Troubleshooting Common Issues with Fluorocarbon Coated Aluminum

Fluorocarbon-coated aluminum (FCA) is a durable material often used in architectural applications due to its resistance to weather, corrosion, and fading. However, like any material, FCA can encounter problems that require troubleshooting. Here are some common issues and their solutions:

Discoloration or Chalking


– Improper cleaning methods

– Exposure to harsh chemicals or cleaning agents

– Ultraviolet light degradation

– Contaminants in the coating


– Use approved cleaning methods and detergents.

– Avoid using abrasive cleaners or harsh chemicals.

– Apply protective coatings or sealants to prevent UV damage.

– Clean the surface regularly to remove contaminants.

Cracking or Blistering


– Improper installation or handling

– Thermal expansion or contraction

– Excessive stress on the coating

– Moisture penetration


– Ensure proper installation techniques and avoid excessive force.

– Allow for thermal expansion and contraction by providing sufficient spacing.

– Minimize stress on the coating by using appropriate fasteners.

– Seal seams and edges to prevent moisture ingress.



– Insufficient coating thickness

– Scratches or damage to the coating

– Exposure to corrosive environments

– Poor ventilation


– Specify adequate coating thickness based on the intended application.

– Repair scratches or damage promptly to prevent corrosion initiation.

– Use FCA in environments suitable for its corrosion resistance.

– Provide adequate ventilation to prevent condensation and moisture buildup.

Fading or Loss of Gloss


– Prolonged exposure to sunlight

– Improper cleaning techniques

– Use of abrasive cleaners or polishes

– Environmental pollutants


– Apply protective coatings or sealants that provide UV protection.

– Use gentle cleaning methods and avoid harsh detergents.

– Avoid using abrasive cleaners or polishes that can damage the finish.

– Clean the surface regularly to remove pollutants and debris.


Troubleshooting common issues with FCA involves identifying the underlying causes and implementing appropriate solutions. By addressing these issues promptly, architects and contractors can ensure the long-term performance and aesthetic appeal of FCA in architectural applications.
