When performing corrosion control on painted surfaces, what steps precede applying a corrosion inhibitor?

• A. Apply corrosion inhibitor before removing loose paint.
• B. Remove loose paint and corrosion, then apply inhibitor.
• C. Clean with solvent and degreaser, rinse, dry.
• D. Remove loose paint and corrosion, clean with solvent/degreaser, rinse, dry; then apply inhibitor as per manufacturer.

Answer: (D)

Proper surface preparation is essential before applying a corrosion inhibitor. Start by removing loose paint and any flaky corrosion so the surface is clean and receptive rather than sealing in corrosion under debris. Then clean with a solvent or degreaser to eliminate oils, greases, waxes, and other contaminants that could prevent the inhibitor from bonding. Rinse to remove solvent residues and dry thoroughly. Only after the surface is clean and dry should you apply the inhibitor, following the manufacturer’s instructions for application method, coverage, and drying times. Skipping these steps or applying the inhibitor to a dirty or damp surface can reduce its effectiveness and allow corrosion to continue.
