I've recently had my living room and bathroom ceilings plastered. How long should I leave them to dry before painting them? Also, do I need to seal them with anything before using white ceiling paint? Thank you!
You should be able to see when the plaster is dry, but indoors in a heated room 3 days should be plenty of time. Paint the first coat with a mist coat, 60% paint mixed with 40% water, allow this to dry overnight and then two coatsof normal paint should be fine.
2 coats.......my butt. Have got to paint all my ceilings downstairs, all newly plastered. Mist coat, then 2 coats........and they STILL need another coat. As for the coving, they are going to need another 2 coats. Jeez......I really don't know how you painters can do this, day in...day out. I'm bored shitless.
