  • Tap water is fine to use if you have soft water at home. Hard water and mineral water can prevent the plaster from drying completely.
  • If you have hard water at home, use distilled water instead.
  • Add small amounts of water at a time, stirring in-between.
  • Room temperature affects the drying time. Plaster dries more slowly in colder temperatures.
  • It takes 15-20 minutes for the plaster to set, depending on room temperature.
  • Wait 2-3 hours for the plaster to cure completely before handling or painting.
