The process of eliminating coatings from hardened cementitious material is a common requirement in building restoration, renovation, and surface preparation. This activity aims to extract unwanted layers, often for aesthetic improvement, surface repair, or to apply new treatments effectively.
Effective coating removal ensures proper adhesion of subsequent applications, prevents deterioration caused by trapped moisture or incompatible materials, and can reveal the original character of the concrete. Historically, abrasive techniques and chemical treatments were the primary options; modern technologies offer a wider range of solutions tailored to the specific coating type and concrete substrate.
