Corrosionpedia Explains Substrate Preparation

Substrate preparation ensures the readiness of a material's surface to receive and support a protective coating. This preparation involves several activities depending on the material's type and application. Some key activities include chemical cleaning, mechanical cleaning, shot blasting, sand basting and acid etching, among others. The majority of such activities involve smoothing the material's surface to ensure debris is entirely removed and acquire the proper surface profile. Several industry standards must be closely followed to perform these activities correctly and ensure safety.
