Fire Retardant Additives

Frequently Asked Questions About Fire Retardant Additives

What are fire-retardant additives for paint?

Fire retardant additives are specialized chemical compounds—available in both liquid and powder forms—designed to be mixed into standard paints, stains, or coatings. Products like our M-111PA or FS3 transform regular decorative finishes into fire-protective barriers without significantly altering the paint's color or texture.

How do fire-retardant additives work?

These additives work through a process called intumescence or chemical heat absorption. When exposed to extreme heat or an open flame, the additive reacts within the paint film, forming a protective char layer. This layer insulates the substrate (such as wood or drywall), deprives the fire of oxygen, and significantly slows the spread of flames.

Can a fire-retardant additive help paint achieve a Class A fire rating?

Yes. When mixed at the correct ratios and applied to a compliant substrate, many of our additives are designed to help your coating reach a Class A Fire Rating (the highest rating for flame spread index). This is a cost-effective way to meet strict building codes and fire safety requirements for commercial and residential interior finishes.

Are fire-retardant additives compatible with both water-based and oil-based coatings?

Compatibility depends on the specific additive. We offer specialized solutions for different carriers:

• Water-Based: Most of our additives are optimized for latex and acrylic paints.
• Oil/Solvent-Based: Products like DekGard are specifically formulated for oil-based stains and coatings. Always check the product specifications to ensure the additive matches your specific paint type for a seamless mix.

Where can fire-retardant paint additives be used?

These additives are ideal for any interior surface where fire safety is a priority or required by law. Common applications include:

• Wood Surfaces: Plywood, OSB, and decorative wood paneling.
• Wall Treatments: Drywall and gypsum board in hallways or stairwells.
• Textiles & Paper: Specialized additives can also be used for stage scenery and wallpaper.

How do I choose the right fire retardant additive for my project?

Choosing the right product depends on two main factors: your base coating (water vs. oil-based) and your target fire rating.

• For standard latex paint projects, M-111PA is our most popular versatile choice.
• For exterior wood or oil-based stains, look toward DekGard. If you are unsure which additive will meet your local fire marshal's requirements, please contact our technical team for a recommendation.
