When you see shrinkage between the paint layers of your boat, or the paint detaches completely from the surface of your boat, it is high time to get to work. Always remember to scrape or sand the painted surfaces until you create an even, clean edge; this is important to ensure a smooth overlap. If creating an even edge is impossible, it is recommended to remove the entire topcoat.

Clean the surface thoroughly; remove dirt from the surface with clean water, then putty, prime, and finally apply the correct topcoat as needed.

Remember that antifouling paints should never be dry-sanded, but always wet-sanded. This is an anti-fouling paint, and dry sanding it exposes you to serious health effects.

Most common reasons for paint peeling – and how to fix the situation

• The paint layer is too thick, and the paint shrinks too much
  • Solution: Remember to follow the instructions on the paint can
• There is corrosion or rust on the material
  • Solution: Remember to be careful to ensure that corrosion or rust is completely removed
• There is grease/oil on the paint layer
  • Solution: Make sure the surfaces to be painted are clean
• Antifouling paint has been left to dry for too long
  • Solution: Remember to be careful not to leave anti-fouling paint to dry for too long (unless it is characteristic of the paint in question)
• Pre-treatment was done incorrectly and the maximum painting time was exceeded
  • Solution: Remember to follow the instructions on your paint label precisely
• You have used the wrong combination (1-component paint on top of 2-component paint)
  • Solution: Always use the correct combinations
• Too many layers of paint on top of each other, causing internal tension
  • Solution. Remove old paint accumulations
