Product Details

Pettit Protect High Build Epoxy Primer 4700/4701 is a heavy-duty, two-part epoxy-polyamide coating that may be used on metal and fiberglass for maximum resistance to water. This versatile primer is excellent for not only osmotic blister repair and prevention, but can also protect underwater metals from corrosion. Use with Pettit Vivid bottom paint for additional chemical resistance.

Pettit Protect epoxy primer forms a tight, high build, durable film. The complete coating system is resistant to water, many industrial chemical fumes, and very humid environments. It is ideally suited to many commercial and pleasure craft applications and has excellent durability in exterior exposures. Keep in mind that, like most epoxies, it will chalk if not top-coated.

Pot life ranges 2.5 - 10 hours based on ambient temperature. At least 2 coats are required, with a 3rd coat recommended for best results. Apply using brush, roller, or spray.

APPLICATION INFORMATION

Stir both components thoroughly. Mix the two components together in the ratio of 3 parts of Component A to 1 part of Component B by volume. Allow to stand 15 minutes at approximately 70 degrees before using. (Allow to stand at least 30 minutes if temperature is between 50 degrees and 65 degrees F.) Primer may be applied by brush, roller, conventional or airless spray. Thinning is not normally required for brush or roller application, however, small amounts of 97 Epoxy Thinner may be used if necessary to facilitate application. For spraying, use 97 Epoxy Thinner at levels of 5-10 percent by volume to ensure a smooth finish with minimal orange peel. Wet film thickness should be 7.1 mils per coat, which yields 4 mils dry film thickness. A wet film thickness gauge should be used to monitor paint application. Total dry film thickness for a three coat application should be 12 mils minimum for maximum coating performance. If this has not been achieved with three coats, additional coats are recommended until 12 dry mils is reached.

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.
Bare Fiberglass: All fiberglass surfaces, regardless of age, should be 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 Specification for detailed instructions.
Bare Steel: Sandblast to SSPC-SP 6 Commerical 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.
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.
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 1/2 - 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 of 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.

May very well do the job (barrier) but will not yeild a smooth finish like other products we have used. Try as we may, several types rollers and tipping, did not result in a suitable finish over which to paint for a smooth bottom job. Very hard sanding as well so be careful what you put this on.
