ABSTRACT:
A stiff plastic strip is formed to provide reinforcement for longitudinal edges at which interior drywall surfaces meet and for capping corners formed of sheets of wallboard meeting at orthogonal angles. A pair of laterally directed flanges extend in diverging fashion from a central transversely curved region of the plastic strip. A contact sensitive adhesive strip is mounted on each of the flanges to extend longitudinally therealong so as to allow the plastic strip to be pressed against drywall or wallboard surfaces. One of the flanges of the plastic strip may be slit periodically throughout its length to allow it conform to arches and circular openings. In another embodiment a stiff, water impervious plastic sheet with three flanges extending outwardly therefrom has contact sensitive adhesive layers disposed on each of the flanges. The structure can thereby serve as a cap for protruding soffit corners.
