- SSPC surface protection standards
- Pretreatment methods for recoating painted and galvanized surfaces
Overview
The objective of surface preparation prior to applying a coating system is to create proper adhesion of the coating to the underlying substrate. Proper adhesion will occur if a suitable level of surface cleanliness and roughness (profile) is achieved. There are a wide variety of surface preparation methods available, such as solvent cleaning, power-tool cleaning and abrasive blast cleaning. The method chosen depends on many factors, including the desired cleanliness and anchor profile, the substrate material, ease of accessibility to the work surface and worker safety and environmental considerations.
The importance of surface preparation cannot be overemphasized. It is the foundation upon which a coating system is laid. Without suitable substrate cleanliness and anchor profile, the best coating system will quickly fail due to lack of adhesion.
In this course, the student will learn about the types of surface preparation methods used for industrial coating systems.
Specific Knowledge or Skill Obtained
This course teaches the following specific knowledge and skills:
- The impact of surface cleanliness and profile on adhesion of coating systems
