Why TOPCOAT® FireOut™ Fire Barrier Coating?

TOPCOAT® FireOut™ Fire Barrier Coating is a low VOC, water-based coating system that provides outstanding flame spread and penetration protection to combustible roof decks in the event of fire.


  • Superior Technology:  Special in-tumescent additives minimize flame spread in the event of fire
  • Provides UL Class A Performance:  In mechanically attached and self-adhered TPO, PVC, and modified bitumen systems
  • Self Extinguishing:  Active coating expands in the presence of heat or flame to form a protecting, self-extinguishing layer
  • Installs up to 130% Faster:  Simple, one step application installs in less than half the time of a gypsum board or fire resistant slip sheet application
  • Up to 43% Lower Installed Cost:  Versus gypsum boards or multiple layers of slip sheets
  • Safer Installation:  Less material on the roof, no loose edges
  • Keeps the Roof Drier:  Seamless, breathable coating will not trap water if it rains before roof membrane installation
  • Easy Application:  Choose from spray, roller, or squeegee for maximum versatility
  • Stays Flat:  Fully bonded to the substrate, can’t wrinkle, curl, or lift
  • Lightweight:  Less than 10% of the weight of recover board
