Why Apply Antifouling To Your Boat

Sailing

Many people enjoy the tranquillity and relaxation that boating offers, however there are several housekeeping duty’s that are not the most tranquil. Painting your boat with antifoul is never enjoyable, especially when the cold weather is setting in.

Antifouling paint is a major part of any Hull and it will protect the hull and other important parts below sea level.

Most people dream of owning a boat, but very few understand what is involved to maintain that fresh painted look. In harbours and estuaries the water contains immense numbers of microscopic organisms and plants collectively known as plankton, if given an opportunity they will settle on the Hull and grow.

If plankton is able to grow on the Hull, it may cause drag, stability issues for the boat owner and worst of all the increased fuel consumption, Antifoul paints are a great way to ensure that this doesn’t happen and that you are protected. Wooden boats are usually hardest hit but other boats need protection as well.

Effective antifouling paint is required if you want to ensure that your boat is safe from barnacle build up. All sorts of horrible things live in the sea and may seem harmless to us but to boats and other sea born machinery, it can cause a lot of problems.

Boats that haven’t been treated with antifoul paints can actually be slower, less responsive and far less fuel efficient which will cost you money.

What types of antifouling paints are there?

1 – Tropical Killa

An economical antifouling offering good performance and protection. Provides a scrubbable surface for seasonal protection.

2 – Protector

A cruiser grade antifouling offering competitive performance, compatibility with other paints are good.

3 – Antifouling D Type

A physically ablative antifouling offering excellent performance and protection. This has a softer film than Tropical Killa but offers superior performance. Contains a mixture of material which forms a complex matrix that wears away at a controlled speed.

4 – Antifouling A Type

Like ‘D’ Type, this is a physically ablative antifouling offering excellent performance and protection with the added benefit of being suitable for direct application to aluminium.

5 – Boot topping

An interface coating for use between the waterline and the deck coatings, providing a hard surface less receptive to marine growth and polish-able to remove grime.

In an ideal world all old antifouling should be removed back to a firm substrate. This is not always practical and more often than not the selected antifouling will be applied directly over many types of products with no problems experienced.

It should be noted that, due to the variety of products now on the market, an application of the new antifouling to a small area first is the only way to test to ensure compatibility. Leave the “Test Area” overnight and examine it carefully the next day. With any sign of reaction (i.e. blistering, splintering or flaking, colour inconsistency etc.) the barrier coat must be applied or all the old antifouling be removed.
