<p>The corner tool (10) is for applying mastic material along a wall joint. It has a frame (12) including an angled plate (12a, 12b), elastically joined at one corner. The frame includes a pair of L-shaped elements, (13, 14) each fastened to one side of the plate, one side and element being elastically movable. There is a pair of brushing blades (16) along intersecting frame element edges. An extensible connection provides adjustment of the sides' elastic bending, and another device elastically prestresses the frame elements, to enlarge the enclosed angle, while another limits the extension movement.</p> |
