Herculite Hardcoat provides a hard surface finish on cork or expanded polystyrene slabs for use in cold storage rooms, refrigeration chambers and in the lagging of ducts in heating installations. Its gradual setting property allows for ample opportunity to bring the plaster to a smooth surface finish. However, it's best known for its use in scagliola production, being the ideal material for it, according to its devotees!


Plaster/Water Ratio: 100/42

Set Time (mins): 130

Expansion: 0.30%

Compressive Strength: 19 MN/m2 


Fire Protection

The plaster is non combustible when tested in accordance with BS 476:Part 4:1970 and therefore satisfies the Class 0 requirement of National Building Regulations.
