Sanding Abrasives

There are several types of sandpaper available for purchase within the abrasives market. They are all designed for different sanding needs, stages, and effects. Using the proper type of abrasive is the key component to achieving the best quality finish for your sanding project. Projects that require manual sanding are best implemented using an aluminum oxide sandpaper. These projects usually involve sandpaper sheets and sanding blocks. Aluminum oxide paper is also effective for metal and wood sanding projects.

For projects that involve using motorized equipment, like a sanding belt, ceramic sandpaper is the right choice. For joint compounds, metals, and plastics that required smoothing, silicon carbide sandpaper is the appropriate type of abrasive to use. It’s also best for projects that require sanding between paint and finishes. However, silicon carbide is not appropriate for wood sanding and should never be used on anything with wood material. Its material is too harsh and sharp for sanding wood.

Grades of Sandpaper

Along with a large selection of sandpaper types, there are many different grades as well. The type of grade depends on the type of sanding project, material, and desired finish. And just like sandpaper types, it is equally important to match the appropriate grade of sandpaper for your project. The grade of sandpaper is measured by its “grit” or coarseness. The higher the grit, the finer the grade. There are three basic grades of sandpaper, all of which retain separate grit counts. They are displayed below:

Course Grade - 40 to 60 Grit
Medium Grade – 80 to 120 Grit
Fine Grade – 150 to 180 Grit

Not only is it important to use the proper types and grades of sanding paper for your project in queue, it is also vital to use the proper techniques and methods. For example, always sand in the same direction to get an even and smooth finish. This is an area where it is important to take your time and not rush. Wood should always be sanded along its grain, using even pressure on every stroke, and excessive sawdust should be wiped away as often as possible.
