living room :(
