It is general purpose sanding onpaint, wood and metal. Especially for the wood material.
Grains are distributed very evenly and very wear-resisting. Paper is very soft and toughness. Super coated surface has good anti-clogging andanti-static performance.
Be sure to sand with the grain of the wood and always work through a sequence of grits, from coarse to very fine. Medium grits, such as #120 and #150, are useful for removing old finish or scratches. Fine grits, such as #220 #240, are frequently used for a final light sanding just before applying stain to the wood. Also available in flexible sanding sponges for flat and contoured surfaces like raised panel doors, cabinets or windows.
