If you are a do it yourself kind of person, chances are you have used sandpaper to smooth and polish various surfaces. You may or may not know that sandpaper is most likely not made of actually sand. To pick the best sandpaper for wood, for metal, for glass, for drywall, for aluminum, for spackle, for concrete, or to remove paint, you need deeper knowledge of what to look for. Hopefully, this article will provide you some proper insights. So let’s get down to the ‘gritty’ deals.

You can generally classify a piece of sandpaper based on abrasive material and grit size. You should also pay attention to the backing as it determines the flexibility. Stronger backings make it easier and faster for you to sand wood and other surfaces. They also wear the paper faster and produce a rougher sanded surface. On the other hand, a softer more flexible backing allows the sandpaper to follow contours better.

Picking the right abrasive material for sandpaper is also important. You should be aware of something called the Mohs Scale to define the hardness of a material. In this scale, 0 is the softest material and 10 is the hardest. Keep in mind that this scale is not linear. For example, diamond is a 10 while aluminum oxide is a 9. However, diamond is 4 times harder than aluminium oxide. Quartz is a 7 on the Mohs scale and is 4 times softer than aluminum oxide. In general, you should be using abrasive materials that are harder than the material being polished.

Finally, there is grit size which refers to to size of the individual particles. The size is actually inversely related to particle size so a smaller number of 20 to 60 means the average particle diameter is large. This translates to a extra coarse material that is very fast at removing material and great for initial sanding project. They are great for ripping off paint easily but you risk damaging the surface. Then you have medium grit from 60 to about 100, which is not too big and not too small. Finally, there is fine grit sandpaper, which runs 100+ grit count. These are small particles that are used after you have already made a first run. They are great for polishing down a surface.
