ABSTRACT:
An improved corner finishing tool for applying mastic along a wall joint and having a container that defines a cavity open in two convergent and substantially perpendicular planes, said cavity being bordered by surfaces that converge peripherally of said cavity, said container means comprising a pair of rigid retainer plates joined together by a pair of spring loaded hinges or fasteners and biased to a position of resilient flex. A pair of lever arms pivotally secured to an edge portion of the retainer plates and pivotally joined together at one end are acted upon by leaf springs which engage the lever arms at selected positions relative to the pivotal connection for adjusting the resilient flex between the pair of retainer plates. Mastic material is fed into the cavity through a socket bracket that is mounted to one of the retainer plates to which there is also mounted an alignment wheel.
