How long does fire retardant paint last on different surfaces?

The lifespan of fire retardant paint depends on the surface, environmental conditions, and maintenance. On wood, it can last 5-10 years, while on metal and concrete, it can be effective for over a decade. High humidity, extreme temperatures, or mechanical wear may reduce its durability. Regular inspections and reapplications as per manufacturer guidelines help maintain its protective properties. For optimal results, choosing a high-quality fire retardant paint and applying it correctly ensures long-term fire protection across various surfaces.
