The recommended plaster to water ratio is between 2.45:1 and 2.80:1, with a mixing time of approx. 2 to 4 minutes. Water and Plaster must be measured carefully to ensure constant performances. The precise consistency to use will need to be adjusted to suit the individual application. Changes to plaster to water ratio will influence product performance particularly setting time and strength.
