Surface Preparation Before Coating | ISO 8501 & SSPC Standards Explained | QA/QC Guide

Surface Preparation before Coating is the most critical step for achieving long-lasting and high-quality coating performance. In this video, we explain the importance of proper surface preparation according to international standards like ISO 8501 and SSPC. You will learn about different surface cleaning methods such as Degreasing, Mechanical Cleaning, and Abrasive Blasting. We also explain ISO grades (Sa 1, Sa 2, Sa 2.5, Sa 3) and their SSPC equivalents (SP-7, SP-6, SP-10, SP-5) in a simple and practical way. This video is very helpful for QA/QC inspectors, coating engineers, and anyone working in oil & gas, pipelines, and industrial projects.
