Hammerite Rust Cap Paint

Hammerite Rust Cap paint is a long-lasting quick dry enamel that allows you to paint over rust with no primer needed. Its rust encapsulating formula and rust-preventive coating are designed to provide long-lasting metal protection to both interior and exterior applications. It also provides a decorative finish that resists corrosion and the weather. Use this product in a variety of applications, including covering rust and painting lawn furniture, crafts, machinery, and metal wagons. Also ideal for iron, steel and most other metal surfaces.

  • Glassguard Protection
    As the Hammerite coating dries, millions of heat-hardened glass flakes interlock with special resins, forming a super-tough barrier that seals out moisture to prevent rusting.
  • Paint Right Over Rust
    This long-lasting coating is designed to be applied directly over firm, rusty surfaces. The unique paint-right-over-the-rust capability allows you to achieve a smooth, deep finish, rich in color.
