Very expensive, tried different products and none worked. **Q: About how many square feet of will this cover? I understand it depends on the tile size and the actual amount of grout.** A: We have 20x20 tile on about 1200 sq. ft. in our new house. Two applications on ours and two applications on our neighbor's (same size) with about 1/3 left. So 6000 sq. ft. of tile coverage or more on this size of tile. It will depend on tile size with smaller tiles having more grout but it works great and it's fairly easy to apply....I used a roller applicator. **Q: Can this be used on a backsplash with white glass subway tile? Does it have an odor? If so how long does it smell?** A: 1) Yes let it set for 5 minutes they wipe off....2) Hardly any noticeable smell...its water soluble so it really does not have any long lasting odor... **Q: Can I put this in checked baggage on an airplane?** A: No. Have it shipped to wherever it needs to be applied. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great! *by M***S on 17 October 2022* ### ⭐⭐⭐⭐⭐ Very good product *by S***R on 10 June 2025* ### ⭐⭐⭐⭐⭐ Excellent product *by A***R on 7 December 2023* ## Frequently Bought Together - STONETECH Heavy Duty Grout Sealer, 1 Gallon (3.8L) Bottle - STONETECH Stone & Tile Cleaner, 1 Gallon (3.8L) Bottle - STONETECH KlenzAll Cleaner, 1 Gallon (3.8L) Bottle --- ## 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.tn/products/436674711-stonetech-heavy-duty-grout-sealer-1-gallon-3-785l](https://www.desertcart.tn/products/436674711-stonetech-heavy-duty-grout-sealer-1-gallon-3-785l) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-20*
