The process of removing unwanted coatings from hardened cementitious material is essential for maintaining aesthetics, preparing surfaces for recoating, and preventing potential damage. This action typically addresses a visual blemish or a compromised surface integrity.
Effective coating removal from these surfaces offers several advantages, including restoration of the original appearance, prevention of substrate degradation caused by trapped moisture or chemicals, and ensuring proper adhesion for subsequent applications. Historically, mechanical abrasion was the primary method; however, advancements have introduced chemical solutions and alternative physical techniques.
