Antifoul Paint

We sell Antifoul paint with the highest levels of solids compared to others. So if you want the best protection check out our Norglass and Hempel pages. Hempel antifoul can go up to 36months before recoating, we recommend 3 coats.General life is 12-24 months. They have from 51% solids up to 58 % solids compared to other leading brands in the high to mid 40 %. So you get what you pay for. After 99 years of painting boats from 60 ft professional fishing to 10 ft row boats we know what is best. Active consituents of all anti-foulings must, by law be stated on the main panel of the label. Comparing the price and the stated grams per litre (g/l) can influence the choice of product.

Aluminum Hulls and Underwater Metals

Aluminum hulls, outdrives and props require paints that do not contain cuprous oxide, which reacts destructively with the aluminum. Copper-based paints are safe for use on properly primed stainless and bronze. Zinc anodes should be left unpainted to retain their effectiveness. Use Hempel Mille Dynamic after 3-4 coats of light primer. Mille can be used on all surfaces.

Overcoating information

On the whole most antifoulings are compatible and can easily be overcoated, however, some basic rules should be applied:

  • The condition of the surface to be painted must be good – ie free from contaminates and in a sound condition.
  • hard/non-polishing antifouling will leave an exhausted layer of resin at the end of the season. Before applying a new coat, it should be wet abraded to maximise the performance of the antifouling.
  • Teflon antifouling CAN be overcoated assuming it is in good condition and has been washed – DO NOT abrade before applying new antifouling.
  • A traditional/soft antifouling should be sealed with Underwater Primerbefore applying an erodible or hard antifouling on top of it.


  • If you are changing your antifouling, check application instructions of new product onto existing product. If in doubt, apply a tiecoat of Underwater Primer.
  • Keep the antifouling paint indoors before painting your boat as antifouling is easier to apply at “room” temperature.
  • Always give antifoulings a good stir before applying as they contain heavy pigments which can settle.
  • Apply an extra coat of antifouling along the waterline and the leading edges where more aggressive water flow takes place.
  • It is not advisable to thin antifoulings, however, in particularly cold conditions thinning the antifouling by up to 10% will help with application.
  • Never dry sand old antifouling as the dust is toxic.
