7.2 Applying antifouling paint to your boat’s hull

Since your boat spends most of the season in the water, applying antifouling paint to the bottom is a good idea. This special paint prevents aquatic organisms from attaching to the hull, slows their growth, and helps maintain your boat’s performance and appearance.

Risk of injury or material damage.

Chemicals and harmful gases may be dangerous to people or may cause material damage to your boat.

Wear protective equipment when applying antifouling paint. If your paint contains solvents, work in well-ventilated space.

Make sure to read all the labels, data sheet and manufacturer’s instructions and recommendations before starting to apply antifouling paint.

Antifouling may contain biocides. Make sure that they are allowed in the country where your boat is docked.
  1. Remove all hardware from the boat before applying antifouling paint.
    Use tape to cover any items that cannot be removed and may be affected by paint.
  2. Clean surfaces and remove greasy and waxy layers.
  3. Fill and repair any cracks and corrosion.
  4. Sand the boat thoroughly.
    Always sand away all the old paint.
  5. Apply antifouling paint to your boat’s hull.
Antifouling paint wears off gradually over time. Usually it must be replaced annually. Humidity and weather affect how and when the new paint needs to be applied. Make sure to always use the same antifouling paint, otherwise all old paint must be removed before applying a different paint.
