→ Why use antifouling for your boat?
Antifouling paint is one of the and is designed to prevent fouling on your hull. Fouling is the build-up of plant and animal micro-organisms on a boat's hull caused by water. But is antifouling essential? Some people wonder, particularly in view of the high cost of antifouling for boats .
Two problems arise with the appearance of fouling: the boat becomes heavier, resulting in reduced speed and higher fuel consumption. It is therefore necessary to combat these organisms by applying a boat antifouling composed of biocides designed to release toxins that reduce their development. Antifouling is also essential for the most effective boat maintenance.

Before applying antifouling to your boat, it's essential to prepare the hull thoroughly. Start with a thorough cleaning using a high-pressure cleaner to remove dirt. Next, scrape off clinging algae and shells with a spatula, then sand the surface with abrasive sponges to obtain a smooth hull.
-
This preparation facilitates paint adhesion and improves its effectiveness. Take this opportunity to identify any imperfections and fill them with epoxy putty. Once these corrections have been made, rinse thoroughly and allow the hull to dry thoroughly. Finally, line the area with masking tape at the waterline to prevent any spillage.
-
Once the hull is ready, apply a primer to ensure better adhesion of theantifouling and maximize its durability. Antifouling should be applied in a dry environment, at a moderate temperature, and ideally shortly before launching.
-
If conditions are cold, place the pot of antifouling in a water bath of lukewarm water to facilitate application. Mix the product thoroughly to homogenize the active agents, and if diluting, do not exceed 10% by volume. Apply theantifouling with a roller in criss-cross strokes, concentrating on the most exposed areas for optimum protection.
How much antifouling should I apply to my boat?
The amount of antifouling to apply will depend on the length of your boat.To save you the trouble of calculating antifouling quantities, remember that up to 15 metres for a speedboat, you'll need around 1 liter per metre.
For a sailboat up to 15 meters, subtract 3 from the number of meters to obtain the number of liters to use. So, for a 13-meter sailboat, you'll need around 10 L.
→ The different types of antifouling
There are several types ofboat antifouling adapted to different supports and uses:erodible antifouling, which wears progressively and is suitable for regular sailing,hard matrix antifouling, ideal for fast boats or those often taken out of the water. Defining what you do on the water will help you decide which antifouling to choose for your boat.
For a biocide-free version, choosing a allows you to limit your environmental impact.Antifouling for aluminum hulls is formulated without copper to prevent electrolytic corrosion.Antifouling for RIBs and inflatable boats is specially designed to adhere to flexible materials such as PVC and hypalon. Finally, antifoulings for boat appendages are applied to rudders, keels and propellers, which are often more exposed to marine soiling.
→ Protect your boat hull with an erodible antifouling
A or self-polishing, gradually dissolves over the course of the season, maintaining a smooth hull while eliminating algae and shellfish thanks to the constant renewal of its biocide-laden active surface.
Its main advantage is that it doesn't need to be removed before re-coating, although multiple coats are recommended for optimum protection. However, it is not suitable for boats exceeding 20 knots, docked year-round or exposed to strong marine currents.
In this category, Micron 350 International Antifouling is a benchmark, and you'll also find a range of colors, such as blue and red antifouling.
→ Hard matrix antifouling: resistance and longevity
A is insoluble, unlike the previous one.
Even if it is insoluble, a hard matrix antifouling will gradually lose its biocides, but will remain present on your hull throughout the season. It is recommended for fast, immobilized boats.
In this category, we suggest our Ultra 300 International Antifouling, which will do the job perfectly.
