PFB Marine Metal Primer
Anti-corrosion metal primer with zinc phosphate inhibitors. Bonds directly to bare steel and aluminum for maximum adhesion before topcoat application in marine environments.
PFB Marine Metal Primer is a zinc phosphate anti-corrosion primer engineered for bare steel, aluminum, and iron surfaces in marine environments. It bonds directly to properly prepared metal and creates a protective barrier that prevents rust and corrosion from forming under the topcoat. This is not a consumer rust-inhibiting primer — it uses industrial zinc phosphate chemistry trusted by shipyards and metal fabricators for decades. Essential for aluminum boat hulls, steel keels, metal hardware, and any metal surface that will be exposed to saltwater or marine atmospheres.
Surface Preparation
- Remove all rust, mill scale, and old paint down to clean bright metal
- Sand or grind with 60-80 grit to create a rough surface profile
- Wipe with a solvent-based metal prep to remove grinding dust and oils
- Apply primer within 4 hours of surface preparation to prevent flash rust
- For heavily rusted surfaces, consider PFB Rust Converter Primer first
