How to lay artificial grass on decking
By Gavin Hall
Large area of decking makes the garden look bland
I remember watching those garden DIY programmes many years ago and there was always some decking added to the garden design. People now find that the decking layed all those years ago is starting to look grubby and uninviting.
As well as decking becoming grubby looking some people also have the problem of having too much decking in their back garden as you can see in this recent project we undertook (photo above). This simply makes your garden look too bland. A simple way to bring life back into your garden is to lay artificial grass on it.
The benefit of laying artificial grass directly on to decking is that it will save you money as you already have a flat, firm surface that should drain well if the steps below are followed. The more expensive alternative would be to rip out the decking, prepare the groundwork’s and then install the grass. Not something we believe is necessary as long as your decking is in good condition.
Here I will give you a tried and tested step-by-step guide on how to lay artificial grass on decking:
1. Prepare the decking
- Remove all garden furniture, plants, toys and anything else that has accumulated on it.
- Clean the decking with a scrubbing brush and water to remove any excess dirt, moss etc.
- If any decking is broken or rotten this will need to be replaced.
- If the decking hasn’t been treated recently we suggest you do this at this stage to maximize its life.
2. Install the underlay
Good underlay is a must to allow the grass to drain and to stop the decking showing through
If the boards of the decking have large grooves we will use an underlay for the artificial grass. This will prevent the boards of the decking showing through the grass in the future.
The 10mm underlay that we use comes in large rolls so we simply roll it out to the edge of the decking and cut. We then allow it to settle for a few hours. We use a nail gun to finally secure the underlay to the decking boards. This particular underlay has been designed with crosses in it to allow good drainage.

To work out how much artificial grass you need take a look at this guide on measuring your garden. Once we have decided how much grass we need we roll out the artificial grass and let it rest for a few hours to flatten out.
We fit the artificial grass in the same way as we do on any other surface. See our guide on how to fit artificial grass.
In this example we fitted the Grange grass but any of the grasses from our product range would be suitable to lay on decking but do make your final selection based on how it will be used. If you expect large footfall we recommend a grass with a short pile like the Outfield.
A design tip: In our example above we wanted to give the garden some definition and to create some different areas so we left the bottom area as real grass and the top area as decking.
