Applying paint and anti-fouling coating to the hull of fibreglass boats

Applying paint and anti-fouling coating to the hull of reinforced plastic boats

We recommend using an epoxy-based primer for treating the hull of the boat. Epoxy primer protects the hull, extends the boat’s service life and reduces the need for maintenance. Solvent-free epoxy should be used to achieve a sufficiently thick coat. Always follow the manufacturer’s instructions when using epoxy primer.

Do not coat the zinc anodes, sensors or the piston rods of the hydraulic cylinders of the tilt and trim configuration.

In coastal areas, anti-fouling paint can be used to prevent the hull from becoming covered by marine bio. Fouling on the hull significantly increases fuel consumption. An alternative to using anti-fouling paint is to mechanically clean the hull during the boating season. Barnacle larvae, which can be hard to remove after the boating season, are easy to remove soon after they attach themselves to the hull in late July and early August.

Boats that are kept on trailers and in freshwater lakes do not require anti-fouling treatment. Always comply with local regulations when using anti-fouling paints.

Removing anti-fouling paint from the hull

Carefully follow the instructions provided by the paint manufacturer when removing an existing anti-fouling coat. Never dry-sand old anti-fouling paint, as the paint dust is toxic. It is also important to collect all paint waste afterwards.

Avoid using heat for removing paint, as heat can damage metallic paint, as well as rubber and plastic parts.
