TotalBoat Thixo 2:1 Epoxy System

TotalBoat Thixo is a thickened epoxy adhesive that gives you the reliability and strength of a modern 2:1 epoxy system in an easy to use 185ml cartridge. This convenient point and shoot system is ideal for bonding wood, metal and fiberglass above or below the waterline.

Thixo cartridges fit standard caulking guns. Lay a bead of this non-sagging adhesive to vertical or overhead surfaces. TotalBoat Thixo cures to a hard, translucent surface that can be drilled, painted, or sanded. This no-mess, no-hassle versatile 2:1 epoxy system comes equipped with two free static mixing tips to ensure accurate mix ratio upon application every time. Ideal working temperatures range from 50-80 degrees F.

Cartridges are available individually and in packs of (6) cartridges. Additional mixing tips old separately. Note: For use in manual caulking guns only.

Works great


No sag, flows out smoothly and cures hard.




Great stuff


Worked Great for me the only problem with it is it is very expensive for volume you get out of the two


Ontario ca


Great product


Used it to fill some old screws holes, very easy to use. Sands nicely. Solid product !!!




Works well and easy to apply


Thixo tubes are easily used in a caulk gun with 13:1 or better mechanical advantage. Just remove the cap, attach the mixing nozzle, trim tip to desired opening and squeeze the caulk gun handle. When done just release the pressure, toss the spent nozzle and re-cap the tube. Just attach a new mix nozzle when using again.I used it to replace rotten wood in Andersen "Permashield" vinyl-covered window sills. It worked great filling the void left after removing the rotten wood with hard, strong and waterproof epoxy!

Small aera fill


Great for filling small areas, unfortunately the mixing nozzle is not cleanable, so need new one for further work. So far I have not tried using it after the first round, but the two parts of the mix are still soft.

I would buy this product again


I used this to glue plywood sides and bottom to frames and other structural members for a skiff I am building. The glue worked perfectly with hand clamps. It did not run on vertical surfaces. The mixing tips worked great also. It does take some strength to gun a couple of tubes, but you have quite a long working time so there's no need to rush. It makes for much less mess than sometimes results from mixing large batches of thickened epoxy.

hard to pump out, applicator tip clogs


like others have stated, the applicator mixing tip clogs easily. maybe it just needs really warm temperature but I wish it would come out! eventually, you cut it open and mix it manually which you can simply do with regular epoxy and thickner.

Good Stuff


I really liked this product. I filled over 80 interior screw holes in under an hour in a 1976 13 ft. Boston Whaler Sport I found to restore for the grandkids. Some of you may say this was slow but bear in mind I'm 74 years old and not as quick as I used to be. Also, I used a standard caulking gun and after a while I found myself using two hands to squeeze the stuff out so get a better one. But I got 'er done. Zap, and the screw hole is filled. Zip, along a gouge and it's filled. After all was filled I took a Popsicle stick and gently pressed on the filling. This was what the Boatworks guy recommended in his video but I found afterwards it seemed unnecessary. We will see when sanded.

Right product for the right job


Thixo Epoxy system cartridges are easy to use and with the mixing applicators, any amount, from a very narrow bead to bulk applications can be applied to the work site. It makes incredibly strong bonds with wood and fiberglass. For doing small jobs, over time, where there is half a tube or more left after using both supplied mixing applicators, having a third available would be nice. Otherwise, you'll need to order a pack separately. Great product though and just ordered two more to keep on hand.
