Hard-drying casting plaster with around 15 minutes open time and a 20-minute set. Suitable for a wide range of craft moulds and model work.
Crisp detail reproduction - with a 15-minute workable time
A 15-minute workable window allows mixed plaster to flow into fine mould cavities before curing begins. The formulation then sets to a hard finish within about 20 minutes.
Produces casts that retain very fine textures while leaving a silky, durable surface that simplifies demoulding and finishing.
Fast workshop cycles - with a roughly 20-minute set time
Setting in around 20 minutes enables multiple casts during a single session, reducing downtime between pours. Short cure times suit batch work and iterative prototyping.
Useful for makers who need quick turnarounds and the ability to complete several small runs in one sitting.
Straightforward handling and finish - with hard-drying behaviour
Hard-drying behaviour yields a solid end result that users report as easy to demould and resistant to light damage. Reviews note a silky, durable surface on finished casts.
