High Performance Fire Resistant and Flame Retardant Paints

FIREFREE EXTERIOR SYSTEM TECHNICAL

The Firefree Exterior System requires the use of two components.

FfA Fire Retardant Coating
  • Coating thickness: (2) coats @ 10 mils dry each; total 20 mils dry. Net coverage rate with the two coats specified: 53 sq.ft/gal (1.30 m2/l).
FfE Exterior Topcoat
  • Coating thickness: (2) coats @ 3 mils dry each; total 6 mils dry. Net coverage rate with the two coats specified: 110 sq.ft/gal (2.70 m2/l).

FfE is a premium, 100% acrylic, exterior satin paint. FfE on its own does not have any fire retardant properties. FfE must be used over the Firefree line of intumescent coatings to improve the durability of such products if used in exterior applications in strict compliance with Firefree’s recommendations.

The Firefree intumescent coatings, FfA or Ff88, must be applied to the recommended uniform dry film thickness specified by Firefree in order to meet the levels of fire retardant protection specified by the ASTM E-84 30 Minute Extended.

The Firefree Exterior System is a two-part system using the FFA fire retardant coating as a base coat to be applied to the exterior wall, eave, soffit and other projections of building structures then top coated with the Ff Exterior TopCoat.

The Ff Exterior System (FfA top coated with FfE) has been tested to the ASTM E-84 30 minute extended test standard on 5/8” T-111 Douglas Fir siding. The ASTM E-84 extended 30 minute fire test standard meets the requirement for ignition resistant materials and is the same test standard used to rate chemically treated, fire rated lumber. The Ff Exterior System has also been tested by Firefree to methods similar to the ASTM D 2898 Method B weatherization test with follow up fire testing to the ASTM E 1623 I-Cal.

Firefree Class A is listed under LEED compliant paints and coatings in accordance with CDPH Standard Method v1.2, 2017 emissions. It should be noted paints earn LEED v4 Emitting Materials credit for being emission certified in addition to meeting CARB SCM 2007 VOC limits.

Fire Safety. For various reasons, including (i) the very different circumstances that may exist from one fire to another, (ii) the differences between conditions in an actual fire and laboratory conditions in which testing is conducted, and (iii) the inherent variability of fire tests, passing a laboratory test or certifying/labeling the Firefree Exterior System (“FES”) for use in specific assemblies/systems does not mean that the same application of the FES will necessarily provide an equivalent protection or the same result in an actual fire or in a new laboratory test. Furthermore, the FES is to be used only as a component of complete fire retardation systems for the whole structure. It will only contribute to slowing fire spread for the area where it has been applied and will not, by itself, prevent a fire from starting or continuing. The amount by which the FES retards a particular fire will depend, among other things, on (i) strict compliance with Firefree’s recommendations, (ii) the conditions of the other elements of the assembly incorporating the FES, and (iii) the conditions of the actual fire itself. The FES will not make a fire any less dangerous to persons or property. Firefree cannot guarantee that loss or injury will not be suffered by persons or property. It is the sole responsibility of the applicator to ensure that FES has been applied in accordance with the application directions. It is the responsibility of the occupier to ensure the paint is not cracked, chipped or peeling.
