A customer needed their steel digester tank lids and a steel stairway refurbished because they were in poor condition. We used a two part coating system comprised of a rust converter primer and a protective top coat specifically formulated for municipal wastewater environments. First, we prepared the surface to remove all dirt and loose scale. Then, we applied the primer and top coat. This coating system not only improved the overall appearance but also provides a non-slip surface for added safety.
