Hastily signed a lease, later discovered a cat pee smell throughout the hardwood floored living room and bedroom, with some spots smelling very strong.
We have tried to deep clean with pet odor mops, enzyme cleaner soaks, diluted vinegar, and hydrogen peroxide to little effect. I'm sure the smell is in the subfloor as well.
Tore out & replaced the visibly stained quarter round trim and painted over that and the moulding with an odor blocking primer plus regular eggshell paint. That did seem to reduce the smell.
Would it help to use the same process on the entire floor? Possibly an odor blocking primer followed by a porch enamel paint, and maybe polyurethane? Tearing out or refinishing
