Treating Pet Odors in Concrete
One of the most difficult odor challenges is trying to get pet urine odor out of concrete. This is a common complaint because people put there pets in the garage, basement, or porch area while they are away. Most treatments will only be marginally effective because the urine actually gets into the concrete and bonds to the material.
So, washing and scrubbing is a good idea, but not enough. Mix up enough of the CHLR99 30 gram powder in bucket of three gallons of water to saturate the area. Then, soak the floor for a period of thirty minutes. You can wet vac up the remaining water. Wear a suitable carbon mask while applying the product. Avoid splashing the product in face, eyes, or mouth.
Ventilate the area for 15-30 minutes when the job is done. Once the floor is dry, give it a day to see if the job was enough. If there is still a problem, repeat the treatment.
In the end, if the problem persists; you need to etch the concrete with muraitc acid and then seal the floor. At this point, the concrete is ready for the ultimate phase. Your local hardware store will give you guidance on the etching and sealing of a concrete floor process. It isn't difficult, but this will create an impermiable barrier between you and the odor. The fact that you have already reduced the threat with CHLR99 only helps the final job turn out better.
Floor wood floors (underlayment), follow the same process allowing enough time for the wood to dry. Sealing the wood should be a kind of paint that has an odor-blocking ability.
