Mortar Break® and Mortar Break® II mortar deflection mats work in conjunction with masonry flashing and our weep vents as a complete and effective moisture management system. Both products suspend excess mortar droppings above the weep holes and allow any moisture trapped within the cavity to seep down the flashing and out of the wall. The system also helps to maintain an airspace for ventilation and drying of the wall cavity.

Mortar Break® is designed to prevent mortar droppings from blocking drainage channels for 1” (25mm) masonry cavity wall applications.

Applications

For all cavity wall flashing locations including the base of the wall, above windows and doors, steel lintels, spandrels, and shelf angles, or at any other penetrations or obstructions.

A. Install mortar deflection devices as part of masonry wall construction and in accordance with manufacturer’s installation instructions.

B. Install in cavities at all through wall masonry flashings with weep holes.[locations detailed on Drawings.]

C. Place deflection strips horizontally and diagonally directly on flashings.
