A back-blocking device and method designed to attach any thickness of drywall together at the butt ends of the panels. Butt seams are necessary because of larger ceilings and walls where using one length drywall panels is impossible. Using conventional techniques, butt seams are difficult to conceal and are subject to ridging. This device and method enables the joints to be made between the framing members by securing each end to a specially designed back-blocking. This union creates a joint that attaches the panels together, basically creating a continuous piece of drywall. The back-blocking is slightly angled down the center, at an angle of approximately 170 degrees. Each long edge of the back-blocking is thicker than the remaining back-blocking, which, combined with the slight (approximately 10 degree) difference between the 170 degree angle and a straight 180 degree angle, creates a recessed joint when the drywall is screwed along the center crease of the back-blocking, which enables the seam to be fully hidden and prevents ridging.
