Review: Does the Job, and Does it Well - The color isn't perfect, but I didn't expect it to be. This stuff dispenses well and sets up fairly quickly. Dries hard and seems to be holding up well.

I used it on a foundation and it worked great! **Q: Is this good for sloped concrete pads?** A: Depends on how severe the slope is but it should work otherwise. **Q: Can you use it to reset a loose fireplace hearth stone?** A: For that I would use a construction adhesive, not a caulk. **Q: Can you use this on indoor concrete walls?** A: I've used this product on inside concrete cinder block walls with no problem. I like its textured consistency. Know that this product will break down over time when exposed to direct sunlight like a west or south facing concrete outside wall. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good item. *by W***W on 26 June 2026* Appears to be a good product and it should work well. ### ⭐⭐⭐⭐⭐ Does the Job, and Does it Well *by N***I on 5 June 2025* The color isn't perfect, but I didn't expect it to be. This stuff dispenses well and sets up fairly quickly. Dries hard and seems to be holding up well. Beats the heck out of mixing typical mortar and spreading/pushing it into place. ### ⭐⭐⭐⭐ I missed realizing this is caulk. It doesn’t harden up. *by P***K on 26 August 2024* I thought this was mortar in a tube. It’s husky caulk. I carelessly applied this product between bricks to replace missing mortar. I added sand to the top. It looks fine. But don’t imagine this stuff has the structural integrity of mortar. However, It does keep water, dirt and weeds out of the voids in my brick staircase. ## Frequently Bought Together - Red Devil 0646 Concrete & Mortar Repair (2 Pack) - Sika - Sikacryl - Gray - Ready-Mix Concrete Patch - for Repairing spalls and Cracks in Concrete and Masonry - Textured - 1 qt - Red Devil 0644 Pre-Mixed Concrete Patch, 1 Quart, Pack of 1, Gray, Made in USA --- ## 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/515820823-red-devil-0646-concrete-and-mortar-repair](https://www.desertcart.pe/products/515820823-red-devil-0646-concrete-and-mortar-repair) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-08-15*
