Firefree Class A (“FfA”) is a premium-quality, water-based, nontoxic, thin-film intumescent flame-retardant paint that’s fully tested to meet all ASTM E84 requirements, including ASTM E84 30-Minute Extended. This certification meets the industry standard for noncombustibility. As part of the Firefree Wildfire System, FfA can be used to improve fire protection for structures exposed to wildfires in the Wildland Urban Interface (see Firefree Exterior).

Most Economical Fire-Retardant Paint

Firefree Class A fire-retardant paint is cost efficient: because of its superior fire-resistant performance, only a relatively thin layer of FfA will be required. As a result, FfA provides significant material and labor cost reductions —savings of 35% and above—compared to costs associated with other fire-retardant coatings.

Meets All ASTM E-84 Requirements

FfA meets all ASTM E84 requirements, including ASTM E84 30 Minute Extended, meeting the industry standard for non–combustibility used to rate fire retardant treated lumber. FfA is an intumescent paint for wood listed and inspected by the International Code Council (ICC-ESR4271).

High Performance

Firefree Class A flame-retardant paint meets all of the ASTM E-84 requirements, including the 30-Minute Extended, at the recommended application rates. The addition of Firefree Class A to the line of Firefree coatings offers a cost efficient product which can be used when a fire retardant is needed to slow the spread of fire and show no evidence of significant progressive combustion even when the test is extended to a full 30-minute period over a combustible surface. Based on the results obtained from the 30 minute extended test, the wood materials tested showed minimal char damage, showing FfA’s ability to assist in maintaining the structural integrity of the wood materials in a fire.

Easy to Use and Apply

Firefree Class A is straightforward to use. FfA is top-quality, nontoxic, water-based fire-retardant paint with a smooth architectural-grade finish (white, flat), exceptional adhesion, and great longevity. In most cases, FfA will be self-priming, resulting in additional cost savings. Apply this low-odor coating easily by brush, roller, or sprayer.


Our coating products are safe and eco-friendly, with low VOCs (<36gr/liter) compared to the current EFP regulations of 250gr/liter (per ASTM 3960). This chemical exposure is even significantly below California’s limit of 50gr/liter. Users will not find a more nonflammable, nontoxic, eco-friendly product.

Usable on Various Combustible Materials

As a noncombustible paint for wood, Firefree Class A can be applied to a wide range of combustible materials and assemblies: oriented strand board (OSB), Douglas fir, plywood, dimensional lumber, wood joists and trusses, wood paneling and sheathing, and associated lumber. Recommended uses include residential, multifamily, commercial, and industrial projects. As part of the Firefree Wildfire System, FfA can be used in exterior applications, including wildfires protection, if covered by the Firefree Exterior Topcoat ("FfE").
