Peeling paint problem

[banana]

About 8 years ago our bathroom was remodelled and thus replastered. Emulsion paint was applied (can't recall any details as to how/when etc) and all looked fine. There have been several coats applied since then without anything untoward happening. But now the paint is peeling -in sheets! When Ive pulled the loose stuff off it comes cleanly away and the plaster beneath is completely bare and smooth. There is no external dampness -and the bathroom isnt particularly steamy either. Will I have to remove all of the remaining paint?Or just the loose stuff? Anything I can do to stop it happening again?

im a painter and it sounds like it is a problem with the first coat,it was probably put on before the plaster was fully dried out and the subsequent coats are just a build on the first coat.the only thing to do is to get back to the plaster and start again .any good d.i.y store stocks emulsion specially made for kitchen and bathrooms ,it resists steam and fungus

Thanks WD .Its sort of what I expected given the smoothness of the plaster underneath. Oh Well - at least its not a major undertaking.

We "sealed2 the surface of the plaster & plasterboard with a thinned down [with white spirit] oil based paint first - either undercoat or gloss did the trick

Try puting a coat of watered down pva on before you put a first coat of paint on freshly plastered walls.

We have exactly the same problem. We painted over the old paint and it just wrapped arround the roller in sheets like you stated. We are now in the process of *trying* to remove all the old paint but cant get it all off. Tryed a heat-gun and that popped holes in the plaster, tryed steaming out the room, but that didn't help... Does it all need to be removed, and if so-- how ?! Should you use 'paint for new plaster' over the plaster in a bathroom before the new paint is applied?
