Sanding and cleaning device for drywall bullnose cornerbeads

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 concave-shaped central longitudinal portion positioned between two spaced, straight, parallel guide runners disposed along longitudinal margins of said elongated body;
• a handle means extending away from said elongated body;
• a highly compressible abrasive member releasably attachable on one surface thereof to said central longitudinal portion 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 runners being substantially mateable against adjacent drywall panels on either side of the bullnose cornerbead whereby said central longitudinal portion is positioned a certain distance X from the bullnose cornerbead;
• said abrasive member having a thickness generally equal to about 2X and, when releasably attached to said central longitudinal portion, is compressed a substantial amount of the thickness 2X down to about X to establish simultaneous contact between both of said guide runners against the respective adjacent drywall panels whereby a substantial biasing pressure is thereby automatically established between said abrasive surface and the bullnose cornerbead.

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 concave cylindrically shaped central longitudinal portion evenly positioned between two spaced, straight, parallel guide runners disposed along longitudinal margins of said elongated body;
• a handle means extending away from said elongated body;
• a highly compressible flat abrasive member releasably attachable on a first surface thereof to said central longitudinal portion, said abrasive member having an exposed abrasive surface on a second surface thereof for sanding and cleaning engagement with the bullnose cornerbead and excess drywall filler compound thereon;
• said first surface assuming the cylindrical shape of said central longitudinal portion when releasably attached thereto whereupon said second surface is non-compliant in shape to that of the bullnose cornerbead;
• said guide runners, when held in simultaneous mating alignment against drywall panels on either side of the bullnose cornerbead, causing said abrasive member to be automatically compressed a predetermined substantial amount of about half of a thickness of said abrasive member whereby a substantial biasing pressure is established between said abrasive surface and the bullnose cornerbead.
