Typical Uses:

- Modelling.

Unlike mortar and cement, Diggers Plaster of Paris remains comparatively soft after drying. Available in 1kg and 3kg.



  • Quick-setting – sets hard in 20 to 30 minutes.
  • Minimal shrinkage during setting as it hardens externally before water leeches or evaporates.
  • Will expand slightly upon setting giving a fine detailed cast.
  • Once coated with Diggers Raincoat the end product will be protected from moisture that might soften the plaster when placed outdoors.
  • Can be coloured with Diggers Oxide.


1. Ensure all utensils are clean.
