The world's longest lasting and most effective protective coating for Corten and Weathering Steel.


CT-7571-W is the worlds longest lasting and most effective coating that protects Corten Weathering steel from continuing to corrode and weather. The coating protects steel from UV, oxidation, bleaches and acids to ensure the desired patina remains perfect for the lifetime of the coating.

The new water-based product for 2022, CT-7571-W offers unparalleled protection and sealing properties with the addition of alcohol protection. The new water-based formula has a lower odour compared to the old product and is ideal for use inside and in confined spaces.

As world leaders in the process of aging and sealing of weathering steel, BROMOCO understand that in a world that needs to reduce its environmental impact and adopt sustainable manufacturing practises water-based products are becoming the new standard. We will be fully water based for 2023.

Note: Our old version solvent based CT-7571-T is currently being phased out and is only supplied if required. Please click [Contact Us] for more information.
