    The best way, we've found to get pet orders out of wood or cement subflooring is to use a paint sealer called "Kilz". It usually takes 2 coats to seal a cement floor. A wood floor may require you to remove and replace some of the sub floor, especially if it has warped due to the urine, once the damaged wood has been replaced then coat the entire floor with the Kilz. The worst case of pet damaged subfloor we have experienced took 3 coats of the oil based Kilz to finally seal it. Besure to apply a thick coating and seal along the wall/floor edges.
  • Pet urine will penetrate uerethane finishes and will certainly discolor. If it's hardwoods and its stained, refinishing of the area will work if not too deep. Beyond that it's a "tooth-in" repair situation. House 2 Home covered the rest of the scenarios.

    Bleach & vinegar is the cheapest way to kill the odor. It may take a couple of applications but it is pennies to the dollar. The next best way is use Kilz. If you plan on re-carpeting your floor afterwards and still have the pets, be sure to buy the pad with the anti-microbial in it. It keeps the bacteria of the urine from growing which causes the smell. Hope this helps.
