Hammerite RustCap allows contractors to paint over rust without priming. It can be painted directly over firm, rusty surfaces such as iron and steel, providing a deep, rich, decorative finish that is resistant to corrosion and the damaging effects of moisture and severe weather. As the rust-encapsulating coating dries, heat-hardened glass flakes interlock with special resins to form a surface of protective resin and glass particles. Moisture and dirt can’t penetrate it, so rust can’t get started or continue. Hammerite dries to the touch in 30-45 minutes. It is available in a broad range of traditional hammered finish colors and smooth finish tones. For more information, call 1-866-774-6371 or visit the Rust Cap Web site.
