For on-site applications, rubber granules are mixed with binder and applied to the surface. The surface is leveled with a finisher and allowed to cure. For this application, the surface must be leveled and free of oil, dirt, dust, and chemicals. The binder ratio should be at least 18% for SBR or 20% of the kg of EPDM granules used in the application. (For a 1 mm thickness, use 0.8 kg EPDM and 1 kg SBR.) This method of production is suitable for rubber granules with a diameter of 3-4 mm. As the size of the rubber granules decreases, the amount of binder required will increase.
