Spray the stained table with a wood cleaner spray. Wipe it down with soft cloths. Allow it to air dry for 20 minutes.
Press a piece of 100-grit sandpaper onto the bottom of an electric sander. Run the sander across the surface of the table, removing a top coat of sealer and opening up the wood grain to receive the new finish. Repeat with 220-grit sandpaper.
Wipe down the table with a tack cloth to swab off all the dust from sanding. Dip the 3-inch paintbrush in your can of stain and add a thick coat to the entire surface area of the table. Select a color like ebony, deep cherry or mahogany. Allow the stain to soak into the wood grain for 20 to 25 minutes and then wipe off the excess with a lint-free cloth. Repeat this process two more times.
Coat the wood table in a light coat of clear polyurethane to seal the wood and protect it. Allow this final coat 24 hours to dry.
