    Why did you use PVA ? PVA should never be used if the surface is to be painted over. Dont believe what they tell you on the tv programs!!! On an MDF bath panel, all it needs is an oil based primer then undercoat then topcoat, rubbed down between coats, and make sure the end grain is well painted or it will soak up water like a sponge !!

    DO NOT USE PVA BEFORE PAINTING !!!!!!!

    If all the wood was painted with PVA then the top coat might just peel off.
    Its not so much the topcoat, but the PVA, it causes all sorts of problems after. You could try flatting it off and giving it a coat of undercoat and see then how stable the surface is.

    Bit of a bummer but pva on mdf is a no-no.

    Infact PVA is a mare on most things bar pre-plastering.

    I am guessing that the hot water reactivated the pva.

    I would suggest sanding it back- quite a chore. sorry.

    I use water based primer on mdf ordinarily but not in bathrooms.

    The mdf should also have been the moisture resistant type.

    Subsequent coats of oil based primer/undercoat will help but as robbie said- pay extra attenion to endgrain.
