HydroCast Mineral Casting Compound Starter Kit
HydroCast is a sustainable mineral-based casting compound designed as an environmentally conscious alternative to traditional resins. The kit uses a simple 3:1 mix ratio, combining a mineral casting compound with an acrylic hardener to create a smooth mixture that cures into a material resembling natural stone. With a natural matte finish and excellent detail capture, it is ideal for home décor, functional pieces and creative craft projects.
The mixture can be customised easily with pigments, terrazzo-style chips or surface finishes such as paint or sealants. Because HydroCast sets quickly, it encourages a steady working pace and efficient production. If the mixture begins to thicken after sitting too long, it can be refreshed with a small amount of additional catalyst. The kit includes scoops to make the 3:1 ratio straightforward and reliable for beginners and experienced makers alike.
