Which cleaning process is indicated by SSPC-SP13?

SSPC-SP13 refers specifically to the cleaning process for concrete surfaces. This standard focuses on preparing concrete substrates for the application of protective coatings. The process outlined in SSPC-SP13 involves removing contaminants such as dirt, oils, and existing coatings to ensure that the surface is properly prepared for adhesion of new materials.

Understanding this standard is crucial for anyone involved in the surface preparation of concrete in industrial settings, as proper cleaning is vital for the effectiveness and longevity of the coatings applied afterward. Ensuring the surface is clean increases the performance of the protective system and minimizes issues such as blistering or peeling that may arise from inadequate surface preparation.

The other options pertain to different cleaning standards and methods used for various materials or levels of surface cleanliness, but none relate specifically to concrete preparation as defined in SSPC-SP13.
