Installation Overview
- Where necessary, typically around playground perimeter and on playground equipment poles, mix urethane binder 1 to 1 with M.E.K. (Methyl Ethyl Keytone) or use 100% urethane to prime.
- Mix SBR granules and urethane binder in a ratio (by weight) of 88% granules to 12% binder.
- Trowel mixture over base, applying at a rate of approximately 31 lbs. 13 oz. total weight per cubic foot. Determine thickness (in inches) of base mat and divide by twelve to compute weight per square foot. Allow to cure.
- Mix urethane binder 1 to 1 with M.E.K., or apply 100% urethane binder, and prime base mat. If base mat is tacky when top surface is applied, there is no need to prime.
- Mix EPDM granules and urethane binder in a ratio (by weight) of 82% granules to 18% binder.
- Trowel mixture over base mat, applying at a rate of 2.44 lbs. per square foot.
