HT Products\' Kennel Seal Indoor / Outdoor Sealer Did you know that the concrete floor of your kennel is a perfect breeding ground for bacteria, mold and mildew? Concrete is an extremely porous surface that acts similarly to a sponge. Concrete will soak up liquid and store it deep down into the pores. Kennel Seal eliminates the bacteria breeding ground in your kennel floor by preventing moisture from getting into those pores. Kennel Seal will make your kennel safer, easier to clean and reduce unpleasant odors your kennel may have.
