Hydrocoat Antifouling Paint
Frequently Bought Together
Hydrocoat’s environmentally-friendly, water-based formula offers exceptional protection against all types of marine fouling organisms.
Lacking the noxious solvents found in most bottom paints, Hydrocoat easier to apply and clean up, with no heavy solvent smell. It is also easy on the environment—and easy on the person who applies it. The water-based formula exceeds even the most stringent air pollution standards for VOCs.
Hydrocoat’s ablative surface wears away with use, exposing fresh biocides while minimizing paint build-up and the need for sanding when the time comes to repaint.
Hydrocoat withstands frequent trailering, beaching, and launching. And with a formula that allows unlimited dry time to launch, you can paint in the fall and splash in the spring.

| 50' Sportfisher | 4+ gal. |
Another way to determine bottom paint quantity is to estimate the approximate surface area of the hull below the waterline, using the following formula:
Length x Beam x .75 = Approximate underwater surface area in square feet.
Each paint has a “theoretical coverage” area, but most paints require at least two coats, so you can expect actual coverage to be no greater than half of the theoretical value.
