Flame Seal 84 (Fireproof Paint)


Flame Seal 84 (Fireproof Paint) is latex based, intumescent paint designed for use over combustible interior materials. The product can be applied to most substrates including, wood, plywood, OSB, gypsum wallboard to increase the fire resistance.  When properly applied, Flame Seal 84 meets the ASTM E-84 class-A testing requirements for flame and smoke spread. When Flame Seal 84 is exposed to fire or extreme heat, a protective layer of Carbon Foam develops and prevents the fire and heat from transferring to the substrate.
