There are four types of sandpaper – each designed for a different purpose:
1. Coarse sandpaper: This is the coarsest type of sandpaper and is typically used for removing paint, varnish or other finishes from wood.
2. Medium sandpaper: This is a versatile type of sandpaper that can be used for sanding wood, metal or plastic.
3. Fine sandpaper: This is the finest type of sandpaper and is typically used for finishing work on wood or metal.
4. Ultra-fine sandpaper: This is the finest type of sandpaper available and is typically used for polishing metals or plastics.
