The F2 antifouling revolution:
-
The problem
Underwater fouling is a constant nuisance for boat owners. It increases drag, drives up fuel costs, and leads to expensive maintenance. Traditional antifouling solutions rely on harmful biocides, silicones, and chemicals that not only harm you but also the oceans.
-
The solution
F2 is the revolutionary solution to underwater fouling: 100% eco-friendly, incredibly durable, and easy to apply. The hybrid polymer coating prevents organisms from attaching by making the surface appear like water to them – a single application protects your boat for at least 5 years.
✅ 100% free of biocides, toxins, silicones & VOC
✅ 5+ years of protection – with just one application!
✅ Smooth hull – improved performance.

Effective anti-fouling in just 3 simple steps:
-
1st layer: Primer
The primer seals the existing surface and protects against moisture and corrosion.
-
2nd layer: Adhesive Coat
The Adhesive Coat bonds the primer and top coat, ensuring strong adhesion.
-
3rd layer: Top Coat
The Top Coat creates the outer protective layer, preventing anything from adhering to the surface.
* The top coat is available in different colors.

⭐⭐⭐⭐⭐
From the very beginning, I was honestly impressed by its effectiveness against fouling. There was some slime buildup, but it could be brushed off from the dock in seconds, leaving the propellers looking brand new.

⭐⭐⭐⭐⭐
I have to admit, I was amazed: The boat sat at its mooring for six months, and I found only a very thin layer of slime and a few small crustaceans on the F2 ECO surface. Using clean, soapy water and a soft brush, I removed the slime and crustaceans in about 10 minutes – a fantastic result with minimal effort!

⭐⭐⭐⭐⭐
Our observations showed that any fouling that formed during the curing period was extremely easy to remove. Over time, the performance of the coating improved significantly. After approximately six months in the water, the coated surfaces were completely free of fouling.

Frequently Asked Questions
What exactly is F2?
F2 is an eco-friendly hybrid polymer coating that effectively protects your boat from underwater fouling for many years by creating an ultra-smooth, hydrophobic surface that prevents anything from adhering underwater. Best of all, F2 is 100% pollutant-free and environmentally friendly – for clean hulls and cleaner oceans!
Is F2 really environmentally friendly?
Yes, F2 is 100% eco-friendly as it contains no pollutants, biocides, solvents, catalysts, or VOCs. It has been independently tested and meets the highest environmental standards by protecting marine ecosystems and releasing no harmful substances into the water. With F2, you actively contribute to cleaner oceans and a sustainable future – without compromising on performance.
How long does an F2 coating last?
An F2 coating is exceptionally durable and designed to neither wear off nor dissolve. F2 comes with a 5-year warranty, but in practice, it lasts significantly longer. A single application provides lasting performance and saves costs on repairs and maintenance over time. After 5 years, the protection can be easily refreshed.
Can F2 be applied to any material?
Yes, F2 can be applied to nearly all underwater materials, including fiberglass (GRP), aluminum, steel, carbon, and even wood. It can also be applied over your existing antifouling, provided the surface is intact.
For optimal adhesion, we recommend carefully preparing the surface. You can find the specific requirements in our detailed application instructions.
How is F2 applied? Do I need professional help?
Applying F2 is incredibly straightforward and can be done without specialized knowledge or professional help.
Before applying, the surface should be smoothed with 120-220 grit sandpaper. In most cases, the old antifouling does not need to be removed (if you're unsure, feel free to contact us!).
The process involves three simple steps:
- Apply 1 layer of F2 Primer to prepare and seal the surface.
- Apply 1 layer of F2 Adhesive Coat to ensure strong adhesion.
- Finish with 1 layer of F2 Top Coat to create the protective hydrophobic surface.
Make sure to follow the drying intervals between each layer. All detailed instructions can be found in the product datasheet.
After just 36 hours, your boat will be ready to return to the water!
What color is F2?
The F2 Top Coat is available in various colors, including a glossy black (Glossy Black), a shimmering dark grey (Sparkly Graphite), and a shimmering blue (Sparkly Blue).
