(SLAKED LIME OR LIME PUTTY) (seasoned 8-10 months)
Air binding product according to traditional methods. Having carefully selected the stone, from the quarry, it is slow fired in specific furnaces at 950-980 °C, using sawdust as fuel. The quicklime, thus obtained, is subsequently “quenched” with plenty of water, giving rise to SLAKED LIME, or air-slaked lime. At this point, the product is left to cure in specific tanks, for at least 8-10 months: in this period the hexagonal crystals, composing the structure of the product, are gradually and slowly arranged in many parallel rows, making the lime putty more compact, sticky, tenacious and workable, therefore cured and ready for use.
Thanks to its natural characteristics, this product is perfectly in line with the current green building philosophy, always more attentive to health and safeguarding the individual and the environment.
