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

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.

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.

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).
