We have an on-going problem with an internal bathroom (no window) and paint peeling off the ceiling.
I sanded it and painted myself - about 2 months later the paint was peeling off again.
We got a professional painter in who charged €100 just to paint the ceiling in a small bathroom. He used Polybond and now a few months later, it's peeling off again.
I asked in the local hardware store (Heitons) what I could do and they recommended Zinsser Perma White. They don't stock it, so I've tried Woodies, Atlantic and B & Q - they don't have it either.
Does anyone know where this product is available?
If I can't get it, I will try the Sealapore Alkali Resisting Primer Carpenter suggests - if I can find it.
The only other thing I can think of is to put polystyrene tiles on the ceiling. I know people used to use these in the 70's/80's - are they still available and would they do the job?
There are already 2 extractor fans in the bathroom - one directly over the bath/shower area.
