The nylon open mesh design allows sanding dust and debris to pass through, reducing clogging while the dual sided grit doubles the life of the sheet, simply turn it over and you have a brand-new sheet to sand with. This waterproof screen can also be rinsed with water and reused, extending the life of the screen.
