Mix one part of water with two parts of Plaster of Paris. Too much water will cause cracking. Mix material slightly thicker for patching and repair. Mix material slightly thinner for molding applications. Use only clean water and containers when mixing.

Two parts plaster to one part water.

Three to one water for dental grade.
