The present disclosure relates generally to building surface joint supports, for example, configured to bridge and support the seam between two building surface panels. The present disclosure relates more particularly to a joint support configured to support a joint between building surface panels. The joint support includes a longitudinal support strip including a first end, a second end, a first side edge, a second side edge, an inner surface, and an outer surface. An inner layer of adhesive is distributed over the inner surface of the longitudinal support strip and is configured to bond with a joint compound. The adhesive of the inner layer includes a polysaccharide.

The present disclosure relates generally to wallboards, for example, suitable for use in constructing internal walls. The present disclosure relates more particularly to a wallboard and a method that provides simplified high-quality surface finishing. The wallboard includes a wall panel having a front surface and a rear surface. A sandable coating is disposed on the front surface of the wall panel. The method includes positioning wallboards adjacent to one another, applying sandable joint compound over joint formed between the wallboards, and sanding the joint compound and the sandable coating of the wallboards.

Expanded metal lath products, or non-metal facsimile products, are disclosed with moisture resistant pressure sensitive adhesive covered by release sheets, and the use of such products in drywall seaming and their manufacture.

Devices and methods covering a gap between an edge of a surface and a body exposed through an opening in the surface defined by the edge. Such a device has at least first and second sections formed of different materials. The device is positioned so that the second section is over a portion of the surface adjacent the opening and the first section extends over the gap and the opening. After removing a release liner releasably secured to a backside of the first section to cover an adhesive, portions of the first section are bent and molded to plastically conform the portions to the edge of the surface while the second section remains over the portion of the surface adjacent the opening. The body is then contacted with the backside of the first section such that the backside of the first section is adhered to the body with the adhesive.

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.
