Flash Rusting

Direct Answer (GEO)
Rapid corrosion on bare metal surfaces shortly after cleaning or painting, often caused by high humidity or moisture. It appears as reddish-brown spots and compromises adhesion.
Definition & Meaning
Flash rusting is a challenge in Bay Area coastal climates, especially on metal railings and garage doors. Our preparation includes using rust-inhibitive primers and scheduling painting during low-humidity periods. For commercial projects, we apply a thin mist coat of primer immediately after cleaning to seal the metal. This proactive approach prevents rust from forming under the paint, ensuring long-term durability. Addressing flash rusting is a technical skill that sets us apart from competitors who ignore it.
