    Are you sure that's not a water leak?

    Peeling paint. was it from a leak? what condition is the drywall?

    Something had to cause the paint to do that. Do you know what it was so this doesn't happen again or cause damage?

    You need to identify the source of the water damage and then replace the section of damaged drywall.

    Folks it isn't necessarily a water leak problem. My daughter and husband have the same problem but much worse in there upstairs bath. They have found it is caused just by moisture from showers with no ventalation. Will be following this post to see a "fix". We have tried installing an exhaust fan but nearly impossible with the roof line so a window is cracked at all times.

    Hi! That definitely looks like your damage is due to a water issue . Did you resolve that problem , if not , don't try to fix the ceiling yet !!! If you have fixed it , you will need a scrapped to scrape off all bubbled paint and flaky sheetrock. Then you need some spackle. , spread it thinly over the area making it smooth , spread it even thinner at the edges . When dry , sand it smooth especially where it meets the untouched ceiling . Then it should look normal , no bumps , or edges showing , then paint it . Good luck !!!

    Yep, I agree with Rae. This looks like it was caused by steam. Generally if it’s a water leak there will be a yellow ring and bowed drywall. First you need to scrape away the loose paint. Make sure you wear goggles and have a tarp down. That stuff will be everywhere. Sometimes you find out you’ve opened Pandora’s box with scraping because the pressure you place on the ceiling may release a whole bunch more material than you bargained for. Chances are good if steam caused those spots to be loose, there are others on the brink of collapse as well. I can’t tell by the pic how textured the ceiling is. Is that just flat paint? Is it popcorn? (Doesn’t look like popcorn). After you get the stuff that is unstable off you need to decide what’s next. If you own the place perhaps you can make this your last bathroom ceiling repair. Consider architectural tiles for the ceiling. The ceiling surface must be stable and if you scraped off the loose stuff it should be. You can cut them with a knife or scissors and use permanent construction adhesive to glue them in place.

    If you decide to repair and paint instead, use drywall compound and a (4-6”) taping knife to smooth the material onto the scraped areas. Try to work in thin coats to eliminate sanding as much as possible. Some drywall repair compound changes color when dry. That may be easier for you to use. The other stuff is cheaper. You may be surprised at how much you need, so when in doubt buy the larger size. Also, if you go where the drywall is, there will probably be large contractors tubs of compound that you think you will never need for the rest of your life but is still cheaper than the little bitty containers that are in the paint aisle.

    You apply the drywall compound and leave it alone for an hour then touch lightly to make sure it’s dry then sand and reapply. If you are in a hurry and haven’t sanded you can use a blow dryer to dry it faster. When dry, you can use a sanding sponge to sand the repair— make sure to wear goggles and a dust mask!!! Also close the vent and door or your whole house will be full of dust. Once you have sanded you may need to reapply in some areas and sand again. Unfortunately the best paint to prevent future problems is the glossy kind. That is unfortunate because the more gloss the worse your repair will look. If the only area that comes loose is restricted to the shower area you could paint that area gloss and keep the rest of the bathroom ceiling flat. Sounds strange but I’ve seen it done and with a shower curtain in place it wasn’t noticeable and no doubt beat repairing every 6 months. Good luck!

    I agree with Rae that this looks to be a poor ventilation issue. Once you scrape off all the peeling paint you will know for sure. If it's just peeling paint the solution is pretty straight forward.

    scrape off all peeling forewarned; once you start scraping, you may notice the area is much larger than what appears on the surface. Make sure you get every bit of the peeling paint.

    Let the area dry out completely. If you need to run a fan in that room, that can help speed up the drying process.

    Once the area is completely dry, you will want to sand down any edges so you have a smooth area to start priming and painting. If you notice any staining, you may want to use Kilz paint with a water barrier first. If there is no staining, proceed with your primer layer.

    You will want a water barrier primer. Once that layer is done (just follow the instructions on the can), then you can paint over it with your desired color.

    I've done refurbishes with this issue and found that once I started scraping so much of the paint was coming off, that I just scraped the entire room (yes it's a beast of a job). Then I did a water barrier primer and painted.

    Now's the time if you ever thought of changing the color.

    Hope this helps.

      Yes they are same. As I see Texture in your 2nd photo, You may want to invest in Texture Additive for your Top Coat of Paint.
