Abstract
A wall formed from square edge predecorated wallboards and the method of constructing a seamless wall from square edge predecorated wallboards comprising folding the edge flaps of two abutting square edge wallboards away from the joint, cutting a groove along the length of the joint formed by the square edged abutting wallboards, adhering a joint strip comprising a rib which fits within the groove and a support strip therefor which extends laterally over the uncovered portion of each gypsum board adjacent to the joint, and double-cutting and adhering the edge flaps of the wallboards to the joint strip so as to form a seamless appearing joint.
Claims19
A method of joining a pair of predecorated square edge wallboards so as to conceal the joints therebetween without the use of battens and the like comprising:
- providing a pair of predecorated square edge wallboards (10) each having a predecorated sheet (12) adhered to the major central portion of the face of the undecorated wallboard (14)and wherein the predecorated sheet is not adhered adjacent to the side edges of said wallboard and extends beyond the side edges thereof to form edge flaps;
- attaching said wallboards (14) in adjacent relationship to wall studs or the like (20), said wallboards of the type each having a predecorated sheet (12) adhered to the major central portion of the face of the undecorated wallboard and wherein the predecorated sheet is not adhered adjacent to the side edges of said wallboard and extends beyond the side edges thereof to form edge flaps;
- pulling said adjacent edge flaps of said predecorated wallboards back to expose the joint between said adjacent wallboards and the surface area of undecorated wallboard adjacent to the side edges thereof;
- cutting a groove (G) alone at least a substantial portion of the length of the joint (J) between said pair of adjacent wallboards and within the square edges of said adjacent wallboards;
- adhering a joint strip (30) over at least a substantial portion of the length of said groove, said joint strip comprising a rib along the length thereof adapted to matingly fit within said groove and a support strip secured thereto which extends laterally over at least a portion of the undecorated wallboard adjacent to the side edge of each of said adjacent wallboards;
- releasing said edge flaps of said adjacent predecorated wallboards and positioning said flaps in overlapping relationship;
- and
- removing overlapping portions of said edge flaps and adhering said remaining portions of said edge flaps to said joint strip to form a smooth surface.
A predecorated wall comprising:
- a pair of adjacent predecorated square edge wallboards (10) having edge portions forming a joint (J) therebetween, said wallboards of the type each having a predecorated sheet (12) adhered to the major central portion of the face of the undecorated wallboard (14) wherein the predecorated sheet is not adhered adjacent to the side edges of said wallboard and extends beyond the side edges thereof to form edge flaps;
- a groove (G) provided within the square edges of said pair of adjacent wallboards along at least a substantial portion of the length of the joint formed therebetween, said groove having been cut in said wallboard joint subsequent to said square edge wallboards being in position;
- a joint strip (30) adhesively secured to said groove and comprising a support strip which extends laterally over at least a portion of the undecorated wallboard adjacent to the side edge of each of said abutting wallboards and a rib along the length thereof adapted to matingly fit within said groove;
- and
- a smooth seam formed over said joint strip by said flaps having been suitably double-cut and adhesively secured thereto.
