Frequently Asked Questions

What kind of technical support can I get from Flame Stop®?
At Flame Stop®, we still believe in personally answering the phone. In fact, when you call our toll-free number, you’ll always speak directly to a live person who is knowledgeable about our products and processes. From our CEO and company president to our managers and employees, Flame Stop® personnel have all witnessed fire tests and understand building and NFPA codes and standards. We work with building officials and fire marshals nearly every day, answering questions and providing test reports.

Are there bromides or formaldehyde in any of Flame Stop®’s products?
No. Since their invention, Flame Stop® fire-retardant and firestop products have never been toxic. While formaldehyde might be considered non-toxic at very low levels, it remains a known carcinogen and we will not use it. At Flame Stop®, we believe fire and flame retardants that contain toxic chemicals give the industry a bad name.

Can one product fire retard all materials?
No. Different materials require different products. For example, would you apply a latex-based paint to fabric? Our expertise allows us to always recommend the right Flame Stop® product for your specific needs.

Can I fire retard the material myself or do I have to be a licensed applicator?
In some cases, you have to be licensed in the State of California and New York City. With most applications, however, you can fire retard the material yourself—as long as you closely follow the application instructions. Because Flame Stop® products are non-toxic and odorless, you can use a garden sprayer or an airless paint sprayer to apply our liquid fire retardants. Also, since most of our products are penetrants, you don’t have to check a mil thickness.

When it comes to fabric, the only way to truly know whether the Flame Stop® product was applied correctly is to perform the NFPA 705 field test after the application. This test utilizes a kitchen match, kitchen tongs, and a small swatch of the fabric, and accurately indicates sufficient saturation
