Joining composite decking boards, especially when creating a butt joint where two board ends meet over a support joist, is typically done using specialized decking clips. This method ensures a secure connection while allowing for the material's expansion and contraction.
Creating Butt Joints with Decking Clips
When composite decking boards need to meet end-to-end, the joint should always be positioned directly above a support joist. The provided reference illustrates a common technique for joining boards at a butt joint using decking clips.
Here's a breakdown of the process:
- Position the Joint: Ensure that the ends of the two composite boards you are joining meet precisely over the center of a deck joist.
- Place the Clips: Where your boards meet, you will be using two decking clips on each side of the joint. These clips sit directly above the joist, one for each board end.
- Secure the First Board: Screw down the two clips designated for the first board end. These clips hold the end of the first board securely to the joist.
- Secure the Second Board: Once the first board's clips are fastened, place the remaining two clips for the second board end and screw them down. This secures the end of the second board to the joist, completing the joint.
This method provides a strong, concealed fastening point at the butt joint, crucial for maintaining the integrity and appearance of your composite deck surface.
