Best stuff I’ve found
This filler is so much better than the fillers stocked by the big box retailers. I love the mixing nozzle, and it’s way more fluid than the other fillers so it really flows into the cracks well. Since it is so fluid and soaks into the concrete so well, larger cracks may take more than one application. Tough and durable. The only drawback is that if you don’t or can’t use it all at once, the epoxy will harden in the nozzle rendering it useless for later use. But, fortunately you can order additional nozzles.

what a mess
too runny and it takes for ever to set so it just leaks out of crack. I used a similar product before which was setting in 5-10 min and that was much easier to use

Low viscosity epoxy
Excellent low viscosity epoxy for very narrow horizontal cracks Reviewed in the United States on February 28, 2026 Size: 20 AmpNumber of Items: 1 This is the second time using this product. As indicated it is LIQUID. Not a paste or a viscous material. I wanted very runny, (read not viscous) and it was exactly what I needed. The only complaint I have with this order is that the nozzle was missing. I kept the one from the previous order and reused it. You can clear/clean the inside of the nozzle with automotive brake cleaner and keep it for next time. Works very well in removing uncured epoxy.

Four days after application it is still tacky.
It has been four days since I used this product and it is still tacky. I can not recommend this product at all.

Mixing ratio of hardener incorrect occasionally?
Flows almost too well. Tip: Buy 4x what you think you need! The only issue I had is when pumping vertical cracks, I inevitably spilled some. The issue is that the puddles on the ground would sometimes take weeks to harden, and one spot is still like syrup, it never got hard.
