Title
(EN) PREDECORATED WALLBOARD JOINT AND METHOD OF JOINING PREDECORATED WALLBOARDS TO FORM A CONCEALED JOINT
(FR) JOINT DE PANNEAUX MURAUX DECORES D'AVANCE ET METHODE DE JOINTOIEMENT PERMETTANT D'OBTENIR UN JOINT INVISIBLE
Abstract
(EN)
A wall formed from square edge predecorated wallboards and the method of constructing a seamless wall from square edge predecorated wallboards (10) comprising folding the edge flaps of two abutting square edge wallboards (10) away from the joint, cutting a groove (G) along the length of the joint formed by the square edge abutting wallboards (10), adhering a joint strip (30) comprising a rib (34) which fits within the groove (G) and a support strip (32) therefore which extends laterally over the un- covered portion of each gypsum board adjacent to the joint, and double-cutting and adhering the edge flaps of the wallboards (10) to the joint strip (32) so as to form a seamless appearing joint.
