Underwater hull

For your underwater hull, we recommend removing the old antifouling coats; at least the loose components. If sandblasting is not available, we recommend using a coarse-grained, domed metal abrasive disc ('claw' disc) for this. However, avoid using it with a speed too high.

Ideally, after removing and cleaning the underwater hull with a high-pressure cleaner, leave it for some time so that any moisture that escapes due to osmosis can dry completely. Depending on the condition of your underwater hull, this process can take several weeks (e.g. winter).

It is then advisable to apply several layers of RIMA epoxy resin:

...

1. Pure epoxy resin (without additives) as primer/first coat (roller)

2. Filling with talc resin to remove unevenness. 

3. Then sand the underwater hull smooth with ordinary sanding discs.

4. Repairs are made with glass or copper epoxy resin (e.g. shaft suspension, fractures in the keel, etc.).

5. Finally, the entire underwater hull is filled or painted 1-2 times with RIMA copper epoxy resin.
