Tiller 2 Posted March 13, 2020 Share Posted March 13, 2020 Has anyone out there used Jotun antifouling. have used Hempel not happy with results. any recomendations Quote Link to post Share on other sites
wheels 544 Posted March 13, 2020 Share Posted March 13, 2020 Yes and it performs no better. Most likely you are going to find it the same as Hempels. It is not the various Brands that are the problem, It is that more and more of the stuff that leaves a bad taste in the mouths of the Marine growth is being phased out by the EPA and so not able to be used in Antifouling products. I don't know what the answer is. As older stocks of all the brands run out, the new stocks will perform ever increasingly poorly. If something doesn't happen soon for us recreational Boaters, we may have just as good a result using Wall Paper Paste.https://www.epa.govt.nz/news-and-alerts/latest-news/epa-alert-new-rules-make-some-boat-paint-illegal-to-import/In this article it says,"These paints are slow-release toxic coatings, and when numbers of boats are moored together in marinas and harbours, the substances build up to concentrations that can affect people and the environment."Surely that is going to be a Marina, where you are not allowed to swim or fish anyway and is it really that much of an issue if it is bad for such a small area of environment?

Black Panther 1,776 Posted March 14, 2020 Share Posted March 14, 2020 Into year 3 with coppercoat. Still happy with the product. Cant say the same for the company I had to deal with. Quote Link to post Share on other sites
Winter 42 Posted March 14, 2020 Share Posted March 14, 2020 I know nothing about this stuff, but cold be worth a look. https://www.waterline.co.nz/news/297-new-nontoxic-antifouling.html Stay well, well away from that stuff. I've seen it first hand. Doesn't work, and doesn't come off if you try remove it either... Quote Link to post Share on other sites
ex TL systems 63 Posted March 14, 2020 Share Posted March 14, 2020 I will go to Coppercoat next too. I only need about 5 litres Quote Link to post Share on other sites
Steve Pope 255 Posted March 14, 2020 Share Posted March 14, 2020 A friend had his yacht coppercoated 1 year ago, not happy as it is sloughing off, awaiting a reply from the applicator. Quote Link to post Share on other sites
ex TL systems 63 Posted March 14, 2020 Share Posted March 14, 2020 Probably should do it myself. Have done one cat before. You need to start with excellent preparation and 100% removal of anti foul. The rudders were missed a little and some came off there. Quote Link to post Share on other sites
harrytom 698 Posted March 14, 2020 Share Posted March 14, 2020 Has anyone out there used Jotun antifouling. have used Hempel not happy with results. any recomendations 1995 a couple of tins of Jotun found there way out of the naval base and somehow got applied to my yacht,lasted 3 yrs in tamaki river no problem but next batch was useless,hempels was good but batch we used in 2015 useless,altex no 10 was good but now off the market. copper coat is the way to go but finding a decent applicator is the answer.

Fish 0 Posted March 14, 2020 Share Posted March 14, 2020 We are satisfied with Coppercoat. possible at 6 or 7 years now. We applied it ourselves. Had minor blistering on one side of the keel after 4 or 5 years. We believe that was the shaded side and it was a little damp on application. I would recommend applying it yourself, but read the instructions, wait a week, read the instructions again, think about the application issues, and plan it like a military operation. I think the commercial applicators rush too much, esp with regard to weather, humidity etc Don't bother trying to make your own, the devil is in the detail, even Lateral has tried it and failed. The detail is in the water soluble aspects of the resin, if you use normal resin it flat out wont work (they aren't water soluble) - refer to comments above about doing your reading first, understanding it (actually understanding it all, how it works, how to apply it, how it goes wrong...) Given the cost of preparing the hull (full strip back, re-interprotect etc) trying to use a DIY product is a monumental waste of money and time. The cost of the product isn't that bad, its the cost of preperation and commercial application that adds $$$, more so if you are also paying for a commercial hardstand. It is an absolute false economy trying to save money with a DIY product. If you want to do that, why not make your own conventional antifoul? No one does that do they? In terms of performance, CC is not as good as a top shelf antifoul (with all the old ingredients in it, which you can't get anymore), but we need to clean down every 6 months or so. If I were racing, it would need a far more regular clean, i.e. before any big event. It tends to foul up in maybe 4 weeks, then doesn't get any worse for several months. After maybe 4-5 months the barnacles start, which is what initiates the need for a dry out and clean down. Perfectly good for cruising. But being a hard product, you can dive on it easy, no ablative clouds of sh*t in the water. Oh, and it lasts 10 yrs easy, so no more annual haul out. You still need to do your zincs and running gear, but we do them on grids between tides Quote Link to post Share on other sites
marinheiro 365 Posted March 14, 2020 Share Posted March 14, 2020 Has anyone out there used Jotun antifouling. have used Hempel not happy with results. any recomendations Jotun would have to be to be the worst antifouling ever made. Of the conventional products I am still hearing good reports about Altex No 5 and from one user of Micron AP. As has been discussed previously Micron 66 used to be the gold standard, but Micron 77 is no where near as effective. Good to hear that Fish is happy with Copper Coat, as I have heard first hand from quite a few unhappy users. Common feedback seems to be it is good for about 3 years and thereafter not very effective. Maybe they have changed their brew over time Quote Link to post Share on other sites
Dtwo 157 Posted March 14, 2020 Share Posted March 14, 2020 DIY, just have to get the right size copper powder and right mix. A few practice run and youre away No. Just no. Spend the money and get the right stuff or you are wasting time, effort and money. Quote Link to post Share on other sites

rossd 16 Posted March 15, 2020 Share Posted March 15, 2020 Copper coat 3 years. Limpets, barnacles and rock oysters certainly cannot get a foothold. Bit of weedy stuff ,fairly easy to get off, went right over with a scotchbrite at one point that seemed to improve its effectiveness.few mussels got a hold in the corner between keel and hull.

wheels 544 Posted March 15, 2020 Share Posted March 15, 2020 There is a major point being missed here. The first post (Tiller?) complained about the poor performance of the AF's he has used lately. The question is, what type of AF is being used, as in, straight copper, self polishing, self eroding and Ablative and just what is it that the Boat owner is wanting or expecting his Hull to look like after X many months.For any of the Coatings (OTHER than pure Copper), they have two parts to them to do the job. Copper to stop shell fish growth and biocide to stop plant life. If it is just keeping shell fish off the Hull, Copper Coat and any other product wirh copper in it will work just fine.However, if it is slime and weed growth that is your concern, Copper does not stop it. If you go for Copper Coat, you will still get slime and plant growth and this needs to be cleaned off manually.This is very important:AF coatings, as I listed above, work in different ways, respective of the type. If you sit in a Marina for long periods and yet the Hull seems to be dirty, this could be due to using an Ablative or Self Polishing Coating. These two coatings need decent water speed, ie, boat under way, to have the growth fall off. If you do not take the boat out much, then expect the Hull to be dirty while in the Marina or Mooring if you don't get much water flow. Self Polishing is the only one that self releases the surface keeping itself clean, even in still water.So make sure you are not blaming a poor result on something the coating is not designed to do in the first place.

Fish 0 Posted March 15, 2020 Share Posted March 15, 2020 Good to hear that Fish is happy with Copper Coat, as I have heard first hand from quite a few unhappy users. Common feedback seems to be it is good for about 3 years and thereafter not very effective. Maybe they have changed their brew over time Happy is relative. It is inline with our expectations. The main reason we went with it was reduced cost over its life, and reduced maintenance time (not needing to re-apply AF annually / 2 yearly). The bum is not perfectly spit-polished clean, but acceptable for cruising. If you race regularly, you will be disappointed, but as per the OP, I don't know of a better product for keeping a bum perfectly spit-polished clean now he EPA took out all the stuff that worked.

whitepointer 34 Posted March 16, 2020 Share Posted March 16, 2020 i have been using Altex #5 ablative for the last 6 years, fairly happy with it, 2 years between bottom jobs, boats in a marina but gets regular use. Quote Link to post Share on other sites
