The present disclosure relates a building surface accessory comprising an elongated body having a length that extends from a first end to a second end, the elongated body having an inside surface, an outside surface, a first edge, and a second edge, and an adhesive sheet having an outside surface coupled to the elongated body, an inside surface, and pressure sensitive adhesive on at least a portion of the inside surface, wherein the adhesive sheet is embossed such that the pressure sensitive adhesive has a plurality of raised portions.

Pressure sensitive adhesive building surface accessory

The present disclosure relates a joint support that includes a support strip having first and second elongate flanges, the first and second elongate flanges having an inside surface, an outside surface, an inner edge, and an outer edge. The joint support further includes a first auxiliary flap including an inner portion attached to the inside surface of the first elongate flange and an outer portion that extends laterally beyond the outer edge of the first elongate flange. The joint support further includes a second auxiliary flap including an inner portion attached to the inside surface of the second elongate flange and an outer portion that extends laterally beyond the outer edge of the second elongate flange. The joint support further includes a pressure sensitive adhesive substance disposed on at least a first portion of an inside surface of each of the first auxiliary flap and the second auxiliary flap.

Pressure sensitive adhesive joint support

The present disclosure relates generally to building surface joint supports, for example, suitable for covering a seam between two building surface panels. In certain aspects, the disclosure provides joint supports that include an elongate layered structure having inside and outside surfaces, the elongate layered structure including a support strip that includes first and second elongate flanges. In certain embodiments, the elongate layered structure also includes an inner facing sheet disposed on the inside surface of the support strip; and an outer facing sheet disposed on the outside surface of the support strip, wherein the each of the inner facing sheet and the outer facing sheet is formed from a fibrous polymer material. In other embodiments, each flange of the first and second elongate flanges includes apertures therethrough, each aperture having a width that extends laterally across at least 50% of the width of the respective flange; and the elongate layer structure also includes an outer facing sheet disposed on the outside surface of the support strip.
