TotalBoat 2 Part Epoxy Primers

TotalBoat Epoxy Primers provide excellent finish adhesion & corrosion protection on fiberglass, steel, wood & aluminum. Surfacing Primer is ideal for surfaces that are ready to be topcoated. It ensures adequate filling & lets you build up to 12 mils wet in 3 hrs. High Build Primer has a denser formula to fill pinholes & small surface defects without extensive fairing or applying a surfacing primer over it. Both primers have a simple 1:1 mix ratio, easy application by brush, roller or spray, fast dry times, optimal sanding qualities & can be overcoated with 1- or 2-part urethane coatings.

Primers are available in Gray & Off White. Quart Kits include 1 Qt Base & 1 Qt Activator. Gallon Kits include 1 Gal Base & 1 Gal Activator.

Bonus: Each order includes 2 mixing pots, 2 10in stir sticks, 2 2in foam brushes, 2 paint strainers & 1 pr. lg. latex gloves.

Surface Prep Cleaner/Reducer/Thinner

  • TotalBoat 2-Part Epoxy Primer Reducer


TotalBoat 2-Part Epoxy Primers are for marine use prior to the application of a topcoat. Their VOC levels of <420 g/L (Surfacing Primer, admixed) and <350 g/L (High Build Primer, admixed) meet all current guidelines.

Also available is a 2-Part Epoxy Primer Reducer (sold separately) formulated to extend wet film flow, especially when applying primer through a spray nozzle. This reducer can also be used as a surface prep cleaner, and as a solvent for cleaning equipment.

Surface Preparation

Fiberglass/wood: Abrade with 100-150 grit sandpaper.
Steel: Sandblast or grind to SSPC-6 Commercial Blast. For improved adhesion, apply TotalBoat Strontium Chromate Epoxy Primer directly prior to application.
Aluminum: Sandblast, grind, or sand the surface with 100-150 grit sandpaper, then use TotalBoat Aluminum Boat Etch Wash as directed. Dry the surface completely and apply TotalBoat 2-Part Epoxy Primer within a maximum of 4 hours.
Previously Primed or Painted Surfaces: If no corrosion byproducts are present, abrade the surface with 100-150 grit sandpaper to remove gloss. Wipe away any surface contamination with a lint-free rag wetted with TotalBoat 2-Part Epoxy Primer Reducer. Follow with a clean-dry, lint-free rag to ensure no contaminants were spread or left behind.


Shake or stir the primer base well such that no material is settled on the bottom or sides of the can. Mix 1 part primer base with one part primer activator by volume. Allow an induction period of approximately 30 minutes prior to reduction and application. See Epoxy Primer Reducer Data (below) for details on thinning the product, if desired.


Spray Application: SURFACING PRIMER: After induction period, reduce 20-30% with TotalBoat 2-Part Epoxy Primer Reducer for desired application and film thickness control. Coats can be applied at 3-4 wet mils building up to 12 wet mils thick, waiting 1-3 hours between coats. For single-coat application (3-4 wet mils). it can be sanded after 4 hours. HIGH BUILD PRIMER: After the induction period, for desired application and film thickness control, reduce 25-35% with TotalBoat 2-Part Epoxy Primer Reducer. Apply with a 1.8-2mm spray tip. Coats can be applied at 3-4 mils wet each, building up to 20 wet mils thick, waiting 1-3 hours between coats. For single-coat application (3-4 mils wet), it can be sanded after 4 hours.

Roll/Brushing Application: Thinning should not be needed, but if reduction is desired for flow, use TotalBoat 2-Part Epoxy Primer Reducer. If rolling, use only 1/8-inch nap epoxy/solvent-safe foam rollers. Subsequent coats can be applied every 1-3 hours, up to 12 wet mils thick (Surfacing Primer) or 20 wet mils thick (High Build Primer).


For multiple-coat application, after the final coat, allow 16 hours to cure before sanding. If possible, do not wait more than 24 hours to sand, especially with only one or two coats, as the primer will get increasingly harder. Use 220-grit or finer sandpaper for optimum topcoat appearance.


Use with adequate ventilation and proper respiratory protection. See SDS for complete details of composition and precautions.

Warning: Do not apply paint materials to surfaces less than 5°F above dew point, or to surfaces warmer than 125°F. Ambient air and surface temperatures should be above 45°F and below 125°F.

The best fiberglass product ever.


Covers my wood boat better than any other product. Easy on, smooth and dries hard. After mixing let it sit for 30 min. then brush on with a foam brush. Just wish it came in white.

Base was cemented to the bottom of the can


It seems like a good product once you get it on but it was very difficult to mix the base. I first opened it and tried to stir it up with one of the included stir sticks. That didn't work at all so I took it to a local paint store where I buy my other supplies and had them run it on their paint shaker mixer. That worked a little but not much so I had them run it again. Not much improvement. I finally bought a paint mixer for an electric drill and mixed it that way for about 30-40 minutes. There was still some stuff stuck in the corner but I decided it would have to be good enough. I did let the product sit for about 2 months between buying it and using it but with the stated 2 year shelf life I don't think it should have been that difficult to mix. I rolled it on with a foam roller outside at the boat yard. It went on smooth and I received several complements on how nice it looked. I mixed up 2 liters of it and by the time I was getting to the bottom it was starting to get a little sticky. This was about 1-2 hours after the induction time ended. Maybe I needed to add more thinner to compensate for the solvent that evaporated during my mixing of the base component. If I had to do it over again I would choose a different product just to try and avoid all the time I wasted trying to mix this when I could have been painting.

Great Primer for water protection


I have been restoring an old wooden sailboat, and have applied a lot of penetrating epoxy to the inside planks, frames, and ribs. After it all was sanded, and cleaned, then I applied this 2-part Epoxy Primer. It allowed me to apply 2 uniform coats within a single day because the drying time was from 1 to 3 hrs. I used the Quart size, and mixed half for the first coat. Also I thinned the paint with the Epoxy Reducer. This quantity was the exact amount that I needed for the first coat. I waited 2 hrs, then mixed and applied the other half (also with some reducer added). This 2nd coat looks great, even though it's just primer. Also, because it's epoxy, it will give me some extra waterproofing to the inside of the boat. It was easy to apply with a brush and roller, but it does stink. So, I highly recommend that a respirator be used, and have good ventilation in your paint room.

My first experience with two part primer


Base came in nice condition was not hard to mix it but accelerator can had a small hole at the top.I'm happy with result so far.


San Diego


Difficult to mix


the base is next to impossible to mix settled material. Suggest that the base component be thoroughly shaken by Jamestown prior to shipping to make it easier for end user to properly mix.


Seaford, VA


Good product


First batch I received must have been old. The base was stuck to the bottom of the can and would not mix back up. The activator also had a hole in the top of the can from shipping with the shipping clips installed.




I would not purchase again.


Base was impossible to mix back to usable state. The activator came with holes punched in top of can, and leaking out.
