Concrete staining is a technique that adds permanent color for concrete surfaces, providing a unique, translucent, and earthy or rich appearance, unlike paint that simply sits on top. There are two main types of concrete staining services: acid and water-based stains. Acid stains chemically react with the concrete to create beautiful marbled effects in earthy tones such as brown, tan, and blue, while water-based stains are non-reactive and fill pores with acrylic polymers, offering a wider and more consistent color range. The process includes thorough surface preparation, stain application, and sealing for long-term protection and durability.
