Sanding is inherent to woodworking and is a vital need to ensure the surface of your wood sign is smooth. It is also important for stains, sealer, and appearance. There are many types of sandpaper and quite honestly be a little confusing from the wood sign perspective.

When I started I didn’t know very much about finishing wood signs. But over time I have refined my sandpaper needs and I’m not buying sandpaper I don’t need.

Below I have listed my top picks for sandpaper. There are three categories. They are for the orbital sander, sanding blocks, and palm sander. Each of these will need different shapes and different grits.

Top Orbital Sander – Sand Paper

Diablo hands down is the best brand of sandpaper. I have used several different brands and generic brands and I keep returning to Diablo.

Top Sanding Blocks

Sanding blocks allow you to sand the surface and get into those areas where it is very difficult to sand. Additionally, it allows you to be able to grip the sanding block. Sometimes it is very hard to hold onto the sandpaper when you are trying to get into those hard areas to sand.
