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 10 in stir sticks, 2 2 in foam brushes, and 2 paint strainers.

Surface Prep Cleaner/Reducer/Thinner

  • TotalBoat Epoxy Primer Thinner 200


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.

The recommended thinner is TotalBoat Epoxy Primer Thinner 200 (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. Solvent wipe with TotalBoat Epoxy Primer Thinner 200 to remove surface contaminants. Follow with a dry, clean, lint-free cotton rag, and allow to dry completely.
Steel: Sandblast or grind to SSPC-6 Commercial Blast. Remove residue with a vacuum or air hose, solvent wipe with TotalBoat Epoxy Primer Thinner 200, and allow the surface to dry completely.
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: Ensure that the substrate is a 2-component system. 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 Epoxy Primer Thinner 200. 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 Thinner 200 data (below) for details on thinning the product, if desired.


Spray Application: SURFACING PRIMER: After induction period, reduce 15-25% with TotalBoat Epoxy Primer Thinner 200 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 15-25% with TotalBoat Epoxy Primer Thinner 200. 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 Epoxy Primer Thinner 200. 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.

This set my project back a week. It claims to be brushable, it came out like driftwood grain. I had to sand all of it off. It did not sand well. I bought interlux primer when I finished stepping off the total boat primer

Seems Like a Good Product


Product went on easily and cured to a strong finish. I mixed the whole kit at once and had more than I needed. I haven't not finished painting yet - so I can't say how well the paint will adhere. The primer sanded up nicely, so I think it'll be ok.




Almost impossible to mess up


Used as a sealer on transom after fairing and primer filler sprayed 3 coats an hour and a half apart blocked with 400 the next day and sprayed with awlgrip 2000 looks beautiful

Leaves a fine finish.


I use the high build primer on a regular basis. The trick that works for us is to roll on a thin tack coat and then come back a few min later with the build coat. Sands reallly well. It can be tough to mix. Home Depot sells a small paddle wheel mixer in the drywall department that works great. I cut the mixer's shaft down a little bit to make it easier to handle.

Shipped with incorrect thinner


I've yet to use the primer but had the local Lowe's shake the can before opening it to help alleviate mixing concerns.BIG Caution - be sure you read and select the correct thinner; the package came all neatly bundled but included the WRONG THINNER. Customer service sent me the correct quart aptly named "2-Part Epoxy Primer Reducer"The 5 star rating is presently for the great customer service/tech advisor's response.

I would buy this primer again


I would not wait the 20 minutes ,it starts kicking off right away.

Great Stuff - Tough as Iron!


Used two 1 quart kits to prime the outside hull of my 1955 Layman runabout. I sed the "High Build" primer on the topsides - the kit gave me two coats and the surfacing primer on the underwater part of the hull - the kit gave me enough for a single coat.I chose the "High Build" where the hull would be seen. Lots of sanding and filler made for a fairly smooth surface. The wood in the underwater part of the hull was in better condition - it had a lot more paint on it than the topsides. The surfacing primer filled the smaller nicks and left a glossy surface, which I will have to cut prior to painting in the spring.One thing about both primers. Once they cured, they were hard as nails. The small drips of the "High Build", which I had applied while the hull was rightsize up, were really tough to remove. I can't imagine what this stuff is going to be like come springtime.TotalBoat products is all that I will use on this renovation. Next spring, the two part wet edge topside paint.

Great Stuff - Tough as Nails!


Finished stripping and priming the hull of my '55 Lyman runabout. I used the TotalBoat 2 part "High Build" primer on the topsides and the TotalBoat 2 part "surfacing" primer on the underwater section of the hull. The entire hull was faired with TotalBoat fairing compound before hand.As you can see from the attached picture, the topsides had an off white color while the bottom was bright white. No big deal since I will finish with a urethane paint in the spring. Both primers were fairly easy to apply but required thinning often to allow easy flowability. Sanding of the "High Build" primer was tough! The primer had cured for a few weeks and let me tell you, 80 grit paper didn't make a dent in it.The project was well worth the time and effort. The hull belies the fact that it is over 60 years old.

Tough Stuff!!!


This is an addendum to my previous comment about the application of the high-build primer to the topsides of my vintage Lyman runabout. I have finished scraping the bottom of the flipped hull. While scraping the edges of the strakes, I found that the primer that had been painted on the edge of the last strake was near impossible to remove. It appeared to be unaffected by heat from a heat gun, scraping with an "All Purpose" tool and even scraping with a carbide blade scraper. This stuff is like iron (maybe better)!!!Next step, priming the bottom of the hull. This time I'm gonna use the surfacing primer. We shall see!.

Great Stuff!!!


After watching Lou S on "Tips from a Shipright" using the Total Boat 2 part epoxy primer, I tried it on the topside hull of a 15ft Lyman runabout that I am restoring.Out of the can, the 2 parts are very stiff and there is a lot of "Solids" on the bottom of the cans. As Lou had recommended, I used a 1x1 to stir-up the solids - the flimsy paint stirrers would have broken.Took my time and insured that both liquids were well stirred and then stirred some more when I combined them. After waiting the requisite 30 minute "Induction" period, stirred in just a little 2 part epoxy thinner and then applied using a 2" chip brush. The coating went on easy and covered well. It cured overnight and I then saved down with 150 grit paper by hand. Also, I prepared the hull surface by hand sanding with 120 grit paper.I used Total Boat epoxy fairing compound to fill the dings and divets. then applied a second coat of primer. I am very happy with the results and the quart kit (actually 1 quart each of the base and hardener was more than enough for the unwetted portion of the runabout's hull (from the gunnel down 5 strakes).I will need another "Quart" kit when I flip the hull and do the bottom. But, I intend to treat the entire bottom with Total Boat penetrating epoxy first. So, I should not need more that the "Quart" kit.Again great stuff!!
