Slaked lime of KFN

Wood-burnt marble slaked lime - Calcium hydroxide Ca(OH)2

Construction industry professionals hold the exceptional features of our purely mineral slaked lime in high esteem. Especially in the conservation of monuments, as in the plastering and painting of historic frame houses, this special calcium hydroxide products plays a decisive role. 

Traditional burnt lime for construction professionals

Traditional slaked lime is made from lime guaranteed to be wood-burnt, and very finely ground. With an exact amount of water the burnt calcium oxide is slaked in a tightly monitored procedure and then diluted with water to the point that the so-called lime putty comes into existence, a watery calcium hydroxide paste.

For highest standards in construction

Stored protected against frost, the Ca(OH)2 thickens in the course of several months to form lime putty, a perfect raw material to make masonry mortar and plaster or for paste-like paints.

Highest purity

The KFN lime comes from the Elggis mountain and its content of CaCO3 is naturally high: it is above 98 %.
