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

    Can I add some thinner to antifouling paint?

    There is a possibility of thinning antifouling, but we do not recommend this procedure due to the risk of reducing the effectiveness of the paint. If it is necessary to thin the antifouling paint, it is recommended to dilute it to a maximum of 0-5% (by volume).

    Why the paint does not have the right flow?

    Possible causes

    • No thinning, wrong thinner or wrong amount of thinner
    • Wrong type of roll or brush (wrong bristle lenght)
    • Applying too much or too Little paint,
    • During painting process temperature was too high or the air was too dry,
    • Incorrect preparation of too porous surface,
    • Incorrect proportion of thinner.

    How to prevent

    • Use a brush/Toller suited to the type of surface or paint,
    • Use thinner which is dedicated to the type of application and paints
    • Use thinning proportions which was indicated by manufacturer,
    • Paint in right atmosphere conditions indicated by manufacturer,

    How to remove

    • Grind, clean and paint again.

    Why are the streaks formed?

    Possible causes

    • Wrong viscosity and spraying technique,
    • Failure to maintain proper evaporation time and thickness of layers,
    • Incorrect spraying pressure,
    • Too low temperature of varnish, surface or space ,
    • Wrong thinner or hardener.

    How to prevent

    • Apply the right type of application method indicated by manufacturer,
    • Use working spray guns,
    • Both the object and material must have room temperature of 20ﹾC,
    • Apply correct proportion of base and hardener.

    How to remove
