Boxable drywall corner bead

An interior drywall corner bead capable of wet mudding of both sides simultaneously comprising:

• a pair of elongated flanges each with a wall facing side and a room facing side joined edge-to-edge lengthwise along a centerline, said flanges initially forming a single flat surface;
• an elongated trapezoidal nose member attached to said flanges along said centerline on said room facing side running approximately parallel to said centerline, said elongated trapezoidal nose member having a flat top running approximately parallel to said flanges, said flat top extending away from said centerline for a predetermined distance to a taper point, said flat top ending at said taper point, said trapezoidal nose member quickly joining said flanges beyond said taper point;
• an elongated groove running end-to-end along said centerline on said wall facing side of said flanges, said groove penetrating into said nose member forming a hinge;
• said flanges and said nose member bending along said hinge to form an acute angle on said room facing side, said flat top on said nose member now forming two sections, each section still approximately parallel to one of said flanges, said sections forming an acute angle on said room facing side, whereby said sections on said nose member prevent wet mud applied to one of said flanges from crossing over to the other of said flanges.

A method of wet mudding both sides of a corner bead simultaneously comprising the steps of:

• obtaining a wet mud corner bead piece, said wet mud corner bead piece itself comprising:
• a pair of elongated flanges each with a wall facing surface and a room facing surface joined edge-to-edge lengthwise along a centerline forming an acute angle between said wall facing sides;
• an elongated protruding nose member attached to said flanges along said centerline on said room facing side, said protruding nose member having an elongated tip running approximately parallel to said centerline, said tip formed by a pair of flat continuous surfaces meeting at a substantially right angle, each of said flat continuous surfaces being approximately parallel to one of said flanges respectively, said flat surfaces extending away from said elongated tip a predetermined distance to a taper point, said flat continuous surfaces ending at said taper point, said flat continuous surfaces joining said flanges beyond said taper point forming a well, said flat continuous surfaces being prepared to directly receive paint or texture, whereby said flat continuous surfaces and said well prevent crossover of wet mud from one of said flanges to the other.
• wet mudding a first of said elongated flanges with a mud dispensing box;
• wet mudding a second of said elongated flanges with said mud dispensing box while mud on said first flange is still wet, whereby said wet mud cannot cross over from said first flange to said second flange because of said protruding nose member;
• allowing mud on both of said flanges to dry;
• directly applying paint or texture to said elongated nose member and said dry mud on said flanges.
