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. BONUS: Each kit includes 2 16 oz. mixing pots, 2 stir sticks, and a pair of latex gloves.

what is the shelf life when sealed in the original container, in a 40 to 90 degree shop in 20 to 40% humidity
Shelf life is well over a year, no specific limit.
The product description says can be used to "create small laminated parts subject to alot of flexing" . Can I use this product over two layers kevlar tape to create a "hinge" that has some range of motion? Once it dries, is it flexible but not sticky to the touch? Thx
This is pretty thick and may not wet out kevlar. It's flexible as far as epoxies go but motion would be limited.

can you paint over with topside paint
You could paint over this, sand with 80 grit first, then prime and paint.

I have been looking for spar epoxy. And i Will Cruise in the tropics. Been consithering to use flex 650 and west blend. West systems does not have good strength at higher temps.Read: at predicted painted or varnished surfaces it has lost strength. I believe I need softer epoxy due to wood (spar) movements due to load and moisture.I could not find any data about flexepoxy strength at high temp (160F for example). Did not see either breakdown (Tg ) temp. The temperature to break the epoxy glue for repair.What are your higher temp data?Any recomandation of flexepoxy mixes for bird mouth spars.
Sorry, we don't have any information on strength at high temperatures, it would be similar to West System 650

Can FlexEpox be used to adhere wood strips to the fiberglass substrate of a cockpit sole? The wood I intend to use is Red Balau. The sole currently has a non-skid finish, which would be sanded down for improved bonding.
Yes, sanded down the wood strips should not have holding issues. Keep inmind, epoxy does not hold up well (long term) outside, under *direct* UVconditions. D Jacobson
I think it would perform just fine in that application. I would just be sure to give both surfaces a sanding & wipe down with acetone prior to glueing.
Total Boat Epoxy has been a very good product when I have used it. I wouldbe willing to bet you could but I have never used it on Red Balau so I couldnot say for sure?? But I think so. I have not used it yet where itfailed?? Best of luck
I have done that with my FlexEpox but I can't see why it wouldn't work, I have patched things on boats, cracked plastic bathtubs and fixed punctures in aluminum boats, use it as a finish coat after wrap a fishing rod guide with no failures. If everything is flat and the bonding surfaces will uniformly touch should work just fine but be aware this product is pretty thin unless you use a thickener. If the wood is free from oil and clean I would put a coat on the wood then on the cockpit sole.There is also some epoxy that premixes as it comes out of the tube (like a caulk gun) that might be a better product since the epoxy comes out more like caulk which in my mind might be better for what you are doing.
Could this be used to seal leaky seams on a wooden boat?
Yes, I think it would be fine. Be sure the wood is fully dry. A lot dependsupon the specific problem. If the boat tightens up with a good soaking,that is a different problem than a boat with open seams. Every situation isdifferent.If there are open seams, I would add something like WEST System 403Microfibers Adhesive Filler to enhance the gap filling properties. I lovethese flexible epoxies. If you are just hoping to avoid a soaking period,you would probably have to add a full fiberglass layer with theaccompanying weight addition.
Yes, you could.

Can this product be tinted using Mixol black tint?
Not really. Once mixed it is a dark brown. It dries to a amber'ish brown.Cheers from my iPhone
You can sand it and stain it, but I don't know about mixing anything with it. Might water it down and weaken it.
This epoxy can be tinted, we offer epoxy colorants that are compatible, but it is up to the user to always test any additives or colorants for compatibility and decide whether it meets their needs. We always recommend testing before attempting to use it on the final project.

Replacing a rotted transom on a PVC inflatable. Can the be used to re-glue a new plywood transom in place?
Sorry, I don't have any experience with that application. FlexEpox is not completely flexible. It just has a little more "give" than traditional epoxy.
I have made similar repairs on a PVC inflatable in the past. The transomseparated from the side tubes. I used 3M's 5200 to glue/attach them.Worked well for several more years. As far as coating/protecting new woodin a transom, I have used West System epoxy coating products as they havedetailed on-line preparation instructions. I would not use any epoxyproduct for attaching wood to PVC, as the epoxy would not be flexibleenough or UV protected enough to hold over time. 3M's 5200 is a betterpick... It stays flexible and attaches well to PVC and although even 3M's5200 will eventually breakdown due to UV... it will perform well for manyyears. Total boat epoxy products are more than likely acceptable for woodcoating protection and I have no opinion on these products as I have usedTotal Boat products on small repairs only - It's just I have far moreexperience with West System products.
This product should actually do okay for bonding the wood and PVC. The PVC would need to be treated first for an optimal bond, (for some cases we would recommend a flame treat, but this may not be safe to perform in your case). It does have the flex factor that allows the PVC to still be flexible as well, and we have had a number of customers use this product for similar applications. For any specific questions you have regarding this, please call one of our techs at (800) 497-0010.

will this seal a leaking hot tub PVC manifold that has four flexible PVC hoses in it.Does it work on flexible PVC. if I build a form around it and pour it in
I am inclined to doubt it. My experience with leaking PVC plumbing has led me to the process of removal of any damaged or questionable components and replacement with new fittings and line. I am not sure what your pump pressure is, but my attempts to repair leaks instead of replacing leaky parts has ALWAYS resulted in continued leaks. Not sure what the cause of your leak is, is this over-winter freeze damage? Or system age? If you have adequate access to work on cutting out the bad components and building a new manifold, that will probably be less frustrating in the long run. What would your plan "B" be if it still leaked, would a block of resin further complicate replacement of the manifold? Maybe someone else has tried this with more success. Good luck!
I can't help. I used it to install additional wood bracing slats on theunderside of a fiberglass hatch and it worked very well for that.
A PVC manifold should probably be replaced, this product is not recommended for your application.

I would buy this product again
I used a small amount one time and like its extended working time. I will use it more as the project progresses
North Augusta SC
Used it to glue fancy border of parquet flooring to plywood. Honey-like consistency easy to work with. Decent pot life of approx 30 min and overnight cure
Delivery was great and product worked ad Indecated without any problems!
Excellent adhesive. Needs better mix system.
I use flexible epoxies for ski construction and repair. In the past I've used 3M DP105, West G-Flex, and LocTite flexible marine epoxy. After working on 3 pair of skis with FlexEpox I prefer it to all the others. The only drawback is the very dark color, but this can be managed.I do not like the mixing system for the 8oz kit. The tubs are far too large to be useful. Ski repair uses very small quantities of epoxy and mixing enough for accuracy with this product causes quite a bit of waste.I would pay extra for this product if it came with a mixing nozzle type system like the 3M gun -- my usual trick of drawing from each bottle with a separate syringe, then mixing in a paper cup or on a disposable surface does not work well because the hardener is too thick to suck up with a syringe. Best thing I've come up with so far is to mix by *weight* using a paper cup and a jeweler's scale, but if you try this be aware the weight ratio is 1.2:1, not 1:1 like the volume would be.

TotalBoat FlexEpox Ipe Strength Test
FlexEpox strength test on resinous Ipe wood. Joint edge, sand 120 grit, wipe lacquer thinner 4X. Apply FlexEpox using gravity alone (no clamping). Cure 2 days/ ~70degF. Destructive impact test using hammer/vise. Test Result : Note pics indicate no glue failure. Last break occurring thru glue line.
So far . . . so good
I make cutting/serving boards that sometimes have cross-grain pieces. i.e. Long grain attached to short grain. So to accommodate wood movement I needed something with just a bit of flexibility AND would be waterproof. So far, this is working great. If you want to see what I mean by cross-grain you can see it here: https://www.corneroakswoodworking.com/portfolio
Even works on rubber!
Excellent adhesion and enough flexibility to secure rubber non-skid strips to the bottom of my laptop where all other adhesives from epoxies to contact cement failed. Just what I was looking for.
I use this product to reglue the glass window in the rear of a Volkswagen convertible top. It worked perfectly. Time will tell as to how long it's going to hold up but I have high hopes. So far so good.
Fort Wayne, IN
I am fixing up a used Laser for scout camp that was donated but the deck was separating from the hull, Flex epoxy seems to be the only product that holds them together. I have used it on Sunfish with the same issue to good effect.
If there is anything on the planet that it more sticky I have yet to find it.
