Do these mats have a strong chemical smell?

Our 3/4" Diamond Top Horse Mat Kits do have a rubber smell to them. They were designed for outdoor use, so their smell is a little more than our standard residential rubber flooring. To help dissipate this rubber smell, we recommend mopping our rubber flooring with a mild soap and water solution with a synthetic mop head. You will then want to let the flooring air dry in a well-ventilated space. You may have to repeat this a few times to really dissipate the smell.
