Begin with some of the most frequently asked questions about sandpaper. It is highly possible that you will find a few of your own questions listed below!

What is Sandpaper Made Of?

Sandpaper is a type of coated abrasive that is made up of various size granules adhered to a cloth or paper backing. The granules can consist of a variety of materials, mostly aluminum oxide or silicon carbide, but sometimes emery, garnet, zirconia alumina, and ceramic alumina are used. Sand and glass are no longer used to manufacture sandpaper.

What is Grit Size?

As mentioned, sandpaper is made up of various size granules. The finer the granules, the higher the grit count; the larger the granules, the courser the grit and the lower the grit count. The grit size you need depends on the application, whether you need to smooth and finish, roughen, or shape. Grit sizes can range from as low as 20, all the way up to 2000 or more.

Which Sandpaper Do I Use?

The grit and type of sandpaper you need to use depends on the intended application. For starters, if you are working with wood, stick with a silicon carbide based sandpaper. If you are working with metal, use an aluminum oxide based sandpaper. Furthermore, if you are simply finishing or smoothing, you want to use an extra fine abrasive; something below 100 grit. If you are removing material, such as paint, varnish, or uneven blemishes, stay between 120 and 150 grit sizes. If you are shaping or evening out un-leveled surfaces, you want to use a course grit of at least 200.

What is Wet Sanding?

Wet sanding is necessary when you are trying to achieve an extra glossy finish and an even surface, such as with automotive painting or guitar polishing. It is generally applied after the dry sanding phase, and involves using a mild lubricant (usually soapy water or mineral spirits) to smooth out surfaces between coats.
