Master Flame Fire Retardant Spray 5 Gallon Pail - Class A Protection

In this review the Master Flame Fire Retardant Spray 5 Gallon Pail is assessed for contractors, event producers and facilities managers who need a large-volume, tested fire retardant for absorbent materials. The bottom line: it is a practical, non-toxic option when fire resistance and regulatory testing matter, delivering Class A results on wood, fabrics and paper when applied according to instructions. The review focuses on real-world application, coverage expectations, and the product's strengths and limitations for jobsite and production use.

Key Features

• Tested Performance: NFPA 255, NFPA 701 and ASTM E84 testing supports its Class A rated performance on treated surfaces.
• Broad Material Compatibility: Formulated for use on wood, fabrics, paper and other absorbent materials so a single product covers multiple job types.
• 5 Gallon Volume: The pail quantity is suited to commercial or repeated use, reducing the need for frequent refills on larger projects.
• Non-Toxic Formula: Free of PBDEs and listed toxins, making it a safer choice for indoor applications and occupied environments.
• Spray-On Application: Designed for spray application to provide relatively even coverage when proper technique is used.

Who It's For

The Master Flame 5 gallon pail is best for professionals and organizations that treat sets, large installations, or building components where Class A fire performance and certified testing matter. Contractors, theater and event teams, property managers and schools will appreciate the large volume and eco-friendly formulation for indoor or outdoor treated items.

It is less appropriate for hobbyists who need only small quantities or for projects requiring superior adhesion or rust protection on metal substrates, since the product is intended for absorbent materials and customers have reported mixed experiences with coverage and adhesion on some surfaces.
