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

Both the cool weather and warm weather products were used with excellent results. With a few well placed holes drilled the epoxy penetrated deep into the wood fibers. I also had an opportunity to cut a cross section and was amazed how well the epoxy penetrated.

It's good stuff, but it must be exactly mixed or else you'll muck up your project. I prefer West System 655, which is a 1:1 ratio, and sets less than 24 hours, cures in about 2 days.

Works great

I got this kit to stabilize an Amboyna Burl guitar top. The top was beautiful and I wanted to keep as much of it intact for the finished piece. Just so happens that part of it was very soft, and if left untreated would have easily broken off. After painting on with a disposable brush, I allowed it to remain untouched for 3 days (overkill, I know). It came out perfectly. I was able to get the result I was looking for and am very happy. I don't believe I'll need to use it very often, but if and when this supply runs out, I will definitely purchase again.

A (maybe) unintended use that worked out well

2 years ago
I just completed a Greenland style kayak paddle out of Northern White Cedar. The only cedar that I could find that was knot-free was very porous, soft and prone to dents. After the final sanding I coated it with one coat of Total Boat Penetrating Epoxy thinned 75% with acetone, recoating the dry spots as necessary followed by a second coat thinned 30%, again recoating as necessary to level any low spots. Final coat full strength on tips & end grain. Wood now thoroughly sealed and much more durable. Allowed 72 hours before final sanding & 3 coats of water-based varnish. The penetrating epoxy significantly hardened the wood and made an excellent base / prep coat. In retrospect had this product been available when I built my strip-built kayak I would have used it as a prime/bonding coat before laying on the fiberglass.

Except for the hardener bottle being miss labeled the product seems to have worked well. The hardener bottle was labeled one quart when in fact it was two quarters as it was supposed to be for a proper 2 resin to 1 hardener mix ratio. Fortunately I mixed it that way and was correct. I verified that by pouring 2 quarts of water from a juice bottle into the hardener bottle.

A remarkable solution to a nasty problem!

The chipboard bottom of the compartment where city water connects to our 5th wheel became saturated when a hose gasket failed. Once dried out, I mixed the TotalBoat Penetrating Epoxy per the instructions; drilled a few 1/8"" holes in the wood and poured the epoxy down the same path the water took. It dried in a little over one day; is rock solid and more importantly, can't be damaged in the same way again. It worked better than advertised!

old boat restoration

2 years ago
I am restoring a 1954 Glen L. Witt outboard runabout. All wood construction. The deck is plywood and I took it down to bare wood. Then I used penetrating epoxy (thinned 50/50 with acetone) to firm up and prepare for varnish. The thinned epoxy penetrated deep into the plywood and the whole structure feels much stronger. I have now put on two coats of varnish (at least one more to come) and it looks fabulous.

Questions

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.

A: You can go over Totalboat Penetrating epoxy with West System. Make sure it is fully cured, wash with warm water and a scotchbrite pad, then sand with 220 grit.

Q: Can Total Boat Penetrating Epoxy be used with 30 year old pressure treated wood on the end grain of some 2 x 6 deck boards? This is by no means green wet with arsenic wood. I can get it pretty dry by picking out most of the rot and drying it with a heat gun. Would then wood fill end of boards and cap with the decorative 2 x 4cap. LET ME KNOW. Thanks

Q: Hello. I will be attempting a level 3 high power rocket certification launch in the next few months. It is recommended that I fiberglass the concrete form tube to make it extra strong to withstand high speed and aerodymanic forces. I have seem recommendations for using epoxy to go with the fiberglass. Some folks seem to use West, others recommend higher cost epoxies. Has anyone used your epoxies in rocketry? What did they use? Thanks in advance.

a year ago
1 Answer

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. She has done some stuff with rockets.

Q: Is there a video or written instructions on applying this product to rotten stringer/ bulkhead sections of boat about 6 to 8 inches in length with about 3 inches of the wood completely rotted out? I have not removed a section of fiberglass flooring yet to have better access and to be able to work exclusively on the section in question. Thanks for your feedback.

a year ago
2 Answers

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.

Q: what is the recommended moisture content of the wood to be treated? What about thinning - denatured alcohol vs. acetone?

a year ago
2 Answers

A: Thank you for reaching out. Either thinner works well. For moisture percent: The maximum wood moisture content that TotalBoat Penetrating Epoxy can be applied varies depending whether it is being thinned or not. Unthinned Penetrating Epoxy should not be applied to wood with a moisture content greater than 10-12%. Penetrating Epoxy that has been thinned (to the maximum percentage) with acetone or denatured alcohol can be applied to wood that has a maximum moisture content of 20%. In every application, to promote the best results, it is strongly recommended to dry the wood as much as possible prior to applying Penetrating Epoxy.
