Surface finishes are very popular because they are durable, water-resistant and require minimal maintenance. Surface finishes are blends of synthetic resins. These finishes are most often referred to as urethanes or polyurethanes, and remain on the surface of the wood to form a protective coating. They generally are available in gloss, semi-gloss, and satin. For cleaning, you should use the manufacturer's recommended cleaning products. Or, you can use a generic hardwood floor cleaner. You should never use wax-based on a surface finish. In addition, petroleum-based cleaners should be avoided on water-based finishes.
