Product Overview

Innovative green antifouling paint combining a slime fighting agent and a dual-biocide metal-free technology

Ultima ECO uses new metal-free ECONEA™ biocide combined with a slime fighting inhibitor for dual-biocide, multi-season protection. This copper-free formula can be safely used on all substrates—including aluminum. It provides excellent antifouling protection for sailboats and powerboats with an ablative surface that wears away with use, which reduces your need to sand at haulout.

Key Features

  • Uses copper-free technology

 Get the right amount of paint:

Boat Type Bottom Paint
10' Dinghy 1 qt.
14' Outboard 1-2 qt.
18' Runabout 2 qt.
20' Sailboat 3 qt.
24' Runabout 3-4 qt.
30' Sailboat 1.5 gal.
32' Cruiser 1.5-2 gal.
36' Auxiliary 2 gal.
40' Cruiser 2.5 gal.
45' Sailboat 3-3.5 gal
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.
