I need to parge my foundation walls, using latex to saturate into the sand/lime mortar mix that the foundation was built with. The problem is that somebody in the past painted over the problem with some kind of resilient paint. I have brushed and rolled on 4 different kinds of paint remover to no avail. I want to excersize every chemical option before I break out the grinder with the wire wheel brush.
Any of you know of some kind of super paint remover?
