Thixo Flex is a thickened epoxy adhesive that forms flexible, high-strength bonds on wood (even teak and other oily woods), fiberglass, metals, glass, & some plastics. Upon cure, it creates permanent, structural bonds that absorb shocks, stresses, & vibration.
This cartridge-dispensed non-sagging epoxy is great for building or restoring wooden boats prone to flexing during use, and movement from weather-related expansion & contraction. Thixo Flex can be applied to dry or damp surfaces in temperatures as low as 40°F. You'll appreciate the long working time & easy cleanup.
Handy cartridges fit most standard caulk guns. Use the included mixing tip to measure, mix, & dispense a bead that's the precise 1:1 mix of resin and hardener to get a proper cure each time. No need to measure, mix, or worry.
One 250ml cartridge includes 2 static mixing tips.

In addition, Thixo Flex has higher flex tolerances and lasts longer than flexible, one-part urethane adhesives and sealants.
Application Notes: Store Thixo Flex cartridges at room temperature (60-90°F) before use. Apply when the temperature of the ambient air and substrate is 40°F or warmer. When finished, leave the static mixing tip on the tube to cure. For the next application, simply remove and replace the tip. Do not attempt to clean the tips.
NOTE: Thixo cartridges have a slightly offset nozzle that fits most, but not all, caulk guns. Caulking applicators used with Thixo need to have a hole large enough for the mixing tip; cartridges won't fit applicators with only a small hole for the nozzle. For best results, use a caulk gun with an 8 to 1 thrust ratio or higher. For use in manual caulking guns only.

I had an external crack in Gelcoat mid boat and removed a small section of the Gelcoat and fiberglass down to wood. I added a wood hardened I flex flex applied in one coat, sanded smooth. Smooth, really great product. Stuck hard to edges of Gelcoat. It didn't sag and I laid it on pretty thick.

Just reattached an 18" x 4" x 3" concrete trim piece which broke off the edge of my front porch floor slab. 1. Sure glad I read the reviews which recommended an 18 to 1 ratio of dispenser handle travel to plunger travel to make it easier to squeeze out the Thixo Flex. Don't know how you could do it with the standard 8 to 1 dispenser. But found an even better dispenser from "SolidWork." It has two selectable ratios, 12 to 1 and 24 to 1. I used 24 to 1. Made the job a piece of cake. 2. "When finished, leave the static mixing tip on the tube to cure. For the next application, simply remove and replace the tip." Quoted from the ThixoFlex cartridge instructions printed on the tube.

I watched Andy from Boatworks Today use this product on cracks in gelcoat and decided to give it a try. I am very pleased with the outcome so far and will be using it again on an extended project this fall.

USING THE TOTAL BOAT TUBE EPOXY TO REPAIR A SECTION OF DECK THAT WAS REMOVED FOR REPAIR BELOW THE DECK..HAD A PROBLEM WITH ONE TUBE, IT DID NOT MIX WELL FOR ABOUT A QUATER OF THE TUBE. I DO NOT KNOW IF IT WAS THE TUBE OR THE MIXING TUBE THAT WAS THE PROBLEM.

Great to get "premixed" epoxy but still some waste. Great for large projects that need at least 1/2 of a tube or more. Long open time. Needs a quality caulking gun to extrude the viscous epoxy

I used the Thiso fast cure to reattach the deck on my 15' sailboat. The deck was completely separated from the hull and the external joint sanded clean. After cleaning the seam with Thixo the deck was clamped for 24 hours. The result was amazing. The boat weighs 400 lbs however I believe I could lift the whole boat just by the deck alone. I'm not going to try this but, the ddeck/hull joint is amazingly strong. This is a great product and I will continue using it.

I am using this product (16 tubes so far, with 6 more on the way) to fill cracks in our peeled log posts and railings on our porch and 3 small decks at North Lake Tahoe, CA. Sun, low humidity, snow and low temperatures have caused them to dry out and crack, with some cracks over a half-inch wide. I strongly recommend you buy the NYC-250 18:1 thrust caulking gun to push the 2-part epoxy through the mixing tube. It costs 3 times more than the NEW-111(10:1 thrust) that was first recommended to me, but it works 3 times faster and has never jammed like the NEW-111. Note that the tubes are only about one-third full. I check with a measuring tape from the bottom of the outer cylinder to the bottom of the inner one to determine how much is left. The tube is empty when the measurement is 4 inches. Haven't been through a cold winter yet, but the epoxy had no problems with a couple of nights at 24 degrees.

I live in snow country at North Lake Tahoe, CA, elevation 6,300'. Many of us here have deck and porch railings and posts constructed with peeled logs 3" - 7" in diameter. Deep cracks occur in them after years of sun and snow and it is very expensive to replace them, so I was very lucky to discover Thixo Flex 2-part injectable epoxy. Although I'm having some challenges using the NEW111 10:1 ratio caulking gun, I'm optimistic about the NBC-250 18:1 ratio gun that I have ordered. Besides being strong, the epoxy is great since you can mask off anything that you don't want the epoxy to stick to. For me, I fold in half pieces of clear packaging tape, adhesive side to adhesive side, and tape pieces onto the bottom of the cracks and between the bottom of the posts and the Trex-like deck material under them with blue painters tape. Then I inject the epoxy, push it down to the tape on the bottom of the crack, let it dry and then pull out the tape easily. Haven't gone through winter yet, but it'll be 16F tonight and hopefully we'll have plenty of snow and cold nights this winter to test the repairs.

I used this to repair 8"x8" wood lintels over windows, which had deep cracks. This flexible epoxy is harder to dispense from the tube than the standard epoxy. Also, I found an inconsistency in the color of the epoxy being dispensed from tube to tube. One tube came out dark brown while the 2nd came out tan. Both hardened up well. On a vertical surface it will sag some if filling a deep groove, but can be troweled smooth as it firms up.

After seeing some YouTube videoshow to use this product, I bought Newborn 250 Super Smooth Rod Revolving Frame Caulking Gun, 1/10-Gallon Cartridge Capacity, 18:1 Thrust Ratio and it worked as expected. This reviewer complaining about how hard is to squeeze the resin out from the mixer tip should just use the proper tool for dispensing. The mixer tip works well but of course one needs to either sacrifice the first one ounce or a bit more or to mix additionally after it is out from the tip. After that the tip is mixing very well and the results are exactly as expected - tough but flexible resin.
