*Case of four 1-gallon containers* to be used with our home fire protection systems (see other listings) The Barricade II Fire Gel is an advanced fire-blocking solution designed to provide superior protection against wildfires. This pack includes four 1-gallon containers, making it ideal for homeowners, firefighters, and anyone living in wildfire-prone areas. The gel is approved by the U.S. Forest Service for both ground and aerial applications, ensuring its reliability and effectiveness. Most effective and tested superabsorbent polymer fire retardant gel product on the market that has prevented many homes from burning down in wildfires throughout the years. Four gallons will provide approximately 2,000 square feet of coverage at the minimum thickness required for protection. The gel will remain viable for 6 to 36 hours depending on weather conditions. High temperatures, very low humidity, and high winds decrease how long the gel will last. However, once the gel has been applied it can be re-hydrated and maintained by gently misting with water until you evacuate. You can also prolong the life of the gel by applying a thicker coat. For maximum protection, a 1/4 inch thickness is recommended, which will require purchasing additional gel. It forms a unique thermal protective gel-coating that stops fires from burning homes, structures, vehicles, fuel tanks, and other flammable objects. Barricade Fire Gel protects against radiant heat, direct flames, flying brands and burning embers. It is specially formulated to adhere to all exposed surfaces, including walls, overhangs, wood shake roofs, metal or fiberglass surfaces and glass windows. When mixed with water from one of our swimming pool wildfire protection system, it can be applied on grass, trees, and shrubbery to create a firebreak. Barricade Fire Gel was discovered and then invented when it was observed that baby diapers did not burn in a dumpster fire.
