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.

Petit Epoxy Barrier Coat

a year ago

How do you review a paint you hope you will never see again? I had previously applied several coats of this paint to our 38 sailboats when we had the bottom blasted and prepped for a bottom job. The paint goes on easily and flawlessly without much fuss. Although the bottom preparation is the key to a successful application. I highly recommend this paint as a barrier and impenetrable coating prior to applying your choice of antifouling bottom paint.

Does not yeild a smooth finish.

6 years ago

Paint DOES NOT make a smooth finish once dried! Will have to sand to smooth out before applying bottom paint! will not level out no matter how thick applied. Leaves brush stroke lines. Although not smooth the paint is very thick and yields a very thick layer in just two coats if applied by brush. Must work quickly and carry a lot of paint on your brush. MUST keep a wet edge. Once applied must move on. Paint small strips going length ways on the boat until it is covered. If you see a run or try to smooth out a rough spot once it starts to dry it will only make it worse, paint is very thick and will glob up. Tired to roll and tip but paint dries to fast and tipping only makes it more rough. Sanding required to get smooth surface. If you are looking for a super high build product and aren't worried about rough surface this product is for you. If you are looking for a very smooth surface without sanding find something else.

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.

Q: I'm building plywood epoxy skiff that will have 10 oz cloth over outside and inside the hull. I could add a thickened coat of epoxy to fill the weave. Would the High Build epoxy primer do the same with multiple coats and sanded fair?

a year ago

1 Answer

A: It won't be as thick as the thickened epoxy so it won't fill as much but it gives you the advantage of extended recoat times without sanding so you lay on extra coats more easily.

Q: Bottom is painted with hydrocoat currently. When touching up bare spots or chipped/pealing areas after sanding , adhesion is poor when water blasting at haul out. Would it be advisable to use the epoxy primer on those spots/area where adhesion is an issue and if so, is there any issues with compatibility to areas around the spots that are hydrocoated?

a year ago

2 Answers

A: You can prime the bare spots but it will be difficult as you can't put the primer over the surrounding paint and it will look like it has been patched. You could clean the bare spots with acetone, sand the substrate with 80 grit, and apply the paint directly. This will allow you to feather the paint so it looks less patchy. The paint will adhere well to the gelcoat but the drawback to this method is that it will make your boat more susceptible to blistering and you will likely have to repeat this annually as more sections of paint lose adhesion. If the amount of paint peeling is substantial, it's likely the bottom was not prepped properly and your best option would be to strip the paint off, clean the bottom with acetone or dewaxer, sand well with 80 grit, then barrier coat the entire bottom before repainting. It may sound like a lot of work but it's not nearly as difficult as repairing gelcoat blisters later.

A: Yes, the 4700/4701 system is a barrier coat/primer system. It's very thick (like mud) and sticks to anything very tightly. I used a Teflon paint pan, thinking that I could simply peal the Pettit Protect off when it had dried and then re-use the pan - but the Pettit Protect stuck to the Teflon!

Q: Boat yard indicates that they do not recommend Pettit Epoxy Barrier Coat on a Boat that has been in seawater for any length of time because the Gel Coat and the Fiberglass becomes saturated with water. They indicate that the moisture will push the coating off of the gelcoat. They are saying that it is appropriate for new boats where the gelcoat and fiberglass are not already saturated with water. What are your thoughts on this?

6 years ago

9 Answers

A: Barrier coating a new boat is definitely a better position to be in than barrier coating an old boat, but not everyone can run out and get a new one. There may already be water in the old gelcoat and fiberglass, but if you have the hull taken back, allow it to dry for at least a few days or ideally a couple of weeks before applying a barrier coat primer. for the most part, the damage may already be done for some, but it may be the case where you can prevent further water intrusion if you can barrier coat it now.
