Is there any finish available with UV protection for outdoor flooring?
Michael Dresdner: As far as I know, there is no finish made specifically for outdoor flooring other than deck coatings, which often contain UV absorbers. However, some UV-stable oil-based coatings, such as Waterlox®, are approved for both indoor and outdoor use. That means the sunlight won’t harm the finish, but does not imply the finish will prevent the wood from changing color due to the UV rays.
