Antifouling bottom paint for boats contains copper compounds or other biocides to deter growth of marine organisms on your boat's hull, helping to keep your boat clean and fast. Defender carries all major brands.
We stock copper-based bottom paints, copper-free paints with biocides, and water-based anti-fouling bottom paints as well as bottom paints with anti-slime additives.
Ablative Bottom Paint
Wears away with use, exposing new biocides
Good for impeding marine growth, but requires the boat to move often to work best
Use in high fouling areas, or if the boat is hauled out every season
Use of a "signal coat" is recommended. A signal coat is a bottom paint of a different color than your final coat. When the signal coat shows through, it's time to consider repainting.
Hard Bottom Paint
Active ingredient leaches out while paint film stays mostly intact
Long-lasting, adheres well, abrasion resistant, works equally well at the dock and underway
Recommended for boats that regularly run at high speeds or are in water for extended periods
Also recommended for trailered boats as it can better withstand abrasion from unloading, loading
Water-based Antifouling Paint
Has fewer VOCs, less odor, cleans up with soap and water
Safe for use on inflatable boats
Hybrid Bottom Paint
Offers all the advantages of ablative and hard paints
