My wife's stupid cat has used a corner of out living room to piss in off and on for year - usually when the weather is bad outside she'l use the corner instead of venturing out the cat door.
So, we decided to pull up the stinky carpet and put down hardwood floors. Today we pulled up the carpet and discovered the OSB board underneath also reeks of canine urine.
So we used a strong detergent and let it dry. Still there's the odor although only half as strong.
I could replace the OSB but that's a lot of work. What if I paint over it before putting the hardwood floor down? Do you thin any odor would waft up into the room?
Thanks for your feedback.
