When working with concrete, it’s important to have the right sandpaper for the job. Concrete is a tough and durable material, but it can be difficult to sand due to its rough surface and hardness. Sandpaper that is too coarse can cause scratches and marks on the surface, while sandpaper that is too fine may not effectively remove rough spots and imperfections.
Here are some tips on what sandpaper to use on concrete:
1. Coarse Grit Sandpaper: If you need to remove a lot of material from the surface of your concrete, such as rough spots or old paint, start with coarse grit sandpaper. Typically, a 40 to 60-grit sandpaper is recommended for this type of work. This grit range will effectively remove material and smooth the surface, but be cautious as it may leave deep scratches that will require further sanding to remove.
2. Medium Grit Sandpaper: Once you have removed the rough spots and imperfections, you can move to medium grit sandpaper to smooth out the surface. An 80 to 120-grit sandpaper will help to further smooth out the surface and remove any remaining rough spots. This is also the recommended grit range for removing surface stains or sealers on concrete.

3. Fine Grit Sandpaper: If you want to achieve a smooth and polished finish on your concrete surface, fine-grit sandpaper is the way to go. Typically, 220-grit sandpaper or higher is recommended for this type of work. The fine-grit sandpaper will help to polish the surface and remove any remaining scratches or marks.
When sanding concrete, it is important to use sandpaper with a hard abrasive mineral, such as silicon carbide or diamond. These materials are strong enough to remove the hard and rough surface of the concrete.
It is also important to use proper safety equipment when sanding concrete, such as goggles, a dust mask, and gloves. Concrete dust can be harmful if inhaled, so make sure to take the necessary precautions.
In conclusion, when sanding concrete, start with coarse grit sandpaper to remove rough spots and imperfections, then move to medium grit sandpaper to smooth out the surface, and finish with fine-grit sandpaper to achieve a smooth and polished finish. Use sandpaper with a hard abrasive mineral, and be sure to wear the proper safety equipment to protect yourself from dust and debris.
