Remove old glue from the table. Simply rub the area with a vinegar-dampened cloth. Rub until all the old repair glue is gone. Allow the area to dry completely before continuing — about 30 minutes to an hour.
Scoop up a small amount of wood filler with a cuticle orange stick. Use a plastic spatula, if filling a larger crack. Poke the filler into the crack and smooth it across the surface of the crack.
Wipe away excess filler with a cloth. Allow the wood filler to cure for two to three hours or according to the package directions.
Sand the surface of the table using fine 150-grade sandpaper. Rub away excess glue to leave a smooth finish.
Finish the treatment with an oil- or wax-based product. Rub the entire surface of the table with a soft cheesecloth for optimum shine.
