Overview

Composite deck boards are a great alternative to timber decking because they look and feel great, and they require less maintenance. You don't have to oil, stain or paint them. This step-by-step guide will show you how to lay down composite deck boards evenly and securely using Ekodeck’s Quickfix concealed fastening system.

Steps

1Attach your edge board to the decking

After creating your deck frame, start by laying down your outer edge board. (This process will differ slightly depending on the style of Ekodeck board you have selected.) If using Ekodeck+ Designer Series, we have edge boards available. The Designer Series edge boards have a distinctive groove underneath the board. This groove is where you install the C-Clips, before pushing your edge board into position

2The Quickfix clips

The 6mm Quickfix kits come with all the clips and screws you need to install your decking. The three clips in your Quickfix kit are:

Standard clips

Standard clips space your boards apart automatically, setting a consistent gap while anchoring your boards to the subframe. They are designed to hold the boards down while allowing them to slide along the clip as they expand and contract.

Locking clips

 Don’t forget to install the locking clips! Locking clips pin your boards in place, preventing them from shifting or popping out of alignment as the boards expand and contract. We recommend placing one locking clip in the centre of each board.

C-Clips

 C-Clips have a variety of uses. They can be used to start your deck from a wall and installing our Designer Series edge boards. Because the clips are hidden, they are also handy when it comes to stairs and fascia boards.

3Fastening your decking

After you’ve installed your first board or edge board, you can begin installing the rest of your deck using Quickfix clips. Start by placing a locking clip in the groove of the board, nearest to the centre. Screw down slightly to hold the clip in place. Next, insert standard clips in the groove of the board on every remaining joist, screwing down slightly to hold the clips in place. Push your next board into position, and continue to install clips as outlined above. Once you have installed six to 10 boards, ensure your deck is square by measuring out from your first board at both ends. Continue screwing down all screws until they seat firmly in the clips. (You don’t need to over-tighten screws in standard clips; locking clips need to be sufficiently tightened, but screws in standard clips just need to seat firmly in the clip.)

4Trim to length

Repeat this process until you reach the end of your deck.

If you’ve started from the outside edge of your deck, the last board should finish up against your house. Often you will need to rip this board down to be the correct size, which can be easily done using a circular saw. In order to fix the last side of the last board on your deck, predrill an oversize clearance hole, countersinking and fastening using a 10g stainless steel screw at every joist. (Clips won’t fit or there won’t be a groove in the board.)

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
