My wife babysits little boys and they tend to spray everywhere. No matter what I do I can't clean the smell away. I'm guessing the pee has gone through the cracks in the peel and stick tiles and is in the subfloor. I'm planning on ripping out the top layer of particle board, replacing with plywood, and tiling. I'm wondering what would help keep the smell from coming back. If the particle board is bad, I think I will paint the bottom layer of plywood with kilz and I was thinking of doing that with the walls too since I don't really know where the smell is coming from.
One poster mentioned a skirted tiolet helped get rid of her smells thinking the urine was flowing down the tiolet bolts. Do you think there is any merit to this idea? Will a skirted tiolet help with the smell? Any other ideas?
