COPPERCOAT is possibly the most powerful and long lasting anti-fouling available today. Developed in the 1980’s and available to the public since 1991, COPPERCOAT is successfully protecting tens of thousands of boats the world over, saving their owners the time and expense of annual re-antifouling.

COPPERCOAT is approved for use in California. (California EPA Reg. No. 85396-1-AA) and COPPERCOAT is not considered hazardous; it can be carried on an airplane in your checked luggage as long as it is packaged correctly! Tell us when you order that you intend to take it on a plane.


COPPERCOAT is the combination of a specially developed zero VOC, water miscible epoxy resin and 99% pure copper powder (not cuprous oxide). Each liter of resin is combined with 4.4 lbs of ultra fine atomized copper powder, making COPPERCOAT the strongest copper based anti-fouling available. Indeed no other anti-fouling exposes as much active copper to unwanted marine life as COPPERCOAT.

How can COPPERCOAT reduce my maintenance costs?

You cannot make a better maintenance investment than using COPPERCOAT. Because COPPERCOAT is such a long-lasting and durable anti-fouling coating, you will not need to haul your boat and reapply bottom paint as often as you do with traditional bottom paints. You save money in haul-outs and in the cost to purchase and reapply bottom paint.

COPPERCOAT has an unequaled proven lifespan of 10+ years, with a continual sales record dating back to 1991. No other copper based epoxy anti-fouling has the enviable pedigree of the original COPPERCOAT.

Why do we call COPPERCOAT "the 10+ Year Anti-Fouling"?

The average COPPERCOAT customer worldwide gets about 10 years of protection before they need to do their first touch-ups. That doesn't mean that 10 years is a magic number and you absolutely must do a touch-up; if you are in a mild fouling location it might be 12 years or more before you need to do anything. And if you are in a high fouling area and using an aggressive pad to clean the waterline it might be only 9 years.

What do we mean by touch-ups? For most sailboats, the first place to wear is around the waterline or the bottom of the keel. On powerboats, it is along the waterline and above the propellers. When these areas wear through (you will start to see through the COPPERCOAT to the layer beneath) you will need to haul the boat, sand ONLY the worn areas, and apply COPPERCOAT to those areas. You do not need to paint the whole hull again. These touch-ups normally only take 1 or 2 kits of COPPERCOAT and the boat is good to go for another 10 years or so.

One of the first boats with a COPPERCOAT bottom that we touched up here in the US (after getting EPA approval in 2009) was an Oyster 46 which had the COPPERCOAT applied 11 years earlier. The owners had spent 10 years in the Caribbean before sailing north to Newport, RI where they hauled out to do some other work and to touch-up around the waterline and a small spot on the leading edge of the keel. We did this touch-up using only 2 kits of COPPERCOAT after 11 years of service. That is extremely cost effective.

COPPERCOAT has proven to be very effective on propellers when they are properly prepared. In 2013 we started testing Coppercoat on props. We found that if we sandblasted the metal to get a proper anchor profile and then applied 2 coats of epoxy barrier coat before applying the COPPERCOAT it worked well. We don't claim that COPPERCOAT will last for 10 years on your propeller, but we do know that it is lasting 3 to 4 years before needing a touch-up on the tips of the blades. Follow the instructions in the “Coppercoat Do’s & Don’ts” for applying barrier coatings, partial mixing, and mixing and applying the Coppercoat.

We have talked with a number of happy boat owners that have had COPPERCOAT on their hulls since 1992 and 1993 - that's 20 years!
