What does SSPC-SP 2 focus on?

SSPC-SP 2 specifically addresses the process of removing loose surface contaminants from steel surfaces through hand and power tool cleaning. This level of preparation aims to ensure that any rust, loose paint, or debris is effectively cleaned off the surface before the application of coatings. By focusing on this aspect, SSPC-SP 2 plays a critical role in creating an optimal substrate for paint adhesion and ensuring the durability and effectiveness of the protective coatings.

The other options cover different topics or procedures not encapsulated by SSPC-SP 2. For instance, solvent cleaning procedures fall under a different standard and do not specifically relate to the manual or power-tool methods intended by SSPC-SP 2. Similarly, alternative surface preparation methods would refer to practices outside the hand and power tool cleaning spectrum that SSPC-SP 2 specifically dictates. Testing adhesive properties is unrelated to surface preparation and instead pertains to evaluating the bond strength of coatings to a substrate.
