What Flame Stop does

Flame Stop, Inc. is a private specialty chemical manufacturer founded in 1990 and headquartered in Fort Worth, Texas, with an additional production facility in Honolulu, Hawaii serving export markets. The company manufactures intumescent fire retardant products that prevent flame spread through self-extinguishing chemical reactions, with proprietary formulations that penetrate and bond to the molecular structure of substrates such as wood, fabric, foam, and drywall. Its product portfolio includes Flame Stop I (universal fire retardant for interior surfaces), Flame Stop I-DS (for difficult-to-treat porous materials), Flame Stop II (interior/exterior wood treatment), Flame Stop III (paint additive for latex-based paints), Flame Stop IM (intumescent latex paint), and Flame Stop V (firestop caulk). The products are certified by multiple laboratories including UL, Intertek, and Southwest Research Institute, and meet FAA, ASTM, and NFPA standards.

The company's business model centers on one-time product sales through a dual-channel distribution approach: direct e-commerce via its website and a wholesale/master distributor network. Products are priced on a quote-based model ("Call for price") with no publicly disclosed pricing. The company serves a diverse B2B customer base across hospitality (hotels, restaurants, cruise ships), healthcare (assisted-living facilities), education (schools), entertainment (theaters, amusement parks, haunted houses), real estate (apartments, office buildings), and commercial construction. Same-day shipping is offered on most products, with free technical support provided to both direct customers and distributors. Flame Stop positions itself on cost-efficiency advantages including single-coat application (versus competitors' two to three coats) and low-pressure spray equipment requirements, claiming up to 50% labor cost savings for end users.

Core offering

Flame Stop manufactures fire retardant chemical products that prevent flames from spreading through intumescent self-extinguishing reactions. The product line includes fire retardant sprays for wood, fabric, and porous materials, intumescent latex paints, paint additives, and firestop caulks. Products bond to the molecular structure of substrates and are sold direct through e-commerce and via a wholesale distributor network for commercial and residential fire protection applications.

Product overview

Flame Stop Inc. manufactures a portfolio of fire retardant products that function as intumescent paint formulations preventing flames from spreading through self-extinguishing chemical reactions. The product line consists of five distinct offerings: Flame Stop I (fire retardant for fabric and interior cellulotic materials), Flame Stop I-DS (fire retardant for porous materials including foams, thatch, and difficult-to-treat surfaces), Flame Stop II (fire retardant for wood materials for interior/exterior use), Flame Stop III (paint additive for latex-based paints), and Flame Stop IM (interior intumescent latex paint for commercial surfaces). These products are primarily penetrants that bond with the molecular structure of substrates and typically require only single-coat application with low-pressure spraying equipment, distinguishing them from competitor products requiring multiple applications with high-pressure equipment. The company also offers Flame Stop V as an intumescent firestop caulk for through-wall and floor penetrations.

• International Fireproof Technology Inc. (IFTI): Specialty manufacturer of intumescent fire-retardant coatings (DC315, FireShell) targeting wood framing, EIFS, and commercial interiors. Directly comparable in intumescent paint technology, code-driven positioning, and channel model.
• Fire Retardant Coatings of Texas (FRCT): Regional manufacturer of post-treatment fire retardants for lumber and wood structures. Overlaps with Flame Stop II's exterior/structural wood focus and shares a Texas/Southern U.S. customer base.
• TPR2 Corporation / Therma-Guard: Producer of flame-retardant chemical treatments for wood, paper, and textiles. Directly comparable product line and chemistry to Flame Stop I/II.
• Contego International: Specialty intumescent thin-film paint manufacturer for steel and wood. Comparable in intumescent technology focus and code-driven fireproofing positioning, though more concentrated in structural steel applications.

Broad incumbents

• Nullifire (Tremco CPG): Established intumescent coatings brand under Tremco Construction Products Group, offering a broader portfolio across steel, timber, and concrete substrates. Comparable intumescent technology with deeper specification relationships and global distribution.
• Carboline: Major industrial coatings manufacturer with a dedicated fireproofing product line (Pyrocrete, Thermo-Sorb). Comparable end use (passive fire protection) but operates at much larger scale with broader substrate coverage including steel.
• PPG Industries: Global coatings giant whose protective and marine coatings segment includes fire-protection and intumescent products. Comparable chemistry and end markets, but addresses them as part of a much broader portfolio.
• Hempel A/S: Global coatings manufacturer with intumescent fire-protection offerings (Hempafire) for hydrocarbon and cellulosic fire scenarios. Comparable passive fire protection positioning with significantly larger scale and international footprint.
• 3M: Diversified industrial conglomerate offering fire-protection products across multiple categories, including firestop sealants and specialty coatings. Comparable only loosely; competes primarily through scale, distribution, and bundled safety solutions.
