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 despite the use of antifouing paint the bottom of the boat is overgrown?

    Possible causes

    • Too thin layer of antifouling paint,
    • Choosing the wrong antifouling to type of a boat or yacht
    • Thinning of antifouling paint,
    • Incorrect surface preparation before antifouling application.

    How to prevent

    • Apply the right layer thickness of paint indicated by manufacturer,
    • Choose antifouling dedicated to type of boat or yacht and suitable for the type of water,
    • Do not thin antifouling because of the risk of reducing effectiveness,
    • Careful surface preparations (grinding, clearing, degreasing),

    How to remove

    • Wet grinding, apply new layers of antifouling paint.
    • Use C1 shell and fouling remover.

    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

    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.
