Pettit Ultima Eco Ablative Antifouling Paint

Ultima Eco combines the breakthrough, metal-free Econea biocide with a powerful slime fighting agent for dual-biocide, multi-season protection. This copper-free formula can be safely used on all substrates, including aluminum. It provides excellent antifouling protection, with an ablative surface that makes it the perfect choice for both power and sailboats. Ultima Eco’s surface wears away over time, eliminating paint film build up and the need for sanding. It can be used on almost all previously painted surfaces in good condition. Ultima Eco contains 50% more Econea biocide than the competition, providing true multi-season performance. One or two coats per season are recommended for optimal performance.

  • Copper-free, multi-season ablative
  • Contains organic Econea biocide
  • Dual-biocides for optimum performance
  • Use on all substrates including aluminum
  • Apply over almost any bottom paint
Colors Available:
  • Ivory

 What is Econea?

Econea is, quite simply, the future of antifouling technology. This copper-free biocide offers unsurpassed protection at very low concentrations. In fact, tests show that antifoulants made with just 6% Econea are as effective as those made with 50% copper. This is great news for boaters who are looking for consistently superior antifouling protection, but it’s also good news for the environment. The Econea biocide breaks down quickly in the environment and its breakdown products are biodegradable. Econea is non-corrosive to metals and is safe for use on aluminum and all other underwater metals.

Pettit's Formula

The potent protection that Econea provides works only against hard growth, like barnacles and zebra mussels. Janssen PMP, the company that manufactures Econea, recommends the use of a second biocide to control soft growth. So Pettit formulated their products with Zinc Omadine, a versatile workhorse in the world of biocide technology. Zinc Omadine is so safe it is FDA approved for use in antidandruff shampoo, yet it delivers real muscle in the fight against marine slime, algae and other soft growth. The powerful one-two punch of Econeaand Zinc Omadine make Pettit's lineup simply the best choice available in antifouling protection

How To Apply

APPLICATION DATA METHOD: Brush, Roller, Airless or Conventional Spray.


DRY FILM THICKNESS PER COAT: 1.5 mils (2.6 wet mils)

COVERAGE: 500 sq. ft/gal.

APPLICATION TEMP: 40°F Min. / 90°F Max.

THINNER: 120 Brushing, 121 Spraying

Temp To Recoat To Launch
90°F 2 HR 2 HR
70°F 3 HR 4 HR
50°F 6 HR 8 HR

*The above dry times are minimums. Ultima Eco may be recoated after the minimum time shown. There is no maximum dry time before launching.

PREVIOUSLY PAINTED SURFACES: If the previous coating is in good condition, thoroughly sand with 80 grit paper then solvent clean with 120 Brushing Thinner to remove residue. Apply two finish coats of Ultima Eco. If the previous coating is soft or in poor condition, remove to the bare surface by sanding or using a paint & varnish remover. Proceed with appropriate bare system as described below. Old tin copolymers must be removed or sealed with 6627 Tie-Coat Primer before applying Ultima Eco. When sanding old bottom paint, always wet sand and take precautions against getting the material in your eyes, nostrils, open cuts, etc.

BARE FIBERGLASS: All bare fiberglass, regardless of age, should be thoroughly cleaned with 92 Bio-Blue Hull Surface Prep or de-waxed several times with Pettit D95 Dewaxer or 120 Brushing Thinner. Sand thoroughly with 80 grit sandpaper to a dull, frosty finish and rewash the sanded surface with 120 Brushing Thinner to remove sanding residue. Then apply two coats of Ultima Eco, following application instructions. Careful observation of the above instructions will help ensure long term adhesion of this and subsequent years’ antifouling paint. To eliminate the sanding operation, prep the surface with 92 Bio-Blue Hull Surface Prep or wash the fiberglass three times using Pettit 95 Dewaxer only. Then apply one thin coat of Pettit 6998 Skip-Sand Primer or 6999 Sandless Primer. Use a 3/16” or less nap when applying by roller. When applying Ultima Eco over 6999 Sandless Primer, apply one coat of a hard modified epoxy antifouling paint such as Unepoxy Standard or Trinidad after the Sandless Primer is ready for top coating; then apply Ultima Eco over the hard modified epoxy. Consult the primer label for complete application and antifouling top coating instructions. Apply two or three coats of Ultima Eco.

BARRIER COAT: Fiberglass bottoms potentially can form osmotic blisters within the gelcoat and into the laminate. To render the bottom as water impermeable as possible, prepare the fiberglass surface as mentioned above (sanding method) then apply three coats of Pettit Protect 4700/4701 High Build Epoxy Primer per label directions. Apply two or three finish coats of Ultima Eco.

BLISTERED FIBERGLASS: See Pettit Technical Bulletin TB-1000 Gelcoat Blister Repair and Prevention Specification for detailed instructions.

BARE WOOD: Sand entire surface with 80 grit paper; wash clean with 120 Brushing Thinner. Apply a coat of Ultima Eco thinned 25% with 120 Brushing Thinner, allow an overnight dry, lightly sand and wipe clean. Apply two finish coats of Ultima Eco. Any metal parts must be primed before applying the bottom paint.

STEEL HULLS: Sandblast to SSPC-SP 6 ‘Commercial’ blast, blow off residue with clean, compressed air, and immediately apply three coats Pettit Protect 4700/4701 following application and recoat instructions. Alternatively, hand sand with 80 grit sandpaper or power hand tool clean, then remove residue with clean compressed air or clean, solvent dampened rags. Immediately apply one coat of Pettit 6980 Rustlok Steel Primer and let dry to a tack free state (usually 30 minutes to 2 hours, dependent on temperature). Then apply two coats of 4700/4701 High build Epoxy Primer following application and recoat instructions. Apply two coats of Ultima Eco.

KEELS - LEAD: Abrade surface to bright metal; wipe clean using Pettit 120 Brushing Thinner. Apply one thin coat of 6455/044 Metal Primer; allow to dry two hours. Apply one coat of Pettit 6627 Tie Coat Primer. Follow with an additional coat of 6627 Tie Coat Primer per label directions. Apply two finish coats of Ultima Eco.

KEELS - STEEL OR CAST IRON: Abrade surface to bright metal; wipe clean using Pettit 120 Brushing Thinner. Apply one coat of 6980 Rustlok Steel Primer, allowing to dry only 1 - 2 hours prior to over coating. Then, if fairing is required, apply Epoxy Fairing Compound followed by one coat of Pettit 6627 Tie Coat Primer. Apply two finish coats of Ultima Eco.

APPLICATION INFORMATION: It is necessary to thoroughly mix the paint before using. If possible shake the can of paint on a mechanical paint shaker. Before using check the sides and bottom of the can to make sure all the pigment has been mixed in. If mixing is going to be done with a wooden paddle or an electric drill mixer, pour off half of the liquid from the top of the can into another can and then properly mix in any settle pigment; then remix the two parts together thoroughly. Adhere to all application instructions, precautions, conditions, and limitations to obtain optimum performance. Refer to individual labels and tech sheets for detailed instructions when using associated products, etc. Do not thin Ultima Eco more than 10% (12 ounces per gallon) or inadequate paint film thickness will occur and premature erosion of the finish will be likely.

MAINTENANCE: No antifouling paint can be effective under all conditions of exposure. Man made pollution and natural occurrences can adversely affect antifouling paint performance. Extreme hot and cold water temperatures, silt, dirt, oil, brackish water and even electrolysis can ruin an antifouling paint. Therefore, we strongly suggest that the bottom of the boat be checked regularly to make sure it is clean and that no growth is occurring. Lightly scrub the bottom with a soft brush to remove anything from the antifouling paint surface. Scrubbing is particularly important with boats that are idle for extended periods of time. The self-cleaning nature of the coating is most effective when the boat is used periodically.
