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.

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.

Unique specific purpose
10 years ago
I plan to use this on the cabinet bottom under a sink to provide a water resistant coating to the particleboard. Previous leaks have warped the board which has been leveled with floor leveling compound. The small container allows me to have enough to cover without the waste of extra coating left over. I had to look hard for this epoxy and container size.

This is a good high build epoxy primer. Goes on well and covers great. Also seems to sand well. Should seal and hold up well, have not water tested yet, but looking forward. Good price also.

I would buy this product again and again
16 years ago
It works very well if applied following the directions of the manufacture. I used it on the stern board of my old Zociac, to provide a water barrier. I know it would be good as a primer for under water metal parts. I mixed some of the primer with a putty knife. It dried on the knife and I had the devil of a time trying to get it off!

Q: null 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?
11 months ago1 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: null 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 ago2 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.

Q: null HI, I purchased the 4700 kit, I haven't opened the can yet, Is it all ready mixed together and just need to stir it and wait 15 minutes to hit..? I thought I had asked when purchasing but forget.. I just open it stir and use it? Just put the lid back while painting.. And then use the anti fouling right after , at lease one coat. Correct?
4 years ago5 Answers
A: I simply mixed the two components together using a drill-powered paint stirrer. If I recall correctly, some of the solids in the paint had settled in the can due to it sitting in my garage for several months before use. -Andy

Q: null Are there instructions for mixing batches smaller than a quart?
5 years ago2 Answers
A: Yes, there are instructions on the can, the mixing ratio is 3 parts of component A to 1 part of component B, and only mix what you are going to use. Instructions say at least three coats, I apply five thin coats with a 3/8 roller. Instructions include drying time and pot time for the paint. Make sure you read and understand the instructions before you start.

Q: null 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 ago9 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.
