ABSTRACT:
A method for providing a finished joint at a corner formed between two surface members, wherein the corner includes a substantially straight portion in continuity with a curvilinear portion, comprises the steps of providing an elongate molding, applying a bonding agent to the back surface of the molding and inserting the molding into the straight portion of the corner. A gauge is provided having a contoured edge which is similar in shape to the cross-sectional shape of the face surface of the molding. A bead of caulk is applied to the curvilinear portion of the corner and is manually shaped with the gauge such that the bead of caulking and the face surface of the molding form a substantially continuous joint around the corner between the two surface members. The molding comprises an elongate strip having a face side and a back side with a rib extending from the back side. A pair of stabilizing members extend from opposite sides of the distal end of the rib. The rib and stabilizing members are dimensioned such that the plane defined by the strip edge and stabilizing member edge on one side of the rib is substantially perpendicular to the plane defined by the strip edge and stabilizing member edge on the other side of the rib. The molding is thereby insertable into a right angle corner such that the face of the molding is disposed uniformly at forty-five degrees to the two surface members despite irregularities in the joint formed between the two members.
