What is acid stain or chemical reactive stain?
Most acid stains are a mixture of water, hydrochloric acid, and acid-soluble metallic salts. They work by penetrating the surface and reacting chemically with the hydrated lime (calcium hydroxide) in the concrete. The acid in the stain lightly etches the surface, allowing the metallic salts to penetrate more easily. Once the stain reacts, it becomes a permanent part of the concrete and won’t fade, chip off, or peel away. Like stains for wood, acid-based stains are translucent and the color they produce will vary depending on the color and condition of the substrate they are applied to. Each concrete slab will accept the stain in varying degrees of intensity, creating natural color variations that bring character and distinction to each project. What acid stains don’t offer is a broad color selection. You willl mostly find them in a limited array of subtle earth tones, such as tans, browns, terra cottas, and soft blue-greens.
