Flame Stop® II is a water-based, post-treatment, interior/exterior fire retardant and wood preservative that penetrates the material and bonds with the cellular structure. The penetrant protects the substrate by creating a self-extinguishing reaction when the treated material comes into contact with an open flame. When properly applied on certain untreated woods, such as Douglas fir, the wood shall have a Class A rating.
Flame Stop® II contains polymers that maintain the fire retardation for up to five years for exterior applications. It is non-toxic, non-combustible, non-carcinogenic, easy to apply, and contains no PBDEs (polybrominated diphenyl ethers), which are toxic to humans and the environment.
Flame Stop® II protects exterior and interior woods such as porous woods, cedar shake shingles, decking, and structural lumber.
Flame Stop® II is a Class A, one-coat system with a flame spread of 25 and smoke developed of 25 on Douglas fir. Since this product penetrates and forms a molecular bond with the substrate, the life of the flame retardation is indefinite for most interior applications.
For exterior applications, it is recommended that Flame Stop® II be reapplied after five years. It does not alter the structural integrity of the wood the way pressure treatment does, and it is preferred because it is user-friendly, functions as a wood preservative, dries clear, and can be easily applied by spraying, immersing, brushing, or rolling. Once cured for 48 hours, the treated material may be painted with most latex-based paints.
