ISO Standard document based surface preparation is vital for corrosion control:

• Predictable performance: Standards define preparation quality so that a specified coating system reaches its intended lifetime
• Reproducibility and inspection: Everyone – owner, contractor, inspector – uses the same reference pictures and test methods, minimizing disputes
• Risk reduction: Proper removal of rust, mill scale, dust and especially soluble salts reduces premature failures like blistering, underfilm corrosion and delamination
• Life-cycle cost (LCC) efficiency: Correct surface preparation is less costly than early recoating, downtime, or structural repairs later in the asset’s life
