QUOTE (MatzoB @ Mar 26 2009, 08:27 PM) I read previous threads on this topic but I still have questions. The baseboards of a 1100 sf. house smells like cat urine. I believe the previous resident had this problem for years so its hard to tell if the walls have even absorbed the odor. Would using an ozone generator be enough to solve this problem or would I need some Killz as well? I am unsure of how deep into the baseboards ozone generators will penetrate.
I don`t have an answer to your exact question, but wanted to mention that when I was dealing with this issue, I think it made a big difference that I replaced the quarter-round at the bottom of the baseboards. Evidently the urine would flow down and get absorbed by the unpainted side/bottom surfaces of the quarter-round. I could see the `water` damage on specific sections of quarter-round, and those sections reeked. Repainting the quarter-round without removing it wouldn`t have changed the state of the unpainted sides that had soaked in the urine, and replacing it seemed to me to be a fairly low-cost option. Plus it felt great to get that stinky wood out of there and know it was gone forever. (I also replaced the laminate flooring.)
