There are two approaches sprinkle and spraying granules
Sprinkle granules mean that first scratch 2mm comprehensive material on the elastic layer, then sprinkle EPDM/PU granules on the layer averagely by worker. After curing, sweeping the surplus no adhesion EPDM granules on the surface and finally spray glue to strengthen on the top layer.Spray means using spray equipment to spray mixed EPDM granules and fabric to the elastic layer.
