Please Note:

  • 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.

For more information please see the product information sheet and MSDS. All orders are sent out with a detailed product information sheet.
