I am wondering how to remedy the peeling paint on my bathroom walls. About 6 months ago I repainted the bathroom, after sanding off the layer that was already peeling. Apparently I didn't sand deep enough, because now the new layer of paint is cracking and being pushed up. It appears that the peeling is occuring from deep beneath several layers of paint, since the layer that is pushing up is very thick. How do I go about stripping all those layers of paint? Thanks for your help!
