About Saint Astier® NHL

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. Saint 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 Saint Astier® Natural Hydraulic Lime a pleasure to live with, but it is also healthy to live with. With no chemical additives whatsoever, Saint 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.
