What are the best methods to prevent filiform corrosion on painted aluminum outdoor sculptures?
Filiform corrosion is a common issue for painted aluminum outdoor sculptures, but it can be effectively prevented with the right methods. Start by ensuring proper surface preparation before painting, including thorough cleaning and the use of a suitable primer. Applying a high-quality, corrosion-resistant topcoat is essential to create a barrier against moisture and environmental contaminants. Regular maintenance, such as cleaning and inspecting for scratches or chips, helps address early signs of damage. Additionally, using sacrificial anodes or corrosion inhibitors can provide extra protection. By following these steps, you can significantly extend the lifespan and appearance of your aluminum sculptures.
