Peeling ceiling paint

[LaLaLaLavaChChChChicken]

Suggestions needed for how to deal with our bathroom ceiling. White emulsion paint has peeled in large areas and is still flaking. It was mouldy, but we have cleared that.
Has anyone successfully used the PVA glue method to seal paint edges and then painted over? Or if there a better way?

I suppose the best way is to strip it all off. That would be a lot of hard work especially if you don’t have a lot of upper body strength. I did the PVA trick you mentioned. It worked but does look patchy. It would look a lot better if I had sanded the edges of the patches to blend in with the paint that hadn’t flaked

Thanks @Lurkingandlearning We may have to. It will be a lot of work but probably worth it long term. Wonder if a wallpaper steamer might help lift off the paint?
When the bathroom was new, the fitters put a coat straight onto the ceiling and didn’t do a mist coat so it is bare plaster under the patches.

I think the wallpaper steamer is definitely worth a try. It may well drip onto your face and down your arm so be careful. You probably knew that 🫣

This happened to mine , started with like bubbles in the paint work your best off scrapping it all off and starting again maybe use a matt based paint as holds better x

There is this very product that basically glues the paint back - but you have to remove the lose bits and sand the area before applying.

DON'T USE GLUE.

First thing is to get an effective extractor fan, and use it. Preferably wired so it comes on with the light switch and has a 30 minute overun. Once you have corrected the damp and humidity, emulsion paint will do, with one or two mist coats on bare plaster. Insulate the ceiling from above so it is not cold enough to attract condensation.

The best ones, from Envirovent or Soler & Palau, have ball-bearing motors on rubber mounts, and are very quiet. Running costs are negligible.

Thank you so much!
