Tonachino Materia

Pre-packaged finishing plaster in powder, mineral, breathable, eco-sustainable and bio-compatible, composed of pure aerial lime, micronized natural pozzolana, stone powders, calcareous-siliceous sands selected by colour and grain size, vegetal fibres, inorganic pigments and natural reinforcing micro-fibres along with specific additives to enhance rheological function. Absolutely free from salt and any form of clinker.

The binder contained in this mortar is a hydraulic lime, achieved by cold mixing high quality calcium hydrate obtained by burning pure well-selected limestone at a low temperature (about 850-900 °C) and pulverized natural pozzolana of various specific surface area and energy. The particular binder, called Calce Pozzolanica Pantheon – Calchèra San Giorgio, gives the dough excellent adhesion to the support, considerable elasticity (low elastic modulus), very high breathability, high resistance to alkaline aggressions, mould and bacteria formation. Free from substances harmful to health and environment. Recyclable as an inert material at the end of its life.
