ALSAN FLASHING is a unique polyurethane bituminous resin specifically formulated for liquid-applied flashings, details and maintenance applications. ALSAN FLASHING utilizes either Polyfleece or ALSAN Pre-Cut Fleece that, in combination with its unique chemistry, provides an extremely durable and easy to apply flashing solution.

Installation

Thoroughly mix ALSAN FLASHING before use. Using a brush or roller, apply ALSAN FLASHING to the prepared substrate at a rate of 2 gal/sq. Evenly coat the surface; taking precaution not to spread too thin or pool in low areas. Install the reinforcing fabric into the first layer of flashing. Add additional flashing between reinforcing fabric overlaps, to avoid dry lap conditions. With a roller or brush, embed the reinforcing fabric into the ALSAN FLASHING; eliminating any voids, ridges, air pockets, etc. Next generously apply a second layer of ALSAN FLASHING extending a minimum of 1 in beyond the reinforcing fabric, fully encapsulating the reinforcing fabric at a rate of 2 gal/sq. Once cured, apply the final coat of ALSAN FLASHING, at a rate of 2 gal/sq.
