Pettit Paint
  • Multi-season Ablative
  • Minimal Odor, Easy Clean-up with Water
  • Used on all new Sea-Ray Boats
  • Ablative finish reduces coating buildup through controlled erosion.
  • Complies with all air pollution (VOC) regulations
  • Contains PTFE which reduces drag, resulting in an easily burnished, slick film for maximum hull speed.

The ideal combination of high-speed performance and durability with environmental responsiveness. This product uses water to effectively transfer the paint to your boat. The end result is multi-season protection with easy clean-up and minimal odor.

Hydrocoat is formulated with a 40% cuprous oxide and is tough enough to withstand frequent trailering, launching and beaching. Used by Sea-Ray on all new boats.

All paint colors shown here are for guidance only. Due to differences in screen displays that are beyond our control the colors on these pages cannot be guaranteed to match the actual color in the can.

Hydrocat is a waterbased antifouling bottom coating designed to give protection against algae, barnacles and all types of marine and fresh water fouling. It's waterbased formula results in an effective product that is easy to apply, environmentally responsive (exceeds even the most stringent air pollution regulations) and is safer to use. It withstands frequent trailering, beaching and launching while offering excellent antifouling protection.

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.

Hydrocoat is very easily applied by brush, roller or spray. When rolling, the following technique will help ensure a smoother finish: Thin the paint approximately 5-10% with 150 Easy Brush Additive or clean fresh water. Use 150 Easy Brush Additive to slow down the dry in warm weather. Then wet the surface to be painted thoroughly with clean fresh water as well. This aids the "hold out" of the coating, resulting in a truer color and smoother finish. Slight variations in color and surface texture are not uncommon and should not be viewed with dismay. The surface quickly smoothes itself once in the water and any mottling of the color will diminish as well.


Coated Surfaces: To paint old, hard antifoulings, thoroughly wipe down the surface with 150 Easy Brush Additive, paying particular attention to waterline areas, then sand painted surface with 80 grit sandpaper. Wipe clean of sanding residue with 150 Easy Brush Additive 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 overcoated directly with Hydrocoat. Traditional, soft antifoulings should be removed before applying Hydrocoat.

Fiberglass: Wash the fiberglass with Pettit 95 Dewaxer to remove parting agents, grease and dirt. Sand thoroughly with 80 grit sandpaper to a dull, frosty finish. Rewash the sanded surface with 95 Fiberglass Dewaxer and then apply at least two coats of Hydrocoat. To skip the tedium of sanding, wash the fiberglass twice with 95 Fiberglass Dewaxer and apply a thin coat of Pettit 6999 Sandless Primer. Let dry in accordance with the Sandless Primer label and apply Hydrocoat. Please note that acetone does not readily clean contaminated surfaces and its use as a cleaner/dewaxer is not recommended.

Wooden Hulls: Bare wooden hulls should be sanded thoroughly with 80 grit sandpaper and wiped clean of sanding residue. A coat of 6627 Tie-Coat Primer thinned 25% with 97 Polypoxy Thinner should be applied directly to the bare wood. Allow to dry 4 hours and then apply two unthinned coats of Hydrocoat per instructions. Existing, hard antifouling paint should be thoroughly sanded. If priming is necessary on bare wood spots, apply a touch-up coat of 6627 Tie- Coat Primer thinned 25% with 97 Polypoxy Thinner to these areas. Then apply the subsequent coats of Hydrocoat.

Steel Hulls: To remove loose rust and scale from the metal surface, scrape, sandblast or wire brush. Solvent clean the surface to remove grease and dirt then apply one or two coats of Pettit 6980 Rustlok Primer* followed by two coats of Pettit 4700/4701 High Build Epoxy Primer. Follow with Hydrocoat.

Underwater Metal Parts: Abrade to clean bright metal by scraping, sandblasting or wire brushing. Solvent clean and apply one thin coat of Pettit 6455/044 Metal Primer*. Let dry two hours and apply two coats of Pettit 6627 Tie Coat Primer*. Let the second coat of 6627 Tie Coat Primer dry at least four hours and apply Hydrocoat.
