Joint support including encapsulated adhesive

A method of installing a joint support on a joint between a first drywall panel and a second drywall panel, the joint support comprising:

• a support strip including a width, a length in the range of 4-20 feet, a first end, a second end, a contact surface and an outer surface;
• and
• an adhesive substance disposed on the contact surface of the support strip, the adhesive substance including:
• a first set of capsules, each capsule of the first set of capsules including an outer membrane enclosing a first component of an adhesive composition,
• the method comprising:
• placing the joint support over the joint between the first drywall panel and the second drywall panel so as to cover a portion of a seam between the first and second drywall panels and with the contact surface of the joint support disposed against a surface of each of the drywall panels;
• and then
• applying a pressure to the joint support by pushing the joint support against the first drywall panel and against the second drywall panel, the pressure releasing the first component of the adhesive composition from the capsules of the first set of capsules, wherein the adhesive composition attaches the joint support to the first drywall panel and the second drywall panel,
• wherein the first drywall panel and the second drywall panel form an interior building surface.
