About Natural Hydraulic Lime

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.
