CALCESAN
Single layer dehumidifier based on natural hydraulic lime NHL 3.5
Description:CALCESAN is a dry premix based on micronized geo-pozzolan, NHL natural hydraulic lime in compliance with Standard EN 459-1, pure calcined kaolin and unground alluvial sands free from silt.
On the employment fields:CALCESAN is a multi-purpose fiber-reinforced mortar that can perform different tasks by simply changing the mixing water and mixing time.
CALCESAN, being based on natural NHL hydraulic lime, is particularly suitable for restoration and renovation of plasters in buildings of historical and monumental interest where the use of
cement-free systems is required and the presence of aggressive sulphate salts is frequent.
It can be applied to internal or external brick, stone, pebble or tuff walls subject to capillary rising damp and salts, including those of a sulfatic nature.
Thanks to its specific formulation covers the entire cycle of restoration, can be used as a covering coat, dehumidifying plaster and breathable finish.
Used as a rendering, it guarantees the adhesion of the subsequent layers of the restoration cycle to the substrate and, at the same time, it ensures excellent transpiration of the humidity contained in the masonry.
Used as dehumidifying plaster, thanks to its highly porous structure allows to capture the moisture in the masonry and promotes its rapid evaporation.
It also acts as a deposit for any salts carried by rising water, preventing the formation of efflorescence on the surface.
Used as a breathable finish, thanks to its strong water repellency, prevents the passage of water in liquid form but ensures the disposal of the same in the form of steam.
