You can refinish wood furniture by sanding it down to the bare wood, then staining and sealing it with a protective finish. First, remove all the hardware from the piece of furniture you're refinishing. Then, use a medium-grit sandpaper to sand down the surface of the wood, being careful not to damage the underlying wood. Next, stain the wood using a brush or cloth, and let it dry for 24 hours. Finally, seal the wood with a protective finish using a brush or cloth. Let it dry for 24 hours before reinstalling the hardware.

1. Remove the old finish with a stripping agent. 2. Sand the surface smooth. 3. Apply a new finish. To remove the old finish, you can use a chemical stripping agent or heat it with a blowtorch. Be careful not to damage the wood while removing the finish. Once the old finish is removed, sand the surface of the wood until it's smooth. You can use different grades of sandpaper, depending on how much work needs to be done. Finally, apply a new finish to protect and enhance the look of your furniture. There are many types of finishes available, so choose one that will best suit your needs.
