About Woca Oil hardwood flooring finish. Contact us for pricing and information. Choose Woca Oil Wood Floor Finish An oil-finished floor provides the most natural look of any wood floor finish. An oil finish also tends to make hardwood floors look "old" as if they had been installed a very long time ago. Prior to the use of various urethane and similar finishes, oil was the traditional finish of choice. In Europe, where this traditional natural look has been in demand for quite some time, oil finishes account for most of all wood floor finishes.Since an oil finish actually penetrates and becomes a part of the surface of a hardwood floor, it is not nearly as sensitive to scratches and wear as a urethane finish. As it not only penetrates but also hardens, a Woca oil finish provides very good protection and is easy to maintain. If done properly, it will prevent a hardwood flooring from ever having to be sanded. Cleaners & Pretreatment Products Woca Oil also offer a complete line of products to prepare wood floors for finishing or refinishing. You need our pre-cleaner to prepare wood for lye treatment, oil finishing, re-oiling and/or the removal of stubborn stains. We have lye for pre-treatment of wood surfaces, antique lye for pre-treatment to darken many kinds of wood, and driftwood lye as a color pre-treatment for untreated wood. Our Pre-Color and Active Stain are both used for the color pre-treatment process.
