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

Sea-Line yacht paints are designed for painting the surface of boats and yachts made of various materials, e.g. laminate, wood or steel. We do not have a certificate of the National Institute of Hygiene, which would allow the use of yacht paint to paint the tank with drinking water.

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

Sea-Line HARD and Sea-Line self-polishing antifouling are not intended for aluminum surfaces. They include copper oxide, which in contact with aluminum causes galvanic corrosion. Especially on aluminum, we offer ALU-PLUS self-polishing anti-fouling paint, which, in addition to excellent adhesion to aluminum, is also 30% more effective than traditional anti-fouling paints.
