How To Install Composite Decking

Installation Suggestions

Before starting construction think carefully of the location, design, and purpose of the deck you wish to build. By making a design and estimating the materials required, you can save time and money, and the job will go much faster. You should consult your local building code authorities before beginning. Basic construction skills are required. You may wish to consult a contractor. There are also reference books or websites for ideas. A well built deck will be a valuable asset to your home.

Tools Required

  • levels
  • hammer and drill
  • saws
  • measuring tapes
  • chalk line
  • galvanized or stainless steel nails or screws. Note: If you are using an ACQ treated sub-structure, this is very important because the chemicals can corrode other fasteners. Stainless steel fasteners should never be used where they may come in contact with galvanized fasteners or brackets.


1. The deck can be spanned to a maximum of 24” span; however, we recommend a 16” span on the center for perpendicular application of the boards. If a diagonal design is done, then a maximum of 12” should be used on center.

2. If you are using regular nails or screws, the deck boards can be used as you would with regular lumber. Be sure to put the fasteners through the thick parts of the board to get best holding power.

3. If you are going to use the hidden deck clip, the benefit will be a deck surface free of nail or screw heads.

    • You will need a chalk line as the clips should be attached to the joists in perfectly parallel lines. They should be laid out 5 ¾” to 5 7/8” (147mm-149mm) apart to give a 3/16” to 1/4” (5mm-6mm) gap between boards.
    • This will allow water and dirt to be cleaned out from

When building decking, it’s always  best to go into your garden and make several sketches of what the finished deck will look like and the area its going to cover.

You don’t have to be a talented artist, just a rough sketch put onto paper so that you have a clear picture in your mind about the square footage and, just as important, the surrounding landscaping.

Deciding what kind of bushes and trees, flower beds and rockeries, or areas of chippings or wood bark can all be done at the planning stage and put onto your sketch pad.
