Concrete staining is a process that enhances the appearance of concrete surfaces by applying a colored stain. This stain penetrates the surface, creating a translucent finish that can mimic the look of natural stone or other materials. It is commonly used in both indoor and outdoor settings, providing a durable and aesthetically pleasing option for floors, patios, and driveways. The staining process typically involves cleaning the concrete, applying the stain, and sealing the surface to protect it from wear and tear. Acid-based stains and water-based stains are the two main types, each offering different color options and finishes.
