Flamex PF Fireproofing Spray for Fabric
Untreated curtains, drapes, and upholstery act as rapid fuel sources during a fire. A small spark can engulf a room in seconds, putting lives and property at immediate risk. Flamex PF stops this dangerous chain reaction. This water-based fire retardant spray penetrates porous and semi-porous fabrics to drastically reduce their combustibility. When exposed to high heat, Flamex PF reacts instantly to create a carbonaceous char—a blackened barrier that cuts off the fire’s fuel source and prevents flames from spreading.
Professional-Grade Protection Without Compromising Aesthetics
Treating your interior textiles must not ruin their look or feel. Flamex PF dries completely clear and leaves no stiff residue behind. You can apply it to cotton, wool, and synthetic fabric blends without worrying about dark stains or unwanted color changes. It preserves the natural drape and texture of your materials while silently providing a critical layer of passive fire protection.
Certified Safety for Your Building
You cannot rely on unverified fire sprays when occupant safety is on the line. Building codes require strict adherence to proven fire resistance metrics. Independent testing laboratories evaluate Flamex PF to ensure it performs under extreme conditions. It fully complies with stringent industry standards, including NFPA-701 and CA Title 19 1237.1. Applying this certified saturant ensures your home, theater, or commercial space meets essential fire codes and passes necessary fire marshal inspections.

FAQ’S
What is Flamex PF and what does it do to fabric?
Flamex PF is a water-based fire retardant spray formulated specifically for porous and semi-porous natural and semi-synthetic fabrics. It reduces textile flammability and slows flame spread by penetrating deep into the fibers and creating a carbonaceous char when exposed to heat — cutting off the fuel source before fire can take hold.
Flamex PF is tested and verified by SGS Laboratories to meet NFPA 701 and CA Title 19 1237.1 — two of the most widely recognized fire safety standards for fabric in the United States. Once applied correctly, it provides professional-grade fire resistance without altering the color, texture, or appearance of your fabric.
How does Flamex PF actually stop fabric from catching fire?
When heat or flame contacts Flamex PF-treated fabric, the formula releases nitrogen and rapidly forms a carbon char on the textile surface. That char cuts off the oxygen supply and removes the fuel source—stopping flame spread before it escalates.
This chemical reaction happens at the point of ignition, which means treated fabric will self-extinguish rather than sustain a flame. The process works across a wide range of natural and semi-synthetic textiles, including:
- Cotton and cotton blends
- Wool
- Many decorative and upholstery fabrics
- Stage curtains and theater drapes
What fabrics can I use Flamex PF on, and which ones should I avoid?
Flamex PF fireproofing spray for fabric works on porous and semi-porous fabrics, including cotton, wool, and many semi-synthetic blends commonly used in curtains, upholstery, costumes, and stage drapes. It is not compatible with natural silk or non-porous synthetic textiles — applying it to these materials will not produce reliable fire resistance.
Before treating a full piece, test Flamex PF on a small, inconspicuous area first. This confirms compatibility and lets you check that the formula penetrates correctly without affecting the fabric’s appearance. If the fabric absorbs the liquid evenly and dries clear, it is suitable for a full treatment.
Does Flamex PF comply with NFPA 701 and other fire safety standards?
Yes. Flamex PF is laboratory tested and verified to comply with NFPA 701 (Flame Propagation Testing for Textiles and Films) and CA Title 19 1237.1 (California Code of Regulations for flame retardancy). These tests are conducted by SGS Laboratories, an internationally accredited testing body.
These certifications mean treated fabrics meet the flame-retardancy requirements enforced in commercial buildings, public venues, and many residential applications across the United States.
- NFPA 255 (Standard Method of Surface Burning)
- NFPA 701 (Flame Propagation Testing)
- UL 723 (Standard for Test of Surface Burning Characteristics)
- CA Title 19 (California Code of Regulations
Is Flamex PF safe to use in schools, homes, and theaters?
Yes. Flamex PF is non-toxic, non-carcinogenic, and odorless once dry. It is safe for use in occupied buildings, including schools, residential spaces, and high-traffic commercial venues such as theaters and event halls.
Unlike older halogenated fire retardant formulas — which are being phased out due to toxicity concerns — Flamex PF is a modern, water-based product that releases no harmful fumes during or after application. It poses no risk to humans or animals when used as directed.
How do I apply Flamex PF to stage drapes?
A. To apply Flamex PF effectively, follow these steps:
- Make sure that the material has been washed or vacuumed to remove dust.
- Apply with a device that’s capable of spraying a thin liquid or by completely immersing it.
- When applying, start in the upper left corner and apply Flamex PF across from end to end.
- Continue working your way down and across while overlapping each pass.
- After treating one side of the material, confirm that the opposite side is damp.
- If the first side did not penetrate, repeat the application to the opposite side, especially on thicker material.
- Eliminate any folds in order for air to dry the treatment thoroughly.
- Do not use on fully synthetic/non-porous textiles.
How long does Flamex PF last, and when do I need to reapply it?
Under undisturbed conditions, a single treatment can last the lifetime of the fabric. Flamex PF bonds deep into the fibers and does not wash off through normal use — but certain cleaning and handling practices will break down the treatment over time.
Reapplication is required after:
- One wet wash — water-soluble fire retardants are removed by laundering
- Two dry cleanings — dry cleaning solvents degrade the treatment
- Heavy handling or frequent vacuuming — repeated mechanical abrasion reduces effectiveness
To maintain compliance in regulated environments — such as theaters, event spaces, or commercial venues — document each treatment date and schedule reapplication after any cleaning. Flamex PF has a shelf life of up to five years when stored between 40°F and 110°F.
Additional Information:
Flamex PF offers a shelf life of up to 5 years when stored correctly (40-110° F). It is designed to be odorless, non-toxic to humans and animals, and releases no harmful fumes. The treatment dries quickly, leaves no residue, and will not alter the color or appearance of the treated material. It meets key standards: NFPA 255, NFPA 701, UL 723, and CA Title 19 1237.1.
