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

Great product for wood projects that will be outside

11 months ago
Very easy to mix up a batch and apply to Red Cedar lumber. I'm applying it to the lumber I will be building a deck with. So far all the projects I've built for outside I have applied this epoxy too and they keep the same look through out the year. No fading, nothing.

Red Oak patio table

a year ago
Made a patio table from 6/4 red oak for a family member and wanted it to be able to stay outdoors year round. A friend told me about TOTAL BOAT penetrating epoxy. After discussing the application with total boat tech support, they were extremely helpful guiding me on proper wood prep application, preparing between coats and the need to apply a spar varnish (Goeam 2.0) for best UV protection. I applied 2 coats of penetrating epoxy and 3 coats of varnish. The table is finished but, still in my shop awaiting delivery to RI. I am extremely please with the results so far and can't wait to see how it performs in its final home. Total bolt folks are the best and extremely easy to work with and go the extra mile to provide a first time user with all the tricks and details to get the job done right. I will be a routine customer and will recommend total boat to my friends and fellow woodworkers.

I would but this product again

a year ago
I'm on the coast of SC facing almost due south and my wooden handrails get a ton of hot sunlight & I'm having trouble getting latex paint to last. So I'm trying an epoxy treatment to see if the epoxy can better stabilize the wood & reduce the expansion & contraction. I only recently read that this epoxy was not well suited for treated lumber but because it was KDAT lumber & it's aged for more than 3 years, I hopeful the epoxy will fully adhere & hold up as a base. We'll see. The epoxy went on as expected & 2 coats gave me the finish I was looking for as a base coat under primer & paint.

I am dismantling and reassembling and 1959 Century runabout. As the pieces are cleaned and prepped they receive a coat of Total Boat CEPS. As we have progressed to the staining and varnishing of the craft. I have used CEPS as a sealer. (The CEPS does yield a darker tone than traditional sealer, and I would not recommend it, CEPS, for a sealer on blond or Avodire surfaces.)

Expensive but worth it

This penetrating epoxy made a potentially large project very small. Not a boat application, I used it with the resin cut with acetone to deep penetrate rotted rafter sections. It took 3 applications and 2 days of curing to get the punky wood solid again to where it would hold screws. But it worked. Wood that felt like styrofoam now feels like Doug fir again.

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: 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.

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.
