Turface SlideMaster™ is an expanded shale that can be used as a stand-alone topdressing or can be combined with industry-leading Turface calcined clays to allow you to better manage playing conditions and surface moisture. Particles are specially formulated with consistent sub-angularity to provide the ultimate sliding surface for skinned infields! The particles let water pass through to the infield skin, helping improve water management especially in hot or dry weather.
