Master Flame Fire Retardant Spray 4 Gallon Case - Class A Protection

In this review the Master Flame 4 gallon case is evaluated for contractors, theater crews and facility managers who need a concentrated, spray-on solution to reduce flame spread. The bottom line: this product is best for projects that treat wood, fabrics, paper and other absorbent materials where a proven, tested retardant is required. Its chief selling point is compliance with major standards, making it a reliable choice when meeting building or event safety specs matters most.

Key Features

• Standards Tested: NFPA 255, 701 and ASTM E 84 testing provide documented performance that helps meet safety codes and regulatory requirements.
• Class A Rating: A Class A rating means treated materials show limited flame spread and smoke development, useful for public venues and installations.
• Material Compatibility: Formulated for wood, fabrics, paper and other absorbent materials, it can be applied across a variety of surfaces commonly used in sets, displays and interiors.
• Spray Application: Supplied as a spray-on system in a 4 gallon case for larger jobs, enabling continuous treatment without frequent refills.
• Non-Toxic Formula: The eco-friendly, non-toxic composition contains no PBDEs or known toxins, which reduces concerns during handling and after application.

Who It's For

The Master Flame 4 gallon case is aimed at professionals and organizations that need to treat large areas or multiple items: set designers, restoration teams, facility managers, and industrial users who must meet NFPA or ASTM standards. Its volume and spray format suit projects where throughput and consistency matter.

Users seeking a small consumer-sized solution or those prioritizing maximum adhesion to non-absorbent substrates should look elsewhere, since the product is optimized for absorbent materials and large-batch application rather than tiny, precision jobs.
