Application
Real Metal. Professional Application.
ATRIA Metallicum contains 50% real metal powder in a polyurethane gel base. Applied with a spatula in 1–2 coats, then polished after 12–18 hours with 1000-grit and 3000-grit pads to reveal the metallic lustre. Wild Rust finishes use a separate oxidation process with the Attivatore activator.
Professional application is recommended — the polishing technique requires experience to achieve an even, consistent metallic finish. For project guidance or applicator referrals, talk to our team.

Components
Need to extend a Wild Rust project?
Extra Wild Rust base, activator, and protective sealer for larger installations or active Wild Rust Iron and Copper projects. For new projects, the Complete Set above is still the safest starting point because the finish needs all three components to function.
