Forget what you saw in the 1970s: These days, indoor-outdoor carpet is more than just green turf. A large selection of colors and textures is available, and an intermediate-level do-it-yourselfer can tackle the installation in one day. You might have to rent a carpet-roller, but the tight seal it will provide will make it worth the minor expense.
Outdoor Carpets are designed for use on boats, decks, patios, porches, and any other outdoor area where you want something other than wood or concrete flooring. The yarn is specially treated to resist fading in direct sunlight, and the backing materials are formulated to resist damage from moisture.
