What is the primary focus of SSPC-SP1 standards?

The primary focus of SSPC-SP1 standards is solvent cleaning. This standard outlines the procedures for cleaning surfaces to remove contaminants such as oil, grease, dirt, and other unwanted substances that can interfere with the adhesion of coatings. The main objective of solvent cleaning is to prepare the substrate adequately for further surface preparation processes or direct application of coatings.

Solvent cleaning is particularly important in ensuring that the surface is free of substances that may cause coating failure. This standard provides specific guidelines and practices to effectively use solvents, ensuring that the cleaning process is done in a manner that complies with safety and environmental regulations.

The other options, while also related to surface preparation, address different methods of cleaning and preparation techniques. Power tool cleaning, light blast cleaning, and hand tool cleaning are all important procedures within the broader context of surface preparation but do not specifically encapsulate the purpose and guidelines outlined in SSPC-SP1.
