Flamort 6-3
Fire Retardant Coating Clear No. 6-3
(For Interior Only)
CA. REG. #C-00416

Flamort 6-3 is a clear and colorless surface impregnation for application on interior surfaces of unpainted wood and plywood to REDUCE FLAME SPREAD and SMOKE when exposed to fire. Flamort 6-3 does not contain Halogen or Sulfur compounds (Chlorine less than 0.005% by wt.; Sulfur less than 0.020% by wt.)

Surface impregnation by spraying allows Flamort 6-3 to penetrate into the surface of the wood. Application shall be with conventional low-pressure air, air-less, or orchard type paint spray equipment. Spray uniformly over the entire surface using a coarse nozzle (T-jet style nozzle may be used). Protect metal and other surfaces, which may be affected by contact with the Flamort 6-3 over spray. Apply two (2) coats of Flamort 6-3, each coat at 200 sq. ft. coverage per gallon, with at least 24 hours drying time between coats. Proper drying conditions of temperature and humidity are necessary. Treated surfaces may be left unfinished, stained, painted, or coated with a varnish or lacquer (non-water base type). If any residue appears on the surface, sand and wipe clean before applying the finish coat. All equipment should be cleaned with water. Before finish system is applied, moisture content of flame retardant wood must not exceed 12% and must be stabilized at least four (4) days.

Treating a test sample is recommended to ensure compatibility with finishes. We are available for consultation should you require help in selecting compatible finishes.

Flamort 6-3 is furnished as a ready-to-use coating in one (1) gallon and five (5) gallon containers. ASTM E84-80 rating: Flame Spread - 25 Class 1-A Smoke Density 5.
