St. Astier Natural Hydraulic Limes

NHL2, NHL3.5, NHL5 and associated products

Hydraulic Limes are supplied as dry powders, and begin to set through a chemical reaction known as hydration when water is added to the dry powder. As such, NHLs will set in damp conditions and produce an earlier resistance to frost than Lime Putties.
