Sanding Concrete If you have concrete that needs to be architecturally exposed, you can sand it by hand using wet and dry sandpaper or a belt sander. Once you have dried the concrete and still have a creamy concrete surface, it is best to wet hand sand with 320-400 sand / sandpaper. The good news is that concrete can be sanded relatively easily if you use the right equipment, such as good concrete paper.
If you only have a small area to sand, you can also use a palm sander, orbital sander or belt sander. For wide floor spaces, use a floor sander – also known as a drum sander or a concrete grinder. A belt sander is a sander used in shaping and finishing wood and other materials.
If you have any type of concrete surface, it can be smoothed with a concrete grinder to achieve the desired look using common concrete grinding techniques. If you’ve dry-sanded your concrete and still have a cement-cream finish, then the easiest thing to do is to wet sand by hand using 320 to 400 grit silicon-carbide wet/dry sandpaper. The good news is, you can achieve this smooth, glossy look for yourself AND you don’t have to outsource the job to tradesmen either! With a range of easy-to-operate concrete polishing equipment for rent, you can be the master of your own project on either old or new concrete floors.
