To install angled deck boards, particularly in a diagonal pattern, begin by positioning the central board and securing it using hidden fasteners according to specific placement rules.
Understanding Diagonal Decking Installation
Installing deck boards at an angle, typically 45 degrees to the joists, creates a visually appealing pattern but requires careful planning and execution. The key difference from perpendicular installation lies in how you start and fasten the boards, especially concerning joist crossings and board ends.
Starting the Installation
According to the installation guidelines:
- Place the central board first; ensuring to place the board at a 45° angle. This initial board acts as your baseline for the rest of the deck layout.
Fastening Angled Deck Boards
Proper fastening is crucial for the longevity and stability of your angled deck. The reference outlines specific rules for using hidden fasteners:
- Install 1 hidden fastener each time the board crosses a joist. This ensures each board is securely anchored to the underlying structure along its length.
- Always use hidden fasteners to secure board ends. This method provides a clean look without visible screw heads on the deck surface.
- Use 1 fastener per board end at butt joints.
- Never share a fastener across 2 board ends. Each board end requires its own dedicated fastener at a butt joint where two board ends meet over a joist.
By following these steps – starting with the central board at the correct angle and adhering to the specified hidden fastening techniques for joists and board ends – you can effectively install angled deck boards.
