Most effective and tested fire-gel product on the market. 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. Barricade is now available to homeowners who can apply the water/gel coating on their own property in front of an approaching wildfire, before retreating to a safe area. When mixed with water at the end of a garden hose, super absorbent polymers in the gel concentrate trap water molecules and suspend them in millions of tiny "bubblets." Sprayed onto the flammable surfaces of roofs, windows, eaves and walls of a house, vehicles, or propane tanks, a "wet blanket" wrap of Barricade can be applied up to 24 hours before an approaching wildfire. Homeowners can evacuate safely, and firefighting resources can be focused on the wildfire rather than on the already protected structures. Barricade can be washed off with plain water after the fire danger has passed. This eductor nozzle fits a standard 3/4-inch garden hose and is to be used with the 1-gallon containers of Barricade Fire Gel. Barricade Fire Gel is a superabsorbent polymer fire retardant gel that has saved hundreds of homes during the California Wildfires. Barricade Fire Gel was the first liquid fire gel concentrate to be approved for use by the Forest Service that does not contain toxic chemical additives known as NPEs and petroleum distillate oils. Note: Other Long Term Fire Retardants like the infamous red colored retardant that's dropped from airplanes all over California contain phosphates, sulfate salts, and pesticides that have certain negative effects on the environment where they are dropped. Barricade is completely safe and can be used on houses, shake roofs, solar panels, decks, doors, windows, eaves, fences, outbuildings, sheds, dog houses, log piles, brush, shrubbery, trees, haystacks, cars, boats, grilles, LP and propane tanks. Barricade Fire Gel was discovered and then invented when it was observed that baby diapers did not burn in a dumpster fire. When you coat your house with Barricade Fire Gel, the gel will create a fire break or fire shield when combined with water. This is the secret recipe to ensure no embers ignite when a wildfire reaches your property. We are an authorized Barricade Fire Gel stocking dealer.
