Otterbein Traditional Lime Plaster - Fine
HISTOCAL ® historic pure lime plaster CS I – inside, fine

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

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.

If it is necessary to improve adhesion or regulate the absorbency of the substrate, we recommend a net-shaped or full-surface pre-spraying with CALCEA ® lime plaster .

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.

Use coarse plaster as the base coat, and finish with the fine!
