Extra coarse sandpaper is designed for those who want to achieve material removal promptly with minimal effort. A grit size of 40 to 60 is perfect for the initial stages of sanding and for rough contouring. It works best in aggressive cutting applications such as removing old paint, smoothing rough surfaces or preparing surfaces for finishing. Our sandpaper is tough and has a rigid backing which does not permit it to fall apart during tough jobs so it is ideal for professionals and even hobbyists.
