Step-by-Step Installation Guide
Step 1: Level the Ground or Build Your Frame
Start by creating a flat, stable base. For soil installations, compact gravel works best. Elevated decks require a sturdy joist frame.
Step 2: Fix the Joists
Install joists over your prepared base. Typical joist spacing depends on decking type:
| Decking Type | Joist Spacing |
|---|---|
| Square hollow | 300 mm |
| Circular hollow | 350 mm |
| Solid decking | 400 mm |
Pre-drill holes on joists for easier screw installation later.
Step 3: Install Decking Boards
- Attach starter clips at deck edges to hold boards in place.
- Use appropriate clips (plastic, U-clips, or square clips) between boards and joists. Gap sizes vary by clip type.
- Secure decking boards firmly using clips to avoid movement.
Step 4: Finishing Touches
Install WPC edging to cover gaps and give your deck a refined look.
