The most common types of orbital sanders are random orbital sanders and sheet sanders.
Random orbital sanders use circular sanding disks to spin in a random orbit and provide a smooth finish with no visible circular marks. Sheet sanders, on the other hand, use sanding sheets attached with clamps to a rectangular pad, making them perfect for sanding large flat surfaces. There are also finish sanders, which are smaller and used for fine finishing work, and palm sanders, which are handheld for detail sanding in tight spaces.
Understanding the different types of orbital sanders can help you make the most of your woodworking projects and achieve the results you desire.
Using an Orbital Sander on Concrete
Yes, you can use an orbital sander on concrete as long as you have the correct sanding pad and sandpaper.

When using an orbital sander on concrete, it’s crucial to wear protective gear, including goggles, a dust mask, and earplugs, as it can create a lot of dust and noise.
Furthermore, it is recommended to use the sander in a well-ventilated area, or outdoors, to prevent dust from being inhaled and to keep the work area clean. Prior to sanding, thoroughly clean the concrete surface to remove any debris or dirt. Finally, it’s essential to use the right sandpaper grit to avoid damaging the surface, and to work in a slow, controlled manner to achieve the desired finish.
Preparing the Concrete Surface
Preparing the concrete surface is a crucial step in the process of painting or coating your concrete. Using an orbital sander on concrete is an effective way of preparing the surface. An orbital sander uses a circular motion to sand the surface, which helps to remove any bumps, ridges, or rough spots.
To use an orbital sander, first, make sure the surface is clean and free of any debris. Then attach the sandpaper to the sander’s pad and turn on the machine. Gently move the sander back and forth across the surface, keeping the sander moving at all times to avoid any unevenness.
Be sure to wear protective gear, such as a dust mask and safety glasses, as sanding concrete can generate a lot of dust. An orbital sander can make preparing a concrete surface much easier and faster, leaving a smooth and even surface ready for painting or coating.
Choosing the Right Sandpaper Grit
When using an orbital sander on concrete, it’s important to select the right sandpaper grit for the task at hand. This will ensure that you achieve the desired level of smoothness and remove any imperfections. For initial rough sanding, a coarse grit such as 60 or 80 will work best.
As you move on to finer sanding, a medium grit such as 120 or 150 will be most effective. For a final smooth finish, a fine grit such as 220 or 240 should be used. Remember to always start with a coarser grit and move on to finer grits gradually.
By doing this, you’ll avoid damaging the concrete surface and achieve a professional and polished result.
Using the Orbital Sander on Concrete
Using an orbital sander on concrete may seem like an odd choice, but it can be an effective way to achieve a smooth finish on a concrete surface.
