Abstract
A finishing tool providing a smooth finish to taped coved joints or to corner joints having an angle greater than 90.degree. defined by converging wall board surfaces is presented. The finishing tool includes a working plate and a supporting plate, each being provided with a substantially straight edge disposed transversely to the longitudinal axes of the tool. Each of the working and supporting plates is formed of resilient material to provide longitudinal and latitudinal flexural movement so as to allow the entire length of the straight edge of the working plate to engage seam sealing material applied to the corner joint and the adjacent wall board surfaces to provide a smooth continuous finish to the corner joint.
