  • Preparation is extremely important
  • Antifoulings change colour after immersion, generally turning a little lighter after 2 weeks as the copper activates and begins to oxidise.
  • DO NOT use copper based antifoulings on aluminium or galvanised metals.
  • Iron keels should be ground and brushed until bright, any rust should be treated with Omnicote and then primed with Flag Multi Purpose Metallic Primer.
