🔌 Function

Zinc-phosphate primer promotes adhesion between bare metal and the colour topcoat while slowing under-film corrosion.

Common situations requiring primer

• Paint chips expose bare aluminium
• Gearcase skeg has been repaired
• Corrosion has lifted the original coating
• Midsection or bracket has been sanded
• Welding or grinding has removed the factory finish
• Surface has been prepared for a complete repaint

Application considerations

• Wash away salt and contamination
• Degrease the repair area
• Sand or mechanically remove loose oxidation
• Feather the edge of the existing paint
• Mask seals, anodes, shafts and machined surfaces
• Apply several light coats rather than one heavy coat
• Observe the flash and recoat times printed on the can
• Apply a compatible BRP or marine-engine topcoat
• Do not paint sacrificial anodes or grounding contact points
• Use appropriate gloves, eye protection and respiratory protection
• Apply only in a well-ventilated area away from ignition sources
