The 3 most commonly used
wood floor finishing systems are:
Penetrating and hardening wood floor oils
Oil finishes currently used in the U.S. are primarily tung oil based or similar. These oils, while they do penetrate and dry, do not harden and will not provide the best protection against wear and stains. The European style oil finish provided by WOCA of Denmark will both penetrate and harden to achieve a very wear resistant finish, which is easily applied and maintained. This type of oil finish has been manufactured in Europe for over 30 years and is currently used on almost a third of all wood floors sold in Europe.
