No. 149 Exterior Intumescent Fire Retardant Paint is a highly flexible, weather resistant, intumescent type fire retardant coating that is suitable for application to exterior surfaces where maximum fire protection is required or preferred. When exposed to fire and/or high heat, the coating intumesces (puffs up) to form a thick, dense foam fire barrier. This foam layer reduces the surface burning characteristics of combustible materials and retards the penetration of heat. For maximum durability, overcoat with Flame Control No. 400 Semi-Gloss Overcoat.
Color: White. May be tinted using not more than 2 fluid ounces of tint colorants.
Fire Hazard Classification when tested in accordance with ASTM E-84 standard.
