Moulding Plaster, commonly referred to as “Plaster of Paris”, is a beta-hemihydrate gypsum product manufactured from high purity natural occurring white gypsum rock.
It is commonly used as a good white base material for formulating various interior oriented construction & industrial compounds, for simple 3-D statuary, architectural castings, and temporary templates where strength and hardness are not important.
TYPICAL PHYSICAL PROPERTIES:
- Use Consistency – 64-70cc/100g
- Set Time – 27-37 minutes
- Maximum Expansion (%) – 0.30%
- -100 Mesh – 98.5 – 100% passing
- +50 Mesh – 0% retained
- Dry Compressive Strength – 2,000 psi
GENERAL MIXING INSTRUCTIONS:
Plaster and water are always measured by weight. Using a plaster/water ratio outside the recommended use consistency guidelines will impact the set-time, strength and density of the finished piece.
- Sift plaster into water slowly and evenly.
- Let soak for 2 – 4 minutes. This allows the gypsum crystals to wet-out, displacing trapped air.
- Mix for 2 – 5 minutes
