Sanding pads are tools used in woodworking and finishing to smooth surfaces. They are typically made of a flexible backing material coated with abrasive particles, which help remove imperfections and prepare surfaces for painting or staining. Sanding pads come in various grits, indicating their coarseness, with lower numbers being rougher and higher numbers being finer. These pads can be used with hand sanders or power tools like orbital sanders. They are available in different shapes and sizes to fit various applications, making them versatile for tasks involving wood, metal, or plastic. Proper use of sanding pads can enhance the quality of the final finish.
