Calcidrata products are made with raw materials analysed in our laboratories, where the best Sardinian limestones are selected including those of the Orosei Marble District, a compacted coralligenous and bioclastic limestone, resulting from the deposition and stratification of shells, which allows us to obtain a top quality lime. The limes obtained through the controlled slaking of the oxide resulting from the calcination at about 900° C of the best Sardinian limestones are used in agriculture, by using the Agricalcium product to correct the soil pH, and with Calce Idrata (hydrated lime) and Fiore di Calce (hydrated lime powder), due to their high chemical-physical properties, excellence and purity, in water treatment, desulphurisation, disinfestation, soil stabilization, creation of eco- friendly floorings and neutralization of acid substances. Through the slaking of the same oxide obtained from the calcination of the best Sardinian limestones, the company produces a refined lime putty. The product undergoes a cyclonic separation process and is left to mature in tanks for years. These processes allow the development of a macro- crystalline structure, which gives cohesion, plasticity and thixotropy to the lime putty. For this reason, it is highly appreciated by restorers and used in the restoration of paintings with historic-artistic value. Thanks to its high yield and covering power the product is ideal for preparing quality finishes and highly breathable paints. Over the years new products were added, such as the premixed lines consisting of plaster, masonry and screed mortars, glues and special mortars, during a continuous research and innovation to meet the market and customer needs.
