Flannery’s Expansion Weep acts as a plaster expansion joint designed to allow for the minor movement that may occur within an exterior stucco finish. What makes the Expansion Weep unique is that it not only allows for the minor movement of the stucco finish, but it also acts as a “weeping” reveal. Flannery’s Expansion Weep assists in moving water out from behind the plaster layer of a stucco system. The upper horizontal projection (or “Ground Leg”) of the Expansion Weep is sloped to assist in draining moisture out from behind the plaster layer of the stucco system to that of a foundation weep screed. The Expansion Weep comes with a rubber gasket to help join and seal Part A and Part B together. The Expansion Weep creates a ¾” aesthetic reveal and allows for a ¼” of movement.
