Preparing Your Boat for an Antifoul Application

To keep your boat performing at its best and looking great, applying antifoul is essential. It helps prevent marine growth from slowing you down and keeps your hull in top condition. But before you get to the painting part, proper preparation is key to ensuring the antifoul adheres well and does its job. Here’s what you need to know to get your boat ready.

Hauling Out & Cleaning

The first step is getting your boat out of the water. Whether using a trailer, a boatyard lift, or a slipway, ensure it is secure and positioned safely. Once it’s out, thoroughly clean the hull. High-pressure washing is the easiest way to remove slime, algae, and loose debris. If there’s any stubborn growth, a scraper or stiff brush can help.

Inspecting & Sanding

With the hull clean, inspect the surface for any damage, flaking paint, or areas where the previous antifoul is coming off. Now is the time to fix any imperfections—fill any cracks or chips and sand down rough areas to ensure a smooth surface. Sanding also helps the new antifoul adhere properly, but be sure to wear protective gear, as old antifoul dust can be hazardous.

Masking & Priming

Once the hull is smooth and ready, mask off any areas you don’t want to be painted, such as the waterline and fittings. If switching to a different type of antifoul or applying antifoul to a bare hull, a primer is recommended. This creates a strong foundation for the antifoul to bond with and improves its longevity.

Choosing & Applying Antifoul

Now for the main event—choosing and applying your antifoul! Different boats and locations require different antifoul types, so ensure you’re using the right one for your needs. Stir the paint well and apply it evenly with a roller or brush. Follow the manufacturer’s drying times between coats, and don’t rush the process—good coverage is essential for the best protection.

Re-launching Your Boat

Once the antifoul is dry, remove the masking tape and check for any missed spots. If everything looks good, you’re ready to put your boat back in the water! Try to relaunch within the timeframe recommended for your antifoul type to ensure maximum effectiveness.
