What is the only approved method for removing paint from composite laminate/structure?

The most effective way to remove paint from composite laminate and structures is through sanding. This method allows for a controlled removal of the paint without damaging the underlying composite materials. Sanding smooths the surface and ensures that the composite's integrity remains intact, as it does not involve the use of potentially harmful chemicals that could compromise the structure or performance of the materials.

Chemical strippers, while effective on metals, can degrade composite structures, which are sensitive to certain chemicals and can lose their mechanical properties. Scrubbing with water may not effectively remove paint, especially if it is well-adhered or multiple layers are present. High-pressure washing can also lead to structural damage by forcing water into laminate seams or creating delamination.

Thus, sanding stands out as the only approved and safe method for maintaining the integrity of composite structures while effectively removing paint.
