I recently removed some old wallpaper from my bathroom walls. Much to my dismay, there was an extreme amount of mildew left on the surface. I tried stripping the layers of paint with a paint remover (made for lead-based paint removal). I ended up with 1.5 layers left in some places and bare plaster wall in others. To sum it up, I have a very uneven surface with cracks in the plaster, to boot! Short of another stripping, what can I do to prepare this surface for painting...I've been told, also, that repairing the plaster cracks will result in a different porosity and the applied paint will absorb differently (resulting in an uneven color application). Right now, I think I'm going to have to hand this to a professional, but I'm looking for some knowledge -- how can I know when the professional knows what he's doing. What should he be suggesting as far as a solution to this mess??
