Any boat left in water longer than a fortnight needs to be treated with antifouling paints.

The growth of algae and fouling organisms causes increased fuel consumption, performance reduction and, on a longterm basis, phenomena of osmosis with consequent possible damage to the grp hull.

Antifouling paints release biocides that prevent organisms from sticking to the hull and proliferate. As biocides are released immediately after paint application, it is a good practice not to apply the antifouling paint too early, and in any case not earlier than a month before boat launching.

Both self-polishingand hard-matrix antifouling paints are available on the market.

  • Self-polishingantifouling paints are gradually subject to wear over time and therefore help maintain the hull clean. They are meant to last all season if applied on sailboats and not too fast boats (up to 25 knots).
  • Hard-matrix antifouling paints will not wear out through use and therefore their function is essentially chemical. Suitable for fast boats (over 25 knots) and long cruises.

Osculati antifouling paints do not contain copper and therefore are fit for any kind of hull (fiberglass, aluminium, wood, etc.).

Here below detailed information about the different products are schematically shown to help you choose the one most suitable for your boat:

SELF-POLISHING antifouling paint:
• smooth surface and good film solubility
• for sailing or motor boats whose speed is < 25 knots

HARD-MATRIX antifouling paint:
• good abrasion resistance
• for boats whose speed is > 25 knots

Note: Prior to the antifouling paint always apply 2 coats of Primer Sealer 65.620.10/20

How much antifouling paint do I need?

Approximate liters of 2 coats of antifouling paint
