Cast stone products are available in a choice of 3 acid stains and 8 exclusive natural pigment stains in addition to natural cast stone. All of our patinas and acid stains are pigment based and hand applied in a multi-step process. Our artisanal finishing techniques make every piece a uniquely beautiful original. Our Latinas are designed to replicate the look of naturally aged materials and will not prevent the natural aging process. Any cast stone item with a patina finish will weather naturally in an outdoor environment.

Acid stains are a mixture of water, metallic salts, and muriatic acid. They work by penetrating the surface and reacting chemically with the hydrated lime (calcium hydroxide) in the cast stone. The acid in the stain etches the surface, allowing the metallic salts to penetrate the surface. This process creates a rich permanent stain on the surface of the concrete which should not flake or peel. 

Like stains for wood, each piece will accept our patina so in varying degrees of intensity, creating natural color variations that will add character and distinction to every piece. even when the same stain is applied with the same process, no two pieces will look exactly alike. This is due to the variance in the composition of the natural materials in the cast stone, as well as the varying ages of the pieces. It is this variability and broad range of tones, rather than uniformity, which give our stain their beauty and appeal.

Because each patina is hand applied and our products are photographed in natural settings, actual colors may vary from those depicted in the catalog. Please consult our catalog photos and our website for examples of variations in our patinas.
