50lbs HYDROCAL WHITE GYPSUM CEMENT

Additional shipping charge of $40 applies to this item. 

Offering twice the compressive strength of plaster, Hydrocal® White Gypsum Cement is especially suitable in thin, delicate sections where high green strength is required. Requiring 45 parts water per 100 parts plaster by weight, it offers longer workability, setting 25-35 minutes after mixing.
