Antiosmotic HS Epoxy Primer 3:2

This particular product is recommended for protecting the laminate below the waterline, especially for repairing laminate affected by osmosis. Epoxy HS primer is a thick-layer epoxy primer designed to repair hull bottom damage.

The product is non-solvent-based, which means it does not contain solvents that could react with substances present in laminate damaged by osmosis, for example. Osmosis repair is a specific process that requires not only the right primer but also proper preparation and repair conditions. The product cures in 24 hours at around 20ºC.

Our FAQ answers to frequently asked questions

Possible causes

Too low temperature of ambitne,
Incorrect proportion of base and herdener,
Mixing two components from two different manufacturers

How to prevent

Apply the correct proportions of components
Maintain steady temperature (around 20ﹾC) during whole hardening process,
Mix the products thoroughly and bleed the mixture.

How to remove

The uncured mass requires complete removal from the surface.

If the scratches are not deep, then we can renew the scratched side by polishing with Sea-Line polishing pastes. Above the waterline, when the scratches are not deep, the surface can be repaired with a DRY FAST gel coat filler. Deep scratches should be filled with epoxy filler (selected depending on the requirements of the scratched surface), painted with a primer and then painted with topcoat.

Yes, you can paint the bottom of the boat with polyurethane paint due to its high mechanical strength. We recommend this solution when the boat is not launched for a long time and is not exposed to fouling.
