Concrete Acid Wash (Acid Etching) is a surface preparation and decorative technique used on concrete floors to clean, open the pores of the concrete, and enhance adhesion for coatings like epoxy. The process involves applying a mild acid solution to the concrete, which reacts with the surface to remove laitance, light contaminants, and mineral buildup. This creates a slightly textured profile that allows epoxy, sealers, or stains to bond more effectively.
In addition to preparation, an acid wash can also create subtle visual variation in the concrete, highlighting natural texture and character. It’s commonly used on garage floors, basements, patios, and commercial spaces as a cost-effective way to refresh concrete before applying epoxy or protective coatings.
Results vary based on the condition and age of the concrete, and proper neutralization and rinsing are essential to ensure long-term coating performance.
