Description

A high grade powder when mixed with water produces a smooth white cast. Setting time is approximately 15-20 minutes. Mix four parts plaster to three parts water by volume or 1kg to 750cc’s of water. Use a clean mixing container and sift the plaster into clean water. Soak for 1-2 minutes allowing air bubbles to escape and stir to a creamy consistency, breaking up any lumps. The plaster may be harder or softer by adjusting the proportions of plaster to water.
