GENERAL MIXING INSTRUCTIONS:
Plaster and water are always measured by weight. Using a plaster/water ration 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 1 minute. This allows the gypsum crystals to wet-out, displacing trapped air.
- Mix for 3 minutes.
