## Customer Reviews

### ⭐⭐⭐⭐⭐ Works, but is tricker to use than it first appears
*by D***E on March 3, 2025*

Product worked as advertised mostly. One tube's mixer did not separate from the foil which made mixing hard, but not impossible. FYI, of this happens do not push hard enough to dislodge the bottom, this is what some other reviewers are complaining about, but it's avoidable. Watch the how to vids on YouTube.Some helpful tips, since if you're reading reviews you likely haven't done this much:1. Be very thorough in putting the epoxy around the injector base. Use more than you think you need, you should have plenty of epoxy.2. Use nails to position the injectors against the crack, as they tend to move if you are not careful and might get blocked by epoxy.3. Have a quickset epoxy on hand before injecting in case you find any holes in your epoxy job.4. Use very little pressure, and watch the tiny bubbles in the nozzle to see if it's still flowing in. If it is not, it's likely the injector is blocked.5. Put down some sheets or cardboard, as you will likely leak the resin at some point unless you are very practiced.6. Each tube handles about 4 feet, but the kit only comes with 6 injectors. Where the crack is wider, you can put them much further apart than 8 to 12 inches as recommended. You can always order more injectors, but I doubt you really need them. Frankly if you need more than two tubes of resin, your crack is likely too big for this repair and you need a professional.

### ⭐⭐⭐⭐⭐ Product installed well
*by C***I on November 13, 2024*

If you follow the instructions, it works quickly and well. I was able to install 24 linear feet in an hour/1.5 hours. Allowed it to cure for 12 hours. Injected to thinner epoxy 12 hours later. Finished that process in less than an hour. Couple suggestions: make sure you cover over the crack thoroughly so you don't have leakage, when mixing the injectable epoxy, mixing the tube takes some finess to break the aluminum barrier and the screw in the mixer in the tube. Good luck!

### ⭐⭐⭐⭐⭐ Not as easy as seen in the video
*by F***E on March 20, 2023*

This thing gets really hard. I followed the instructions and then added my own instructions. The packaging says no drilling, but if I use this again, I’m drilling a hole before I install the injection ports. I had a very difficult time trying to squeeze the heavy liquid into the tiny crack on my wall. I thought I did something wrong; but then as I moved up to where the crack was bigger, it got easier to push it in. My last injection port was sealed properly so the epoxy started oozing out of the side. Make sure the injection ports are covered and sealed properly before injecting the epoxy. Make sure there no gaps left uncovered. If you leave any open space when the epoxy can sip out, it’ll ruin the job. Clean the surface very well before applying the sealant. I dropped some of the epoxy on the floor and that’s how I know that it gets really hard. I had to use a clap to squeeze the caulking gun because my weak hands were not enough for the job. I ended up with blisters on my hands. I placed Brad nails inside the injection ports going through the crack. I should’ve used finishing nails instead. It would’ve probably made the job easier. Good luck!
