摘要： A method for forming drywall joint systems wherein abutting edges of adjacent wallboard panels are adjoined by a thermoplastic adhesive substance which acquires its adhesive properties when heated and allowed to cool. The thermoplastic adhesive is applied to the joint formed by adjacent wallboard panels after they are erected or it is pre-applied and then reheated after wallboard erection. Joint systems formed according to the method may consist of the thermoplastic adhesive substance alone or with other joint-forming materials such as jointreinforcing tape and/or a cementitious adhesive.

摘要： A predecorated wallboard for forming simulated monolithic predecorated wall construction is composed of an elongated rectangular core panel including a set gypsum core enclosed on its two opposite sides and two longitudinal edges with a paper facing layer and having on its front side a flat central surface arranged between recessed marginal surfaces extending from the flat surface to the opposite longitudinal edges of the panel and tapering edgewise toward the rear side of the panel, and a decorative sheet including a cloth backing layer laminated only to the flat surface of the paper facing layer on the front side of the panel throughout the length of such front side and an outer polyvinyl chloride layer forming a decorative front wall surface, such sheet also including a narrower flap extending over one of the marginal surfaces but terminating flush with the adjacent longitudinal edge of the panel and a wider flap extending over the opposite marginal surface beyond the opposite longitudinal edge of the panel. Each wallboard is adapted to form a joint with an adjacent wallboard, such as a flat joint wherein the adjacent longitudinal edges of the panels are arranged in abutting relationship and the front sides thereof are flush, with the adjacent marginal surfaces thereof forming beneath adjacent narrower and wider flaps a shallow V-shaped recess or space to be filled to the level of the flat surfaces of the panels with a hardened joint cement layer to which the narrower and wider flaps are adhered as well as to each other in overlapping relationship over the marginal surface underlying the narrower flap, the joint being completed by cutting through the overlapping portions of both flaps, by removing the overlapping and overlapped marginal edge portions of the overlying and underlying flaps respectively to cause the narrow flap to terminate short of the adjacent longitudinal edge of the underlying panel, and by readhering the remainder of the overlying flap to cause the wider flap to extend into edge abutting and flush relationship with the narrower flap to form a practically invisible seam.
