For a mixture, the recommended ratio of water to gypsum powder is approximately 1:2, but the amount may vary depending on the temperature of the water and the weather conditions at the time.
Do not mix or stir the plaster directly with your hands!!!
- Add water to the mixing tray.
- Pour or sift a small amount of gypsum into the water, and gently mix with a spatula.
- Tap the sides to vibrate and release air bubbles.
- When the mixture becomes smooth, uniform, and light grey in color, it can be poured into the mold.
