Cement floors are probably one of the most popular types of kennel floors. They are certainly easy to lay, they provide a smooth even surface for your pup and they are relatively easy to clean as you can simply hose them off as needed. Unfortunately, cement is actually extremely absorbent meaning that it will not only absorb urine but the odor will remain. If you are planning on using cement flooring in your dog kennel it is imperative that you seal it well beforehand.
There are quite a few good sealants on the market, however regular epoxy garage floor sealants for example, may not be idea for kennel use. A garage floor sealant is specifically designed to use on a garage floor. For the best sealant, look for something that has been designed specifically with kennels in mind.
You will find that there will often be a deep sealant that protects the concrete from absorbing water from underneath, in the ground, and a top sealant that seals the top of the concrete so water or other liquid does not go down into the concrete. A good surface should also be non-skid, it should provide your dogs with sufficient traction and stability so that they are not slipping around the kennel flooring.
Your sealant should also be non-toxic and there should not be any unusual smell or odor after using the sealant. You may have to let it dry for a few days before allowing your dogs on the cement, but once it is dry it should be odor free.
Finally, you will also want to provide your dogs with dog beds rather than letting them lay down directly on the concrete flooring, even if it is well sealed. Concrete is cold and it is also very hard on your dogs paws and joints when they are resting. For optimum comfort provide them with an actual bed that raises them up off the concrete. There are many of these types of beds available and most are relatively inexpensive.
There are quite a few sealants online that cater specifically for dog kennel floors. It is best to choose these over regular sealants or epoxy sealers as they will be better for your kennel hygiene and cleanliness and better for your dog as well.
