Plaster of Paris is a top quality, quick setting plaster normally used in combination with gauged lime putty when a shorter set time is desired. It can also be used, mixed with lime putty, for forming plaster mouldings where required. Can be used in a variety of applications.
PREPARATION: To shorten the set time of gauged plaster: Pour approximately 30 liters of clean water into the centre of a ring formed from approximately 50 kg of lime putty. Slowly add the amount of Plaster of Paris that will give the desired setting time, along with the gauging plaster, into the water without allowing the plasters to come into contact with the lime putty. Add 1 part dry gauging plaster by volume to 3 parts lime putty by volume. After the dry plasters have soaked up the water, mix the plasters with the water and then thoroughly blend the plaster with the lime putty. Avoid scraping the gauging board while mixing.
