Hydrocoat contains drag reducing PTFE and dries to an easily burnished slick film for maximum hull speed. Plus, the controlled erosion of ablative paints reduces coating buildup while the loading of cuprous oxide content combats marine growth in highly fouling waters. Thus, a hull which uses Hydrocoat should only require a simple pressure wash upon haul out to remove growth and prepare the hull for recoating and launching.
Hydrocoat contains cuprous oxide. As a result, 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. When spraying, do not thin Hydrocoat more than
10% (12 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 sponge or very
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
self-cleaning nature of the coating is most effective when the boat is used
periodically. Burnishing of the surface to create a slicker finish should be done with
400-600 grit wet-or-dry paper after the coating has dried for seven (7) days.

What do i thin it with

We just had our bottom soda blasted and are planning on using Hydrocoat here on the Chesapeake Bay. What must we do to the clean bottom before painting?
Use a dewaxer like Totalboat Dewaxer on a cotton rag, wipe a small area go right after with a clean dry cotton rag to remove, then apply bottom paint or a barrier coating first if you want to protect the hull.

Weight of 1 gallon of paint?
About 19 lbs.
Pretty much the same as any gallon of paint
Barnacles are a big problem in Salt Pond area of Rhode Island. Had been using Interlux Micron CSC on hull, rudders and tabs which worked well only on the hull. Tabs and rudders were like a magnet for barnacles. Props and shafts were too but Pettit Barnacle Barrier paint worked great this season. Pettit said I should switch to Hydrocoat on hull, tabs and rudders. Said barnacle problem will go away on metal parts. Does anyone have experience with Hydrocoat in the Northeast with respect to barnacles on tabs and rudders? thanks, John
Thank you Rick for your quick reply. Does it also keep the barnacles off the metal such as tabs, rudders, pods, etc? I know it won't work on shafts or props as it is ablative and gone fast.
yes, everywhere you put it, no barnacles, stainless steel ladder braces etc.
Have been using it for 5 years now and it does keep all barnacles off the hull. Easy to re-coat, light coat at beginning of year, take boat out late October and still no barnacles.I believe OHM in Charlestown Pond uses it as standard coating on all boats it bottom paints.
works pretty well on wood hull and rudder but not as well on metal shaft bearing housing.
I had great results on a glass hull, but was told not to use it on metal.
can i apply over CSC?
I applied my hydrocoat over a previously painted hard coat. I got two years with only lite growth I'm happy with the hydrocoat.
Yes. I did it on two different hulls with no prep beyond pressure washing. Easy application and both have lasted well.
What prep. Is needed when re coating ?
if the service is in good shape a light sanding only
simply power washed, scraped, sanded bottom. Applied single coat interlux ACT, over that applied Pettit Hydrocoat. Bottom seems very slippery in water and gained about a 15% improvement in boat speed
Bronze is not an option in the drop down menu. How do I order a quart of bronze hydrocoat?
Sorry, the bronze color is no longer available.
My experiance says that there is no bronze. You need to call Pettit or go on their websit.Jim
How much bottom paint will I need for a 37' Tayana sailboat?Also, with the pettit Hydrocoat product will I need a primer?
About 2 gallons for 2 coats. To paint old, hard antifoulings, thoroughly wipe down the surface with 120 Brushing Thinner, paying particular attention to waterline areas, then sand painted surface with 80 grit sandpaper. Wipe clean of sanding residue with water and apply Hydrocoat. Old tin or copper copolymers or Teflon based antifoulings should be sanded thoroughly with 80 grit sandpaper to remove the chalky outer surface, wiped clean of sanding residue, and then may be over coated directly with Hydrocoat. Traditional, soft antifoulings should be removed before applying Hydrocoat.
I have a Catalina 320 and 2 gallons is plenty for two coats.I did not use a primer and did my last paint job in 2011. Although they recommend painting more frequently than that, The bottom looked great and cleaned up with nothing more than a good power washing. I am currently in the process of painting the bottom now and am using Hydrocoat again.By the way, I sail in an inland fresh water lake.
My 40' beneteau uses right at 2 gallons; any excess I used for touchups later. If the hull has never been painted, I would lay a barrier coat before the Hydrocoat. Otherwise, a primer is not necessary. Good stuff, BTW.
what is the longevity of your paint?
I used this product on my boat spring 2013. I'll take close look at it this spring before launch, but assuming not doing anything until next year. The boat is in fresh water from April through early November. So 3 years to answer your question.
I used this paint on my 1980 Sea Ray Sundancer that was blistering and pealing after 32 years of service. The vessel was sanded clean and I applied 3 thin coats in April 2013. It still looks impressive after all those times in and out of lift, however, the trailer rollers will leave marks. Over all better than average but I wish that I would have used a slick finish rather than something with a slight texture when dried. The sanding took weeks to accomplish but application was easy. Good luck.
I have a tuna boat and fish the mid-coast area of Maine from early June to mid-October. I've been getting three seasons from this paint with minimal Spring touchup.
I repaint every year. Our boats are kept all summer long in a high growth salt water inlet. I'm very pleased with hydro coat. We never see any growth so a yearly repaint ,to me, beats having to do any scraping at season's end.
Been using this paint for years, lasts a long time but refresh it every year. The local marina in Charlestwon installs this as standard within their facilities if I recall. Good coating, still use it.
I use it as touch up over the bottom paint that came on the boat which was Seahawk. I used Seahawk at first because the dealer had given me a gallon when I bought the boat. I didn't like it and tried the hydrocoat because of easy clean up. It is the best bottom paint I have ever used. I always used the Micron CSC on my other boats but the Hydrocoat is better. This is my second season using it on my power boat. Cruising speed of 10-12 knots. It stays where I put it and doesn't come off when they power wash it at the end of the season. I would definitely recommend it.
I use it on the bottom of a 1950 22' Chris Craft Sportsman. I recoat every year, but probably don't need to. Really like the paint and have used it for 5 or more years now.
Sorry, really can't help. The paint went on very well and covered well. But, the boat has remained in storage and hasn't made it to the water. Paint still looks like it did 2 years ago.
Good paint but we pull and paint each season.
2 seasons in the Ohio River in Cincinnati and no issues!!Great paint and Value
love the stuff
can roll or spray
Very good protection for northern Chesapeake.
Coverage is good.

Be careful when changing to Hydrocoat !!!
Started using it over power washed Micron csc when it first came out. End of season results are large size pieces peeling off. I sanded bottom down last year again then power washed and still peels. Boat kept in partial brackish water but mostly salt in Bpt harbor. Sorry i ever started using.
Was verybeadybto apply and clean up was do easy ... Just dos and water

This is the second time using this paint. We boat on the Chesapeake Bay. Boats around us in the marina have a slime build up along the water line. We don't!!! Lasted 2 seasons. This year I spent about 15 hours sanding the bottom, wiping down and applied 2 coats. We'll be good for 2 years. I also use it on my props, shafts and rudders. Had a diver on it half way thru the season. We had less build up than our neighbors who used the zinc paint.

This was my first time using a water-based paint and an ablative paint. I had always used Petit Trindad. Hydrocoat was easy to apply and the clean-up was a breeze. The only problem I encountered was with the shipment. Although the box was clearly marked with the correct side up, somewhere in shipment, it was turned over. I discovered about 3/4 gal of drying paint in the bottom of the shipping box when I opened it to paint. JD refunded the price of one gal but I had to quickly drive to West Marine and buy another gal of Hydrocoat for $40 more! Not happy about that.
Excellent Product !
Bottom painting a boat is never fun -- but this takes a lot of the mess out of it.
Very pleased with this bottom paint
Used many years ago and found it to be a good product. Use on racing sailboat. Can be polished and with good preparation is a fast finish. Went to traditional ablative paints and did not have as good a results. Went back to it this past season and had minimal growth in a very high growth area and was able to keep the bottom clean and fast with minimal effort.

Some of the comments are too basic here. Such as reduces build up! Well, yes all ablative paints are, that's the point. Hyrdocoat is easy enough to apply I give you that. But be careful as once you apply a water based paint, you can not switch to other ablatives such as Micron 66 or Ultima SR. After a season of using the paint I've noticed that the surface had way too much slime and dirt. It took a long time with a powerwasher to clean it. Once it was cleaned the paint revealed a very dull color that had algee like green patches. Originally, I decided to use the paint for environmental concerns. That said if it doesn't function then I don't have much use for it. Over the years I used Ultima SR 60 and Micron 66. Out of those Micron had the best result in NYC area where I keep the boat. I wanted to apply Micron after Hydrocoat trial last year, but I realized I can not. Do yourself a favor, if you have a large vessel apply expensive paint and you'll get at least two seasons instead of one and it will end up being the same if not cheaper in cost comparison. If you have a daysailor, or a boat that you can haul out and wash from time to time then great use Hydrocoat. For all others, I would encourage you to be more cautious.

I won't use it again
To other comments - looks great when applied, applies easily and easy clean up. I keep the boat downstream from a sewage treatment plant. Hi growth, brackish area. The area a bottom paint manufacturer must hate. The product hands down is the worst protection I have yet encountered. ALL others I have used have been better! AWFUL slime, buildup AND barnacle protection. Their zinc spray works great - the Hydrocoat - awful. My diver said the same (had to clean it twice!) - said another boat with Hydrocoat equally bad. Out of the water - it looks pretty good again - post power wash and had scraping of barnacles...
