Professional-grade solution for lasting results. Review: Works, but is tricker to use than it first appears - 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.

It’s at least 24 hours between crack seal on outside and epoxy in the center. **Q: What is allowable temperature range for proper curing? Will cold weather affect proper curing?** A: Any concrete below 65 degrees F will delay cure time. The epoxy will still cure, but will take longer. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works, but is tricker to use than it first appears *by D***E on March 3, 2025* Product worked as advertised mostly.

It slowed down our leak. We just bought a second box hoping it completely seals it. We are also redoing some dirt work on the outside of the house to divert water. ## Frequently Bought Together - Polygem LCR Epoxy Concrete Crack Repair Kit - Stops Leaks - High-Performance Structural Bonding - Professional Grade - Reliable & Effective - DIY Friendly - Versatile - Wood, Fiberglass, Metal & More - Polygem LCR Injection Ports for Concrete Repair, 7-Pack with Attached Caps, Use with LCR Injection Epoxy and Repair Paste - LCR Injection Epoxy for Concrete, Fiberglass, Metal, and More; Combines Part A Resin and Part B Hardener for Use in One 10-Ounce Cartridge for Standard Caulking Guns; Use with LCR Crack --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/353621265-polygem-lcr-epoxy-concrete-crack-repair-kit-stops-leaks-high](https://www.desertcart.tn/products/353621265-polygem-lcr-epoxy-concrete-crack-repair-kit-stops-leaks-high) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-28*
