Cav-Air-Ator® | Drainage Mat for Brick and Natural Stone Walls

Installation for Brick:

1. Install first course of brick. Remove any mortar or debris from the cavity.
2. Place the drainage mat in the cavity with the filter fabric facing out.
3. The product does not require any fasteners. It will rest on the brick ties and be friction fit in the cavity.
4. Install subsequent courses of brick, reaching the next brick tie.
5. Repeat this process continuously throughout the full-height of the masonry cavity wall.

NOTE: At the bottom of the wall and above all through wall flashings, use multiple layers if there is open airspace between the drainage mat and the brick veneer.
