I have a 12x14 carpeted room with really smelly cat pee and possibly dog pee smell from the last 1-4 years. I removed the entire carpet and pad and removed the carpet tack strips so all I have is plywood subfloor. I have Nature's Miracle "Urine Destroyer Just for Cats" and I searched the room with a black light to find the worst areas which are corners, along the walls and one 6'x8' area. I saturated those spots and wetted down the entire floor twice. The problem was the product was drying too fast I thought. So here is what I did, I put towels down in the corners and the worst areas, then saturated the towels and covered them with plastic and then put another towel to hold down the plastic so it could stay wet longer. On the bottle it says (with carpet) it may take 2 weeks to dry. My one question is how long do I need to keep the plywood wet? the exposed plywood dries in a few hours is this ok? Do I need to keep rewetting it? Can I rewet it with plain water? I have already used 2 gallons in this room. How long should I leave the wet towel/plastic down? When can I paint with Zinsser BIN primer?
