BURN BARRIER™ No. 50-50 Foam Kote is a VOC compliant, water base intumescent
tire retardant paint,manufactured expressly for the thermal protection of polyurethane foam
insulation. This product is designed for use on interior polyurethane foam surfaces were it
is either necessary or desirous to reduce the burn through and flame spread rating
characteristics of the foam. It dries quickly to a flat matte finish, having the appearance of
a conventional flat paint. In the presence of heat or flame, the coating puffs up (intumescent)
and forms a thick sponge-like cellular foam layer. This foam layer insulates the foam
substrate from flames, reduces the penetration of heat, prolongs heat transfer and burn
through and reduces the surface flame spread characteristics of the foam. These combined
characteristics prolong the structural collapse of the foam composite assembly for both 2
pound and 1/4 pound sprayed foams.

For 1/2 pound foam; exceeds current "Flame Out the Front" and "Burn Through" criteria
accepted by the International Code Council (ICC), and exceeds currently proposed new
For 2 pound polyurethane foam; exceeds current "flame out the Front" and "Burn Through"
criteria accepted by the ICC*, and exceeds currently proposed flame Out the Front criteria.
*ICC is a membership association dedicated to building safety and fire prevention, developing the codes used to construct
residential and commercial buildings, including homes and schools. Most U.S. cities, counties and states that adopt codes choose the
I-Codes developed by the ICC.

Can be applied directly to fully cured polyurethane foam surfaces. If the surface is cut or shaved,
exposing the foam cells, we recommend a coat of Burn Barrier 3003 water base primer, prior to
the application of the Burn Barrier No. 50-50 Foam Kote. All surface preparation should be carried
out in accordance with good painting practices. Remove all loose, peeling or powdery
existing paint from the surface. All dirt, grease, oil, wax, and other foreign matter MUST be
removed with a detergent, rinse surface thoroughly with clear water, and allow to dry.
Burn Barrier No. 50-50 Foam Kote can be applied by brush, roller, airless or conventional heavyduty
spray equipment. Stir thoroughly and apply at approximately 200 square feet per gallon per
coat, two coats are necessary to achieve the performance characteristics referenced. If thinning is
required, use WATER only. Do not exceed 1/2 pint per gallon. Do not apply in temperatures below
Coverage Rate to achieve performance characteristics referenced below:
100 sq. ft. / gal., applied in 2 coats of ~ 200 sq. ft. / gal. each coat
See complete reports, available upon request.
Under normal conditions, dries to touch in 1 - 2 hours, can be recoated in 2 - 4 hours.
For thinning, use only clean water, maximum 1/2 pint per gallon. For equipment clean-up use
warm soapy water.
Available in white, off-white, and pastel shades, or may be field tinted with most universal
tinting colorants. Tinting colorants should not exceed 2 fluid ounces per gallon.
Standard packaging, 1 gallon, 5 gallon, and 55 gallon containers.
Do not take internally. Close container after each use. Protect from freezing.
