Fire Retardant Coating For Steel Mastic

Fire Retardant Steel Mastic is a high-performance, intumescent fire-protection coating designed to enhance the fire resistance of structural steel. When exposed to high temperatures, the coating expands to form a thick, insulating char layer that protects the steel from rapid heat transfer, helping maintain its structural integrity during a fire.

The mastic formulation is ideal for protecting steel columns, beams, and other structural members in commercial, industrial, and residential buildings. It offers excellent adhesion to properly prepared steel surfaces, is easy to apply by trowel or spray, and provides durable, long-lasting protection. The coating can be used in both interior and sheltered exterior environments when finished with a suitable topcoat.
