Looking for a simple way to boost safety in your classroom, home office, or small business? Meet Flamex PF-1, your versatile solution for interior fire protection. While most people think about treating structural wood, it is just as critical to secure the everyday items that often fuel a blaze. That is why Flamex PF-1 shines as an effective , cardboard, and straw—materials that are frequently the first to ignite but are easily overlooked during safety inspections
Unlike heavy intumescent paints that can leave a thick, messier coating, Flamex PF-1 is a clear penetrant that absorbs directly into the substrate. This allows your projects, and displays to retain their natural appearance while gaining powerful protection. Modeled after top industry standards, this spray is designed to help surfaces achieve a Class A fire rating (ASTM E-84), the highest standard for reducing flame spread and smoke development in public buildings. It is important to remember that this is a fire retardant—chemically designed to slow the spread of flames only. It does not give fire protection rated in minutes or hours like a intumescent paint
Best of all, you don’t need to be a professional contractor to use it. The water-based, non-toxic formula is safe for indoor environments and incredibly easy to apply; simply spray the object until the the recommended application rate is applied and let it dry. Whether you are fireproofing paper projects for a school inspection or fireproofing wood at home, Flamex PF-1 offers professional-grade peace of mind at a budget-friendly price
Frequently Asked Questions:
Can I use Flamex PF-1 on curtains or other fabrics?
No. Flamex PF-1 is designed specifically for wood, paper, and straw. Fire retardants should always be formulated for particular substrates to ensure proper performance. Although some manufacturers market their products as universal solutions, fire retardants are not one-size-fits-all. Using a product on the wrong substrate can lead to reduced effectiveness, changes in the material’s appearance, or even complete failure during fire testing.
Is Flamex PF-1 toxic?
No. Unlike halogenated or melamine based products.
Does Flamex PF-1 affect the look of wood?
No. Flamex PF-1 is a colorless and odorless water-based spray that allows unfinished wood to maintain its original colors, appearance, and durability without leaving a visible residue.
How many coats are needed for a Class A finish on wood?
The application rate is approximately one ounce per square foot. How many coats to achieve this application depends on how porous the wood substrate is.
Pro Tip: Always refer to the specific manufacturer’s product data sheet and application instructions, as applying the required thickness or number of coats is critical for the product to successfully meet fire safety standards
