Cast lightweight hanging decorations and decorative objects that you can paint once dry. Pébéo Gédéo light plaster is a white, low-density plaster. Mix the powder with water and pour it into a suitable mould.
What is supplied?
- One pack containing 1 kg of white light casting plaster powder.
- A mould, mixing container, measuring cups, stirring tool and paint are needed separately.
Choose this plaster when low weight matters, for example for decorations you want to hang. The powder makes the cast, not the flexible mould. Use a mould suitable for plaster casting, such as a Siligum or latex mould.
Mixing and pouring
Measure by volume: 1 part water to 1.5 parts light plaster. Use the same measure for both; this is not a ratio by weight.
- Prepare the mould and a spacious mixing container. Pour the measured water into the container first.
- Sprinkle the plaster evenly across the water without stirring. Let it absorb water for about 1 minute, then mix gently for about 1 minute.
- Do not add more water after mixing. Pour slowly down the side of the mould to help limit air bubbles.
- Gently remove the cast from the mould after about 1 to 1.5 hours. This is the demoulding time; allow it to dry fully before painting.
Colour and finishing
The white surface is easy to paint. You can also add acrylic paint to the mixing water to colour the plaster throughout. Cold water slows setting; warm water and vigorous beating speed it up. Allow for this when working and follow the pack instructions.
Handling and storage
Do not breathe the powder dust. Handle the powder gently to limit airborne dust. Keep the pack tightly closed and protected from moisture.
