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.

APPLICATION INFORMATION

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.

SURFACE PREPARATION

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.

MAINTENANCE

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.

    We were completely impressed with Hydrocoat. We used it based on other people's evaluation of it on the Chesapeake. It was easy to apply, with a very mild smell, easy to clean up due to the water-based aspect. We are keeping a running evaluation of it over the next two years on our blog, at theretirementproject.blogspot.com

    I would never recommend using this paint or the sr on a wood hull. I have a commercial sailing vessel that sails for 6 months out the the year in brackish water in Florida and is dry docked for the rest of the year. Wanting to have a more environmentally friendly bottom paint with an easy application, Hydrocoat seemed like a good option with all the good reviews. I also called petit, as I was concerned about the application of a water based paint over certain seam compounds, etc, that are necessary to use on a plank on frame. They assured me it would work fine. I did proper cleaning, sanding, etc. and unfortunately, Hydrocoat left a lot to be desired. I had such a huge accumulation of slime that we often had to scrub the side of the hull. We even had some fish feeding off the side! And, this was only within 6 months. The paint did NOT apply well over seam compounds! The paint did NOT protect against marine life well enough to ever want to use it again. Please do not use on your wood hull or in a warm marine environment. It is just not strong enough; back to the real thing.....

                  I have been using Hydrocoat for years. It is an excellent product I have zero build up at the end of an 8 month season in salt water. Great Product and cleans up much easier than mineral based bottom paints.

                      I'm partial to this paint because of it's water clean-up ability. It also does an acceptable job of anti-fouling.

                          I wanted a product which performed well, and the water-based is an added benefit. Shipping was fast, Jamestown price was 40% less than at the local chandelry (two of them), even after shipping. Application is easy, no smell to note, and cleanup is similar to latex paint. I chose to sand prior to application, which is not a requirement. Pettit website has more detailed application guidelines than are included with the product, so check it out. Hopefully I'll be able to continue the positive update after a season.

                          Only downside, Jamestown removes the metal handle for shipping purposes, and this is a heavy can of paint to carry around by its sides.

It is ablative which is important to me to minimize build up and weight - JD had a great price and the free shipping made it the right choice dollar wise

                              This product is very easy to use. Make sure that the paint is well mixed, its best mixed with a drill attachment to mix the paint. Easy to clean with water. I did prior to switching to the ablative was had the bottom sanded down to the fiberglass, barrier coated and then the ablative applied. That was 5 years ago, I applied 2 coats 3 years ago, and again 2 coats this year. No sanding or prep work is needed to apply. I just have the bottom power washed. My boat cruises at 15 knots and from what I understand it is not recommended for higher speed boats.
