How to Lay Synthetic Grass


How to Lay Synthetic Grass

There are basically 6 Steps to laying synthetic grass.

Step 1. Measure + Prepare Garden or Lawn

To get the best from your new artificial lawn, make sure the area drains suitably, or puddles will form when it rains, along with mould and mildew, which could ruin your grass.

To buy the correct amount of synthetic grass for your new garden, measure the size of the garden or lawn area. For an accurate measurement, it is vital that the ground is smooth and flat. That means removing any natural grass, shrubs, steps or anything else you don’t want in your new artificial lawn.

But before you begin, get someone to help you; laying synthetic grass is a two person job and make sure you have these 6 items to get the job done:

  1. tape measure
  2. utility knife
  3. tough leather gloves for protection
  4. hammer
  5. spirit level
  6. broom
  7. turf cutter
  8. skip for grass and garden debris
  9. bob cat or truck (you can hire these here)

Remove your lawn using a turf cutter. Excavate the ground down to a depth of 75mm (3 inches). Add weed killer to the area to kill off weeds.

 You will also need:

  1. synthetic turf (Call Hugh for a quote)
  2. joining tape
  3. brickies sand
  4. turf pegs


If your lawn does not have an edge or wall, you need to create a boundary. This not only defines the lawn area but also helps to protect your synthetic grass from being torn.

Flatten the ground to remove bumps or left over debris. Level the area you wish to cover. Use a heavy duty weed barrier as a lining for the sub-base; then add stone, sharp sand and granite dust. This prevent weeds coming through your synthetic grass. Do not over fill with sand; it can causes dips and other irregularities when you lay grass.

Step 2. Roll Out Synthetic Turf

How to lay synthetic grass? Roll out your artificial grass. Make sure you use good quality Australian synthetic grass or your results won’t be as good as you expect.
Stretch out the grass over the area and leave it flat and unrolled for at least a day and night. This allows creases to come out and the turf pile to settle. Creases will fall out. Your grass is not faulty; so don’t panic.

Always check the pile direction of your fake turf. Test laying your turf in the opposite direction. This helps to check the shade from one angle to the next.
Always check this before cutting! You may prefer how you lawn looks when it is turned around.
Once the artificial grass has settled, carefully cut the boundary with a sharp trimming knife.

Step 3. Pegging Synthetic Turf

Once you have laid out your turf and satisfied with the direction of the pile, you can peg your turf. Start pegging at the edge of the turf. Hammer pegs into the ground, spacing them evenly along the edge; between 200-300mm apart.

Where a boundary has been created using wooded battens, use galvanised scews or grip nails to secure the edge of the grass to the top edge of the battens.
You won’t see the nail heads through the pile.

Step 4. Roll Out Second Turf Length

Once you have pegged the first length of turf, roll out the second length, cutting it with a utility knife.

It is best to cut this longer; trimming it later.

Step 5. Adhesive Tape to Join Synthetic Lawn

You want your lawn to look like one natural piece. The best way is to join rolls of synthetic grass together with adhesive joining tape by rolling out the tape the length of the turf and cutting it to size. Fold back both edges of turf where you want them to join.

Remove backing paper from the adhesive tape. Place half of the tape under the edge of the first length of turf you laid, pressing it down, so it sticks to the tape. Do this along the full length of the turf.

Placing the second length of turf next to the first, and making sure the blades of grass are running in the same direction, move down the turf, sticking the adhesive tape to the grass as you go. You should get a seamless field of green.

Trim the grass at the ends so it fits the area and hammer pegs into place to secure the grass around the edges.

Step 6. Brush Pile & Sand

Once you have rolled out and pegged all your artificial grass, its time to brush the pile using a stiff outdoor broom.

Add silica sand as a top layer to the your grass. It keeps the grass in place, and makes the grass feel more natural under foot.

This is how you lay synthetic lawn. It is not always easy.
