With IRWIN sandpaper, you can get to work on every sanding job. The sanding mesh fits on delta sanders, sheet sanders, multi-sanders, random orbital sanders, and drywall sanders. You can choose the grit that suits your job. For example, sand old paint layers with K80 and new paint layers with K240 The mesh is strong and washable, so you can use it more often than sandpaper. The mesh also removes dust better, so you can work for longer. You can stick the sandpaper easily and quickly to the sander with velcro.
