Choosing the Right Sandpaper Grit

When fitting sandpaper to your orbital sander, it’s essential to choose the right grit for your specific project. The grit refers to the coarseness of the sandpaper and determines how aggressive the sanding action will be.

The following are some general guidelines for selecting the appropriate sandpaper grit:

1. Coarse Grits (40-60)

Coarse grit sandpaper is typically used for heavy-duty sanding or removing a significant amount of material quickly. This grit is perfect for removing old paint or varnish, leveling rough wood surfaces, or smoothing out rough patches on a project.

2. Medium Grits (80-120)

Medium grit sandpaper is ideal for general-purpose sanding tasks. It can be used for smoothing out rough edges, removing light scratches, preparing surfaces for painting or staining, and achieving a smooth finish without removing too much material.

3. Fine Grits (150-180)

Fine grit sandpaper is suitable for finishing touches and achieving a smooth, polished surface. It is commonly used for sanding between coats of paint or varnish to remove imperfections, smoothing wood grain, and preparing surfaces for the final finish.

4. Very Fine Grits (220+)

Very fine grit sandpaper is used for delicate sanding tasks and creating a polished, refined surface. It is commonly used for sanding between coats of finish, achieving a high-gloss surface, or preparing surfaces for intricate detailing.

It’s essential to keep in mind that the specific project you are working on may require different grits for different stages, so it’s always a good idea to have a range of sandpaper grits available.
