Paint Smart

How to choose and apply the right bottom paint to protect your Sea Ray's hull all season long.

We asked Matthew Anzardo, product manager for leading yacht paint manufacturer AkzoNobel/Interlux, for advice on selecting and applying a fresh coat of paint to your Sea Ray.

How often should a Sea Ray owner repaint his or her hull?

The answer is dependent on several factors, such as the type of antifouling paint you use and where you do your boating. For example, areas such as the Northeast, Mid-Atlantic and Midwest are seasonal and boaters tend to repaint every spring. In other areas of the country, your boat may stay in the water for longer periods of time and may not need to repaint the antifouling as often.

If you’re using a multi-seasonal paint, like one of Interlux’s Micron paints, as long as you have paint, you have protection. Micron wears away over time, eliminating the need for heavy sanding and preventing paint build-up. What we recommend with multi-seasonal paints is to paint the first coat a different contrasting color than the final coat. This way when you start to see the initial color—say, a red or blue base coat—then you know it’s time to repaint.

What are the basic steps involved with repainting a hull?

First, check the compatibility of the product you are applying over what you have. Interlux provides a helpful compatibility chart to help customers find out the basic prep: Check it out here. You may simply need to give your hull a good cleaning and then apply, or it may require some sanding to put the new antifouling on. Most of the Interlux antifouling range is compatible with Fiberglass Bottomkote Aqua, which makes it easier for Sea Ray owners to repaint.

Once you have the antifouling picked out, you’ll want to make sure you tape the waterline with a good tape and then use a 3/8 nap roller and a brush. Make sure you take the proper health and safety measures: wear gloves and eye protection, and you might want to put on a pair of coveralls to protect your clothing.

Follow the overcoating windows and launch windows instructions on the can and on the product data sheets.

What are the benefits of applying an antifouling paint?
The primary benefit of using antifouling paint is that it helps your Sea Ray maintain optimal performance. If you have hard growth like barnacles or zebra mussels, they can affect the performance and handling of the boat by creating drag and can damage the hull. So it is recommended if your boat is going to stay in the water and where fouling is a concern, then an antifouling paint should be used.

What should a person look for when choosing a boat paint?
An antifouling that meets the needs of the boating area. If slime and algae are an issue, you’ll want to choose a product that has Interlux’s Biolux Technology, which will help block these from accumulating on your hull. Also, look for one that meets the “seasonality” of your area (see question 1).
