Wild Rust Activator (Refill)

What it is

Wild Rust is a brush-on decorative coating loaded with real metal particles — iron for the Corten steel look, copper for verdigris. The base alone dries matte dark grey; the transformation happens when you apply the Attivatore, a reactive solution that makes those metal particles genuinely oxidize, growing authentic rust or green-blue patina right on your wall. It is real chemistry, not printed texture, so every surface develops its own one-of-a-kind pattern.

Wild Rust Activator (Refill): Refill of the reactive solution that makes the oxidation happen; one bottle works with both Iron and Copper bases. Use it undiluted — each coat deepens the effect through a 4-to-6-hour reaction.

Why choose it

• Real oxidation, not a faux finish — the base contains actual iron or copper aggregates, so the rust and verdigris are genuine and no two surfaces come out identical.
• You control the depth: each Attivatore coat intensifies the effect through a 4-to-6-hour reaction, from a light blush of oxide to full Corten or verdigris, and the Protettivo sealer freezes it exactly where you stopped.
• The look of Corten steel or aged copper on surfaces where metal plate is impractical — one 2.5 L base covers roughly 160-215 sq ft (15-20 m2) in two coats, indoors or out once sealed.

How it’s applied

1. 01Start with a clean, sound surface primed with a smooth acrylic primer — not a gritty quartz primer.
2. 02Brush or roll on two coats of the metal-loaded base; it goes on matte dark grey, with no rust in sight yet.
3. 03Once the base is dry, apply the Attivatore with a brush, sponge, or spray — genuine oxidation develops over the next 4 to 6 hours.
4. 04Each additional activator coat deepens the effect, so stop whenever the patina looks right to you.
5. 05Let the effect mature for 24 to 48 hours, then seal with two coats of Protettivo — it goes on milky, dries clear, and stops the oxidation exactly where you left it.
