Pettit Hydrocoat SR Antifouling Paint
Hydrocoat SR takes water-based antifouling to a whole new level of performance. Pettit’s Clean Core Technology is combined with an organic algaecide to offer outstanding protection against hard and soft fouling, while lowering the paint’s environmental impact. Hydrocoat SR uses innovative technology to replace the harsh solvents found in most bottom paints with water, providing an easier application and clean up, with low VOC’s and no heavy solvent smell. Hydrocoat SR’s self-polishing surface wears away with use, exposing fresh biocides, while eliminating the need for sanding and paint film build up. Hydrocoat SR holds up to trailering, beaching, and launching. Its unique formula allows unlimited dry time to launch, so you can paint in the fall or winter.

PREVIOUSLY PAINTED SURFACES:
If the previous coating is in good condition, thoroughly sand with 80-grit sandpaper then solvent clean with Pettit 120 or 120VOC Thinner to remove residue. Apply two finish coats of Hydrocoat SR. If the previous coating is soft or in poor condition, remove to the bare surface by sanding or using paint remover. Proceed with appropriate bare system as described below. 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 over-coated
directly with Hydrocoat SR.
BARE FIBERGLASS: All bare fiberglass, regardless of age, should be thoroughly cleaned with Pettit 92 Bio-Blue Hull Surface Prep or de-waxed several times with Pettit D95 Dewaxer. Proceed with either Sanding Method or one of the Non-Sanding Methods below. After the surface has been de-waxed, sand thoroughly with 80-grit production paper to a dull, frosty finish and rewash the sanded surface with Pettit 120 or 120VOC Thinner to remove sanding residue. Then apply two thin coats of this product, following application instructions. Careful observation of application instructions will help ensure long-term adhesion of this and subsequent years’ antifouling paint. To eliminate the need for sanding, thoroughly clean, de-wax, and etch the surface with Pettit 92 Bio-Blue Hull Surface Prep using a medium Scotch-Brite pad in a swirling motion. Thoroughly rinse all residue from surface and let dry. Make sure that the entire surface has a dull, frosty finish. Wipe surface to remove any excess moisture and apply two thin coats of Hydrocoat SR.
BARRIER COAT: Fiberglass bottoms potentially can form osmotic blisters within the gelcoat and into the laminate. To render the bottom as water impermeable as possible, prepare the fiberglass surface as mentioned above (sanding method) then apply two or three coats of Pettit Protect High Build Epoxy Primer (4700/4701 or 4100/4101), per label directions. Apply two thin coats of Hydrocoat SR.
BARE WOOD: Bare wooden hulls should be sanded thoroughly with 80-grit sandpaper and wiped clean of sanding residue using Pettit 120 or 120VOC Thinner. A coat of Pettit 6627 Tie-Coat Primer thinned 25% with Pettit 97 Epoxy Thinner should be applied directly to the bare wood. Allow to dry four hours and then apply two thin coats of Hydrocoat SR. Previously painted wood hulls should be thoroughly sanded. If priming is necessary on bare wood spots, apply a touch-up coat of Pettit 6627 Tie-Coat Primer thinned 25% with Pettit 97 Epoxy Thinner to these areas. Then apply two thin finish coats of Hydrocoat SR.
DO NOT USE THIS PRODUCT ON ALUMINUM HULLS AND OUTDRIVES.
Hydrocoat SR 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 SR more than 10% (12 ounces per gallon) or inadequate paint film thickness will occur and premature erosion of the finish will be likely.
Hydrocoat SR is easily applied by brush, roller or spray. When rolling, use only a high-quality short nap (maximum 3/16” nap) roller cover. Apply using thin coats; over-application of this product will virtually assure inadequate coating performance. Mix paint thoroughly to ensure ingredients are evenly dispersed throughout the can. All surfaces must be clean and properly prepared prior to painting. Do not apply Hydrocoat SR on aluminum hulls or outdrives. For the smoothest possible finish: Thin the paint approximately 5-10% with 140 Water-Based Brushing Liquid or clean fresh water. Wet the surface to be painted thoroughly with clean fresh water as well. This will provide a truer color and smoother finish.
