A range of colors for you to choose from. Acid staining is not a dyeing or pigment-base coloring systems, but a chemical reaction. A mixture of water, salts and acid is applied to the concrete surface and later neutralized by a basic solution of ammonia and water. This chemical reaction with the existing minerals in the concrete creates new colors on the concrete surface. Due to inconsistencies in the surface of concrete, acid staining creates a variegated or mottled appearance that is unique to each slab. The thickness of this color change ranges from 1/16th to 1/32nd of an inch. Remember, when choosing a color, the mineral concentration and other various characteristics of the slab will affect the stain's reaction. These colors are only examples of typical results on new concrete.
