ABSTRACT:
A board for use in constructing exterior floors has a rounded or curved convex top surface to shed water, and a complementally shaped rounded or curved concave bottom surface for nesting engagement with the top surface of an adjacent board so that a plurality of the boards may be stacked in stable relationship. The radius of curvature of the rounded top surface is such that a floor formed by a plurality of the boards placed side-by-side provides a comfortable surface on which to stand and walk. In a modification, the bottom surface has a plurality of stress-relief channels formed therein to prevent cupping or warping of the board.
