EXADURO - Plaster for Molds and Counter Molds

Exaduro gypsum (plaster) is a calcium sulfate derivative indicated for the manufacture of models requiring high hardness and matrices in the ceramic industry and casting of figures.

MIXTURE: We recommend the gypsum/water ratio indicated below. Working with less water increases the resistances, but the time available for casting will be shorter.

Pour the plaster into the water (never the other way around), let it moisten and knead for about one minute, beating gently and uniformly to avoid the formation of air bubbles. The containers should be clean.

It is important to keep the water and plaster in an environment with temperature within the mentioned range before use.

The higher the water temperature, the shorter the setting time.

STORAGE: In dry places on wooden battens, separating the different rows from each other and from the wall so that air can circulate freely. In this way the plaster can be stored for months while retaining its properties.
