Tough Jobs Made Seamless

Firestone Building Products UltraFlash Two-Part Liquid Flashing is a tough, two-component liquid-applied urethane elastomer that provides a liquid flashing solution for asphaltic roofing systems. It can be used for difficult or irregular shaped roof flashings and details, where it is difficult to apply waterproofing membranes. It can also be used for any vertical flashing details. UltraFlash Two-Part Liquid Flashing is ready to use after thoroughly mixing Part A and Part B and can be used on SBS and BUR systems. When properly installed with UltraFlash Fabric, UltraFlash forms an impermeable, monolithic and seamless membrane.
