Quick Project Turnaround – With 20-minute set time
Formulation reaches an initial set roughly 20 minutes after mixing, achieving a hard-drying finish suitable for handling. Fast chemical hydration reduces wait time between stages.
Allows rapid progression between shaping and finishing, useful when sequential steps must be completed on the same day.
Accurate Shaping and Detail – Thanks to 15-minute workable time
Powder mixed with water produces a paste that remains workable for up to 15 minutes, giving time for pressing into moulds and refining edges. The working window balances fluidity with controlled stiffening.
Gives sufficient time to reproduce fine detail in moulds, trim coving edges and correct minor imperfections without rush.
Clean Mixing and Economical Use – With smooth-mixing bulk formulation
Powder blends smoothly into a lump-free paste when mixed correctly, and the bulk pack provides multiple uses per bag as noted by users. Consistent texture reduces waste during preparation.
Easier mixing means fewer discarded batches and one bag can cover several small projects, making supply management simpler.
