Statuary Hydrocal- excellent plasticity, harder and stronger than Hydrocal White Gypsum Cement. Applications are solid and hollow art casting. Recommended for statuary castings requiring extremely hard surfaces. Best results are obtained when mixed mechanically. Use pure water.
Drinking water is considered pure.
Water temperatures affect the setting time. The warmer the temperature the faster the set. Temperature ranges for maximum solubility are between 70 and 100 degrees F. 3. This ratio affects the set time as well as the final density, hardness, strength an durability of the plaster form. It is recommended by the U.S. Gypsum Company water and plaster volumes be measured according to directions outlined on each product.
