Yes — RustSeal can be applied over another coating. Before you do, make sure the existing coating is fully cured. If the surface is glossy, lightly scuff it with 320 grit sandpaper and clean it thoroughly with KBS Klean. This proper preparation ensures long-lasting adhesion. If any sections of the old coating are loose or poorly adhered, use a wire wheel to remove them before prepping the surface.
Tip: The Foundation Matters Like building a house, the foundation of your paint project is critically important. RustSeal provides the strongest, most durable rust prevention foundation when applied directly to a properly prepped bare metal surface. When another coating sits between RustSeal and the metal, you are relying on that coating as your foundation — so its adhesion is everything. That said, applying RustSeal over a well-adhered existing coating is always a great option when bare metal application is not possible or practical. |
