I have had a bad time with a new ceiling I had installed.
About 5 years ago I had a ceiling installed and painted with Latex paint.
The next year the paint started to peel in some pretty good size pieces. Not sure what to do now but in the past I scraped, sanded and used Kilz. Then painted with latex again. In 3 months I saw peeling again in the same places. There is no signs of Mold and I do have an exhaust fan to the outdoors. Appreciate any help.
ok lets start with a couple questions
the exhaust fan. Where does the exhaust go?
Does it go up above the bathroom to the attic or does it actually exhaust out through the roof?
Question number 2.
the painted surface (the cieling)
You applied PRIMER before the latex paint yes?
Its a bathroom, Are you 100% sure the surface was 100% dry before applying the paint AND the primer?
I have to ask about the surface because you said you had it installed.What could be happening is either moisture is getting in from the TOP of the ceiling (attic) or it was already there before the primer went on (contractors did it) and the result is sheetrock that has moisture trapped in it forever.
Personally i would NOT be using latext paint in a bathroom
Kitchen, living room, befroom, pantry yes because these are areas that need paint that wont accept dirt and it easy to wipe clean
How often do you need to wash a bathoom cieling ?
Was this new ceiling you installed drywall.? If so, what step by step procedure did you perform to finish it.?
Knowing the type of ceiling and the procedure to finish it will help us help you.
Also, you say you have a ceiling fan..... What size is it.? Compared to your bathroom.? How much incoming air do you have.? In other words there's a gap between the bathroom door bottom and the sill, how much.? When you take a shower does it look like there's moister on the walls or ceiling.?
Ceiling fans/windows can only exhaust as much air that is entered. In almost all cases this air only enters from beneath the door, and it's not uncommon to have as much as 1/2" - 1 3/4" space between the sill and the bottom of the door. Sometimes a timer needs to be install to the exhaust fan ( 5 - 10 minutes) so it will continue to exhaust the moister, even after you leave the bathroom.
