Cover, a board assembly and a method for protecting a board

A cover, a board assembly and a method for protecting a board are provided. In an embodiment, one or more boards are adjacent lengthwise, as in a floor of a deck or wall. A top portion of each of the boards is trimmed proximate to lengthwise edges. In an alternate embodiment, the boards are trimmed prior to assembly of the deck to create a groove along each of the edges. A cover, constructed from a wood/plastic composite, is placed on each of the boards. The cover extends across each of the boards' top surface and into the grooves created by trimming of the board. The cover may be secured to the board via an adhesive and/or a fastener and limits direct contact between the board and, for example, ultra-violet rays and/or precipitation. Accordingly, a deck utilizing one or more covers may be used for a prolonged period of time.
