When artists use Plaster of Paris to create planters, castings and home décor things, they apply a release agent like the petroleum jelly to the plastic mould desired shape. After that, a thoroughly mixed paste of Plaster of Paris is applied to the mould and let dry for an hour or so. After that, the plaster gets removed from the mould. All the excess material is cut from its edges.
When Plaster of Paris is used to make sculptures, the artist makes a base of the wanted shape from various materials like newspaper, craft wire or other random household items. Armature is the base and it is needed to offer stability and strength. Armature is made with a spray release agent. It is then coated in a layer of Plaster of Paris.
Whatever it is that you are making, the item, after being coated with Plaster of Paris should be left to totally dry up for a minimum of 24 hours otherwise it will be difficult to decorate or paint it. The powder should not be mixed with bare hands or inhaled since it has chemicals.
