How do I mix Plaster of Paris?

Check the product instructions for the appropriate powder-to-water ratio before mixing. The previous listing's 2:1 ratio did not specify whether measurements were by weight or volume, so it should not be treated as a precise mixing specification.

1. Protect your work surface and measure the powder and water separately according to the product instructions.
2. Slowly sprinkle the powder into the water.
3. Allow the powder to absorb the water, then mix gently until smooth. Avoid vigorous stirring to minimise air bubbles.
4. Carefully pour into your mould. Work efficiently, as the plaster begins to set after mixing.

How long does it take to set?

Plaster of Paris sets relatively quickly. Setting time varies with the size and conditions of your project; a fixed setting or demoulding time is not specified in this listing.

Can I cast it directly onto hands or feet?

No. Do not cast Plaster of Paris directly onto body parts. Use a purpose-made, skin-safe life-casting material for direct body contact instead.

Is it suitable for children's craft activities?

Adult supervision and appropriate safety precautions are essential. Children should not handle or inhale the dry powder; adults should oversee mixing and casting.

Safety and disposal

• Avoid breathing the fine powder. Use suitable respiratory protection and adequate ventilation when handling dry powder.
• Wear protective gloves.
• Do not pour plaster into drains. Allow leftover mixture to harden fully before appropriate disposal.
• Do not use directly on the body.
• Refer to the product's Material Safety Data Sheet (MSDS) for detailed handling information.
