Abstract:
A method for beveling the edge of a first and a second wallboard panel including installation for creating a recessed flush butt joint comprising the following steps:a. cutting a first wallboard panel in a manner which produces at least one non-beveled squared edge having a first end, a second end, a bonded paper covered flat top portion, a bonded paper covered flat bottom portion and an exposed non-papered edge, with said non-papered edge being substantially at a 90 degree angle to both said top portion and said bottom portion;b. positioning a cutting instrument next to said first end of said non-beveled squared edge;c. inserting said cutting instrument into said non-papered edge;d. slicing longitudinally a continuous unwavering slot into said non-papered edge, but stopping the slicing just prior to engaging said second end of said non-beveled squared edge;e. positioning said first wallboard panel into the desired location;f. attaching said first wallboard panel to stud supports using fasteners;g. cutting a second wallboard panel into the desired size and shape in a manner which produces at least one non-beveled squared edge having a first end, a second end, a bonded paper covered flat top portion, a bonded paper covered flat bottom portion and an exposed non-papered edge, with said non-papered edge being substantially at a 90 degree angle to both said top portion and said bottom portion;h. positioning said cutting instrument next to said first end of said non-beveled squared edge;i. inserting said cutting instrument into said non-papered edge;j. slicing longitudinally a continuous unwavering slot into said non-papered edge, but stopping the slicing just prior to engaging the second end of said non-beveled edge;k. positioning said second wallboard panel next to said first wallboard panel, thus said first wallboard panel and said second wallboard panel are substantially aligned side-by-side with said non-papered edge of said first panel being substantially butted up next to said non-papered edge of said second panel;l. attaching said second wallboard panel to stud supports using fasteners;whereby:when said fasteners are affixed, compression is applied to each said non-beveled squared edge causing closure of each said slot, thus a concave recessed flush butt joint is automatically formed;and;m. applying tape and compound.
