jay 0 Posted July 31, 2020 Report Share Posted July 31, 2020 I've had Silikon from MPS for two years now and am happy with product keeping in mind there is no perfect solution. I do dive before races to give the boat a wipe-down which is relatively easy using a small 12v hookah. After lockdown and not cleaning for two months it had a fair amount of growth, which wiped off with bare hands. I did have some damage to the bow from a fergie buoy, my fault and since replaced with standard ball mooring, which was relatively easy to repair. Yes - it was expensive, but time it saves me in being easy to clean is worth it for me. Happy to answer questions if anyone wants more specific info. Quote Link to post Share on other sites

Hi Jay, could you advise the size of the yacht, the ballpark cost and what sort of prep was required, perhaps also how long the process took. chrs Quote Link to post Share on other sites

It is priced by the sq meter. Best to speak with MPS about recommended prep. Generally clean off all the old crap and put a nice sealing primer coat on for good adhesion, taking care to get good adhesion on this coating. Leave a few days before the silikon is applied. They did the application in one day. Quote Link to post Share on other sites

We followed the directions in terms of coats etc. Despite lost of use, love and attention and a full clean down a few months back we are getting a lot of growth, more than Ive seen with other products on other boats we've owned. I generally antifoul every two years. Given performance of the Ultra 2 Im looking at alternatives and would welcome any suggestions. We also used Ultra-2 last February. I prepped the boat with lots of sanding (even to the point of using Primocon on the entire underwater surface of the amas) then paid the boatyard to spray the Ultra-2. We then spent the month of March at BOI marina and the bottom had a sea of barnacles like I have never seen before, but I only have experience in the tropics and North America. Dove and scraped...We returned for three weeks in July and they came right back. I've been diving recently to knock them off but the water sure is allot colder now!

Fish 594 Posted August 1, 2020 Report Share Posted August 1, 2020 BoI has a barnacle problem... so its not necessarily the AF, but our EPA did take all of the useful stuff out of AF, incase it harms marine organisms.... many well regarded AF's have effectively stopped working since then. One name brand has withdrawn from the market. Would this silikon wrap work on a prop shaft? our prop speed is a bit buggered, and I'd like to keep the barnacles off, or at least get them off every time I spin the prop... I'm also concerned barnacle growth on the shaft is leading to a buggered cutless bearing, because the growth is blocking water flow over the bearing. Is that likely, or m I just getting paranoid?

I wonder if a wrap would be prone to damage from travel lift slings ? particularly with heavy displacement yachts. MPS supplies carpet pads for the travel lift to protect the wrap so damage is not an issue for my light displacement boat. I think heavier boats should be ok as well, but suggest speaking with MPS on their experience here. The aggressive Bay of Islands barnacles are one of the reasons I went with Silikon. They are seasonal from approx Feb - April when water is warmest. Generally I swim to clean the bottom often enough that I don't get these barnacles with the Silikon, however when I cleaned the boat after lockdown, I did have some barnacles adhering to the silikon. They easily pop off with my finger though with no damage. Quote Link to post Share on other sites
NorthlandYS 1 Posted December 10, 2020 Report Share Posted December 10, 2020 to follow this up which Hempel is better? I think only the cheaper one available in multipule colors? also there is new Altex 60, but it is just about the most expensive option at around 400ish for 4L have also used PPG ABC in the past and i believe thats available at Norsand in Whangarei. on my cat 12 months and 8,000 miles ago i used Petit Hydrocoat on the port hull and Seahawk Monterey on starboard. Both have basically been a disappointment, but the Hydrocoat is very thin in many areas and probably needs atleast a serious touchup ASAP. what are the rules these days for painting on grids/ sand bars. no sanding of course just a litre or 2 to keep that port hull going until i do a haul and likely topsides repaint also in April or May?

To follow up on my earlier post...we sanded back the Ultra 2 a few months back and painted on another lot. The only thing I’d did different was to use a lower nap roller. The new stuff is like a different product working much better than the last lot. Used less paint, was smoother finished too. ex Elly 1 Quote Link to post Share on other sites
