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.

Very runny , no body to it at all
The epoxy is not like any other i have used. No thickness at all and went right in the crack and through concrete and stuck to nothing. Has consistency of water Picture pouring water in the crack, if the water would not stay in the crack you are trying to fix then this stuff wont either. It would need a fully encapsulated area to fill up in order to work. I wish they would have said that it was runny and not paste or putty like every other epoxy i have used prior to me wasting my money.

Arrived damaged and missing nozzles
This review is about how they were received. I ordered 4 and 2 of them were missing the nozzle and one had a broken screw top. There is nothing to prevent the nozzle from falling out of the holder that is connected to the tube. I will write another review after I use the product.
