Values from the USG Datasheets, first value is Hydrostone, second is Hydrostone TB Mix Ratio, by weight, parts water to parts powder: 32, 30 to 32 Setting Time: 19-25min, 15-23min Compressive Strength, 1 Hour: 4,000psi, 3,000psi Compressive Strength, Dry: 10,000psi, 8,000psi pH: 7.73, 11.13 Max Expansion: 0.24%, 0.09% Setting time is influenced by the temperature of the water and powder when mixing. Temps in the range of 50-70F extend the setting time, while temps in the range of 70-90F shorten the setting time. Above 80F, the setting time may be just a few minutes. Compressive strength is influenced by completeness of mixing, and USG recommends a power mixing blade for larger batches. A kitchen whisk tool with vigorous motion works for small batches, roughly less than 0.5lb/250g. **Q: Would this be hard enough to cast small details without those small details easily breaking off? And strong enough to send through the mail?** A: Yes it is very hard. I mail things that are made of hydro stone all the time. I do wrap the thinnest pieces with extra bubble wrap. Hope that is helpful. **Q: Is this good for body casting art (pouring into the casted mold) or is there something better to use?** A: Don’t think it would be good for that because there are warnings that it can cause irrational or burns to skin. I used it for molding walls and floor tiles for miniature gaming. Worked great for that. **Q: How well does it take color?** A: Before painting you will need a clear sealer. I use spray paint. ## Frequently Bought Together - Hydro-Stone Plaster for Scenery, Dioramas, Dentistry and Mold Casting, Also Great for Model Railroads & Gaming 10 lb - Norpro Silicone Bowl Set 3 Piece Red 1019R - Eco Advance Concrete/Masonry Siloxane Odorless Spray-On Application Waterproofer Concentrate, Safe for Use Around Plants, Pets, and People, 1 Gallon --- ## 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.com.kw/products/483977649-usg-hydrostone-tb-10-lb-bag-gypsum-cement-extremely-hard](https://www.desertcart.com.kw/products/483977649-usg-hydrostone-tb-10-lb-bag-gypsum-cement-extremely-hard) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-20*
