1. Basics: What Are Cloth‑Backed and Paper‑Backed Sandpaper? Cloth‑backed sandpaper Uses fabric (cotton or synthetic cloth) as the backing instead of paper. Very flexible and tear‑resistant, lasts longer than regular paper sandpaper. Often sold as shop rolls (e.g. 100mm x 5m rolls you tear by hand). Paper‑backed sandpaper Uses different weights of paper as the backing. Common formats: sheets, discs, belts for random orbital sanders etc. Cheaper and good for large, flat surfaces, but tears and creases more easily. 2.
