In addition to waterproofing your cabinets, you can refinish your floors with polyurethane. Polyurethane works well on both countertops and wood floors. Simply follow the exact instructions as you would with your cabinets. Wash your floors thoroughly, paying attention to any cracks or neglected spaces. Make sure that all the grit is gone, and let them completely dry before applying the polyurethane.  Although it’s challenging to stay out of the kitchen for several hours, it’s essential to make sure that the floors are fully dry. Otherwise, you’ll just need to reapply.
