Abstract: A corner finishing tool for applying mastic material along a wall joint comprising an angular retainer plate having a pair of integral sides resiliently joined at a corner, a pair of L-shaped rigid frame members secured thereto, one side and frame member being resiliently movable relative to the other side and frame member while together defining a cavity reservoir for mastic material, and a wheel having substantially conical side surfaces that converge to a center rim. The corner finishing tool also provides means for setting the L-shaped rigid frame members to a preset position under an adjustable resilient biasing force.
