Re: Getting out cat pee smell???
Cat urine is one of the worst to try to cover, and that is all you can do is try to cover it up.
You are on the right track with replacing the carpet and pad, as well as sealing the floor with BIN primer. Question, how many coats of BIN did you use? One coat is not enough, it takes two coats minimum, more if you know the urine made it all the way to the surface in which you are sealing.
While you were sealing the floor with BIN, did you also do the walls and ceiling? Because drywall is porous, it will harbor odors. Seal it up with BIN followed by a couple top coats of your favorite paint and you should be well on your way to solving the odor problem.
I once had to remodel a home that had been inhabited by dozens of cats that had no litter box, so they used any surface they happened to be on. The stench in this house was so great that you literally could not breathe. We started by stripping all the floor coverings out of the entire house, we then treated the slab floor with a urine neutralizer, then pressurewashed it. That was followed by sealing every single surface in the house with many coats of BIN, culminating in completely repainting the interior. We then spread baking soda on the floor and laid new carpet and vinyl. By the time we were done, there was just a hint of a musky aroma. There were budgetary constraints and this was a government job, so we couldn't do what I would have preferred, and that was to strip the place down to bare stud to completely get rid of the odor ridden drywall.
