Sanding concrete is possible, although regular sandpaper won’t be enough to complete the job. Ceramic and aluminum oxide can help create a smooth finish, but it will require a longer amount of time and more effort. If you’re looking for a better way to sand your concrete surface, consider using diamond sanding or polishing pads. These tools are specifically designed for the task and have many advantages that make the process simpler and more efficient. Moreover, they can often achieve a higher quality of finish compared to other options available.
