Abstract: The present disclosure relates generally to building surface joint supports, for example, suitable for covering a seam between two building surface panels, such as drywall. The present disclosure relates more particularly to a joint support including an encapsulated adhesive for securing the joint support to the building surface panels. The joint support includes a support strip having a width, a length, a first end, a second end, a contact surface, and an outer surface. An adhesive is disposed on the contact surface of the support strip. The adhesive includes a first set of capsules and each capsule of the first set of capsules includes a membrane enclosing a first component of an adhesive composition.
