Flamex PF-1 interior fireproofing spray is specifically formulated for interior wood, paper, and straw. When the treated material is subjected to an open flame, Flamex PF-1 will reduce the flame spread depending on application coverage. Non-toxic and non-hazardous to the environment and easy to apply.

If Flamex PF-1 is applied to interior wood, the wood substrate being extinguished is cooled down by the thermal endothermic reaction and produces extinguishing water that does not evaporate as quickly as regular water does. The burning material therefore, can be wetted more effectively, making it easier to contain the fire and avoiding the high temperatures that normally occur with a fire.

When catching fire, the treated wood is immediately cooled, and therefore will not burn and cannot be ignited easily. Extinguishing water becomes chemical water that contains a nitrogen and oxygen mixture and forms a gas that replaces the surrounding oxygen which a fire needs to survive. Applying Flamex PF-1 interior fireproofing spray to wood penetrates and becomes part of the substrate.

The life of the flame retardant is permanent as long as it is applied in a humidity-controlled environment. If the interior humidity cannot be sustained at 70% or below, we recommend using Flamex PF-2. Flamex PF-1 interior fireproof spray will not alter the structural integrity of the wood. Flamex PF-1 is often chosen because it’s reputation as a flame retardant for interior use. It is non-toxic, dries clear, and is easy to apply with a sprayer. Once cured (12 hrs.) the treated material may be painted with latex paint. Use only solvent-based, non-flammable clear coats or latex based top coat. APPLICABLE STANDARDS: Flamex PF-1 has been tested to the following standards: ASTM E-84NFPA 255, and UL 723
