System Three T-88 1:1 Epoxy Kit, Amber, 16 fl oz, Woodworking, Marine, Industrial

Q: What is the working time on this epoxy kit?

At 70 deg you've got about 45 minutes of work time. For every 18 deg above 70, the time is cut by 1/2. Example: At 88 deg you've got about 20-25 min. This glue is structural and gap-filling, even mixed with cotton flox to a consistancy of creamy peanut butter.

Q: Is this sand-able without caking up sandpaper?

I sanded it and it didn't gum up the sandpaper, but it was a small patch.

Q: Would this work to fill surface scratches/gnawing in bamboo flooring? Max 1/4" deep and maybe 2-3" across.

I believe it would fill your scratches but if they’re 1/4” deep you may have to apply second coat as the liquid will leave a low spot because of shrinking.

Q: What is the difference between 1100k10 and 1100k14 t-88?

I’m not sure whether there is any difference except that the kits contain different amounts. I’ve purchased both kits and didn’t notice any difference in performance or appearance. T-88 is almost the standard epoxy for building wood aircraft. I reach for it any time I need joints to be absolutely waterproof and I have the time to let it set up. You could call the manufacturer . They are very helpful.
