Master Flame Fire Retardant Spray - 1 Gallon Pump Sprayer

In this review the Master Flame Fire Retardant Spray is examined as a practical option for contractors, theater technicians and property owners who need to reduce flammability on absorbent surfaces. The single biggest reason to consider it is its tested fire performance: the formula is NFPA 255, 701 and ASTM E 84 tested and achieves a Class A rating, which means it reliably helps prevent spread from dangerous flames when applied to wood, fabrics, paper and similar materials. This review focuses on real-world use, coverage, and application notes based on product details and customer feedback.

Key Features

• Tested Performance: The product is NFPA 255, 701 and ASTM E 84 tested, giving users confidence in its fire retardant capability for code-aware projects.
• Class A Rated: Class A rating indicates top-level flame spread resistance useful for public spaces, sets and installations where safety matters.
• Broad Substrate Use: Formulated for wood, fabrics, paper and other absorbent materials so one product covers multiple needs on a job site.
• Non-Toxic Formula: The spray is non-toxic and marketed as eco-friendly with no PBDEs or other listed toxins, reducing health concerns during application.
• Ready-to-Use Packaging: Supplied in a 1 gallon container with a pump sprayer for easier application over larger areas compared with aerosol cans.

Who It's For

The Master Flame spray is best for professionals and DIY users who need a credible, tested fire retardant for absorbent materials: stage and set builders, restoration crews, carpenters sealing wood trim, and facilities managers treating drapery or temporary signage. It suits situations where Class A performance and recognized testing standards matter.

Those who need a permanent structural adhesive, rust protection, or a product for non-absorbent surfaces should look elsewhere, since this formula is designed for absorption into porous substrates and customers have noted variation in adhesion and coverage when many coats are required.
