Sanding pads are tools used in woodworking and finishing to smooth surfaces. They come in various grits, which indicate the coarseness of the pad. Coarser grits are used for heavy material removal, while finer grits are ideal for achieving a smooth finish. Sanding pads can be made from different materials, including sandpaper, foam, and felt. These pads can be attached to power tools like orbital sanders or used manually. They are essential for preparing surfaces for painting, staining, or sealing. Proper use of sanding pads helps ensure a professional-looking result in various DIY and professional projects.
