Sandpaper is a tool used for removing material from a surface. It comes in a wide range of grit sizes and can be used for a number of different projects.
Each type of sandpaper has three important qualities: its coarseness, its abrasive material and its coating. The grit number on a piece of sandpaper reflects the number of holes per square inch in the screens used to sieve the grains during manufacture.

Micro
Micro sandpaper is used for sanding or polishing small, hard-to-reach areas. It is commonly used by artisans, woodturners and polymer clay bead jewellers. It can also be used by metalworkers and carpenters for sanding, removing paint and repairing scratches.
The grit grading system is important to understand, as it helps you select the right sandpaper for your project. Originally, many sandpapers were graded using the CAMI scale, but more recent abrasives use the FEPA grading system. You can tell this by looking for the letter P prefix on a sandpaper’s grit number or by checking the back of the paper.
Grit grading doesn’t just mean matching your abrasive to the job: It also refers to grit width and quality of the paper’s bonding resins and backings. Better-quality sandpapers have better bonding resins and backings, which are especially critical for machine-sanding. These also help hold the grit in place, so it doesn’t wear off the paper quickly or flake off in humid weather.
Typically, coarse sandpapers are used for rough sanding and fine-grit sandpapers are used for finishing. In general, a fine grit is the best choice for smoothing curved surfaces, while a coarse grit is good for sanding straight lines.
This sanding paper has a soft and flexible backing made of a non-woven fabric to which a resilient glue has been applied. This glue is designed to allow the crystals to penetrate far enough into the cushioning layer to cut, but not go so far as to come loose and scratch your surface.
The abrasive can be used wet or dry, and it is suitable for most standard cutting oils and honing oils. It can be used on most metals, plastics and a variety of other materials.
Macro
Different types of sandpaper are used for different jobs. If you're a woodworker, you use sandpaper to smooth and shape wooden objects; if you're a painter or refinisher, you need it to remove old finishes and polish new ones; and if you're a plumber, you might use it to clean your pipes and remove corrosion.
The grit of sandpaper is measured in gauge numbers from #24 all the way to #1,000. Higher grits are more rough and abrasive, while lower grits are finer and less abrasive.
Macro sandpaper is used to remove layers of varnish and paint from bare wood before it is refinished. These sandpapers are typically used on hardwood flooring, but can also be used to sand drywall and other materials.
There are a few different kinds of macro sandpaper, including flint sandpaper and emery sandpaper. Flint sandpaper is made from flint particles, while emery sandpaper uses synthetic materials.
Another type of sandpaper is nonwoven sandpaper. This kind of sandpaper is woven from a nonwoven fiber, such as cotton or polyester. It is very inexpensive and versatile, and it can be used for sanding a variety of surfaces.
