Technical informations

Color

Exposure of a freshly applied antifouling paint to moist air can lead to color change. The discoloration is only superficial and does not affect the effectiveness of the antifouling paint. Due to the content of copper oxide, a small color difference between the parts of the antifouling paint is acceptable.

Application method

Manually:

  • brush
  • roller

Spray:

  • airless spray

    Thinning notice:

    In the case of high temperatures and the need to thin the antifouling paint, a maximum dilution of 0-5% (by volume) is recommended.
    Dilution and the application method directly affect the thickness of the antifouling paint layer.

    Special attention should be paid to obtaining a specific coating thickness (100 μm DTF), which ensures the effective operation of the antifouling paint.

    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 did the polyurethane topcoat become dull?

    Possible causes

    • Too short time for evaporation of the thinner,

    How to prevent

    • Maintain the right conditions for complete evaporation of the thinner,

    How to remove

    • Mat the surface, degrease and apply the paint according to the rule (right conditions and thinning proportions)
    • Polish surface if needed.

    Do you have to paint the scratched side of the boat?

    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.
