Tech Spec Product Info User Generated Content
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.

There is no maximum drying time before launching.

Great results in the Northeast


I was a faithful CSC user for 30 years. Three years ago I changed over to Hydrocoat during our last vessel purchase. The results have been great. Hull is nice and clean after fall wash down each year.

Have not had boat in water


Went on very nicely, but don't know how it will hold up reason for only 4 star. Have not had the boat out yet to try.




My Future Bottom Paint


I have only put a section of this paint on a small area I sanded down to the gelcoat just to test it out. The paint flows on beautifully and working with a water-based bottom paint is so much nicer than the traditional paint. If it holds up this season, it will become my "go to" bottom paint on both my boats.

Will not purchase again.


I will be requesting a refund for 2 qts of this which was unusable. Paint was separated top third liquid bottom 2/3 was a tar ball. No amount of mxing would re-emulsify, just created smaller tar balls. Two previous years it was great. No new bottom paint on SeaWolf this year as launch is 5/20 8am.

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.
