Surfaces are often painted or coated to protect them against corrosion and degradation. Metal corrosion is of particular concern because it can cause equipment failures, which can lead to safety problems, environmental issues, lost production, and increased costs. Wood surfaces are also often painted or coated to provide protection from insects, fungi, and weathering. Paints and coatings for use on masonry surfaces must be formulated for the high pH levels that are often present. Prior to painting or coating, surfaces must be properly prepared, which may include cleaning, sanding, drying, and sometimes priming, in order to achieve even coverage and good adhesion. 

Learning Objectives

• Describe metal corrosion and how it can be prevented
• List and describe the main ingredients in paint
• List and describe the chemicals that can be used to clean metal surfaces prior to painting or coating
• Identify the main causes of wood degradation
• Describe the treatments and coatings that can be used to protect wood surfaces
• Explain how primers and paints for masonry surfaces are unique
• Describe common application methods for paints and coatings
• Identify the safety hazards presented by cleaning solvents, acid cleaners, soaps, detergents, and solvent-based and oil-based paints and coatings
