Zero Rust® Primer – High-Performance Rust Inhibitor

Zero Rust® Primer – High-Performance Rust Inhibitor for Metal & Steel Surfaces

Zero Rust® Primer is a high-solids, phenolic-modified alkyd coating formulated to prevent rust and corrosion by forming a durable, oxygen-blocking barrier directly on steel surfaces. This primer delivers superior adhesion to both new and aged metal, cutting off oxygen to halt the rusting process at its source.

Free of lead and isocyanates, Zero Rust® Primer is safe and easy to apply, even over marginally prepared or partially rusted surfaces. It is a single-component, air-dry system that outperforms expectations—surpassing 2,000 hours in ASTM B117 salt spray testing for corrosion resistance.

Ideal for use on:

  • New and weathered steel

  • Rusty or partially rusted surfaces

  • Previously painted metal

  • Decorative fixtures, railings, barns, and metal furniture

Note: Not intended for use on surfaces that will be submerged in water.
