  • the load channel for the open ceiling framing system supports the weight of the other elements and the furring channels are omega-shaped profiles used to receive the drywall in the open ceiling systems.
  • gypsum board construction methods commonly involve applying a plurality of these wall panels to said upright, thereby forming joints between adjacent gypsum board panels.
  • gypsum board panels can be quickly nailed, or otherwise fastened into place to form the wall, the seam between the individual panels usually must be concealed or “finished” before the wall can be painted or covered.
  • “Finish” refers to the task of providing a smooth, continuous finish to the joint area that is flush with adjacent drywall panels that need only be lightly sanded before painting or covering.
  • a common method of finishing or concealing such joints comprises adhering over the joint a relatively narrow strip of paper, commonly referred to as "joint tape” by means of an aqueous gypsum cementitious adhesive, commonly referred to as "plaster mud".
  • the width of the joint tape is typically slightly narrower than the dimension of the recessed area in the plane of the face surfaces of the gypsum board panels.
  • This second layer of adhesive is allowed to dry for about a day and then another thin layer of cementitious adhesive, somewhat wider, is applied over it. In this way, a final substantially monolithic or flush appearance to the wall surface is provided and the entire surface can then be lightly sanded and subsequently covered with a decorative coat of paint or the like.
  • joint finishing system used should have a smooth and substantially flat exterior surface that is substantially level or coplanar with the face surfaces of adjacent wallboard panels and somewhat wider than the tapered area of the joint.
  • Joint tape provides reinforcing strength to the joint system and prevents cracking of drywall adhesive applied over and along the joint.
  • This conventional technique for concealing or finishing drywall joints a slight ridge or bead often develops in the wall surface directly above the joint. This defect can mar the smooth appearance of the wall surface and costly repairs may be required to correct the condition.
