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.

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.
