Hard to see in this photo but our recently painted bathroom ceiling has areas of paint that has been damaged by humidity and condensation forming after showering. Initially we used standard ceiling paint and didn't wait more than a day or two before using the shower (rookie error). I've since painted the ceiling with 3 coats of acrylic paint and will let this dry for a week but I can still see the outline of some of the damaged areas. Any suggestions on how to fix this and stop reoccurence? I've bought another fan too which I'll install directly over the shower area
