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. 

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.
