A friend of mine bought a house with the oder of cat urine throughout... he got a really good deal... I guess. It's a refurb he plans on selling. He's tried priming the entire basement with two coats of Zinsers BIN. Now the flooring guy says he is going to put a few extra coats of polyurethane on the floor to try to mask it.
I have heard many times that it is impossible to get rid of the smell of cat urine in an old house. Do any of you know a good way to get rid of it?
