Applying antifouling paint to your yacht is a critical aspect of vessel maintenance. It not only extends the durability of your yacht but can also cut down fuel consumption by up to 5%. Let’s walk you through the seven straightforward steps to protect your boat from marine fouling.
1. Safety measures
Before starting any project, safety should be a priority. Antifouling paint can pose risks if proper safety guidelines are not carefully observed. Make sure you perform the task in a well-ventilated area with the right personal safety gear, such as:
- Protective eyewear
- Nitrile gloves
- A face mask to cover your nose and mouth
- Protective clothing that leaves no skin exposed
Always adhere to any local regulations for the workspace you’re using.
2. Preparing the surface
Start by giving your boat’s hull a thorough pressure wash to remove grime, loose barnacles, and seaweed. If the old coating is in poor condition or if there’s a buildup, remove it using a stripper or by hull blasting. Neglecting this step can result in delamination, blistering, or a decrease in antifouling performance.
3. Masking
Identify and mask the areas you plan to paint. Investing in high-quality masking tape can save you significant time.
4. Necessary Repairs
Examine the hull carefully for signs of damage, such as peeling or separation. If you notice any damage, you may need to carry out fairing and filling. Look out for signs of gelcoat damage and osmosis, and handle them as needed.
5. Applying Primer
A primer is essential for bare surfaces and aids in the adherence of the antifouling coating to the hull. Some primers enable multiple coats to be applied in a single day. Certain primers may also serve as a sealant between old and new coating.
Before proceeding to the application, keep these two crucial points in mind when buying antifouling: Different antifouling coatings are suitable for different water types and types of sailing activity. If you’re uncertain about your antifouling needs, get in touch with us.
6. How much paint do I need?
Refer to the manufacturer’s guidelines to determine how much paint your hull requires. Avoid applying less than the suggested amount to save money. Frequently, people skimp on applying the correct number of layers or the appropriate thickness and regret it later. Use a paint thickness gauge to ensure correct application.

6. Applying the Paint
Make sure the antifouling coating is well mixed with a stir stick as some ingredients may settle at the bottom while the can is in storage. If possible, apply the paint during late morning or early afternoon to avoid moisture or overnight dew. As stated earlier, apply the recommended number of coats and always achieve the required thickness.
Applying an additional coat to areas that experience more water turbulence, such as trim tabs, outdrives, keels, and rudders, is advised.
7. Enjoy 🙂
Antifouling paint performs better when the boat is in use, so the more you sail, the more effective the antifouling will be.
Now, enjoy your time at sea!
