Overlaid concrete forming plywood is made by bonding resin-impregnated paper sheets onto one or both surfaces of specially engineered plywood panels. The resulting "overlay" reduces defects in the cured concrete by masking defects and grain patterns commonly found in non-overlay plywood. The overlay provides a smoother finish than is possible with BB Plyform or CDX sheathing. Overlays allow the plywood to be stripped easily from the concrete and permit multiple reuses of the panels as long as proper care is given to preparing and handling the panels before, during, and after the pour.
