the method comprising:
providing the joint support, wherein the pressure sensitive adhesive substance is configured to transition from having a first adhesive strength configured to form a releasable adhesive bond between the joint support and a building surface to having a second adhesive strength upon application of pressure, the second adhesive strength configured to form a permanent adhesive bond between the joint support and the building surface, and wherein the joint support is provided with a release liner disposed on an inside surface of the pressure sensitive adhesive substance;
removing the release liner to expose the pressure sensitive adhesive substance; then
placing the joint support over the first building surface panel and the second building surface panel so as to cover at least a portion of the seam between the first and second building surface panels and to adhere the inside surface of the first auxiliary flap to an outside surface of the first building surface panel via the pressure sensitive adhesive substance with a releasable adhesive bond; and then
applying pressure to the joint support to adhere the inside surface of the first auxiliary flap to an outside surface of the first building surface panel via the pressure sensitive adhesive substance with a permanent adhesive bond.
6 . The method according to claim 5 , wherein the corner is a flexible hinge that connects the first elongate flange to the second elongate flange.
7 . The method according to claim 5 , wherein the first elongate flange tapers so as to decrease in thickness toward the outer edge of the first elongate flange, and wherein the second elongate flange tapers so as to decrease in thickness toward the outer edge of the second elongate flange.
8 . The method according to claim 5 , wherein the facing sheet is a paper facing.
9 . The method according to claim 5 , wherein the first auxiliary flap is formed of paper.
10 . The method according to claim 5 , wherein the support strip is formed of plastic.
11 . The method according to claim 5 , wherein the joint support is a corner bead.
12 . The method according to claim 5 , wherein the first and second building surface panels are drywall panels.
13 . The method according to claim 5 , wherein the first building surface panel and the second building surface panel are disposed at an angle of about 90°.
14 . The method according to claim 5 , further comprising coating the outer surface of the facing sheet of the joint support with a joint compound.
15 . The method according to claim 5 , further comprising covering the joint compound with a layer of paint.
16 . The method according to claim 5 , wherein the pressure is initially applied to the inner portion of the first auxiliary flap and then applied to outer portion of the first auxiliary flap.
