Thin Film Antifouling

Thin film antifouling

- When should I choose thin-film antifouling? -

Thin-film antifouling has a hard, very smooth, low-friction surface. A major feature of every thin-film antifouling is that it does not work by releasing active ingredients into the water, but by creating a very smooth surface, which makes it difficult for organisms to attach. Fouling is less likely to take place if the surface is not suitable to settle on from the start.
Furthermore, the smooth covering optimises boat speed, allows the boat to glide easier and faster through the water and reduces fuel consumption. The PTFE additive (Teflon) further strengthens the surface structure.
Ideally suited for regatta boats, speedy gliders, motor and sailing yachts that regularly sail on inshore waterways and rivers.
 

Pros and cons of thin-film antifouling

A great advantage of thin-film antifouling is that its use avoids the build-up of thick layers of paint that could flake or peel off after some time. In addition, it is very quick and easy to use and work with. Thin-film antifouling is also worth considering for environmental reasons, because it only contains a small amount of biocides.
One disadvantage is that only the same type of antifouling can be applied to this kind of protective coating. Due to its smooth surface, other types of antifouling will not adhere to it. The only way to change the type of antifouling is to remove all layers and apply a fresh coat to the hull.
 

Method of application

It is recommended to use short-haired rollers for applying antifouling paints. We advise having several of these at hand when possible, mainly because cheaper rollers tend to dissolve very quickly. Brushes are not suitable for underwater painting. Brush hairs can become stuck in the antifouling paint and cause the antifouling layer to become more permeable.
 

Choosing the right antifouling

When choosing the right type of antifouling for your hull, you should try to obtain the best possible information beforehand, e.g. from a seller or your home port. No antifouling coating is universally suitable for every surface. Due to their smooth surface, the thin-layer antifoulings are suitable for boats on the North Sea, Baltic Sea and inshore waters, to name but a few.
You should find out which underwater paint was used by the previous owner of a used boat. Make sure you find out which antifouling was used before taking ownership of any second-hand vessel.
In addition, legal regulations must be considered. The application and use of some types of antifouling is prohibited in some countries because antifouling products contain biocides.
