WHY SURFACE PREPARATION IS IMPORTANT

Coatings experts often say that surface preparation is the most important part of a coating system. By this they mean that surface preparation affects the performance of the coating more than any other variable. Surface preparation is to a coating system what a foundation is to a building. Surface preparation is important in two ways: mechanically, by providing an anchor for the coating and chemically, by allowing intimate contact of coating molecules with the steel or concrete surface. To make sure that a coating system will provided the highest level of protection to steel of concrete surfaces, the surface must be roughened for the best mechanical adhesion and the surface must be cleared and cleaned of all debris so that the coating contacts the surface. With the proper preparation, a coating system will provide many years of service.
