FAQ

Antifouling is a protective coating that prevents the growth of algae, barnacles, and other fouling on the underwater part of a vessel's hull. It works by creating a surface that is unfavorable for organism growth or by gradually eroding to remove fouling. Antifouling improves gliding, reduces fuel consumption, and extends the hull's lifespan.

Choosing an antifouling coating depends on the vessel type, sailing speed, hull material, and conditions of use. Self-polishing antifouling coatings are suitable for most recreational vessels, while hard antifouling systems are often used for fast vessels.

For the Adriatic Sea, self-polishing antifouling coatings are most commonly used, providing effective protection against algae, slime, and barnacles throughout the entire season.

The frequency of renewal depends on the type of coating, vessel type, and operating conditions: Self-polishing: once a year or every season, Hard: every 1–2 years, Environmentally friendly: according to the manufacturer's instructions or our experts.

The required amount depends on the vessel's length and the surface area below the waterline. On average, 1 liter of antifouling coating is enough for approximately 8–10 m² of surface.

The most suitable time is before the start of the boating season, or within the period specified by the manufacturer based on the planned launch date.

Yes, in most cases this is possible if the old coating adheres well and is compatible with the new system. Before application, it is advisable to check the manufacturer's instructions.

Old antifouling is removed by sanding, blasting, or special coating removers. The choice of method depends on the type of existing coating and the condition of the substrate.

For aluminum vessels, special copper-free antifouling coatings must be used, as conventional copper-based coatings can cause galvanic corrosion.

Self-polishing: wears away gradually, suitable for frequent sailing, continuous surface cleaning. Hard: resistant to long periods in water, better for vessels that sail less frequently. Environmentally friendly: less harmful to the marine ecosystem, yet still effective in preventing fouling accumulation.

Microorganisms, algae, and barnacles quickly attach to unprotected surfaces in the water. An antifouling coating prevents their attachment and growth.

If the surface is not thoroughly cleaned and sanded, the antifouling will not adhere properly, leading to coating peeling, uneven protection, and faster hull wear.

Removal of old paint and fouling, sanding and smoothing the hull, cleaning with special brushes and detergents, inspection for damage and cracks, application of primer or epoxy layer as needed.

Neglecting hard-to-reach areas of the hull, insufficient sanding, applying antifouling without proper cleaning.

Primer is a base coat that improves the adhesion of the antifouling coating and protects the hull from osmosis. It also ensures an even application and a longer lifespan for the protection.

Epoxy coating is used as protection against osmosis and mechanical damage to the hull. We recommend it for older vessels, vessels with damaged hulls, or for additional protection under self-polishing or hard antifouling.

Older boats, vessels with damaged or osmotic surfaces, vessels sailing in harsher conditions (saltwater, high temperature).

too few layers or uneven application, incorrect choice of coating type, insufficient sanding before application.

Osmosis is the penetration of water through the laminate, causing blistering, paint peeling, and long-term hull damage. Early signs include bubbles or discoloration of the coating.

To protect against osmosis, epoxy barrier coatings are used, such as Gelshield 200 and other epoxy systems for laminate protection.

diagnosis and hull inspection, removal of damaged layers, application of epoxy and protective layers, testing and advice for preventing recurrence.

Depends on the vessel size and hull condition; typically 1–3 days, including preparation, application, and drying.
