Liquid Painting Silicon PU Coating Rubber Sports Court Flooring
Liquid Painting Silicon PU Coating Rubber Sports Court Flooring
Production Description
The purpose of building sports courts is to ensure a professional, safe, healthy sports condition-the characteristics of hardness will bring the professional sporting feeling; the cushion effectively increasing the shock absorption and reduce the incidence of injuries to ankles, joints and ligaments. At the same time, it should reduce abrasion caused by falling and accident.
It’s suitable to lay on concrete or asphalt substrates. The cushion elastic bottom layer plus with high performance top layer is both in good function and also cost saving.
