Porter’s Instant Rust is an ageing/rusting solution for use over Porter's Liquid Iron. A chemical reaction between the Liquid Iron coating and the Instant Rust solution creates rusting and patination to give a weather beaten, rusted finish.

Water
Application Tools
Brush
Porter’s Liquid Iron and Instant Rust will continue to rust after initial application. On exterior surfaces be mindful that rust stains (caused by run-off) may appear on adjacent surfaces. To prevent these stains we recommend finishing with Porter’s Instant Rust Clear Sealer.
Liquid Iron treated with Instant Rust is a chemical reaction. Individual results may vary due to film thickness, methods used, time elapsed, ambient temperatures, substrate etc.
Do not apply in high humidity, below 10°c or above 30°c.
As soon as the second coat of Porter’s Liquid Iron is touch dry, (and can even be slightly tacky, but not wet), Porter’s Instant Rust solution can be applied.
Caution: Instant Rust contains hydrochloric acid, so please always wear rubber gloves and safety goggles (refer to SDS prior to use). Apply two coats of Porter's Instant Rust by brush. Allow minimum 3 hours dry time between coats. Rusted appearance will begin to develop within hours and will continue to increase over the next 12 hours. To increase intensity of rusted effect, up to three coats may be applied.
Tip: To accelerate the rusting effect surface can be lightly sprayed with water using a spray bottle.
Please Note: Liquid Iron treated with Instant Rust is a chemical reaction. Individual results may vary due to film thickness, methods used, time elapsed, ambient temperatures, substrate etc.
Complementary products:
We recommend finishing with Porter’s Instant Rust Clear Sealer (coverage 15m² per litre) on interior or exterior surfaces finished with Porter’s Liquid Iron & Instant Rust that require protection, sealing or isolation. Does not affect the finish, though no further oxidisation with occur after application. Allow Liquid Iron and Instant Rust to dry for min 48 hours prior to application of Instant Rust Clear Sealer.
