Pettit Protect Gray High Build Epoxy Barrier Primer Coat
Pettit Protect High Build Epoxy Primer is a heavy duty, two component epoxy coating for use where maximum resistance to fresh or salt water is required. It reduces water absorption in fiberglass hulls, making it an excellent choice for the prevention and repair of osmotic blisters. Pettit Protect’s high-solids formula allows for quicker and easier application with fewer coats necessary for effective protection. Pettit Protect also provides dependable corrosion protection on steel, aluminum, and all other underwater metals. It is ideally suited for commercial and pleasure craft applications and has excellent durability. Pettit Protect has excellent durability in exterior exposures, although, like most epoxies, it will chalk if not top coated.
- Reduces water absorption in fiberglass hulls and prevents osmotic blistering.
- High film build for maximum protection with fewer coats.
- Excellent water and chemical resistance.
- Exceptional protection for steel, aluminum, and other metals.
- High Performance System for Underwater Running Gear.
Pettit Epoxy Thinner: Thinning is not usually needed, but for slow drying in hot weather or windy conditions, small amounts may be added. Do not add more than 10% by volume.
Pettit Brushing Thinner: For cleaning the surface during preparation.
Why Pettit Protect?
Pettit Protect utilizes Mica Shield Technology. Pettit Protect Mica is incorporated into the epoxy resin while in sheet form, where as other competitors use Mica in a ground form. The differences between the types of mica used in epoxy primers is the ratio of the mica particle length to its width. Pettit Protect uses a high aspect ratio mica whereas other competitors use a low aspect ratio mica. The sheets with high aspect ratio Mica are forced to overlay each other creating an impenetrable layer of epoxy.
Pettit Protect high-solids formula saves time and money because it allows for quicker and easier application with fewer coats necessary for effective protection. When compared to competitive products, Pettit Protect’s high-build formula allows for application of heavier coats without it running or sagging while still providing a smooth finish for antifouling paint. Pettit Protect uses less solvent than competition and this reduces solvent smell. Together this results in less labor and less product needed to obtain the Dry Film Thickness (DFT) necessary for the ultimate in protection.

*If these recommended intervals are exceeded, sand thoroughly with 80 grit sandpaper before recoating or applying bottom paint.
BARE FIBERGLASS: All fiberglass surfaces, regardless of age, should be thoroughly cleaned and prepped using 92 Bio-Blue Hull Surface Prep or washed at least twice with Pettit 95 Fiberglass Dewaxer. Change rags frequently to ensure complete removal of wax, mold release, or other contaminants. Sand the surface thoroughly with 60 grit sandpaper and rewash with 95 Fiberglass Dewaxer to remove sanding residue. Apply at least three coats* of Pettit Protect High Build Epoxy Primer 4700/4701 following the application and recoat instructions. Finish with two coats of Pettit antifouling paint.
BLISTERED FIBERGLASS: Refer to Pettit Technical Bulletin TB1000 "Gelcoat Blister Repair and Prevention” for detailed instructions.
BARE ALUMINUM: Sandblast (using non-metallic media) or disc sand the aluminum to clean, bright metal. Wipe clean of residue and immediately apply one thin coat of Pettit 6455/044 Metal Primer. Let dry 8 hours minimum, 48 hours maximum, and apply three coats* Pettit Protect High Build Epoxy Primer 4700/4701 following application and recoat instructions.
STEEL HULLS: Sandblast to SSPC-SP 6 Commercial blast, blow off residue with clean, compressed air, and immediately apply three coats* 4700/4701 following application and recoat instructions. Alternatively, hand sand with 80 grit sandpaper or power hand tool clean, then remove residue with clean compressed air or by vacuuming. Immediately apply one coat of Pettit 6980 Rustlok Steel Primer and let dry to a tack free state (usually 30 minutes to 2 hours, dependent on temperature). Then apply three coats of Pettit Protect High Build Epoxy Primer 4700/4701 following application and recoat instructions. Do not let Rustlok Primer dry longer than 2 hours under any circumstances before applying Pettit Protect High Build Epoxy Primer 4700/4701.
KEELS - LEAD: Disc sand or otherwise abrade surface to bright metal; clean off residue. Apply one thin coat of 6455/044 Metal Primer and allow to dry eight hours. Apply one coat of Pettit Protect High Build Epoxy Primer 4700/4701. Let dry to recoat. Then, if fairing is required, apply Pettit Protect 7000/7001 Epoxy Fairing Compound. Sand smooth with 80 grit sandpaper and follow with two additional coats of 4700/4701 per label directions.
KEELS - STEEL OR CAST IRON: Disc sand or otherwise abrade surface to bright metal and clean off residue. Apply one coat of 6980 Rustlok Steel Primer, allowing to dry only ½ - 2 hours prior to overcoating, no more, no less!Apply one coat of Pettit Protect High Build Epoxy Primer 4700/ 4701. Let dry to recoat. Then, if fairing is required, apply Pettit Protect 7000/7001 Epoxy Fairing Compound. Sand smooth and follow with two additional coats of 4700/4701 per label directions. Previously Primed Surfaces: Pettit Protect High Build Epoxy Primer 4700/4701 may be applied over existing two part epoxy finishes, provided they are in sound condition. Brush-off sandblasting or very heavy sanding with 60 grit sandpaper is required to maintain maximum adhesion. Then apply three coats* 4700/4701 per instructions. Remember, coating performance is only as good as the surface to which it's applied. All existing two package epoxy finishes in poor condition, as well as one package primers and bottom paints, should be removed completely and the appropriate bare system as described above should be followed before using Pettit Protect High Build Epoxy Primer 4700/4701.
*Total dry film thickness is more important than the actual number of coats applied. On metal and fiberglass, if 12 mils total DFT is not achieved with three coats, additional coats are recommended until 12 mils total DFT is achieved.
