Tenax Knife-Grade Super Transparent Adhesive - 1 Liter

This stuff worked amazingly well. I used it to repair cracks and to patch a granite countertop and it has held very well for 8 months now with no signs of wear. After patching, I was able to sand and polish. I was even able to crush up small pieces of granite and mix it with this to nearly match the appearance of the granite. I'd highly recommend the stuff.

Bought this product because our current supplier was out of epoxy that we normally use. This did NOT come with hardener, which it stated, but gives no recommendation on how to obtain it. That being said... we used this product to cover holes on a restaurant floor that were rather large (some holes a CD size in width, and 1/4-3/4 inch in depth). We used a clear hardener catalyst that we've used with other Tenax products that we stock on our shelves. After 30 minutes, it did not dry. After an hour, it did not dry. Being on a short timeline because of the nature of a restaurant, I had to remove all the undried epoxy, double my mix ratio from 3% to 6% and reattempt. About 50% became hard enough to sand down within the hour and the other 50% resulted in a firm rubber texture. They had to be removed.I went back to the manufacture. Issue #1, EVERY can of epoxy leaves the warehouse with a tube of hardener. So... what happened to it then??? This product cannot be used without it, so why sell it? Issue #2, this product as verified by its batch number was nearing the end of its shelf life. Still good technically, but nearing its end. After all was said and done, we spent hundreds of dollars in return trips messing with this epoxy and ended up using a different brand. On a normal day, I wouldn't even have had the patience to write a review this long, but since its two weeks over the authorized return date, I felt obligated since I cannot return it.

As advertized. Good value I paid the same price for a quarter of the volume at my local tile store.

Good stuff. Well packed for shipping.

Be careful when ordering. The picture shows the hardener read the fine print to see if it actually comes with the epoxy. Had to order the hardener after receiving the original order

I liked it.

Mixed at the right ratio (100-3) with Tenax Polyester Hardener and it did not set in 5 hours. Cleaned stone and tried again increasing ratio to 100-6. Still did not set.

Works great
