What happens if I don’t follow the 10:3 powder-to-water ratio?

Deviating from the ratio may result in uneven curing—too much water can cause softness or cracking, while too little may leave the mixture dry and difficult to mold.

Can I use this powder in cold environments?

Curing time is extended in cold temperatures. For best results, work in a room above 20°C (68°F) to ensure proper 30-minute demolding and 2-hour full curing.

Is it safe to use with food-contact items like coasters?

Yes, once fully cured, the product is non-toxic and heat-resistant, making it suitable for coasters and other food-safe home decor (avoid direct contact with hot liquids over 80°C/176°F).

How do I store leftover powder?

Seal the powder tightly in its original container and store in a cool, dry place. Avoid moisture to prevent clumping; it remains usable for up to 12 months under proper storage.
