USG Hydro-Stone Gypsum Cement – 50 Lb Bag

USG Hydro-Stone is exceptionally strong gypsum cement that produces high-quality, indoor novelty and statuary castings that require extremely hard surfaces and superior reproduction of fine detail. Superior expansion vs. Hydrocal A-11 or B-11 gypsum cements. Hydro-Stone Gypsum Cement is especially suitable where high strength and resistance to water absorption are necessary.

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

• Can duplicate extremely fine details
• Self-leveling, with low viscosity
• Works well in plaster and most flexible moulding compounds
• High water absorption resistance.
• Provides fast set time for quick mold turns (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.
