POSSIBLE CAUSE

  • Steel in contact with air and moisture will rust (e.g., nails, steel railings, damaged galvanized, flashing, etc.).
  • Steel nails may develop black discoloration when in contact with damp wood that possesses a high amount of tannic acid.

SOLUTION

  • Prime bare steel as soon as possible with a rust-inhibiting primer or finish.
  • Replace steel nails with galvanized or other non-rusting nails.
  • Rusted nails that cannot be removed must be sanded to shiny metal; countersunk; coated with a rust-preventive primer; and then caulked, filled, or patched; and topcoated.
