I used it on a flat concrete surface and it worked just fine. it's a two-part epoxy and the tip swirls eack part mixing it as it comes out of the tip. **Q: I have a concrete fountain that has a crack/leak. Will this product be waterproof once cured?** A: generally yes, but it does depend on the size of the crack and the preparation of the crack before application. You also need a good caulking gun because the product mixes in the nozzle and without a quality gun it will be hard to mix and apply. **Q: Does this color match aggregate concrete?** A: The filler is clear when it dries. You can easily part my over as we did in our basement and garage. It is highly concentrated and only cover a small difficult area. So make sure you plan ahead of applying it. ## Frequently Bought Together - RTG Concrete Crack Filler - J-B Weld 40006 Wood Restore Premium Epoxy Putty Kit - 32 oz. - Minwax 41700000 High Performance Wood Hardener, pint --- ## 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.be/products/41430436-rtg-concrete-crack-filler](https://www.desertcart.be/products/41430436-rtg-concrete-crack-filler) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-06-25*
