An adjustable pre-fabricated 3-way inside drywall corner with two flat sides and a flat face to be placed in the pointed 3-way corners created where sheets of hung drywall are joined to form two walls and a ceiling. This pre-fabricated corner can be paper, metal, or other suitable material. It allows a drywall worker to string tape by starting the tape a few inches away from a corner and running to the next corner, ending a few inches away from the second corner. The worker thus does not have to gauge exactly where to cut the tape to mate into the corners. Also, the effect of tape slip while stringing becomes unimportant. After the tape and drywall mud is dry, before the finishing step, the pre-fabricated corners are placed in every corner of a room, held in place by drywall mud. A drywall worker needs only to put a small amount of topping mud on the flanges and then "kill" the corner with a 4-6 inch knife. This is done by smoothing the topping mud down the taper of the flange to form a flat, flush surface with the hung wall or ceiling board. The pre-fabricated drywall corner allows the creation of perfect 3-way corners by professionals and relatively inexperienced persons with a considerable time savings. The adjustable corner is folded to match ceilings of any rise-run angles. After the corner is folded it is typically stuck together with "peel and stick" glue. |
