The Karnak 19 Ultra Rubberized Flashing Cement (Wet and Dry) is a next-generation elastomeric flashing cement, engineered with rubber-reinforced asphalt, mineral fibers, and refined solvents. Its heavy, pliable consistency makes application by trowel easy, while forming a durable elastomeric coating with excellent adhesion, superior strength, and high resistance to water and weathering.
Formulated with special chemical ingredients, 19 Ultra features a unique water-displacement capability. It dries to a tough, flexible, waterproof, and corrosion-resistant rubber coating, offering maximum protection and reliable performance across a wide range of temperatures and weather conditions. Available in 5 gallon, 3 gallon, 1 gallon, and 10.1 oz. sizes.
