Staining is only one part of the hardwood floor refinishing process, but it can have the biggest impact on the appearance of your floors. Staining is an excellent way to change the look of hardwood flooring without losing the natural beauty and character of the wood floors. When considering refinishing your floors, you may decide to restore them back to their natural state. In that case no stain would be needed since the sanding and finish coats will make your floors as good as new. In other cases staining is essential in order to drastically change the aesthetic feel in your home.
