Usage Directions

Always test a small area on the surface intended to be treated. Use an all-plastic pump-up sprayer to apply Raptor Rust Buster. For difficult-to-remove rust stains, apply the product at full strength to the surface to be treated. Work in 3 ft. by 5 ft. sections to completely cover the surface, and use a plastic bristle brush or broom to work Raptor Rust Buster into cracks and other crevices. After the application, allow a minimum of 10 minutes of contact for the chemistry to work. Tough or extremely old and set stains may take up to 30 minutes. Use a high-pressure sprayer to remove the treatment, rust, mud, and most stains from concrete.
