QUESTIONS & ANSWERS

To repair corroded metal with the heat resistant epoxy, Belzona 1511 (Super HT-Metal), only apply the epoxy to clean, firm, dry, and well-roughened surfaces. To achieve this, firstly clear away any loose contamination and use Belzona 9111 (Cleaner/Degreaser) to clean and degrease the surface. Following this, roughen the surface by blast cleaning, deeply scoring, or grinding. Degrease the surface again, allowing the surface to dry before combining the reactive components. To do this, transfer the entire amount of Base and Solidifier components onto the Belzona Working Surface. Mix thoroughly to achieve a uniform material free of any streakiness. Next, apply the Belzona 1511 (Super HT-Metal) directly onto the prepared surface with the plastic applicator or spatula provided. Finally, mixing tools should be cleaned immediately after use with Belzona 9111 or any other effective solvent e.g., Methyl Ethyl Ketone (MEK). Application tools should be cleaned with Belzona 9121, MEK, or cellulose thinners.   For more information, read the Instructions for Use (IFU): Belzona 1511
