Blackened Rust for a Paint Free Finish on Cast Iron
Cast iron gets tougher by rusting, and a beautiful black iron patina can be created by converting rust to a durable black iron patina finish. Mature rust on cast iron is a protective coating and blackened rust forms an attractive, lifetime paint free finish on cast iron. Save the planet and skip the paint with cast iron from Richmond Iron and a blackened rust patina using Black Max from Rhomar Industries.
Blackened Rust for Interior Installations
Blackened rust is a durable patina finish for interior cast iron. Blackened iron emulates the natural black iron finish of wrought iron and hot forged metal and is a good choice for historic re-development projects.
Three Steps to Black Patina Finish with Black Max
Step 1
Force rust cast iron by exposure to water and weather. Requires 2 to 6 weeks to develop a good coating.
Step 2
Apply Black Max solution to rusted cast iron. Wire brushing rust and applying multiple wet coats darkens conversion.
Step 3
Black Max is a water based solution and dries to the touch in 30 to 60 minutes. Black Max is ready for service or traffic in as soon as dry.
