MASK® FL is a broadly used polyurea spray elastomer system. It consists of the two components MASK® AMINE FL and MASK® ISO FL. By replacing standard formulations by MASK® FL durable surfaces with strong physical properties can be achieved. The FL series is a pure polyurea designed for flooring, and mechanically impacted surfaces with medium to high traffic. It offers long-term durability and flexibility and combines strong mechanical resistance with excellent crack bridging and waterproofing properties.
