Never had much problem with paint, but I did use Dulux bathroom (in the bathroom). It is fantastic for mould and moisture resistance, and things like toothpaste can be wiped off easily. I will probbaly use that in by bedrooms when I can be bothered to decorate, as the stuff used before (Crown I think) does not seem to hold up on the surface. I've got mould coming on nearly all of the ceilings, and whilst this may be a ventilation issue, I do not have a single mark in the bathroom
