If you are having issues when sanding a plywood, like having a hard time with dark spots in the wood grain, try using a wood putty before and sand it after. Another good idea would be to get a higher grade plywood to reduce the time needed to sand your piece of wood. Sanding can be performed by hand, block or random-orbit sander tool. The last method is the fastest but be cautious as working with hand compared to an electric device won’t give you the same feeling for pressure applied to wood.
