In terms of paint removal, what is a significant characteristic of sanding?

Sanding is characterized by its use of abrasive action, which means it physically removes paint from a surface by wearing it away. This method involves using a material such as sandpaper, which is coated with granules that are hard enough to abrade the paint when rubbed against the painted surface. The effectiveness of sanding comes from the mechanical means of removing layers of paint, including old finishes, allowing for a clean surface that is ready for refinishing.

In contrast to other methods of paint removal, sanding can be very effective for achieving a smooth and even surface, especially on flat areas. It is often used as part of surface preparation in both automotive and furniture refinishing projects. Other methods, such as chemical strippers or heat guns, vary in their approach but do not rely on abrasive action in the same way that sanding does. The physical removal of paint through abrasion is what makes sanding a distinct and commonly utilized technique in the painting and refinishing process.
