Characteristics

CALCESANA is the result of a firing process which, due to the inherent properties of the furnace, and to stringent controls, takes place at temperatures of 1100°C. CALCESANA is reduced to a very fine powder with traditional grinding processes unchanged over time. CALCESANA confers remarkable breathability properties to mortars and plasters, as well as outstanding characteristics of resistance to chloride penetration and corrosion from sulphate waters, even with high values of free carbon dioxide. CALCESANA is characterised by low soluble salt content, by the total absence of cement and chemical additives, and by its high inhibiting power against bacteria and biodeteriogenic settlements (moulds etc. ).

Use method

Extend mixing times for at least 5'. Apply on supports saturated with water, with dry surface. Do not add chemical additives without consulting our Technical Service first. Cure the convenient and prolonged moist hardening of fresh mortars and plasters. Protect the fresh mortars and plasters from direct exposure to the sun and ventilation.
