Pure, white model plaster, ideal for mold making as well as for the production of models from gypsum. The ratio of molding model spray to water is approx. 1.25 - 1.50 kg plaster : 1 l water.Step 1:The plaster powder is gradually introduced into the water and briefly given to the bottom. A rule of thumb is that the quantity of powdered plaster powder is ideal for the quantity of water when a small powder cone is left on the surface of the water and does not sink any more.Step 2: After this, the plaster slurry is carefully stirred until the entire quantity of plaster has dissolved free of clumps and without air inclusions.Step 3: After a few minutes, the plaster slurry is slightly thicker and is ready for pouring. It is not allowed to wait too long, since the plaster begins to build up with heat. This process takes about half an hour.Step 4: Finished plaster moullds should dry for at least 2 days to prevent them from breaking.
