Abstract: A long, narrow, wedge shaped finishing member is installed secured to the underside of sheet floor covering and to the upper surface of the underlying floor structure. The wedge is relatively thick in its wall side thinning to a parallel, opposite feather edge. Butted against vertical surfaces such as bathtub sides or bathroom walls, it provides a downwardly sloping strip to drain away pooled water from the critical edge portion of the floor installation, preventing penetration and floor bonding failures.
