Most fabrics made of natural fibers can be effectively treated using Rosco Flamex NF. Among the many fabrics commonly used in scenery or costumes, use Flamex NF on cotton, muslin, scrims, cotton netting, natural velours, wools, linens, natural felts, and most other decorative, garment or upholstery fabrics made with natural fibers.  Easy to use, with no greasy after effects, Flamex NF is the best solution for insuring your scenery and props meet local fire regulations.

Rosco Flamex NF has been premixed and does not require any further dilution.  The method of application and the amount of Flamex required for sufficient treatment varies with the fabrics in use.

One gallon of Flamex NF will treat approximately 500 square feet (46.4 square meters) of fabric.

Applying Flamex:

  • Dipping: This is the most efficient method of impregnation. Immersecompletely for ten minutes, and hang to dry.
  • Brushing: Using a wide lay-in brush, brush the Flamex solution into thefibers of the material being treated. Brush in the solution using acriss-crossing pattern to insure adequate absorption.
  • Spraying: In a spray application, it is very important that an adequateamount of the Flamex be absorbed. In calculating the amount of solutionneeded, remember that a substantial portion of the spray will not fall on thefabric. Use a Hudson-type sprayer with a medium nozzle setting. For bestresults, hang the material to be treated and spray in a back and forth patternstarting at the bottom and working your way up to the top of the fabricsample.

Over saturating the fabric may cause it to stiffen or otherwise alter its hand.  ALWAYS treat a test sample to determine how the fabric will react and to test for effective flame retardance.

Flamex NF has been approved for use by the California and New York City Fire Marshall and has been tested according to NFPA 701.

Store Flamex products in non-metallic containers.  When metal sprayers are used, they should be thoroughly cleaned immediately after use, including nozzles and accessories.  Avoid use of metal buckets or paint containers when possible.
