Which method is used to remove paint from large metal areas?

The method of blasting with plastic media is particularly effective for removing paint from large metal surfaces. This technique utilizes small plastic particles that are propelled at high velocity to strip away paint without damaging the underlying metal. It is less abrasive than some other methods, allowing for the preservation of the substrate, which is crucial when dealing with sensitive or specific types of metals that may be harmed by harsher methods.

Balancing effectiveness and surface preservation, plastic media blasting is often preferred for large areas where extensive coating removal is necessary. It provides a uniform and efficient cleaning process, making it ideal for aviation applications where metal integrity is critical.

Other methods may have limitations, such as sandblasting, which can be overly harsh on certain materials and lead to surface distortion. Hand scraping is labor-intensive and not practical for large areas. Chemical strippers can also be effective but may introduce harmful residues and require careful handling and cleanup, especially in an aviation context where precision is paramount. Thus, blasting with plastic media is the optimal choice for such tasks.
