Wild Rust Activator (Refill)

Reactive activator for re-application or larger projects — for use with Wild Rust Iron or Copper Sets

Refill

Reactive ammonia solution that activates and intensifies the controlled oxidation of Wild Rust coatings. Apply on completely dry Wild Rust surface with spalter brush, sponge, or low-pressure spray. Each additional coat deepens the rust (Iron) or verdigris (Copper) effect — giving full creative control over the final aesthetic. Do not dilute.

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.
