A lightweight plaster suitable for casting and hanging.
1.5 parts powder to 1 part water.
It is recommended to remove it after 30 minutes.
Preparation of plaster:
Pour the water into a large container. Spread the plaster all over the water. Let the plaster absorb moisture for 1 to 2 minutes without mixing. Then stir gently to allow the bubbles to rise. Do not add water after mixing. Slowly pour the plaster along the wall of the mold. For complex shapes, empty and start over.
Cold water will slow the gypsum to set, hot water or agitation will speed it up.
To speed up the drying process, place the object in the microwave for a few minutes.
The mixture of milk and water will polish the object, giving it a marbled appearance.
Paint the plaster blocks by adding acrylic paint to the water. Spraying it during preparation will create a marble-like effect.
