Paint coming off bathroom ceiling

Hello, the paint on my bathroom ceiling is peeling off. So i intend to strip it back to bare plaster and re-paint. Whats the best way to prep the ceiling for painting (probably be matt if thats suitable?). Thanks. Phil

If its coming off in sheets you've probably got the right idea but could be hard work if you've just got patchy flakey areas. If the latter is the case, scrape off the loose paint and give the whole ceiling a coat of zinsser peel stop and then apply two coats of acyllic eggshell not matt.

If you do strip the whole ceiling and its back to plaster you will have to apply a mist coat prior to eggshell. Also worth investigating and solving the reason why it flaked if you havn't already

Use White vinyl emulsion on the ceiling, won't absorb the moisture as much and flake off.

Thanks for your replies. Its not coming off in sheets its just little flaky patches. It could be me not doing good enough prep when i painted before. I think i just slapped on some emulsion straight to bare plaster! Could i use that special bathroom paint? If so can that be used a mist coat? Phil
