F.W. Webb’s FireIce Shield is a nontoxic, eco-friendly, noncorrosive versatile gel. It helps prevent ignition from welding flames, sparks and other construction ignition sources that could otherwise lead to an accidental structure fire. It is highly effective, yet sprays on and cleans up easily with water, leaving no residue. The colorless, odorless gel blocks heat transfer and cools treated materials on contact for immediate handling. It protects virtually any material, including wood, sheetrock, cloth, wires, insulation, plastic, vinyl and metal, as well as painted and finished surfaces.
