    How do I clean my composite deck or rail?

    It’s important to keep leaves and other materials that can stain off your deck year-round. Sweep off the deck boards and make sure to clean out the spaces between the boards. We recommend using soap or detergent mixed with water to remove any marks or dirt from your deck boards. Power washers can be used to clean deck boards; however, a fan-tip nozzle on the lowest setting.

    Can Deckorators railing be used for structural applications?

    No. While Deckorators railing does provide superior surface integrity and strength, it’s not suitable for structural applications.

    How do varying weather conditions affect Deckorators railing during installation?

    Deckorators performs well in varying weather conditions. During installation, it will contract only slightly in cold weather. It expands in hot weather. We recommend that the material be on the job site 48 hours prior to installation to acclimate. Reference the Railing tab on the Installation Instructions page for spacing guidelines to ensure proper room for expansion and contraction.

    Do I need special tools to install Deckorators railing?

    Conventional tools for cutting, drilling, and nailing can be used with Deckorators railing. We recommend using a sharp carbide-tipped saw blade for cutting. For your safety, remember to wear protective clothing and safety glasses. Reference the Railing tab on the Installation Instructions page for railing instructions specific to each product line.
