After a proper application, the fabric will become resistant to fire, and flames will often self-extinguish after ignition.

Why choose Flamex PF?flamex pf fire retardant spray for fabric will comply with nfpa 701

When you put the right amount of a specific flame retardant with the right substrate, they make a massive difference in terms of smoke and heat release which is the principal product property in a fire. Flamex PF fire retardant spray for fabric was specifically formulated to treat porous and semi-porous fabric fibers, unlike other single fire retardants that are marketed to treat both fabric and wood which will only be mostly effective on one or the other because of the chemicals used. In other words, there are certain chemicals to fireproof wood and certain chemicals to fireproof fabric.

How to apply a fire retardant spray to fabric:

  1. Make sure that the fabric has been washed or vacuumed to remove dust.

  2. Apply with a spray bottle, an airless sprayer or by completely immersing the fabric. 

  3. If spraying, start at the upper left corner and apply the fire retardant across from end to end.

  4. Continue working your way down and across while overlapping each pass.

  5. After treating one side of the fabric, confirm that the opposite side is damp.

  6. If the first side did not penetrate through, repeat the application to the opposite side .

  7. Eliminate any folds in the fabric in order for air to dry the treatment thoroughly.

Flammability test is best to know the identification of fabric:

To recognize the composition of fabrics by the burning test, the sample of fiber, yarn, or fabric should be moved slowly towards a small flame, and the reaction to heat carefully observed. One end of the sample should be put directly into flame to determine its burning rate and characteristics. The burning odor should be noted and the characteristics of the ash such as amount, form, hardness, and color should be examined.

To identify fabric that is unknown, a simple burn test can be done to determine if the fabric is a natural fiber, man-made fiber, or a blend of natural and man-made fibers. The burn test is used by many fabric stores and designers and takes practice to determine the exact fiber content. However, an inexperienced person can still determine the difference between many fibers to “narrow” the choices down to natural or man-made fibers. This elimination process will give information necessary to decide the care of the fabric.

    I own a restaurant in California and needed to treat the curtains with a fire retardant according to fire inspector. The Flamex applied very well with no smell and no different appearance in fabric. Would use again!
