Coatings - Surface Preparation
Edward Brunet, Jr., P.E.
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 study the
types of surface preparation methods used for industrial coating systems. The course will cover Chapter
7, "Surface Preparation" in
the US Army Corps of Engineers document EM 1110-2-3400, "Painting: New
Construction and Maintenance".
The student must take a
multiple-choice quiz consisting of eighteen questions at the end of
this course to obtain PDH credits.
