Flex-Flash Flashing
Moisture infiltration can occur at sills, projections, recesses, intersections and mortar joints. The solution begins with proper flashing. H&B’s Flex-Flash™ is a 40-mil thick product formulated with Elvaloy® Kee. It does not drool and combines the best features of other types of flashing, making it a truly superior product.
Typical “peel-and-stick” flashings have a black, rubberized-asphalt component that can “drool” or leach out to the exterior of the building in warm temperatures if not precisely installed. This can leave unsightly marks that are difficult to remove. Flex-Flash™ has a pressure-sensitive, clear adhesive that will not drool when exposed to UV or heat.
Flex-Flash™ may be used in thru-wall or surface-mount applications. For surface-mount applications, apply to clean, dry surface. For surfaces where additional adhesion may be required, use H&B Foam-Tak™ Hi-Performance Spray Adhesive. Termination Bars must also be used. Flex-Flash should be extended beyond the wall face and cut flush with the brick. Optional Drip Plates may be used to effectively guide moisture to the exterior.
