 limes hydroscopic capability - means absorbs moisture in air.

 advantages are there for natural hydraulic lime over fat/putty lime 

vapour permeable and allow buildings to breathe

Porous and open textured materials such as lime plasters,  absorbs and releases moisture based on climate  stabilizes humidity inside rooms provides reduced mould growth and provides extra comfort atmosphere, 

cracks can be easily solved by using water as the quality of autogenous, or self healing of cracks as it forms only many small cracks than large cracks in cement buildings.. 

free lime has Growth of Calcite Crystals than hydraulic limes and cements. provides strength open and permeable material

Disfiguring by time doesnt happen like in cement

very long self life when stored...  Indefinite
