RC KALEI

Lime render based on natural hydraulic lime of Saint-Astier

General

RC KALEI is a lime render based on natural hydraulic lime (NHL 3.5) of St. -Astier and mineral fillers. It is a thin plaster layer (2 - 4 mm) which gives a protective traditional structure to brick and natural stone. RC KALEI contains no cement and thus best approximates the age-old technique for the authentic finishing of exterior walls.

In damp weather, the lime render shows the famous "staining" typical of cement-free lime render systems. The correct dosage of lime and an ideal choice and structure of the granulometry of the fillers give RC KALEI excellent properties for applications in the restoration of facades.
