Excellent batch to batch consistency. Increased strength and surface hardness compared to Fine Casting Plaster Good reproduction of fine detail Shelf life of 9 months Plaster to Water Ratio (by weight) 1.43:1 Water to plaster ratio ( by weight) 70% Plaster to water mix ratio (by weight) 100/70 Chemical Properties: Chemical Name: Calcium sulphate hemihydrate Chemical Composition: CaSO4 .1/2 H2O Setting Parameters: Initial setting time (minutes) 20 Final setting time (minutes) 25 STORAGE: Plaster based products are not recommended for conditions where they are likely to be located externally or in any way subjected to weathering or excessive dampness. Absorption of moisture can result in changes to physical properties, including a reduction in the set strength of plasters and also a lengthening of setting time. Gypsum minerals can be affected by absorption of moisture and may change physical properties. ghly until a dense consistency Once firm the compound can be smoothed with wet hands Drying Time: 15 Mins (approx) Compound can stay damp to the touch for 24/48 hours, but can still be painted and worked upon after 30 mins (approx)
