Flame Seal FX950 (Fireproof Paint)

Flame Seal FX950 Fire-Resistant Paint

Flame Seal FX950 is an intumescent, water-based, fire-resistant wood paint suitable for multiple surfaces, such as lumber, plywood, OSB, and Gypsum. It has undergone rigorous testing and holds a classification ranging from Class A up to a 2-hour rating, making it compliant with both domestic and international building codes, as well as standards for the Wildfire Urban Interface. When subjected to fire or intense heat, Flame Seal FX950 forms a protective layer of carbon foam, preventing the heat and flames from penetrating the underlying material. FX950 fire barrier paint is a low-VOC product that offers a slick white finish of architectural grade. You can use this product in combination with a primer and topcoat. For optimal results, Flame Seal recommends the use of an airless sprayer, as detailed in the application guide.
