Abstract: A cover for boards of a wooden deck structure is made of flexible material and is preferably made from polyvinylchloride. The cover has a central portion with side portions that are integral therewith and can pivot relative to the central portion from a first position that is substantially parallel to the central portion to a second position that is substantially perpendicular to the central portion. The cover can be formed into rolls of significant length and can be installed by cutting an appropriate length from the roll to completely cover a single board from end to end. No adhesives or fastening means are required. A combination of a cover and wooden deck structure, and a method of installation of the cover on a deck structure is also provided. Each board of the deck is covered individually.
