My ceiling was bubbling and peeling or a deciding to redo it. I scaped down the bad spots and put a coat of good primer on the ceiling. Waited a day then put a coat of paint for kitchens and bathrooms. Waited a day and then put another coat. Waited another day before anyone to use the bathroom. But when we have a shower little bubbles form and then disappear when it dries out. So I figure I give it a couple of days to really dry out. The issue is the bathroom doesn't have a fan. I always shower with the door and window open. Is there anything I can do, or did I do something wrong with my painting?
