Bathroom ceiling bubbled


About three years ago, after I bought my newly paint house, the paint on the bathroom ceiling bubbled. There is no water leak from above, but I do take really hot showers and it's a small bathroom. These bubbles are just the paint that isn't sticking to the plaster. It hasn't cracked, it's just flexible paint hanging down a little bit, I can push it up but it falls right back down. Oddly enough, it's stayed like that for 3 years, it never cracked or anything.

Since I will be re-doing my tub I figure I'll also repaint the ceiling. I assume I have to rip these bubbles off and keep scraping until all the loose paint is off, then sand the transition smooth, is that correct?

Second, what type of paint should I use to avoid this happening again?

The paint that they used to paint the ceiling and walls is just typical Sherwin Williams semi-gloss white paint that you'd use on molding.

I had a similar problem once with my small bathroom. I scraped off the bad areas and patched them, and then repainted the whole ceiling with bathroom paint. No problems since, and it's been 13 years.

Regular latex will allow moisture through, and that ruins the bond beween the paint and ceiling. Bathroom paint blocks the moisture.

DO you have good venting in this room?

Yes, I installed a Panasonic exhaust fan a few months after I moved it. At that time there were already some bubbles, however, more have developed since installing the fan.

You might want to try using a de-humidifier in the room. Then when you see little to no water build up in the tray, then paint. There may be a lot of water built up in your walls as a result of no venting. Just a thought.

I installed the exhaust fan (oversized for that size bathroom) 2 1/2 years ago. There could still be water build up from back then?

You also might want to use a spackle, then sand smooth. Prime in a oil primer, then top coat in latex.

But I would be really concerned about why the paint bubbled in the first place. How long do you use the fan when using the bath/shower? 15 to 30 minutes is pretty much the norm after use.

I have a timer, the fan runs for 10-15 minutes after the shower.

I figured the paint "fell off" the ceiling simply because it is not the right paint for a bathroom.
