The underlying surface is first cleaned of all dirt and loose debris before being prepped for installation. Once ready, the surface is primed with a mixture of polyurethane resin and a small amount of a thinning agent to allow the resin to cover the surface more easily and prevent bubbling from excess resin. All edges are primed with straight resin for extra strength. Dry rubber granules are then mixed to the colour ratio decided upon by the customer. Once evenly mixed, resin is added to the rubber granules and left to mix thoroughly and all granules are evenly coated with resin. The resin covered rubber mixture is then poured onto the surface and spread using a trowel to a uniform thickness, typically 3/8". When the rubber is evenly spread and level it is "closed", which means using the trowel to apply pressure to smooth the surface and ensure all rubber granules are tightly bonded to each other and the surface beneath. This process is repeated until the entire area is covered in one seamless surface.
