Factors that should be considered when buying antifouling paint for your yacht:
- The condition and type of existing coats of paint
It is very important to know or find out which type of antifouling has been applied last. If it is still in good condition, it might be sufficient to carry out some boat maintenance and sand the surface a little, then apply new coats in order to renew the anti-fouling capabilities. SVB offers a wide range of antifouling paints from renowned manufacturers, such as International
, with the best value for money.
- Which underwater area should be protected?
No antifouling coating can be universally applied to any underwater area. In addition to hull antifouling, there is also antifouling specifically for metallic propellers and Z-drives.
This area requires a special antifouling coating, which is usually supplied in spray bottles. Similarly, not every antifouling is suitable for aluminium or steel. When buying anti-fouling, you should make sure that it matches the material of your boat. The fairway and the type of sports boat (sailboat, motorboat or trailer boat) also play a role when it comes to choosing the right antifouling.
- Self-polishing antifouling, hard antifouling or thin-film antifouling?
Which antifouling should be chosen depends on what was applied previously. Self-polishing
versions are mostly used on slower boats and sailing boats, while hard antifouling
is perfect for fast boats and motor yachts. Thin-film antifouling
does not work by delivering active ingredients to the water, but by creating a very smooth surface, which makes it difficult for organisms to attach.
- The water and conditions in which you navigate
The choice of antifouling also depends on the water temperature. Whether in the North Sea, Baltic Sea, Mediterranean, inland waters or Lake Constance - depending on where you navigate, other pollutants could find their way to your hull. Waters with a high water temperature, greater levels of pollution and low water exchange or current lead to increased fouling of the hull and more marine organisms.
- The quality and environmental compatibility of the antifouling
The effectiveness of underwater paints depends on whether they have been chosen correctly and, of course, on the bioactive ingredients. Unfortunately, not all antifouling paints on the market are environmentally friendly. Versions such as Hempel's Silic One
, for example, are referred to as biocide-free
antifoulings and have low VOC values (Volatile Organic Compounds). These antifouling systems are also good for the environment - or at least friendlier.
