I have met others who have made DIY copper coat using regular laminating epoxy. The anti-fouling properties were apparently not good. I think there is a reason that Copper coat uses a water-dispersed resin.
Thanks Albert. Still just using the phone mic in this episode. So the sound should get even better in the future with my new mics. Based on feedback from you and others I increased the voice volume and decreased the music volume. Again thanks for the comments. 👍🏻
It does work! When immersed sea water attacks the exposed pure copper powder, causing the formation of cuprous oxide. This is a highly effective antifouling agent and puts off growth until the surface degrades further to become cupric hydrochloride. This final copper form is highly unstable, and is washed away by the movement of the yacht, thereby removing any accumulating silt or slime. This automatically reveals a fresh copper rich surface, whereby the process recommences. I had some weed growth but as soon as I started sailing the yacht the weed fell off. Worst case I will have to re-sand and expose some fresh copper.
@@dapman2007 your binder is a 2 part epoxy which is strong and rigid and it does not degrade, trapping the copper and rendering it inert......outhauling is too expensive to justify using an underperforming antifouling which is all you have
@@jean-philippepollonais1104 that would possibly be true if the surface had not been sanded after application. The purpose of the sanding is to expose the copper with the copper exposed I would propose it is no longer inert. I will do a video today to show the state of the hull. The boat has been in the water for 10 months. She did hardly any sailing for the first 8 months. She has been used a lot in the past 2 months. When I left my home port at the beginning of September there was some weed growth. It has been a very good year for growing weed! I will film the hull today and give an honest appraisal of the situation.
@@dapman2007 the point is that antifouling is self ablative and requires no sanding and thus you have an underperforming antifouling which is unviable when out hauling costs are considered
Well done, this is another aspect of sailing that really needs to have the BS cut on it.
Awesome Job Des. I am now convinced that this is what I want in stead of propspeed. Thanks for the video.
Cool stuff
Des this is awsome im about to attempt the same project so thanks for the wonderful tips!
I did an update vid recently which you can watch and see how it has performed in the first six months or so 👍🏻
Nice work Des. Lots of work but it looks like it paid off.
Hopefully the sticky seafood doesn’t like the taste of my cooper
I know I’m behind on your videos, but let me say that just looks amazing.
Thanks Patrick appreciate you comment. Definitely getting there.

Man, that looks good Des! - Steve -
Thanks Steve, with the prep and all it was a hell of a job!!
@@dapman2007 Can't wait to see effectiveness. How much material did you wind up using? How long is your boat?
The boat is 34 feet. I used about 8kgs of cooper and 8 kgs of resin.
Rolling with an extension to the handle will be easier and faster. Some telescope. You might want more than one.
👍 Nice job Des, looks like copper coat to me! Hopefully you won't need to do the bottom again for years!
Thanks Dan! Hopefully it will work. I’m 95.27% sure it will
Does it work after more than a year?
Very well done episode, Des. I guess you are using a new microphone; the small owl and you are very easy to understand even for me.

You needed to add some thinners to make it easier to apply , and once dry and hard a light rub with some wet n dry to open up the copper
Simply measure,if it is off it's so close ,don't worry it will be in the water
So you sanded then mixed epoxy resin and added the copper powder. Then rolled it on. How did this work out over 2 years thank you
I bet you after 1 season you will not bother with a boot top. Just another maintenance item. 👍🏻
I think you are right. As long as it looks okay! Which I’m sure it will. 👍🏻
Nice work, do you put thinner to the epoxy? I ask me always if this will work also with hartantifouling and copperpowder.
won't work because it won't ablate (copper will be trapped in the epoxy lattice)
