Plastic Sanding Block

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.

Yes, you can paint the bottom of the boat with polyurethane paint due to its high mechanical strength. We recommend this solution when the boat is not launched for a long time and is not exposed to fouling.

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.
