Abstract
A method for forming a synthetic turf game-playing surface comprises, first, providing a pile carpet cover having a base sheet carrying closely spaced-apart, upright, grass-like plastic strands forming simulated grass blades. The cover is laid upon a resilient cushion pad supported upon a firm surface, and sand-like particular material is blasted against the upper portions of the blades at sufficient pressure and for sufficient time to shred the blade upper end portions into fine slivers which remain joined to their respective blades and become intertwined with adjacent slivers to form a dense mat upon the upper surface of the carpet. During the blasting, the resilient cushion beneath the carpet, resiliently supports the upright blades against being crushed or permanently compressed by the force of the blasting.
