Hometalkers, what's the best way to seal in odors in concrete?
We moved into a house in which the cat was urinating in the concrete floor crawl space. We used Nature's Miracle, thought it was gone, and my husband painted it with DryLock. But now when it's humid the pee smells return. We can't access the cement now that it's been painted, so I'm thinking we seal it some more with Kilz or some other lacquer. Thoughts?
