PREPARATION OF STEEL SUBSTRATES BEFORE APPLICATION OF COATINGS AND RELATED MATERIALS

Characteristics of protective coatings and similar materials which are applied on steel greatly depend on the steel surface condition immediately before application. The main factors that affect these characteristics are:

• The presence of rust and mill scale;
• The presence on surface contaminants, including salts, dust, oil and grease;
• The surface profile.
