USG Hydrostone 25lb Box

USG Hydro-Stone® Gypsum Cement is especially suitable where high strength and resistance to water absorption are necessary. It is ideal for applications in both the tooling & prototyping and art & statuary categories.

USG Hydro-Stone® Gypsum Cement — For Tooling & Prototyping

USG Hydro-Stone® Gypsum Cement is ideal for stretch-press dies where extreme surface hardness is required. Offering greater expansion than USG Hydrocal® gypsum cements, USG Hydro-Stone® Gypsum Cement:

• Features a heavy, syrupy consistency, ideal for pouring into solid models or patterns (and making it ideal for filling multiple molds simultaneously)
• Adapts to most flexible moulding compounds, due to its high absorption resistance
• Sets in 17-20 minutes, after machine mixing
• Requires 32 parts water by weight per 100 parts plaster.

NOTE — For best storage results, keep indoors in a dry, stable environment, away from drafts. Do not stack more than two pallets high.

One of the hardest and strongest USG Hydrocal® products, USG Hydro-Stone® Gypsum Cement is used in the fabrication of high-quality art novelty and statuary castings. Offering excellent paintability, USG Hydro-Stone® Gypsum Cement:

• Can duplicate extremely fine details
• Works well in plaster and most flexible moulding compounds
• Is self-leveling, with low viscosity
• Provides fast set time for quick mold turns
