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

    Why the epoxy filler does not harden?

    Possible causes

    • Incorrect proportion of base and herdener,
    • Too low temperature of ambient and surface (less than 10ﹾC),
    • Mixing two components from two different manufacturers,

    How to prevent

    • Apply the correct proportions of components
    • Maintain steady temperature (around 20ﹾC) during the whole hardening process,
    • Use base and hardener from the same manufacturer

    How to remove

    • The uncured mass requires complete removal from the surface.

    Can I use universal thinner?

    We do not recommend using universal thinners. The use of a thinner with an unknown composition may result in loss of adhesion, lack of proper flow of paint and varnish defects.

    Why does the paint have no adhesion?

    Possible causes

    • Wrong surface preparation,
    • Skipping the primer in the system application process,
    • Use of universal thinners or replacements ,
    • Paint incompatibility.

    How to prevent

    • Correct surface preparation (grinding, clearing, degreasing),
    • Use primers which improve adhesion of paints,
    • Use thinners which are dedicated to each paints,
    • Use of paints which are compatible to each other.

    How to remove

    • Grind, clean and paint again.
