A wall bead (100) is provided for application to adjoining surfaces, typically at a corner of a wall, during coating thereof tin with plaster or other render material. The wall bead comprises a central longitudinally extending portion (102) having first and second longitudinal edges; first and second planar panels (104, 106) extending from the first and second edges respectively; and first and second connection portions (108, 110) extending from the first and second panels respectively. The first and second connection portions each comprise a plurality of teeth (114) protruding therefrom. The first and second panels (104, 106) each comprise a flexible mesh such that they are arranged to conform to a contour of a wall surface. The wall bead is adapted to be flexible to suit the needs of varying shapes, angles and surface profiles of a wall, while having a simple and robust attachment mechanism.

A ventilation screed configured to be mounted at a vertical wall of a structure includes an attachment flange having an upper end region and a lower end region opposite the upper end region. A cavity structure is disposed along the upper end region of the attachment flange. The cavity structure has a first side, a second side, and a third side. The first side extends from the upper end region of the attachment flange. The third side extends over the first side and is spaced from the first side and from the upper end region of the attachment flange. The second side extends between the first side and the third side. At least one ventilation opening is formed through the first side of the cavity structure. A ventilation spacer extends from the first side of the cavity structure and is spaced from and extends partially along the attachment flange.

A joint strip for reinforcement of drywall panel joints as well as for a method for reinforcing panel joints i.e. around a corner of a window or door opening is disclosed.

A self-aligning corner bead for fireproofing structural steel, having a strip of welded wire fabric cut to the appropriate width for the fireproofing thickness and bent longitudinally to form an obtuse V-shaped device is disclosed. A plastic nosing is installed along one edge. A method of finishing the corners for fireproofing of structural steel member using an improved corner bead includes the step of attaching the first wing of an obtuse V-shaped device through a lathe to the structural steel member utilizing pneumatic or screw type fasteners. The mesh structure of the second wing of the V-shaped device provides a dam to form a roughened surface on the first application of fireproofing material until it hardens.

A corner trim material that is made of a material that will bond with current industry mastics such as all purpose joint compounds, resists impact, resists abrasion, and readily accepts common coatings such as drywall mud, texture and paints. The surface of this material generally does not need to be covered by any secondary fiber based material such as paper to improve bonding or coating on the inside or outside. The material generally consists of a polymer mixed with a fibrous material like pulp or glass fiber. A corner trim piece can be directly extruded from the mix. The corner trim piece can have a center hinge, can be bullnose, and the flanges can optionally have holes or optionally be coated with adhesive.

A plaster taping apparatus comprises a compartment for holding plaster taping mix and receiving a supply of tape and a removable attachment attachable to the plaster taping apparatus for applying the tape comprising the plaster taping mix exiting the compartment to a surface. The removable attachment comprises a body having a mounting member attachable to a clip arrangement on an outer wall of the compartment. The body comprises a first wheel arrangement at or towards a first end of the body for applying the tape to flat joints and a second wheel arrangement at or towards a second end of the body for applying the tape to internal joints. The plaster taping apparatus comprises an adjustment lever or dial accessible when the removable attachment is attached to the plaster taping apparatus for adjusting a thickness of the plaster taping mix coating the tape.

A drywall trim for protecting drywall can include a metal body having a seam with a longitudinal axis. The metal body can include wings or planar portions that extend from the seam in transverse directions relative to the longitudinal axis. The planar portions can be formed at an angle relative to each other. At least one of the planar portions can have an outer edge that is not parallel to the seam. Paper can be bonded to the metal body.

A vented stop bead and a vented weep screed are used to vent a stucco or plaster wall. The vented stop bead has a base panel with a stop bead wall extending from the base panel at a first location and a spacing member wall extending from the base panel at a second location, wherein a spacing member is connected to the spacing member wall. A vented portion is positioned between the stop bead wall and the spacing member wall, wherein the vented portion has a venting structure positioned through the base panel between the first and second locations. The vented weep screed has a nailing fin with a first leg extending therefrom at a first location. A second leg extends from the nailing fin at a second location, the second leg having at least one venting structure positioned through the second leg.
