Abstract
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.
Claims16
A building surface construction using a joint support, the building surface construction comprising:
- a first building surface panel;
- a second building surface panel adjacent to the first building surface panel so as to form a joint between an edge of the first building surface panel and an edge of the second building surface panel;
- an inner layer of joint compound covering the joint and extending over a portion of the first building surface panel and a portion the second building surface panel, the joint compound comprising at least 50 wt % calcium carbonate;
- and
- a joint support adhered to the inner layer of joint compound, the joint support comprising:
- 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, wherein the inner surface of the support strip is formed by paper and has a critical wax strength number of at least 18;
- and
- an inner layer of adhesive distributed over the inner surface of the longitudinal support strip and bonded to the inner layer of joint compound, the adhesive of the inner layer comprising a polysaccharide.
A building surface construction using a joint support, the building surface construction comprising:
- a first building surface panel;
- a second building surface panel adjacent to the first building surface panel so as to form a joint between an edge of the first building surface panel and an edge of the second building surface panel;
- an inner layer of joint compound covering the joint and extending over a portion of the first building surface panel and a portion the second building surface panel;
- and
- a joint support adhered to the inner layer of joint compound, the joint support comprising:
- 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, wherein the inner surface of the support strip is formed by paper and has a critical wax strength number of at least 18;
- and
- an inner layer of adhesive distributed over the inner surface of the longitudinal support strip and bonded to the inner layer of joint compound, the adhesive of the inner layer comprising a polysaccharide.
A building surface construction using a joint support, the building surface construction comprising:

- an inner layer of joint compound covering the joint and extending over a portion of the first building surface panel and a portion the second building surface panel, the joint compound comprising at least 50 wt % calcium carbonate;
- a joint support adhered to the inner layer of joint compound, the joint support comprising:
- 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;
- and
- an inner layer of adhesive distributed over the inner surface of the longitudinal support strip and bonded to the inner layer of joint compound, the adhesive of the inner layer comprising a polysaccharide;
- and
- an outer layer of joint compound disposed over the joint support, the joint compound of the outer layer comprising at least 50 wt % calcium carbonate,
- wherein the joint support further comprises an outer layer of adhesive distributed over the outer surface of the support strip and bound to the outer layer of joint compound, the adhesive of the outer layer comprising a polysaccharide.
