Project Overview

Once you’ve created your deck frame, its time to lay down your boards. Composite deck boards are a great alternative to timber decking because they require less maintenance. You don’t have to oil, stain or paint them because they’re engineered from durable materials that are built to last. Plus, they look and feel great. This step-by-step guide will show you how to lay down composite deck boards evenly and securely.

Step by Step Instructions

1 Attach your side board to the decking
2 Evenly space out your boards
3 Make sure your screws are in line
4 Trim the board ends
  • Step 1. Attach your side board to the decking

    After creating your decking framing (Refer to the video How to set out a deck), start by laying your outer board down. You’ll want some overhang on the edges of your decking. The thickness of a board is the ideal offcut length. So use an offcut to measure where your board should go. Then predrill your holes and use stainless steel screws to attach your first board.
  • Step 2. Evenly space out your boards

    When placing the rest of your boards down, make sure they have a consistent overhang (the width of an offcut) so that they’re all lined up straight. The minimum side-to-side gap between each board is 6mm. Just place your spacer in between the boards as you screw in and you’ll have an even straight line. 


  • Step 3. Make sure your screws are in line

    To make sure your screws are straight in line, lay all of your boards down and then use the straight line of an offcut to mark out where you want your screws to go. You’ll want a couple of screws at each joist under the decking. Put a few screws in along the length of the board to make sure you are happy with its position, before you go ahead and screw in the whole board. 
  • Step 4. Trim the board ends

    Use an offcut to mark up the overhang at the end of your deck. This should give you a nice even length that is the same at the other end. Use your circular saw to cut off the ends and you’ve finished your decking.

Health & Safety

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. 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. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
