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.
Application Method: Brush, roller, airless or conventional spray.
Number of Coats: 2 minimum with additional coat at waterline recommended.
Dry Film Thickness per Coat: 1.5 mils (3.75 wet mils)
Application Temp: 50Deg F. Min., 90Deg F. Max.

How is this product different or the same as your inflatable boat bottom paint? Can I use it on my PVC inflatable bottom?ThanksJim
I have used it on my inflatable dingy and it works and holds up quite well, except for where we drag it across the sand.Good luck
Can Lacquer thinner be used to thin out Hydro coat
DO NOT use lacquer thinner with Hydrocoat. Hydrocoat is water based and should be thinned only with water.

99% sure it's water you want to thin with. Should be instructions on canBrooks
I wouldn't think it. Buy another gallon.
I have no idea.This is a water base paint, use water
It is water based, not solvent based. Lacquer thinner is entirely incompatible with it. I would suggest that you read the application instructions before making a purchase to ensure that the product is compatible with your needs.
I've never thinned it down.
What's the best roller to apply this with, foam or fiber? The can says 3/16 max roller thickness.
I use fiber and it works well-----------------------------------------From: "JamestownDistributors"
I have used both. You get more paint on the surface with fiber.
I use a fiber roller with good results.Nautically,Todd R. HurleyPresident/CEOUSMM CaptainHurley Marine, Inc.906.280.TODD (cell)
Hi LK,I have always preferred fiber rollers.They seem to hold and deposit more paint, and they get into texture better.The foam doesn't seem to absorb as much.Foam is good when you want to apply very little material.Bottom painting doesn't fit into that category for me, although2 thin coats are a good idea when building up the bottom paint surface.Either roller will do that for you.Good Luck!
I used a fiber roller and it performed well.Larry Murray
I had great results using a 4" wide foam roller to apply the Pettit Hydrocoat bottom paint.
I've used the standard 3/8" roller with no problem (fiber). I do however "roll out" on the tray then work a larger section (go on light then press harder as you go) applies an even coat and holds more bottom paint. I then go back over the area again to pick up any heavy spots. Again the purpose is a thin coat, you can put it on to heavy using a 3/16" roller as well, so as long as your doing a thin coat your good. I've never had any issues doing this in the last few years, and it's held up great during the season (slipped for 6-7 months)

I think I used a thicker roller, probably 3/8". The bottom of my boatisn't all that smooth, and I wanted to glop it on and get the boat in thewater. It did run some and dripped on my face while I was under the boat,but I got the job done. After some time in the pan, the paint gets alittle thicker and goes on better with a thicker roller like I used. But Iwouldn't say the roller thickness is very critical.
Hi LK, roller type is more of a preference thing. Some people like foam, some like nap rollers, some even use mohair. They have engineered the paint so you do not need a larger roller thickness than 3/16" to apply it properly.

Can I paint this over VC17?
No, it must be completely removed before applying.

Is one quart enough for a 15' wooden boat?
Yes, it should be.

What do i thin it with
JD Tech Team
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?
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
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.
I had great results on a glass hull, but was told not to use it on metal.
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.
works pretty well on wood hull and rudder but not as well on metal shaft bearing housing.
yes, everywhere you put it, no barnacles, stainless steel ladder braces etc.
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.
Weird experience but got the job done!
I put Hydrocoat on my 32' cruising sailboat 3 years ago and it worked well. Deceided to use it again and it had the consistency of organic peanut butter. Took 15 minutes of determined mixing and got it mixed but it would not roll on well. Clumped up and I had to sand it off! Talked to JD rep and he said to mix it 1/1 with water and stir it well. I did 1:2 and it worked! Went on well and looks pretty good. Directions on can said no more than 10% thinner. Used a gallon on a 32' boat.
Great bottom paint!!!
I first use this product in 2009 on my 40 foot trawler. Cruise for 4 years extensively in the Gulf of Mexico a very harsh environment. The bottom paint performed beautifully with very little growth on pull out after 3 years. The shrimpers at the Boatyard I pulled out at we're blown away with the performance. So easy to clean up I'll use it for everybody um job in the future.

The product worked well but I needed to reorder because I needed more than one coat.
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.
