The installation of wet pour rubber surfacing is a two-part process. The first layer includes large granules installed to provide cushioning, and the second one involves colourful and smaller granules. The two layers are bound together using a polyurethane resin binder to provide a seamless rubber surface. Different types of rubber granules can be used to create a wet-pour rubber surface. The primary types of rubber used in Australia include EPDM, colour-coated SBR, and Rosehill TPV rubber granules.
