Wild Rust Protective Sealer (Refill)

Protective topcoat for Wild Rust finishes — for re-application, additional coverage, or larger projects

Refill

High-performance transparent water-based polyurethane protector for Wild Rust finishes. Creates a waterproof barrier that blocks further oxidation and locks in the decorative patina permanently. Apply in two thin coats after the oxidized effect has fully matured (24–48 hours). Essential for both interior and exterior Wild Rust installations. Does not alter the aesthetic character of the surface.

Refill SKU — for use with the Wild Rust Iron Set or the Wild Rust Copper Set. Wild Rust requires all three components (base + activator + sealer) to function — buy a Complete Set for new projects.
