When the stain has dried, you may decide to make the color of the item darker. Do not hesitate and apply the stain again over the first coat. Follow above-shown steps once again. And then again, let it dry fully and then go to another step. When you’re finally satisfied with the result of hardwood staining, it means that the time for applying finishing coat has come. Remember: oil-based wood finish to oil-based stain, water-based finish to water-based stain. You may use clear coat polyurethane as a finish.
