FAQ’S

Q: What is the difference between interior and exterior fire retardant ?

• Interior sprays are typically water-based, odorless, and low-VOC, optimized for fabrics, curtains, and raw wood inside the home.
• Exterior sprays are formulated with specialized polymers that resist “leaching” or washing away when exposed to rain, snow, and UV sunlight, ensuring long-term protection for decks, fences, and thatch.

Q: Can I use an interior fire retardant on my outdoor deck?

No, we do not recommend using interior-grade sprays for outdoor projects. Interior formulas are water-soluble and will wash off the first time it rains. For outdoor wood, siding, or landscaping, you must use a dedicated Exterior Fire Retardant that is specifically rated for weather exposure.

Do your fire retardant products meet commercial fire codes?

Yes, high-quality fire retardant penetrants and additives are rigorously tested to meet stringent industry standards, such as ASTM E84 (Standard Test Method for Surface Burning Characteristics of Building Materials) and NFPA 701 (Standard Methods of Fire Tests for Flame Propagation of Textiles).

Always check the specific product specifications on our category pages to ensure it meets the exact class rating (e.g., Class A or Class 1) required by your local fire marshal or building inspector.

Can I apply fire retardant myself, or do I need a professional?

Most of our fire retardants are designed for easy, DIY-friendly application. They can be applied using a standard garden pump sprayer, an airless paint sprayer, or even a brush or roller for smaller surface areas. Certificates are issued by us upon request after placing an order

However, for large commercial projects or public venues requiring official certification, you may need a licensed applicator to provide a certificate of flame resistance for code compliance.

How do clear fire retardants balance safety with visual aesthetics?

Our clear fire retardants balance safety and aesthetics by providing a layer of protection that slows the spread of fire without altering the natural look or finish of the material.
