Flamex PF-1 Fire Retardant Spray for Paper & Displays

Ensure your commercial exhibits, retail installations, and creative projects are fully safe and code-compliant with Flamex PF-1 paper fire retardant spray. Lightweight cellulose materials like paperboard and corrugated cardboard are incredibly vulnerable to stray sparks and open flames. Flamex PF-1 provides a specialized, penetrative protective barrier that cools the substrate upon contact with heat, drastically reducing flame spread and smoke development to secure a Class A or B rating depending on coverage.

The premier advantage of Flamex PF-1 is its fast-drying, anti-moisture chemistry. Traditional liquid fireproofing agents warp, wrinkle, or ruin thin cellulose materials. Flamex PF-1 is engineered as a highly effective, non warping flame retardant for crafts and temporary displays, leaving your structures perfectly flat, rigid, and vibrant. Tested to compliant standards including ASTM E-84 and UL 723, this eco-friendly solution gives decorators and tradeshow exhibitors the power to satisfy strict fire marshal protocols without sacrificing aesthetic quality.

Key Features & Specifications:

  • Class A Performance: Capable of achieving elite Class A fire safety metrics under ASTM E-84, NFPA 255, and UL 723 testing.

  • Anti-Warping Technology: Specially optimized fire retardant spray for paper and cardboard that prevents bubbling or structural bending.

  • Multi-Surface Indoor Utility: The perfect trade show display fire retardant for booths, backdrops, papier-mâché, posters, and wallpaper.

  • User-Friendly Application: Odorless, non-hazardous, clear-drying formula that allows surfaces to be painted with latex coatings once cured.

  • Note: Looking to secure interior fabrics, drapes, or clothing? Check out Flamex PF. For high-humidity indoor zones or outdoor timber, transition to Flamex PF-2.

Flamex PF-1 is a fire retardant treatment designed for use on certain interior porous and absorbent materials, including paper, wood, and straw.

Flamex PF-1 is intended primarily for interior applications. For exterior wood applications, a product specifically designed for outdoor exposure like Flamex PF-2 should be used.

Flamex PF-1 treats combustible materials to help reduce their tendency to ignite and spread flame when applied according to the manufacturer’s instructions. Flamex PF-1 has been lab tested for a Class A fire rating on wood.

Depending on the project, Flamex PF-1 may be applied by spraying or another approved application method. The material should receive an even treatment according to the product application instructions.

Because results can vary by substrate, porosity, color, and application rate, a small test area should be treated before applying Flamex PF-1 to the entire surface.

Fire retardant treatments generally need to penetrate the material to perform as intended. Painted, sealed, coated, or otherwise non-porous surfaces may prevent proper absorption. Confirm substrate compatibility before use.

The required quantity depends on the type of material, its absorbency, the surface area being treated, and the required application rate. For Class A fire rating on 1/2″ or thicker wood, apply at 125 sq. ft per gallon. Measure your project area and consult the current product instructions when determining quantity.

Yes. Testing a small, inconspicuous area is recommended to confirm compatibility, absorption, appearance, and the desired finished result.

Code requirements vary by jurisdiction, occupancy, substrate, and application. Buyers should verify the applicable testing, documentation, application requirements, and local code acceptance for their specific project.
