  • What is consistency?

    Consistency is defined as the number of parts of water, by weight, required to produce slurry of specified fluidity when mixed with 100 parts of plaster by weight. Consistency is product specific, but generally, the lower the water addition, the thicker or less flowable the slurry will be. The more water you add, the “looser,” more free flowing the slurry will be. As consistency increases the strength decreases.
