How to sand concrete with a random orbital sander?
A random orbital sander is the most effective and time-efficient tool for sanding concrete. It’s more convenient than using a traditional palm sander, which requires different strokes for left-to-right and back-to-front motion control.
The concrete should be gently smoothed down using power equipment like an angle grinder before you try the palm sanding method. Traditional hand sanders can be used in place of power tools for those of us without such conveniences, but they will take much longer to complete the task.
Follow the given instructions to sand concrete with a random orbital sander:
- Sanding concrete floors requires clearing the area of any obstructions.
- Wrap your doors, windows, and vents in plastic. This will aid you in keeping derbies and dust off of your walls.
- Mopping the floor is an essential part of keeping it clean. Mop it up and let it dry.
- The floor may be divided into sections so you can focus on one section at a time.
- Get sandpaper with grit between 30 and 60 and use it to buff the surface until it’s smooth. Get started in the corner and work your way up. It will be easier to track where you’ve sanded and in what order if you begin in a corner.
- Continue making vertical passes, allowing you to cover more ground in confined spaces. Each iteration of this strategy should halve the elapsed time of the preceding one.
- Sanding bumps require extreme caution at all times. Sand it down until it’s completely smooth. Make a couple of attempts at passing. Don’t just let the sander sit there doing nothing, or you won’t get a smooth finish.
- Fill any holes or uneven spots in the wall with epoxy glue and give it time to cure and smooth out.
- The place from where you began the first round of passes should be your starting point once again. Invert the steps so that you finish up back where you began.
- Proceed in a horizontal direction now. Check for at least two more sets to guarantee success.
- Use a vacuum cleaner or a moist towel to clean the floor thoroughly. A uniform coat of concrete sealer must now be applied.
- To get an even smoother finish, switch to sandpaper with grit between 80 and 120. It’s recommended that you do this process six to ten times.
- Do another thorough floor cleaning. Now, change to a more acceptable grit paper. Fine grits include those with numbers such as 240 or 320.
- The next step is to repeat steps 6–10 using more acceptable grit paper, and then you’re done with this section of the procedure. Keep going until you get to a grit of 1,500 or higher. Mopping can be used occasionally to get rid of accumulated dust and debris.
- Recheck the ground for the best results. One final mopping may be necessary to remove any remaining paint.
- The last step is to paint the floor if you feel it’s essential.

Sanding is the first stage in restoring cracked, chipped, or damaged concrete in or around your property. Additionally, you might try sanding the stain to see if it comes off. However, you should know a few things about the correct technique to sand concrete before you begin lunging at your concrete helter-skelter with sandpaper.
You should look professionally at any holes or cracks in your concrete foundation, porch, or other structure before you try to fix them by sanding them down. Repairing this damage won’t keep the concrete’s strength and may expose deeper issues that jeopardise your home’s structural integrity.
Sanding is the best option if your concrete surface is an appliance, such as a countertop or mantel. On the other hand, grinding could be the preferable choice if you’re trying to level and smooth a big slab surface, like a floor or patio.
In contrast to a sander, a grinder can produce a homogeneous texture and height over an enormous area. Use the same precautions while sanding concrete or another masonry as you would when working with wood.
Put on goggles made of protective plastic, and cover your mouth and nose with a disposable paper mask or a respirator, if you have access to either. Many individuals incorrectly believe that sanders are not very dangerous.
It’s essential to wear protective gloves while using any kind of electric tool, but mainly when using a sander, since it may cause serious injury to your hands and fingers if used improperly or at fast speeds. Keep your sander in its case and never disable its safety features.
Wear sturdy work gloves to protect your hands and keep your fingers out of the sander’s moving parts.
