A housing inspector suggested I post this topic. I need help understanding what, if anything, can be done to remedy the following problem. For no reason I can understand, a waterproofing company used Black Jack Roof and Foundation Coating on my INTERIOR walls, covered with plastic, and said this was better than what I wanted to do. I wanted them to put Aquafin on the walls, primarily to make the old, dinging, unfinished part of my basement look brighter and a little cleaner. Now I'm trying to figure out what to do. The house stinks like tar, the basement is black and ugly. Any ideas?
