Prodeck Rubber, a rubber resurfacing distributor, states "Rubber Decking does not retain heat. Unlike other porous materials like brick or concrete, UV Rays are reflected off the rubber due to the polyurethane binder that is used when mixing and applying the rubber pool decking. This polyurethane protection also ensures that there will be no ambering (yellow tint) effect on the rubber surface once exposed to countless hours of sunlight."
