Has plastic coating which is not securely nor smoothly attached to the wood. Description states, "These panels come with a smooth layer of vinyl finish that renders an enriched and luxurious color quality." The vinyl finish is not smooth, as it does not wrap tightly around the slats. Also, the vinyl protrudes into the mounting groove, making it impossible to get a tight fit between the tongue and the groove. The dimensions are described as being 6" wide; however, the board only measures 5-5/8" from the tip of the tongue to the interior of the groove (overall board width only 5-7/8"). It would be problematic to install these, especially on a ceiling, without using nails, but due to the vinyl finish, it would be very difficult to hide the nail heads.
