BURN BARRIER 10 fire retardant penetrating wood treatment was developed to meet the requirements for a clear fire retardant treatment for EXTERIOR use.
BURN BARRIER™ No. 10 Product Description
BURN BARRIER™ No. 10 fire retardant penetrating wood treatment was developed to meet the
requirements for a clear fire retardant treatment for EXTERIOR use, on previously unfinished cedar
shakes and shingles. It is very effective in reducing the fire hazard of cedar and other edge grain woods.
Burn Barrier 10 contains no water soluble salts, therefore, its fire retarding properties are
lasting. Properly treated wood, when subjected to fire, will char.
BURN BARRIER™ No. 10 Application?
Apply two coats by brush, spray or by dipping. Dipping is the most effective method of treatment for
shakes and shingles, as all surfaces are treated. Allow 24 to 48 hours drying time between coats. (See
CAUTION). When applying the treatment by dipping, allow sufficient time for penetration of the
material. Burn Barrier™ No. 10 should be applied WITHOUT thinning or dilution.
150 sq. ft./U.S. gallon [3.7 m 2/L], applied in two coats at a rate of 300 sq.ft./U.S. gallon [7.4 m2/L],
per coat. NOTE: The surface area of hand split and rough textured materials is GREATER than the
apparent square footage of the area, reduce spreading rate to compensate for greater surface area.
Use Xylol, Toluene or Aromatic 100 for cleaning equipment.
Packaging: 1. gallon cans, 5 gallon pails, and 55 gallon drums.
Adequate ventilation must be provided during and after application, until the coating has dried. Avoid
breathing vapors or spray mist.
BURN BARRIER™ No. 10 PRECAUTIONS?
CAUTION! COMBUSTIBLE. The liquid coating contains PETROLEUM DISTILLATES. Due care must be
exercised during and after application until the coating is dry. Keep away from heat, sparks, and flame. Avoid contact with skin. Avoid breathing vapors or spray mist. Open windows and doors or use other means to ensure fresh air entry during application and drying. If you experience eye watering, headaches or dizziness, increase fresh air or wear respiratory protection (NIOSH/MSHA TC 23C or equivalent) or leave the area. Do not take internally. Close container after each use. Use with adequate ventilation.
NOTICE: Reports have associated repeated and prolonged occupational overexposure to solvents with permanent brain and nervous system damage. Intentional misuse by deliberately concentrating and inhaling the contents may be harmful or fatal. Consult the material safety data sheet for this product, prior to opening the container.
All exterior wood treatments and coatings are subject to deterioration when exposed to weather. In order
to insure maximum continued protection, exposed surfaces should be retreated every three to four years.
Exposure to strong sunlight will cause the wood to darken due to the nature of the fire retardant
ingredients. This darkening in no way affects or impairs the fire retardant qualities of the treatment.
Packaging: Standard packaging, 1 gallon, 5 gallon, and 55 gallon containers.
TEST METHODS: (small scale)
A cedar shingle approximately one foot square was divided in half. One section was treated with two
coats of Burn Barrier 10, at a coverage rate of 300 sq.ft./gallon, per coat. Panels were allowed to
dry 72 hours, before fire testing. The panels were placed at a 45 angle for an incline fire test. A Fisher
high temperature gas burner, having a flame temperature of 1800F, was placed two inches from the
panel surface, and the time of flame exposure measured. The flame was removed at 15 and 30 second
intervals, and the time in seconds for the panel surface to self extinguish was recorded.
