gym mats

Rubber floors or mats are commonly used in gyms or for athletic activities. They are placed under exercise equipment to prevent the equipment from damaging the floor beneath it, or are used to provide a softer flooring surface, commonly used by wrestlers and gymnasts. Routinely clean the floor to remove dirt, dust, reside and buildup. If buildup remains on the rubber flooring, it can cause the flooring to become sticky or slippery.
