This is the bathroom- What is your recommendation?

you cant paint acrylic over oil unless its been well prepped but you can paint oil over acrylic i would try a really good sandind

It looks like the paint put on was not the same that was there before. Latex will not go over oil based paint.

You need to prime the wall before painting new. Use Kilz primer. Also make sure you use a bathroom paint.

In a previous post you said you house is old. It probably has oil based paint. the test for oil based paint is to rub the paint with a little denatured alcohol on a cotton ball. If paint doesn't rub off, it is oil based paint. You will need to prime with a "bonding" primer before painting with a latex paint. Bonding primers may be latex as long as it says "bonding" on the label. If it is latex paint on the wall, you will need to eliminate the moisture problem and remove the loose paint before repainting with latex paint. The only other reason paint would peel like this is if the wall was damp when you applied the paint. Do you see water stains on the ceiling near this wall? If so, you probably have a water leak and need either a plumber or a roofer, depending on what is above this wall. In any case, you should install a vent for the bathroom to prevent mold and mildew. There are vents that go through the wall, if it is too difficult to go through the ceiling. If the house is old, the paint is most likely lead and you should not be sanding it yourself. The dust from lead paint causes brain damage when accidentally ingested. Professionals are needed to remove the paint and for proper clean up and disposal of the lead dust.

To me it looks like it may have been painted while it was raining outside. The humidity will get under the new paint and make it peel off like that. Best bet, scrape as much off as you can and start over with a primer and then paint again.

HI. It was painted in summer.

I'm thinking maybe the primer wasn't the right one. I don't have the original anymore and can't remember what it was.

This was My mother in laws house and we carried on with what was here.

Clearly labelled where it was to go.

Thanks for the feedback tho much appreciated

If there is no lead, scrape and sand. Apply a high-adhesion primer, and recoat with a paint of your choice. Check the paint can label if in doubt. it will tell you if you can recoat with latex.

Yes. It could be the primer wasn’t the right one. But make sure there isn’t any dampness. Perhaps just a slow leak that is enough to cause mold growth but no water stain. I have seen this happen. Don’t just look for leaks, feel for them and do it after a hard rain. You will have to check with your local authorities about options for workers ng with lead painted surfaces.

That is probably the answer. To add to my answer: You will have to sand the peeling paint. Sometimes washing with water will help the paint you put on peel off more. Better to get it off now before doing all that work again. Get a primer such as Zinsser B-I-N-S Advanced Interior Primer which has shellac in it. It is low odor and blocks stains. It can be used over and under any type of paint. Sorry for the delayed answer.

Looks like there is not enough ventilation. A good exhaust fan or an open window can clear the dampness from the room. The paint can be scraped, primed then painted with a bathroom approved paint but there has to be good ventilation.
