Pettit Trinidad SR has been voted the #1 antifouling by trade magazines. This hard modified epoxy bottom paint contains up to 65% cuprous oxide (copper content) for the non-Irgarol formula, and up to 60% cuprous oxide for the formula containing 2% Irgarol—plus slime-fighting biocides.
Trinidad SR is the standard by which other bottom paints are measured. It is the longest lasting, most potent antifouling paint available. With its high copper load and slime resistance, Trinidad SR provides unprecedented resistance to all types of fouling. Its hard, protective coating has excellent adhesion and withstands the toughest abuse. Left in the water, it will provide years of dependable service.
Available in Blue, Green, Red, and Black

Note: The chemical compound behind the highly effective anti-slime additive Irgarol was unavailable for several years. Paint manufacturers substituted additional zinc in its absence to ensure similar antifouling performance. Bottom paints containing Irgarol are once again available, and are recommended for extra protection in medium to severe fouling conditions. SR-21 Blue and Bronze paints contain Irgarol.
Trinidad SR is a hard, protective paint that yields the most durable finish for long-lasting performance that still allows for easy burnishing. It can be applied over most hard antifouling coatings. Be sure to remove old, soft antifouling paint before applying to any surface. Excellent adhesion to fiberglass, wood and steel hulls, but do not use on aluminum.
Trinidad SR is heavily loaded with cuprous oxide. As a result of this there is a tendency for settling to occur, especially if the paint has been on the shelf for several months. It is necessary to thoroughly mix the paint before using. If possible shake the can of paint on a mechanical paint shaker. Before using check the sides and bottom of the can to make sure all the pigment has been mixed in. If mixing is going to be done with a wooden paddle or an electric drill mixer, pour off half of the liquid from the top of the can into another can and then properly mix in any settled pigment; then remix the two parts together thoroughly.
Adhere to all application instructions, precautions, conditions and limitations to obtain optimum performance. Refer to individual labels and tech sheets for detailed instructions when using associated products, etc. Do not thin Trinidad SR more than 5% (6 ounces per gallon) or inadequate paint film thickness will occur and premature erosion of the finish will be likely.
Coating performance, in general, is proportional to the degree of surface
preparation. Follow recommendations carefully, avoiding shortcuts. Inadequate
preparation of surfaces will virtually assure inadequate coating performance.
No antifouling paint can be effective under all conditions of exposure. Man
made pollution and natural occurrences can adversely affect antifouling paint
performance. Extreme hot and cold water temperatures, silt, dirt, oil, brackish
water and even electrolysis can ruin an antifouling paint. Therefore, we
strongly suggest that the bottom of the boat be checked regularly to make
sure it is clean and that no growth is occurring. Lightly scrub the bottom with
a soft brush to remove anything from the antifouling paint surface. Scrubbing
is particularly important with boats that are idle for extended periods of time.
The coating is most effective when the boat is used periodically.
IMPORTANT: The dry times below are minimums. Trinidad SR Antifouling may be recoated after the minimum time shown, and launched up to 60 days after painting.

My current bottom paint is Hempel Globic 9000 which is described as "premium high solids chemically hydrolysing SPC antifouling based on Nano Acrylate Technology, leading low friction properties,self-smoothening, and very fine control of polishing for optimal performance." It is for commercial shipping but the only one I could buy in Colombia. It is very hard which makes me think it is not ablative, but the description is not clear to me on this. Can I use Pettit Trinidad SR on top?
You would have to contact Pettit directly on this. Being an SPC I am not sure you would be able to use this paint even if it is hard, but they would ask the manufacturer.

Does this need to be stripped completely before repainting with another paint? I just bought a boat that has been out of the water for 6 months or so and I need to do some touchups in areas at the minimum. Can I paint over this or does it need to be stripped completely? Thank you.
Depends on what you are repainting with. If it's an ablative you can sand, clean then apply. If you are using one of the silicone based paints, it will need to be removed.

This is the top of the line? How long should it last in Florida?
That is loaded question. We live in Port Charlotte, boat behind house is 42 Solaris catamaran. I usually get 3 years but I also keep in a lift a good part of the time. I see a difference in barnacle growth between the hull against the dock and the outside hull. I generally scrape the props every 3 to 4 weeks. Hope this helps.
I keep my boat in fresh water and the paint lasts three to four years easily. I have no experience with salt water usage of the product, so I cannot say how long it might last in that environment.
There are many variables that affect how long bottom paint will last. Remember, too, that if the boat has to be taken out of the water for more tan a few days the paint must be renewed.In Fort Pierce, FL the condition of the bottom paint upon haul-out, after 2 years, was excellent. It was renewed only because the boat was on the hard for an extended period.

We are in the Chesapeake Bay. We have used this paint for over 20 years. One coat has always lasted one full season. They have changed the formula some this year, but I still expect a full season--no more pulling our skiff up on the beach to scrap the bottom. It is costly, but worth the money for not having to go to railway more than once a year.
WHAT IS THE DIFFERENCE BETWEEN TRINIDAD SR AND TRINIDAD SR PRO? THANKS...TOM
Don't know the difference. I used SR and in Sea of Cortez waters found it lasted less than 2 years. Now using Comex Hard with better results.
I have used paint for years, keep boat in brakish water and pettit paint last for 5 years before i need to repaint.Great paint
I've used it with good success as well. I'm trying to find out what the difference is...
Tom, sorry I'm not sure, but it has been on my boat in the water for over 2 years and is still in good shape.
is this the sAME PETTID TRINADAD THAT i HAVE USED FOR YEARS?
Not exactly. The slime retardant agent has been changed. You can go to the petit website to read more about the change. Petit claims the new agent is as good as the old.
It looks like the old stock containing the biocide Irgarol has been sold out, so the new paint is not the same as you have been using. Whether it will work as well remains to be seen!
They wouldn't sell it to me
Does the trinidad blue come in gals.?
I have not seen this on Market. I painted my hungry 33 using quarts.
I used black in gal but I would think the blue would come in gal.
What is the best pettit bottom paint to use when I keep my 21 ft grady white in the saltwater for 6 months and on a trailer for 6 month ? I live in SW Florda. I also want to put bottom paint on a 35 Ft. Ablin sport fishing boat which I keep on a lift ?
While I have high regard for the SR, it would be overkill for your application. I would pick something less expensive for the Grady White, maybe one of the slippery paints or the ablatives. Regarding the boat on a lift, do you really even need a toxic bottom paint? The idea is that barnacles and the like adsorb the poison (copper) thru their foot and cannot live or don't even try to attach. If there is no water, no growth. It would seem you could get away with no paint at all other than for cosmetic reasons. Nobody paints their dingy bottom if it doesn't live in the water.
I believe that you cannot use hard paint if the boat will be out of the water on a lift or a trailer.
I don't think Pettit Trinidad is a good choice if the boat will spend 6 months each year out of the water. It loses it's effectiveness when left exposed to air. An ablative paint might be a better choice.
I think that the Trinidad SR is the best one ! I use it in 2 years in salt water on the carrebean sea
Aboat yard is telling me they can paint my boat with the Trinidad SR in one day. I read below that it has to cure for a few days before the second coat and that doesn't even include the primer coat. Whats the proper procedure for applying primer on gelcoat then paint?
Jim:depends on a lot, including temperature, humidity, etc. The manufacturer's instruction advise curing for a reason. I painted over two days and the bottom still looks great after 1 year in the water (I dive to check on it regularly). For the price Trinidad costs, I would stick to the manufacturer's suggested application guidelines.
1-dewax gelcoat (even if boat is not new and has been previously bottom coated)2-lightly sand gelcoat to provide mechanical bonding surface for barrier coat (normally an epoxy base)3-lightly sand barrier4-apply Trinidad (temperature and wind are important in drying time)Drying times listed by manufacturer are best to follow. I no longer use Trinidad due to changing fouling conditions on Western Long Island Sound but I found it to be the best in hard growth prevention and yes, I applied the second coat the day after the first coat. The problem is the VOC's in the first coat must be given time to evaporate before applying the second coat or they will prevent proper adhesion.
does Trinidad sr have any advantage over regular Trinidad for long term wet mooring in fresh water?
Bob:I don't know. I purchased the Trinidad SR version because that was the bottom paint the previous owner of my boat had used and it held up well over two seasons. After I repainted the bottom the boat was moored and used in salt water for about 6 months, and then I traded it in for a bigger boat. The paint still loooked fresh when I last saw it. I was generally pleased with Trinidad SR, but have no experience with other bottom paints so can't offer an informed compare.
OK for fresh water?
The copper content in Petit Trinidad is most effective in salt water where barnacles and other critters may attach themselves to the hull. The SR in the formulation keeps slime from forming. For fresh water use you still face algae etc. growing on your hull. This paint would be effective for that. Here on the Chesapeake where I live I leave my boat in the water year round. I haul and repaint with this hard bottom paint every third year. If you live in the Great Lakes region, you would haul every year. I don't know how such an exposure to air affects the biocide in the paint.
I would use product again because I like the results.
Great Product for bottom painting. The new can of paint did arrive damaged, however. I call customer service , sent pics of a pretty beat up can along with evidence of some leakage out of top of can. Text message received back from Jamestown was that it left their facility with no damage and blame was on shipping.
Ocean Isle Beach NC
Only bottom I have used for the last decade.
We are in the southern Chesapeake and can get three years out fo a bottom job with a diver every 3 months doing a wipe down. Very few barnacles and growth.We always sand back some with 80 grit screens and a Porter Cable DA. Two coats.Our Alberg 35 uses about 1.75 gallons so we just buy 2.
I would buy the product again but not from jamestowm
I ordered two cans to store for about five years as copper based bottom paint will not be available in California any more. One can came dented and the best Jamestown would do is give me an empty can to put the paint in for storage. It would be a job to mix the paint and put it inside can for extended storage. I was not pleased with the customer service and I will buy from other distributors in the future.
Great product, great service by JD.
This bottom job will last 3 plus years with Trinidad. Great paint.
Product fabulous: shipping damage - twice!
Product expensive, and MUST be applied according to tech notes. However, shipping was a disaster. Product devastatingly delayed and order not delivered due to 'damage.' Second order arrived, also extensively damaged , barely useable.

I continue to use Trinidad, Because It Works Great!
Have used Trinidad Pro twice and got excellent results (Usually get 3 to 4 seasons per painting. Moored in Potomac River, near Chesapeake Bay). Our 28 Bertram stays in the water year round and in June 2016 I applied two coats of Trinidad SR using a short nap roller (read and follow the tech sheet!), and I am extremely pleased with the results. After two hard barnacle strikes, we pulled boat in July 2017 and only had some slime on the bottom and around the water line, while the shafts and props were coated with barnacles. This stuff is really great, and worth the extra money because it gives multi season protection.

Great bottom paint
I have the bottom cleaned and painted by professionals.I have used this bottom paint since my boat was new in 2005. It has always performed very well. Each time I have the boat pulled to have the bottom cleaned and repainted I am always pleasantly surprised by how little growth there is and how good the paint still looks. It is an excellent paint for inland waterway use and easily lasts three to four years.
Easy to apply, fast, and effective
Very happy so far. The paint was highly recommended for our fresh water lake where slime is the bigger concern. We applied 3 coats, sanded using 320 grit, then we burnished using a DA buffer and bronze wool pads. The result is a super slick race winning bottom and so far (8 months) no slime without any cleaning.
The best bottom paint ever
Great coverage. Lasts long time.
