Rust Inhibiting Primer
Two-in-One Rust Converter and Primer for Metal Roofs
Rust Inhibiting Primer is a water-based, single-component acrylic emulsion that combines rust conversion and priming in one step. Designed to simplify prep for metal roof restorations, it passivates red rust and creates a corrosion-resistant surface—ready for topcoating once the primer turns black.
There's no need to rinse between steps or worry about pot life. This time-saving solution delivers outstanding adhesion, effective corrosion control, and seamless compatibility with NanoTech's Cool Roof and All Weather systems. Just clean, coat, and go.
