Product Details

TotalBoat Penetrating Epoxy is a low-viscosity wood rot restoration and repair solution that seals deeper & cures stronger than industry-leading penetrating epoxies. It has no VOCs, no odor & is 100% waterproof once cured.

This 2:1 system is ideal for restoring rotten or damaged wood, or sealing new wood for lasting protection against humidity, salt, mold & mildew. It works by gluing cellulose (wood) fibers back together, sealing a bare, porous wood surface from the inside out. Double the penetrating power by mixing acetone with the epoxy resin solution in equal volume. Easy to apply by brush, roller, or inject via syringe. Surfaces may be painted or varnished after light sanding.

Choose from Traditional (65-90 F) or Cold Weather (40-65 F) formulas in Pint, Quart, 1/2 Gallon, Gallon, & 3-Gallon kits.

Info & Guides

NO VOCS, NO SMELL.

Cleanup is easy. Wear latex gloves, wash off with soap and water. No solvents required.


APPLICATION NOTE: The wood must be bare and unfinished. Also, TotalBoat Penetrating Epoxy will not penetrate and level well when applied over some stains. Always test an area first. DO NOT USE on top of Minwax oil-based stains.


TotalBoat Cold Weather Penetrating Epoxy is perfect for use during the colder seasons. Compared to our traditional TotalBoat Penetrating Epoxy, our Cold Weather formula offers similar performance characteristics, but cures completely and reliably in cooler temperatures. Its tack-free properties also allow you to sand sooner.

WARNING: TotalBoat Cold Weather Penetrating Epoxy should not be used as a fast-cure epoxy in warmer temperature conditions because doing so can be unsafe and result in premature exotherm, brittleness, and improper curing.

Application Temperature Ranges:

  • Traditional formula - 65-90°F
  • Cold Weather formula - 40-65°F

Disappointed

8 years ago
Not recommended. Sat on oars like heavy varnish. Not much penetration. Probably should have thinned. Working pot life right at 15 minutes. Then smoke, heat and too hot to hold container. Very little penetration on sanded ash. Will have to sand and use varnish for final coat. Go with CPES from The Rot Doctor.

Not exactly equivalent to Smith's CPES

8 years ago
Product may perform perfectly well in some situations, however it has a short pot life in larger batches compared to Smith's CPES. We used this to saturate a still beam after removing surface rot. The pot life was shorter than CPES and it did not seem to penetrate as well. We lost quite a lot of the product in the pot before we could get it on to the wood. while the Total boat may be fine for pre treating wood, I would not give it a strong recommendation for rot treatment when high penetration into the wood is desired

This is a terrific product - odorless and VERY easy to use.

This resin is very thin, like water, and I inject it into wood which has lost its structure due to termites, dry rot, etc. It saturates quickly, and cures overnight, creating an ideal base for applying thickened epoxy wherever voids need to be filled. The thickened epoxy cannot be absorbed into wood, and therefore no shrinkage occurs (surface remains flush).

Works as advertised

8 years ago
I used it as directed, mixed 2:1 and not thinned, on a transom I fabricated for a 14' aluminum boat. I prepped the birch plywood by sanding to 100 grit. Expecting good penetration and coverage, and not overly concerned with aesthetics, I did not bother to fill minor chips or dents. The epoxy produces a hard, flexible surface that is verifiably thick to the naked eye, and it seems to soak and plaster every bit of the wood, just as I wanted it to. It has little odor (even pleasant) and mixes and brushes very nicely. I applied the product at about 70'F (after warming the jugs in hot water for 15 mins) with some humidity. The first coat, which was applied too thickly, took about 48 hours to cure; the second thinner coat took about 24 hours. I will apply at least one more coat, and then will lightly sand and apply a marine-grade paint for UV protection. I did not intend an aesthetically pleasing clear coat, so the product is perfect for my needs. A woodworker wanting a pure clear varnish-type finish might find this leaves some bubbles and drips, or may have more talent and time than I to render a fine finish. To me, as a clear coat, it is not overly aesthetically pleasing, being kind of ""syrupy"" and heavy. However, one uses epoxy for its protection first, and this suits my needs ideally.

I tried to order CPES and this product turned up in the search. I figured that I would give it a try. It is too thick to penetrate, even when I thinned it by 50% with acetone as recommended in the instructions. The product sits on top and has very little penetration. The CPES works much better, and I will find a new source to purchase that product. CPES gives excellent penetration and stabilizes the wood.

Used product on white oak tiller I was refinishing. Instructions were a little inadequate. After using product, Off Center Harbor posted video on using and finishing penetrating epoxy. Wish I'd seen it before using product. Emphasis on applying epoxy very carefully to avoid unevenness leading to unnecessary sanding would have been helpful. Had called Jamestown and been advised to use chip brush. Wish I'd rolled and tipped per OCH. Overall, however, I'm still pleased with product and results.

i used this product to seal the replacement stringers & flooring on a Bayliner floor replacement & also to ""beef up"" a soft spot in the transom area. This product does everything it claims. I was amazed at the penetration in the transom area & the end results were amazing. Just a couple tips...be sure to mix well for at least the recommended two minutes, preferably three. Doing this will give you consistent results between batches. Also, watch the clock! You have between 20 & 25 minutes pot time, so plan ahead. Again, great product that yields great results.

Not just for boats

Used on under side of kitchen cabinet around sink and dishwasher to keep dampness from swelling wood. New istalation, so it will be years before I know if it was effective. The fact that it penitrates the wood vs. Just coating it was why I decided to try this product. It remains tacky for more than 24 hrs at 70 F. This slows the project.

Works like a charm

After having gallons of experience using Smith's on our 56 Sea Skiff and on our 53 rotted windowsills at home, I thought I'd test your product on this bathroom repair. I could have just replaced the plywood but the punked ply went underneath the tub and past the wall studs; inaccessible without demolition. PE got to places my tools could not and now the floor is hard as a rock. Didn't want to wear my mask in the heat of August in a small bathroom. What a joy to just open the windows and use your product.

Is It Epoxy or Really Hard Varnish

I watched JD's video a copule of times to insure I didn't miss any steps. I applied it to wood trim on an '88 Whaler Outrage. It goes on like a very thick varnish. Allow at least 12 hours before doing anything to it, or with the boat. So far so good, although I won't know until next Spring whether it performs as advertised.

I was looking for a product that I could coat my new marine plywood to replace the rotted flooring in my alumacraft boat .

WOW ,thank you Jamestown Ditributors for delivering such a great product . Due to the cold weather in Upstate NY ,there is just no way I could have done this outside and with limited space in my garage there was no way I could use a product that had high VOC's . went on great and took a little over 2 days to dry completely but I am very pleased with the finish product .downfall it is not UV resistant ,but was just what I needed as I covered the finish top coat with carpet and I will have a flooring system that will last for years to come ,hands down , thanks a million.

Q: Once Totalboat Penetrating Epoxy is fully cured, will West System epoxy provide an adequate bond to the Totalboat repaired area. I intend to first use Totalboat Penetrating resin in a boat transom that has been drilled with 3/8 holes 1inch apart followed by injecting mayonnaise consistency thickened West System. I already have a large quantity of West System products. The transom has been drying for 16 months but a section will be cut open to verify conditions.

It is recommended that I fiberglass the concrete form tube to make it extra strong to withstand high speed and aerodymanic forces.

A: Penetrating epoxy is not suitable for laminating fiberglass. Take a look at TotalBoat High Performance epoxy or traditional 5:1 epoxy. Epoxy may not be suitable if portions of your lamination are going to be exposed to temperatures over 125 degrees. Xyla Foxlin is a YouTuber that uses TotalBoat.

A: If the rot is extensive the best option is to cut out the rotted sections and seal the exposed wood with penetrating epoxy. Then cut new pieces of wood to fit the cutouts and glue them in with thickened epoxy. That will give you a solid foundation to glass over.
