Notes

Antifouling
Depending on requirements, your underwater hull can/should be cleaned once a year manually or with a high-pressure cleaner. An antifouling coating, on the other hand, is NO LONGER NECESSARY, even in the following years. This also, from an economic point of view, means a remarkable savings potential, too. 

Biozidal effect
The copper bound in the epoxy resin has a natural biocidal effect on all invading organisms. This means that no toxic material is released into the water (as is usually the case with conventional antifouling paints, for example), but the copper remains permanently bound in the synthetic resin - similar to so-called antibacterial tiles. After curing, the synthetic resin itself is considered 'food safe', i.e. harmless to the environment and the user.

Consumption quantities
Regarding consumption, 1L of liquid epoxy should be planned for approx. 2 QM of multi-layer application (or boat length x 1.5 = approx. 15L of resin for a 10m long boat). Additional material should be planned for repairs. The use of other resins or epoxy resin without hardener is not advisable (does not harden).

...

Chlorine
The use of chlorine to clean the underwater hull should be avoided, as copper reacts chemically with chlorine to form copper chloride. Although this is only the case superficially and does not affect the stability, it however does lead to a yellowish discoloration.

Seawater
Finally, it should be noted that the RIMA epoxy resin has been specially developed respectively tested for maritime use ('German Lloyd'). It is therefore the perfect, durable solution for your underwater ship.
