  • FAQs
    ​Why don’t I see a repeating pattern on Fiberon Concordia Symmetry Collection boards like I do with some other decking?

    The Symmetry Collection is manufactured to have more random, natural graining than you’ll find with other deck boards. There are no visible repeats or easy-to-discern patterns.

    ​How do I clean Symmetry Decking?

    For general cleaning, use soap and water or mild household cleaners.

    How much ventilation is required under a deck?

    It is very important that there be adequate and unobstructed air flow under the deck to prevent excessive water absorption. Improve drainage or grade flat areas where standing water may gather. For decks with limited ventilation, six inches of clear ventilation is required.

    What if my decking gets scratched?

    In the same way that wood decking materials can get marred or gouged, the surface of composite decking can also be scratched. Horizon Decking and ProTect Advantage are the Fiberon products most resistant to scratches. If scratches do occur, we recommend allowing normal wear marks to disappear gradually.
