Flamex PF Fireproofing Spray for Fabrics & Upholstery

Protect your indoor environments, public venues, and commercial textiles from rapid ignition with Flamex PF fabric fire retardant spray. Untreated curtains, drapes, and furniture act as fast-burning fuel sources during emergencies. Flamex PF halts this dangerous reaction. This professional-grade, water-based saturant penetrates deeply into porous and semi-porous natural and synthetic fibers. When exposed to extreme heat, the formula instantly releases nitrogen to create a thick carbonaceous char, cutting off the oxygen supply and forcing the material to self-extinguish.

Designed for commercial compliance and residential peace of mind, Flamex PF ensures your property satisfies strict local fire codes. It is laboratory tested and verified by SGS Laboratories to fully comply with NFPA 701 (Flame Propagation Testing for Textiles and Films) and CA Title 19 1237.1 standards. It dries completely odorless, clear, and flexible, ensuring treated materials maintain their original color, texture, and natural drape without stiff residue.

Key Features & Specifications:

  • NFPA 701 Certified Fabric Spray: Verified by accredited third-party labs to meet strict US building and event space fire codes.

  • Invisible Thermal Barrier: Dries completely transparent and clear; will not stain, discolor, or stiffen delicate textiles.

  • Eco-Safe & Non-Toxic Formulation: Non-hazardous water-based chemistry that releases zero harmful fumes or halogenated gases.

  • Versatile Substrate Penetration: Ideal flame retardant spray for curtains, theater stage drapes, banners, clothing, and high-traffic upholstery.

Formulated For Excellence

Why Professionals Specify Flamex PF

Unlike typical solvent-based treatments, Flamex PF penetrates deep into fabric fibers without changing hand feel, color depth, or drape aesthetics.

Zero Stiffening or Residue

Maintains original textile texture and softness. Leaves zero powdery film, crystalline residue, or stiff crusting when dry.

  • Invisible matte drying formula
  • Preserves luxurious fabric drape

Instant Self-Extinguishing

Reacts thermally to open flame by releasing flame-suppressing inert gases and generating an insulating carbonaceous char barrier.

  • Prevents progressive flame spread
  • Extinguishes within 1.2 seconds of flame contact

Non-Toxic & Eco-Conscious

Free of hazardous polybrominated diphenyl ethers (PBDEs), halogenated additives, heavy metals, and harsh petroleum solvents.

  • Safe for occupied indoor venues
  • Zero VOC, water-based solution
Textile Compatibility

Approved Fabric Classifications

Flamex PF requires an absorbent substrate to absorb the flame retarding polymers. Review our compatibility guide before spray application.

Recommended Fabrics (Ready to Treat)

Cotton, Muslin & Canvas

Exceptional penetration. Ideal for stage backdrops, theatrical velour, and draperies.

Linen & Natural Burlap

Absorbs quickly without altering fiber color, grain, or natural texture.

Rayon & Viscose Blends

Cellulose-based synthetics readily absorb the flame retardant barrier.

Wool & Wool Blends

Provides superior protection for high-traffic hotel draperies and acoustic wall panels.

Absorbent Polyesters & Blends

Standard poly-cotton blends (up to 50/50 ratio) achieve complete NFPA 701 compliance.

Special Considerations & Incompatibles

100% Non-Porous Hydrophobic Synthetics

Non-absorbent 100% nylon or sealed ripstop fabrics require pre-wetting or specialized surfactants.

Scotchgard™ or Teflon™ Treated Fabrics

Existing water repellents must be professionally stripped before Flamex PF can absorb.

Metallic Sheen Fabrics & Foils

Conduct a small patch test on metallic threads to verify no surface oxidation occurs.

Dry Clean Only Water-Sensitive Silks

Perform water spot testing before complete immersion or heavy misting.

How to Apply Flamex PF to Fabric

Follow these four straightforward steps to achieve fire marshal inspection certification on any project.

1

Clean & Inspect

Ensure the textile is completely dry and free of oils, sizing, or dirt. Perform a spot test on an inconspicuous seam for colorfastness.

2

Spray Application

Apply Flamex PF using a standard low-pressure pump sprayer or fine mist gun at 12–18 inches distance. Coat evenly until damp but not dripping.

3

Natural Dry

Hang or lay flat in a well-ventilated space. Dries thoroughly within 2 to 4 hours at ambient indoor room temperatures.

4

Certify & Document

Clip a small border swatch and conduct a flame test. Issue your Certificate of Flame Resistance for local Fire Marshal inspection.

Common Questions

Frequently Asked Questions

Everything you need to know about fabric flame retardant regulations, application, and lifespan.

No. Flamex PF is formulated with clear, microscopic fire-suppression polymers that absorb into the internal cellulose fibers rather. Once dry, the fabric remains pliable, soft to the touch, and free of discoloration or chalky film.

Under normal indoor conditions (drapes, theater backdrops, wall tapestries), Flamex PF remains active and compliant for the life of the fabric, provided it is not subjected to wet laundering. If the fabric is washed in water, the treatment dissolves and must be reapplied. More than two dry cleaning methods may diminish retardancy, so, reapplication is recommended.

Yes. Flamex PF meets and exceeds the benchmark NFPA 701 Test Method, and California Title 19. We supply Flame Retardant Certificates upon request with your order to submit directly to your inspector.

Yes, a clean plastic compression pump sprayer with a fine mist nozzle works wonderfully. Keep the spray nozzle 12 to 18 inches away and sweep in overlapping passes for uniform coverage. For mass industrial runs, airless paint sprayers or immersion vats can also be utilized.
Flamex PF is a non-hazardous, water-based solution free of PBDEs, carcinogens, and petroleum distillates. While applying, ordinary safety precautions like eye protection are recommended, but it releases zero VOC fumes and is completely non-hazardous once dry.
