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.....

      Comments about Pettit Z-Spar Pettit Hydrocoat Antifouling 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.

        Comments about Pettit Z-Spar Pettit Hydrocoat Antifouling Bottom Paint:

        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.

            Comments about Pettit Z-Spar Pettit Hydrocoat Antifouling Bottom Paint:

            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...
