F2 ECO

F2 EcoHull is a fouling-release system, not a classic antifouling. Instead of killing fouling with biocides, the ultra-smooth surface prevents attachment physically. Three core advantages: biocide-, PFAS- and VOC-free, therefore usable without restriction in regulated waters. Service life of five years or more instead of annual repainting. And the smooth surface reduces hydrodynamic drag, which saves fuel and increases speed.

F2 EcoHull is suitable for motor boats, sailing boats, trailer boats and dinghies made of GRP (gelcoat), carbon, aluminium, steel, wood or PVC. It can be applied to the entire underwater area: hull, saildrive, rudder, through-hull fittings and trim tabs. For propellers and shafts, F2 OptiProp is the dedicated product. F2 performs best on regularly used boats, long lay-up periods can lead to light natural fouling.

You need one litre per component per 10 m² of hull area. For the standard build-up (Primer + Adhesive Coat + Top Coat) you need roughly three litres of material per 10 m² of hull area. The exact kit size for your boat is determined by our hull area calculator in a few clicks. It also factors in your sailing area and usage profile and gives you a tailored recommendation.

F2 EcoHull does not require a separate approval. The system works physically through its smooth surface and contains no biocides, no copper and no PFAS. As a result it does not fall under the EU Biocidal Products Regulation in the first place, making it suitable for Lake Constance, Swiss lakes and other biocide-restricted waters, in both freshwater and saltwater. Freshwater fouling such as algae and mussels finds little purchase on the smooth surface. Light fouling releases at speed or wipes off. With long lay-up periods or in high-pressure fouling areas, harder fouling can also develop, but it removes without residue.

When applied and maintained correctly, an F2 EcoHull coating lasts for 5 years or more, eliminating the need for annual repainting. F2 EcoHull works through physical rather than chemical action: its ultra-smooth surface prevents fouling and won't leach. With proper care, its performance remains intact even beyond this period. If you want to refresh the surface after 5 years, simply roll on a new layer of Top Coat. A complete coating overhaul is not required, and any damaged areas can easily be spot-repaired at any time.

F2 needs a smooth, hard, dry and structurally sound substrate. The general recommendation is to remove the old antifouling completely, down to the underlying barrier primer. This gives you the ideal base for an F2 coating. Only if your old antifouling is still in perfect condition (smooth, intact, firmly adhered) is thorough sanding with P180 to P220 sufficient.

No system guarantees 100% fouling-free hulls. F2 EcoHull prevents fouling from getting a foothold, the ultra-smooth, water-repellent surface offers nothing to grip on. How effectively F2 performs depends on how often the boat is used, the cruising speed and the area. Even at normal cruising speed light fouling releases, higher speeds from around 10 knots reinforce this effect. With long lay-up periods or in high-fouling areas, hard fouling can also develop, but it can always be wiped off without residue. One or several mid-season cleans are advisable depending on your usage profile.
