Pettit Hydrocoat Eco Ablative Antifouling Paint


  • Easy application and cleanup with soap & water
  • Water-based, copper-free, self-polishing ablative antifouling paint
  • Co-polymer ablative technology eliminates sanding and paint build-up
  • Dual-biocides provide outstanding multi-season protection in all conditions
  • Uses the power of organic ECONEA™ for better protection and a greener earth


The Hydrocoat name has been synonymous with groundbreaking, waterborne, marine ablative technology for almost 20 years. Hydrocoat Eco is the newest member of Pettit’s exclusive water-based, copolymer ablative family of bottom paints. Hydrocoat Eco is already shattering the perceptions of what an antifouling paint can be. Hydrocoat Eco incorporates Pettit’s exclusive self-polishing, water-based, ablative technology with a completely organic biocide, Econea. The highest level of metal and copper free biocide on the market is combined with a powerful slime fighting inhibitor that includes unprecedented multi-season protection in tough marine environments. Hydrocoat Eco’s co-polymer ablative paint film slowly wears away with use, allowing for a controlled release of biocides while eliminating paint build up and the need for sanding between coats. Hydrocoat Eco is effective in and out of the water. With no copper to cause galvanic corrosion issues, Hydrocoat Eco is the perfect choice for bronze IPS and jet drives, outdrives and outboard motors.

Use water to thin if necessary.

Previously Painted Surfaces: To paint old, hard antifoulings, thoroughly wipe down the surface with 120 Brushing Thinner, pying particular attention to waterline areas, then sand painted surface with 80 grit sandpaper. Wipe clean of sanding residue with water and apply hydrocoat Eco. Old tin or copper copolymers or Teflon based antifoulings should be sanded thoroughly with 80 grit sandpaper to remove the chalky outer surface, wiped clean of sanding residue, and then may be over coated directly with Hydrocoat Eco. Traditional, soft antifoulings should be removed before applying Hydrocoat Eco.*The above dry times are minimums. Hydrocoat Eco may be recoated after the minimum time shown. There is no maximum dry time before launching.

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 D-95 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 or three coats of Hydrocoat 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. Use a 3/16” or less nap when applying by roller. Consult the primer label for complete application and antifouling top coating instructions. Apply two or three coats of Hydrocoat Eco.

Easy 2-Step Sandless Method - Thoroughly clean and prep hull using 92 Bio-Blue and a Scotch-brite pad as described above. Make sure that the entire surface has a dull, frosty finish. Wipe surface to remove any excess moisture and apply two coats of Hydrocoat 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 Hydrocoat Eco.

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

Bare Aluminum: Sandblast to clean, bright metal and remove blasting residue with clean, dry compressed air or a clean brush. Immediately apply three coats of Pettit 4400/4401 Aluma Protect Epoxy Primer followed by two finish coats of this product. Read and follow carefully the instructions on the Pettit 4400/4401 Aluma Protect Epoxy Primer label. If the surface to be painted is smooth aluminum, apply one coat of 6455/044 Metal Primer and allow to dry for 2 hours, then
apply two finish coats of this product. Read and follow carefully the instructions for application and top-coating on the 6455/044 primer label.

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

Steel Hulls: To remove loose rust and scale from the metal surface, scrape, sandblast or wire brush. Solvent clean the surface to remove grease and dirt then apply one or two coats of Pettit 6980 Rustlok* followed by two coats of Pettit 4700/4701 High Build Epoxy Primer. Follow with Hydrocoat Eco.

Underwater Metal Parts: Abrade to clean bright metal by scraping, sandblasting or wire brushing. Solvent clean and apply one thin coat of Pettit 6455/044 Metal Primer*. Let dry two hours and apply two coats of Pettit 6627 Tie Coat Primer*. Let the second coat of 6627 Tie-Coat Primer dry at least four hours and apply Hydrocoat Eco.
