Is this a grout? Is it suitable for 1/16" grout lines between normal tiles?** A: This is a caulk. I am not an expert but would not use to repair floor tile grout. I used it to fill seem between counter top and back splash. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect *by C***L on July 11, 2023* Couldn't find sanded caulk at the big stores. So glad to find it on Amazon - exactly what I needed for my walk in shower. ### ⭐⭐⭐ Does the job OK *by D***O on November 17, 2023* I ordered two tubes and the color was consistent between the two nor did it entirely match the (supposed) matching grout. It’s better than nothing but could be better ### ⭐⭐⭐⭐⭐ Great for use on tilre flooring *by R***. on July 23, 2022* Great where original caulk comes out of tile flooring. Elasticity so when tiles give the grout does not crack. The caulk moves with it. ## Frequently Bought Together - Mapei Keracaulk S Sanded Caulking (Bone) - Mapei Keracaulk S Sanded Caulking (Biscuit) - Mapei Keracaulk S Premium, Paintable, Sanded, Siliconized Acrylic Caulk, Expertly Formulated to Match Grout Colors, 10 oz., 5077 Frost- Sanded --- ## 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.co.uk/products/42607317-mapei-keracaulk-s-sanded-caulking-bone](https://www.desertcart.co.uk/products/42607317-mapei-keracaulk-s-sanded-caulking-bone) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-20*
