Regeneration paste for oil sand/oil moulding sand This offer includes 100g-1kg regeneration paste for oil moulding sands. In order for burnt moulding sand to be reused, it must be mixed with regeneration paste and oil. 1kg of moulding sand requires approx. 2g of paste and 2g of oil. The black oil sand produced after thorough mixing is suitable as a filling material. However, for an optimal mould with a high level of detail, new sand should always be applied finely to the positive. The regenerated sand should not come into contact with the moulded part and can be used to fill the rest of the mould.
