Our Deckorators grooved-edge deck boards work perfectly with Deckorators Stowaway™ hidden fasteners, providing a fastener-free look. These fasteners install between the grooved edges of deck boards, which eliminates the need for pre-drilling, automatically spaces deck boards with the appropriate gap, and makes installation quick and easy.

If traditional fastening through the top of the decking is preferred but a fastener-free appearance is still desired, Pro fastening systems are the fastest, easiest way to hide deck screw heads on stairs, on perimeter boards, or when replacing a deck board. For more information, view our Compatible Deck Fastener Information Sheet.

Yes, all Deckorators® decking requires consistent spacing between boards to allow for water runoff. However, the specific gapping requirements vary by product line due to differences in thermal expansion and contraction.

For Voyage Decking, Vault Decking, and Porch Flooring: Our patented Surestone™ Technology minimizes thermal expansion and contraction (approximately ¼" over a 20' board in extreme temperatures). This means end gapping is less critical, but consistent spacing is still recommended. Please refer to each product line's installation instructions for precise gapping guidelines.

For Vista and Venture Decking: Gapping at the ends and between boards is necessary to accommodate expansion and contraction. At the ends of the deck boards, allow a minimum of a 1/16" gap for every 20°F difference between the installation temperature and the hottest temperature expected. Additionally, allow a 1/4" gap between the deck boards and between all decking and any permanent structure or post for water runoff. Please refer to each product line's installation instructions for detailed gapping requirements based on the installation temperature.

Major fastener manufacturers produce screws made specifically for composite decking. The use of these screws will reduce the amount of pre-drilling and countersinking required. For ease of installation, we recommend using 2½" corrosion-resistant composite wood deck screws. These screws help minimize the common “mushroom” effect that sometimes occurs when using standard fasteners. We recommend the Stowaway™ hidden fastener. We recommend using broad-head stainless steel 2" nails with Fastendry. If traditional fastening through the top of the decking is preferred but a fastener-free appearance is still desired, Pro fastening systems are the fastest, easiest way to hide deck screw heads on stairs, on perimeter boards, or when replacing a deck board. For more information, refer to the installation instructions.
