Drywall finishing strip

A corner bead for drywall construction and repair comprising:

• a flat strip with a crease extending lengthwise down the center of said strip from one end to the other, said crease providing said strip with the capability of being bent to at least about a 90 degree angle about said crease, said strip having a first inner surface and a second outer surface on opposite sides of said strip, said strip being made of mineral filled polymer, said mineral filled polymer is one which renders said first and second surfaces receptive to adhesives used in drywall construction and is selected from the group consisting of:
• mineral filled polyolefin, mineral filled vinyl, and corona treated mineral filled polyolefin, said crease being a projection extending outwardly from said second outer surface of said strip, said strip having perforations extending from said first inner surface through said strip to said second outer surface, said second outer surface of said strip having depressions formed therein, said depressions forming complementary protrusions on said first inner surface, said protrusions forming channels between said protrusions, whereby drywall compound may flow through said perforations and into said channels when said corner bead is placed over abutting pieces of drywall.
