Re: Copper sheeting & CopperCoat anti-fouling
I have been on the road and just able to get back on here are review the questions. I will try to answer as many as I can, if you have a question that I haven't answered please ask again.
Sanding every year? No, when a Coppercoat boat is sanded properly the first time. We have found some customers who haven't sanded the hull properly the first time and
get hard growth; the problem is fixable. The hull just needs to be sanded correctly. This is difficult to do with the boat in the water. I have paid for 3 haulouts for customers who didn't sand enough. We now have a picture of what the correct amount of sanding looks like. I will see if I can get in touch with some of these customers so they can comment here.
Practical Sailor test. When we were asked to be in the Practical Sailor test we asked if we could provide a test panel and were told they would apply the Coppercoat and FOLLOW ALL of OUR DIRECTIONS. They didn't follow our directions.
The difference between Coppercoat, Copperpoxy and Copperclad? Copperpoxy was a very resin rich epoxy which was mixed with copper flakes. It was very thick and difficult to apply. Copperpoxy had to be sanded every year, at least. We talk to people at boat shows who have had Copperpoxy and most admit that it was terrible. We have talked to people that loved Copperpoxy, even after having to sand it often. Copperpoxy was also conductive and caused some issues with electrolysis, due to using copper flake (instead of super fine copper powder).
Copperclad was a copper powder in a polyester resin. The product was sprayed in molds by a number of boat builders. We see customers who have had good luck with Copperclad, but now it is wearing thin (15+ years) and want to know if they can coat Coppercoat over the Copperclad, and the answer is yes.
According to Aquarius Marine Coatings, the makers of Coppercoat, there have been 20 different companies who have made a copper in epoxy anti-fouling paint over the past 20or so years. All of those companies are out of business. Coppercoat has been on the market for 23 years.
Different results. First, a lot of the comments about Coppercoat aren't necessarily Coppercoat. Often people lump all copper epoxy coats under the name Coppercoat because it has been around longer than the other coatings and it comes to mind. I can only comment on the 5 years experience I have selling Coppercoat. Coppercoat requires that you clean it from time to time, we tell our customer that all the time. The cleaning varies by location. Boats in New England don't require as much cleaning on the whole as boats in the Caribbean or a hot harbor in Florida. Most of our customers tell us that their boats don't require any more cleaning than the other coatings where they are located.
Medsailor, can you confirm that "Magician" did in fact have Coppercoat on the bottom and not another copper/epoxy coating. Where was "Magician" located?
Coppercoat has only been available in the US for 5 (2009) years. If you hear of a boat that was coated with a copper & epoxy coating in the US earlier than that, it was probably something else. However, there are many boats in the US who had Coppercoat applied elsewhere 6-20 years ago and the owners are very happy.
Why isn't everyone using Coppercoat? There are several reasons that more people are not using Coppercoat. The first is that Coppercoat is a little more expensive than other anti-fouling paints. Another reason is that in order to apply Coppercoat you must first remove the old anti-fouling paint. You do not need to remove old barrier coat as some people think. You only need to remove the old anti-fouling paint and that adds an additional expense to the application process. Another reason is that a LOT of boatyards don't want you to use Coppercoat. They want you to come back every couple of years for a new bottom job. We have had boatyard owners tell us: "Why should I put your product on a boat? It is going to cost me business down the road". We have also been told "I Love barnacles, they make me money".
I can't speak for all of the boats in the world that have had Coppercoat applied, but all of the boats we have done here in the states we have worked very hard to make sure that they were done correctly. We have been fighting all of the negative comments about some of the other copper/epoxy coats that have been out there and failed.
The picture that Fastbottoms has posted is a boat that we can find no record of having bought Coppercoat here in the states. It is possible that he may have Coppercoat, but it wasn't bought here in the US.
When ever a Coppercoat customer here in the states has a problem I here about it. In every instance when I have been contacted I have tried to help the customer sort out the issues. Over 60% of our customers are "do it yourself" customers and we offer a lot of support to them to make sure that Coppercoat works.
Coppercoat is not for everyone. It is more expensive that most other coatings, but our customers feel that it is well worth the price over the life of the coating. A lot of our customers are cruisers and plan to sail off and not have to worry about trying to find a yard in BFE to do a bottom job.
We call it a 10 year bottom paint because that is when most of our customer began to do the first touch ups on the bottoms. We have found 2 boats this year that have had Coppercoat on for 20 years with one touch up.
If there are more questions please post them or send me a PM. I am happy to answer any questions, I'm not on here often but will get back in a day or so.
