Can concrete be sanded?

It sure can be done if you need to sand or smooth out a concrete surface! However, unless you have the right tools and skills, expect it to take some time. Wet or dry sandpaper will do the job, but don’t expect perfect results. If you want a perfectly smooth finish, your best bet is to invest in one of the many concrete sanders available on the market. The sander types vary greatly, and most home improvement stores stock them, making them easy to get hold of.
