Castella Catalyst - The Engineered Liquid Activator

Castella Catalyst is a balanced activator designed specifically to work with Castella Engineered Craft Powder. It controls setting time, improves internal bonding, and ensures uniform curing throughout the casted piece. The catalyst helps reduce common casting issues such as weak spots, surface inconsistencies, and premature setting. When mixed correctly, Castella Catalyst enables predictable working time and consistent strength across batches, making it suitable for both beginners and professional makers. For optimal performance and durability, Castella Catalyst should be used as part of the complete Castella casting system.
