Description
High-quality phosphoric acid for converting surface rust to a paintable phosphate and removing mineral deposits from concrete, tiles, and metal. Gentler on many metals than hydrochloric acid, making it suitable for treated steel and galvanised surfaces when used as directed. Ideal for surface preparation before priming. Dilute per application, apply evenly, and rinse thoroughly. Avoid use on sensitive stones. Use PPE and follow safe handling guidelines. Store upright in a cool, ventilated location.
