Flamex Fire Retardant Sprays
What is a Fire Retardant Spray?
A fire retardant spray is a protective, often water-based, clear coating (e.g., Flamex PF-2) designed to stop flame spread and reduce smoke on porous materials like wood, fabric, paper, and thatch. It is used for DIY homeowners, commercial, and school applications to meet safety codes, generally by forming a protective char barrier when heated.
