AFM SafeCoat WaterShield is intended for porous concrete type surfaces only. Since the walls have been painted, they would no longer be porous and the WaterShield would not penetrate through the paint. We offer a very good waterproofing topical membrane called Dynoseal that can be used on foundation walls. However, if the paint is failing in any way, the adhesion of any new product will peel along with it.There is no magic bullet that can be applied over the surface without first removing the existing paint. While that may be messy and expensive, it's much less expensive than doing foundation work.
