Base plaster based on natural hydraulic lime for indoor use, especially for objects relevant to monument preservation. With limited possibility of use also outdoors.

HISTOCAL ® historic pure lime plaster CS I – inside, fine – consists of natural hydraulic lime (NHL) and white lime hydrate according to EN 459-1 as well as grain-graded crushed lime sand. HISTOCAL ® historic pure lime plaster CS I – inside, fine – is cement-free .

This high-performance product is suitable for indoor use , especially in renovation and monument preservation , as its grading curve is based on historical findings . It is highly permeable and moisture and climate-regulating . Due to its natural alkalinity, HISTOCAL ® Historical Pure Lime Plaster CS I – interior, fine – effectively prevents the formation of mould.

 

HISTOCAL ® historical pure lime plasters fulfill in an exemplary manner the reference to the historical findings - the lime mortar - required by the preservation of monuments. Through the interaction of hydraulic and carbonate hardening, HISTOCAL ® historic pure lime plasters set slowly and without tension . They have a low modulus of elasticity and can therefore easily absorb thermal and mechanical tension.
