Specifically designed to produce the smoothest finish possible, RoyOMartin's GreenCore Plyform™ is manufactured with high-quality face veneers, sanded smooth, and finished with a premium reactive release agent for a high-performing, cost-effective, concrete-forming solution. GreenCore Plyform™ is designed and manufactured specifically for concrete-forming on all wall, deck, and pillar surfaces. It is pre-oiled with a premium reactive release agent, with excellent performance and multiple re-use. No special tools are required; GreenCore Plyform™ can be cut, drilled, routed, jointed, glued, fastened and finished with ordinary tools, just as you would with ordinary plywood. It reduces field repairs and produces more pours per panel with consistent job quality. GreenCore Plyform™ is user-friendly and saves time, material, and labor. As a Group 1 species, GreenCore Plyform™ is classed among the strongest and stiffest forming material in the industry. The BBOES structurally rated plyform is composed of a B-grade on both faces with C-grade inner plies cross-banded for strength. Both surfaces are fully repaired, sanded, edge-sealed and pre-oiled. As an exterior rated product, GreenCore Plyform™ is bonded with an exterior resin and designed for applications subject to permanent exposure to wet conditions. GreenCore Plyform™ panels are certified by the APA-The Engineered Wood Association-and are in compliance with APA Performance Rated Panels™ PS-107.
