Flame Stop® I is a universal fire retardant that works on most interior porous cellulotic materials. It's formula allows it to penetrate and actually become part of the wood structure, providing maximum wear and durability.
This product can be applied on any absorptive interior wood surface by either dipping or spraying the material to be treated with low-pressure equipment. The ingredients included in the formulation allow as much as 3/8" penetration into a Douglas fir stud.
Not only does this product work on wood surfaces, but can be used as an effective flame retardant on framing, fabrics, wallpaper, and other cellulotic products.
