A question about coppercoat
|
Paul Dowd and Sharon Brown
Hi all,
With Coppercoat, my understanding is that scraping should be done 2-4 times a year depending on where you are. My question is: does it matter of the hull is not scraped for an extended period, say 9-12 months? Would this make it any more difficult to clean the hull later? Or even be detrimental in any way?

I have gone 9 months and no problem. CopperCoat been on for over 3 years now. On another issue. I have changed the the lifting pistons on my windscreen in preparation for replacement. Can’t get to Grenada yet. See photo. I put a centre attachment for easier closing. Calling it the “EZ Close” New pistons are each 150n. I have a 300n piston if anyone who has an early 54 with the single piston needs a replacement. I changed because I couldn’t get a 300n piston.

Hi Paul,
We put Coppercoat on 10 years ago when we were in England . In our first season we went up to Scotland and on to the Med and we have been in the Med ever since.
We were disappointed in our first season as the hull stayed a sort of brown colour ( as originally painted ) and we had some fouling. We then sanded very gently and have not looked back.
We had some rust coming through on the iron keel after 5 years so we had Coppercoat applied afresh on that section by Cleopatra marina in Preveza in the Ionian. ( they did a very thorough job )
We now sail for 5 months of the year, April till June, coming ashore for July and August, then afloat in the autumn and ashore in the winter.
Our Coppercoat is now green. The copper has really come through and is completely effective against fouling. Someone had told me that Coppercoat gets better as the years go by. I took that with a pinch of salt at the time but today I share that view. After
three months in the summer we can detect a slime on parts of the hull but it comes off with a sponge when we are swimming. Med sea temperature in the summer can get up to 27c ( 80F) and was still at 24c ( 75F) last week.
When we lift we are as clean as when we launch.
For us, with our limited number of months afloat, Coppercoat has delivered. For 33 years we antifouled, doing everything ourselves--sanding down, filling patches, painting etc etc. Now that our combined ages approach 143 ( Judy has just reached her 30's )
I look for every labour saving device to complement the best labour saving yacht we have ever owned. Coppercoat has proved one such.

Many thanks to all for the feedback on this. I can now happily leave the scraping until we get back to Grenada.

Can coppercoat be applied by an owner or does it need to be applied by a dealer ? If it can be installed by an owner ,what would you estimate the cost of materials would be . I had the impression that there was mixed reviews on this product,but you guys seem very pleased with it. I have my hull down to the gel coat and ready to apply a barrier coat soon ,so I could go with any bottom protection at this point.
Thanks,
Pat

Hi Pat, check this out https://youtu.be/6JkCzOZ9k_Q they had few failures, but at the end worked out. Good summary on things to watch out for. They have few videos on their saga with copercoat, this is the last one when they finally made it work, if you up for it and have time.

We put our own copper coat on in Trinidad, just the two of us. In the heat it did need thinning down. We did a third of the hull at a time. We did not put a barrier coat on as it is an epoxy mixture itself. This was our advice from Copper Coat Uk. If you go on the website you can calculate the amount you need. The main cause of failure is not continuously stirring the mixture during application to keep the copper flakes evenly distributed in the resin. Another cause is not putting all the coats on immediately the previous one is at the ‘tacky stage‘. Sometimes ‘professional workers’ put a layer on the whole boat Then leave the next coat till the next day.
Our friends did their boat at the same time with one person continuously mixing the next batch while 6 people With rollers continuously applied it. Bottom line is that it is not much more difficult than anti fouling. On the plus side it is water based so cleaning rollers, hands etc it is less messy and less toxic. |

We applied CC ourselves.

It’s not easy. First, CC is not paint. It is a 2 part epoxy with copper powder (more like dust) mixed in. Two factors to deal with: 1) the copper does not stay in suspension. It must be mixed constantly. This takes one person. 2) it’s epoxy. If the weather is warm, you have limited time to apply it before it “kicks”. The constant mixing on a warm day insures a relatively short working time before it hardens in the paint tray, so you must mix many, small batches, and work fast. Lastly, and very important, you must let the CC cure for 4 days on the hard, then sand it. Any epoxy will coat (encapsulate) whatever particle is introduced. Unsanded CC is not anti fouling. You must sand it to expose the copper metal for it to be antifouling. Sanding is a critical step. There are published directions in applying CC yourself. The first step is removing all old paint, and having a very clean hull to start. We are members of the yacht club that the US distributor of CC belongs to, so we had excellent technical direction, and followed all instructions, exactly. There are no shortcuts to applying CC. That said, my wife (the mixer) and I applied it ourselves, doing one side of the hull each day (so two days to apply) and one day to sand, 4 days later. It was difficult, but worth it. We sold the boat two years ago. It’s on its 7th year with no problems. When necessary to repaint, we will have CC applied again. We’ll likely pay someone to do it.....we’re getting old. ~~~⛵️~~~Matt On Oct 30, 2020, at 7:44 AM, Patrick McAneny via groups.io <sailw32@...> wrote:

Oh, CC is about 2X the cost of conventional bottom paint.

Matt, How many coats of CC do you apply. I am fairing some holes in my gel coat and then plan to overcoat with Interprotect 2000. Can CC be applied over a barrier coat?
Thanks,
Pat

Hi Pat - check out coppercoatusa.com - they list an SM as needing 18 "Kits" for $2340. Site is a "must read and study". It is a totally different animal than conventional bottom paint and requires 4 coats applied one after another in one session.

Craig, That sounds expensive, but I spent $1500.00 on bottom paint a couple of years ago. If you got six years for $2300. ,that would work out pretty well,if it works for you ,seems to have had different results for different people ,probably application error.

Yes, CC can be applied over barrier coat. Follow their directions.

I applied four coats as they directed. The coats go on thin and it doesn’t look right until the second or third coat. I can’t over emphasize following their directions to the letter. ~~~⛵️~~~Matt On Oct 30, 2020, at 10:37 AM, Patrick McAneny via groups.io <sailw32@...> wrote:

CopperCoat has been the least expensive antifoul I’ve ever used. Spread that “high” cost across 10 or more years.... Matt ~~~_/|)~~~ A50#27

Does CopperCoat stay in tact when hauling out? Given it is epoxy mix coats, I assume so, but still would like to ask. I use regular ablative water based antifoul and every year my boat has marks from straps. and where the straps go, antifoul paint is mostly wiped off and needs painting.

From my point of view, the elementary problem is that you still have to go to the crane every year to clean it and grind it again so that it works.

Of course, this increases the costs if you don't want to get out of the water every year. My personal recommendation for those with long water times is still the tried and tested antifoulings for 2 or 3 years (Micron, Seajet ..). This form may be helpful for yachts that do not have epoxy protection under water from the shipyard. My personal question is always why is it not used by commercial shipping?

We have hauled every hurricane season to store our boat. CC is a hard epoxy. One nice feature is, when cleaning slime, you can take a 6” metal putty knife to scrape it with no ill effects. Straps won’t affect it. No worries.

We’ve only sanded once, 4 days after application. That was 7 years ago.

Hi Arnold,
We have had no need to clean and grind Coppercoat in the ten years that we have had it , other than occasionally wiping off slime after a few months which we can do swimming.
Have a look at the Coppercoat website--I think you will find that their major market is commercial vessels, oil rigs etc They know about long water times and the huge cost of taking vessels out of use for maintenance.
