Directions for use
FOR RUSTED SURFACES (To Remove Rust) 1. Remove any oil, grease, & dirt from surface. Remove loose rust with a wire brush. 2. Apply product to affected metal full strength with a paintbrush, spray bottle or pump-up sprayer. Rinse applicator with water after use. Work the solution into rusted areas and allow product to dry overnight to fully neutralize rust. 3. Rinse or wipe surface with a damp cloth to remove any rust residue. 4. Paint treated surface within 48 hours of application to prevent formation of new rust. Two applications may be necessary to treat severe rust. FOR TREATING METAL FOR PAINTING (Phosphotizing) 1. Remove any oil, grease, & dirt from surface. 2. Dilute 1 part product with 3 parts water in a plastic container. 3. Apply product with a paintbrush, spray bottle or pump-up sprayer to metal. 4. Thoroughly rinse with water after 15-30 minutes. 5. Paint treated surface within 48 hours of application to prevent formation of new rust. FOR ETCHING CONCRETE (Before Applying a Coating) 1. Concrete must be clean and bare of sealers or coatings. 2. Dilute 1 part product into 4 parts water in a plastic container. 3. Apply this dilution evenly, at a rate of 300 sq ft./gallon, using a plastic garden watering can with sprinkling head. Do not pour onto one spot and brush out over surface. Product should begin foaming as it reacts with concrete - if no foaming happens concrete is sealed and sealer must be removed. 4. Let stand at least 10 minutes and then thoroughly rinse with plenty of clean water, scrubbing lightly with a nylon broom to remove any residue. Allow surface to dry before top coating.
