BLACK FLASH Flashing Cement Compound is a superior compound used for sealing around flashings and chimneys, repairing leaks in roofs, gutters and old flashings.  It is an all-weather sealant made of only the highest quality, tough plastic asphalt oils with long-fibers.  Non-hardening; BLACK FLASH stays pliable in any weather.  Can be applied to damp surfaces; never pulls away from the joint.  Won’t crack at any temperature. 

Available in a caulk cartridge or bulk.  Can be applied with putty knife or trowel.  Works well to seal and fill in holes, cracks and crevices to create a permanent seal.  Its excellent adhesion ensures that all entrapped air is eliminated.  Tools can be easily cleaned with common petroleum solvents.
