A 2-part epoxy can be used for various applications. Belzona epoxy materials can be used to repair and resurface metal, rubber, and concrete substrates.

To apply the repair composite, Belzona 4301 (Magma CR1 Hi-Build), the surface must be clean, firm, and dry. In addition, it must be free of rust, paint, and other surface coatings and contaminants. Condition the area using Belzona 4911 (Magma TX Conditioner). To mix the Belzona 4301 (Magma CR1 Hi-Build), transfer the entire contents of the Base and Solidifier tins onto a Belzona Working Surface.
