You are basically making a super polymer concrete. I mixed with sand (unfortunately I used a tan sand from Amazon instead of gray) and it looks great. Its like welding concrete cracks to make them super strong. Its a runny mixture out of the gun so be prepared, and maybe work on a crack away from the center until you get your skills together.Not only is the product amazing for fixing cracked concrete, the seller is awesome also. They took care of me when I ordered the wrong color and didn't know it for 5 months. I will definitely buy this product again. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars does no go very far *by R***R on Reviewed in the United States on June 27, 2019* Excellent product easy to use. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/39025195-roklin-systems-inc-polyflex-ds-concrete-crack-filler-quick-drying](https://www.desertcart.pe/products/39025195-roklin-systems-inc-polyflex-ds-concrete-crack-filler-quick-drying) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-08-07*
