This standard describes how to determine the pH value of a concrete surface after it has been chemically cleaned or etched. Cleaning and etching processes are often used for surface preparation of concrete, but if chemical residues are not completely removed, they may affect the adhesion and performance of the coating. By measuring the pH value of the surface after the final rinse, the impact of residual chemicals can be assessed to ensure that the concrete surface is suitable for coating operations.
