According to SSPC-SP1, what cleaning method is specified?

SSPC-SP1 defines the standard for solvent cleaning, which is the process used to remove contaminants such as grease, oil, dirt, and other foreign substances from surfaces prior to the application of coatings. This method is crucial in ensuring that the substrate is adequately prepared, as any residue can hinder the adhesion of coatings and impact their performance.

Solvent cleaning is particularly effective for removing specific types of contaminants, especially those that cannot be effectively addressed through mechanical methods. Its application often involves the use of various solvents or solvent-based cleaning agents, which are applied through methods such as wiping or brushing to dissolve and remove contaminants.

Understanding the importance of this cleaning method within the context of surface preparation emphasizes the necessity of ensuring a clean and conducive surface for coating application, as specified in the SSPC-SP1 standard. This preparation is vital for achieving desired coating performance and longevity.
