- For which kind of boat is a hard antifouling suitable? -
Applying an underwater coating is recommended for boats with long lay times, trailer boats and sport boats with speeds of up to 70 knots. Hard antifouling should also be applied in waters where boats or yachts run dry. The surface does not polish or rub off.
These kinds of antifouling form a harder layer than other types.
Hard antifouling provides the hull with long lasting protection, despite long lay times without movement. The effect of the biocides only begins in the water, so the boat can easily stay in winter storage for days or weeks.
With hard antifouling, the surface dries out after application forming a hard, sandable covering. The binding agent, also called matrix, is insoluble in water. This layer usually contains the bioactive substances that will protect your hull from fouling. The effect of the biocides only begins in the water, which is why the boat can easily stay in winter storage for days or weeks.
The active ingredients are released from this matrix, leaving the empty binding agent residue at the end.
Experts recommend re-applying the antifouling coating once every year. However it is possible to apply several layers at once in order to make the boat endure several seasons. Before deciding for this solution though, please consider contacting us beforehand whether or not it is possible with your chosen product.
No antifouling coating can be universally applied to any underwater area. It depends, for example, on the conditions of the water, the boat, the speed and much more.
It is also necessary to know which underwater paint was used by the previous owner of a used boat. When taking over the boat, you should ask about the type of antifouling that was previously applied.
If you are unsure which is the right antifouling for your boat, please give us a call or ask at your home marina.
