FlameOFF® Coatings, Inc. manufactures and offers both a white intumescent paint tested to ASTM E-84 and ASTM E-119/CAN/ULC-S101 standards and a clear fire retardant spray tested to NFPA 701 standards.

The Wet Film Thickness (WFT) can be applied at 15-45 mils depending upon applicator experience and rating requirements. For applicators not experienced with our product we recommend applying additional coats at lessor amounts to achieve the required DFT.
