This epoxy is great for stabilizing knot hole and voids in any kind of wood. And takes tint very well. And sands smooth.

Great Epoxy!
I used this epoxy to build my workbench. It is fantastic! Easy to work with. Easy to measure and mix. Long open time. Only drawback is a long cure time, which is longer in my unheated work area. Overall, great epoxy and I will use it again and again on other projects.

Good stuff, easy to use, solid
Bought this with some due to fill severe splits in some cedar before milling. I warmed it slightly by setting the bottles in warm water prior to mixing for about 5 minutes and it flowed well. Once cured it looked great and milled easily. The cedar didn't split or crack further and feltcompletely solid. And now, it looks like some viens of Amber are flowing throw it.

Jim T on Mar 9, 2017
BEST ANSWER: If I need it to match, I generally use fine sawdust mixed with the epoxy. Also I have dyed it in the mixing process but not after.
is this product paintable t88 structural epoxy?
mike m on May 22, 2020
BEST ANSWER: Because of how smooth the epoxy is it is possible to get pealing after the application of the paint. Paint adhesion relies on the mechanical grip of the paint keying into the sanding scratches in the epoxy’s surface. If a high-build or filling primer is to be applied, 80-100 grit is usually sufficient. 120-180 grit may be adequate for primers and high-solids coatings. Finishing with 220-400 grit paper will result in a high-gloss finish for most paints or varnishes. Grits finer than this may not provide enough tooth for good adhesion.

Is T-88 epoxy ok for Teak wood joints ? Hello friends,

I got a few indoor dining chairs made of teak wood.
Some of the joints are loose, some cracked, and some joints broken apart.
Would T-88 epoxy be ok on teak chairs, for indoor use ?
Thank you very much for your help!

julian j on May 15, 2018
BEST ANSWER: Yes, T88 works with teak very well. I have used it on teak outdoor furniture several times and it lasts.

Will it work on a surplus gun stock?
Haze1 on Apr 28, 2016
BEST ANSWER: For filling cracks it should work fine but if the stock is broken it would be better to buy/make another one. A rifle or pistol stock is nothing to go cheap with since you depend on the stock for your protection. This is a very strong glue with great adhesion that I have used for filling gaps in wood and pressing well machined wood pieces together to form cutting boards etc.
Can this product be used successfully for teak salad bowls? Obviously there is a concern for food safety (i.e. that the product doesn't leach harmful chemicals when coming into contact with food) but I'm also wondering about stability vis-a-vis salad dressing, esp. those high in veg. oil/vinegar. Comments, prior experience, and/or alternatives will be greatly appreciated! Thanks.
Paul R on Mar 16, 2016
BEST ANSWER: It can, but Teak is one of the species that contains high amounts of natural oils/wax, which prevents it rotting in the ground. It also contains high amounts of silica, which makes it tough on cutting tools. To remove the oils and wax in the wood, wipe the glue surfaces with acetone before applying. If you do an online search, enter 'gluing Teak'.
how do you mix this product?
ALEX S on Jul 22, 2015
BEST ANSWER: 1 to 1 by volume in a small paper cup with a wooden stick
