The ExoDek QuickClip Installation Guide for Accoya (2024 PDF) provides detailed instructions for installing Accoya® and Accoya Color Grey decking using the ExoDek QuickClip™ hidden-fastener system. This guide outlines groove requirements, fastener specifications, airflow needs, butt-joint layouts, joist preparation, and installation steps for a stable, long-lasting decking system.
ExoDek QuickClip is a glass-fiber reinforced nylon clip designed to absorb the natural expansion and contraction of real wood decking. When paired with Accoya, the system reduces checking and splitting by fastening into the joists—not through the deck boards—and creates consistent airflow under every board to prevent moisture buildup and mold.
The guide specifies exact groove dimensions required for compatibility: a 3/16″ groove height located precisely **0.40″ (±0.01″) from the bottom of the board**, with a groove depth of ½” (minimum 7/16″). Only one face of the board can be used for installation on 1×4 and 1×6 profiles because the groove is offset on thinner boards.
Installation begins with laying out the first row of board grooves, placing QuickClips at each joist, and fastening clips using #9 or #10 exterior-grade screws. Clip spacing diagrams show the correct placement for 5/4×4 and 5/4×6 grooved boards, including 1/8″ required spacing between boards. The clip’s “spring-back” flexibility allows the board to sit slightly above the joist surface, promoting airflow and eliminating joist shadowing.
Butt-joint details include recommended joist blocking, clip orientation, and expansion spacing. The flexible nylon material helps maintain even board spacing while accommodating movement across wider deck sections.
Removal instructions outline how to disengage clips without damaging the boards, and additional diagrams highlight starter-clip orientation, mid-board support, and transitions to breaker boards or picture-frame borders.
