Crystacast

Crystacast is a high-strength, off-white casting gypsum that produces exceptional detail and surface strength.

It is a hemihydrate plaster produced from high purity gypsum mineral.

Plaster-based products are not usually recommended for outdoor use where weathering and excessive dampness is apparent. However our additive can be used to enhance the material to produce an outdoor-friendly casting, resistant to wet climate conditions.
