Diggers Plaster of Paris is a fast setting casting plaster commonly used for modelling and repairs to ceilings and walls.

Unlike mortar and cement, Diggers Plaster of Paris remains comparatively soft after drying.

Available in 1kg and 3kg.

Typical Uses:

  • Grouting.
  • Repairs.
  • Casting.
  • Modelling.


  • 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.
2. Add 1 part water to 2 parts Diggers Plaster of Paris and stir the mix to a creamy consistency.
3. If a colour is required, Diggers Oxide can be added to the mix. Mixture will set in approximately 15 minutes.
