Therefore, it should be used with water. If you take water and sandpaper and polish it, polish it. It will stay in the sand gap, allowing the sandpaper on the surface to achieve its original effect. Dry sandpaper is not so troublesome. The larger the gap between the sand, the larger the sand will be, so there is no need to use water. Because during the grinding process, it will fall off due to the large gap.
