Rust Grip® is a tough, one-part, moisture-cure polyurethane coating that absorbs atmospheric moisture to cure. Rust Grip® is loaded with a metallic pigment for strength and is also resistant to chemical solvents and acid splash. Upon curing, Rust Grip® provides a protective coating film of superior adhesion and flexibility, and is resistant to abrasion and impact. Rust Grip® can be used as a primer or as a one-coating system. It is patented to encapsulate lead-based paints and other toxic materials, including asbestos. Rust Grip® can be applied over pressure-washed, completely dry flash rust and firmly bonded commercial paints. In most cases, a white or near-white blasting is not required. A light to medium surface rust is preferred as the profile.
