Product Details

TotalBoat FlexEpox is a tough, 2-part flexible epoxy adhesive used to create permanent structural bonds that dynamically absorb stresses from contraction, expansion, shock, & vibration, and bend without breaking. Use on fiberglass, metal, plastic, and wood—even hard-to-glue, oily domestic and tropical hardwoods. Great for repairing aluminum boats, too.

Simple 1:1 mix ratio, 75-minute working time, & fast cure time make it easy to use and ideal for quick repairs. Also for creating small laminated parts subject to a lot of flexing.

FlexEpox works in a wide temperature range, from 40 to 125°F, and can be applied to damp surfaces. It can even cure underwater. Pair with TotalBoat fillers to suit your application.

Available in an 8 oz. kit and a 32 oz. kit.

Info & Guides
Compare to two-part West System G/Flex 650. TotalBoat FlexEpox maintains its form and properties better at higher temperatures, and is a better value. It also has higher flex tolerances and lasts longer than flexible, one-part urethane adhesives and sealants.

Flexible and strong
By JimBOB from Georgetown TX

Verified Purchase

I used this to glue a bulkhead in my canoe. Was very easy to use, the graduated measuring/mixing containers are a great idea. I mixed with cobosil and nylon fibers to make a runny paste and used the included popsicle stick to make a perfect fillet along the joint. The longer cure time let me fiddle with it until I was satisfied with the the results

Bottom Line Yes, I would recommend to a friend

I would buy the flexible epoxy again
By Kamil from Racine

Verified Purchase

I had to fair around the keel joint of my Mariner 36 sloop. I used 2 sets of the product to first paint it on and then mixed it with the total boat silica thickener so it wouldn't run down the keel.One can probably sand it but I used I grinder to smooth it out. Painted Interlux 2000 a 3 coats over it all, eventhough I didn't have to, but I had the paint from another job. Applied Spartan anti foul paint x 2. Done.

Bottom Line Yes, I would recommend to a friend

My Go To Epoxy
By SteveVT from Vermont

I have used this on several products, including end grain cutting boards. Glue up is easy and can be done in thin layers with a putty knife. I've also done furniture and the joints hold up well. Mixes well with fillers. While the 1:1 mixing is fairly simple for small repairs, it is hard to meter out in the 1-2 ounce quantity, as others have pointed out. It would be great if JD could supply a small cylindrical marked measuring cup so we could be more exact on this stuff. I think this stuff is too thick for pumps.

Bottom Line Yes, I would recommend to a friend

This is what I needed to fix my boat
By JoeD from Hollister, California

Verified Purchase

It took quite a bit of research to find this product. I'm from RI,now living in California, with my old '88 aluminum 17 ft run about. This flex epoxy worked great for gluing my new plywood transom pieces together. I even used it to seal some pin holes inthe inboard aluminum panel that was corroded.

Bottom Line Yes, I would recommend to a friend
