Abstract:
A bullnose cornerbead sanding and cleaning device for removing cured drywall filler compound from, and finish sanding of, a bullnose cornerbead which forms a lengthwise extending raised rounded corner joint between adjacent drywall sheets of a drywall installation comprising:an elongated body having a cylindrical concave-shaped central longitudinal surface positioned between two sets of spaced guide rollers disposed along both longitudinal margins of said longitudinal body each said set of rollers disposed in proximity to an end of said elongated body; a handle extending away from said elongated body; a highly compressible elongated abrasive member releasably attachable on one surface thereof, and contourable to and generally coextensive with said longitudinal surface and having an exposed abrasive surface on another surface thereof for mateable sanding and cleaning engagement against substantially only the bullnose cornerbead and drywall filler compound thereon; said guide rollers, in cooperation with said abrasive member, substantially mating against adjacent drywall panels and the bullnose cornerbead, respectively, whereby substantially only the bullnose cornerbead and drywall filler compound thereon comes into sanding contact with said abrasive layer; said abrasive member being compressed a substantial amount of a thickness thereof to establish contact between both of said longitudinal margins and the respective adjacent drywall panels whereby a substantial biasing pressure is established between said abrasive surface and the bullnose cornerbead; each longitudinal margin of said central longitudinal surface is defined by an alignment recess, said alignment recesses spaced apart a distance across said central longitudinal portion substantially equal to a width of said abrasive member to establish lateral placement of said abrasive member with respect to said guide rollers.
