Helps Prevent Spread From Dangerous Flames NFPA 255, 701 & ASTM E 84 tested, Class 'A' Rated Wood, Fabrics, Paper & Other Absorbent Materials Non-Toxic, Eco-Friendly -NO PBDE's or Toxins Master Flame fire retardant treats approximately 450 square feet a gallon, and is perfect for small to medium sized projects and other limited areas that need to be treated for fire protection. Master Flame is a Class 'A' fire retardant, non-toxic, eco-friendly and easy to use on a variety of materials. Master Flame forms a thermal insulation barrier that prevents dangerous flames from spreading. Master Flame also inhibits the development of toxic hydrocarbon smoke. Applications: Use to treat absorbent materials and surfaces such as drapes, curtains, decorations, uniforms, clothing, wood, pre-construction materials, furnishings, carpeting, packing materials, motor home interiors, holiday decorations, storage boxes, and other materials for added safety against fire. Basically, if it can soak into the object, it will help inhibit flames. Organic materials are best. Plastics, Styrofoam, polystyrenes and similar materials are not well protected with Master Flame. Directions: Master Flame is easy to use. Just spray Master Flame on the item or surface being treated. In bulk applications, you may also dip the items and allow to drip dry. In all applications, allow Master Flame to completely penetrate the item or surface. Allow material to dry completely. If you are using Master Flame to fire retard clothing and other fabrics it is recommended that Master Flame be reapplied after each washing; as some of the product's effectiveness will be diminished due to washing.
