Best Orbital Floor Sanders for Deck

If you exert no effort to protect your deck, the harsh outdoor elements and constant foot traffic can wear your deck over time, causing its original color to fade. Hence, you need to provide your deck with the necessary protection and coating. But before you can apply a protective layer to your deck, you must thoroughly clean and sand it using an electric sander like an orbital floor sander. 

Compared to the belt sander, the orbital floor sander is perfect for finishing work rather than rough work. Thus, you can use it for sanding hard-to-reach edges and corners of the deck. After using your belt sander, you can also utilize the orbital floor sander to give your deck a smoother sanding.
