Natural Hydraulic Lime (NHL) has been produced in Saint Astier, France since 30 BC and produced on an industrial scale, by the same families, since 1851. St. Astier Natural Hydraulic Lime is truly a unique and rich exterior finish. Unlike the cold, urban look and feel of cement, natural hydraulic lime is a time-honored, old-world finish, enjoying a modern comeback due to its soft, rich, and velvety texture. Its ability to absorb multi-nuances of color is enhanced by the varied angles of sunlight reflected throughout a day. This is a finish that improves with age, always evolving, deepening, and taking on a character of its own. Its warmth lures one to touch and invites one to linger. Not only is St. Astier Natural Hydraulic Lime a pleasure to live with, but it is also healthy to live with. With no chemical additives whatsoever, St. Astier Natural Hydraulic Lime is the ultimate safe, natural, green building finish product—a throwback to the old world, rediscovered to help the environment of our new world.
