## Description

High-Performance Bonding: Achieve reliable and effective concrete crack repairs with the Polygem LCR Epoxy Kit. Professional-grade solution for lasting results.

Review: Structural repair not a water sealant
Review: 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.

*by C***I on 13 November 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!
