Fitting Fake Grass to Decking

Is your decking starting to look a little tired? Has it become a hoarder of green moss? Or perhaps your mobility means you’re cautious of slipping? Whatever the reason, if you fancy a change and are considering fitting fake grass to your decking then this handy guide will help you through the process.

Step 1. Prepare your Decking

Remove all surface objects such as garden furniture, plant pots and any other bits and bobs that take habitat on your decking over the years. Clean the decking with a stiff poly brush and water to remove any excess dirt or moss. Allow the decking to fully dry out before proceeding to step 2.

Please note: If your planks are due a protective coating or there are any rotten or broken planks, then these will need treating before continuing. Replacement planks are often quite cheap from your local DIY store. Don’t worry if they aren’t an exact match, as long as the height is level – they will not be visible when the install is complete.

Step 2. Optional Underlay

When it comes to underlay, it is important you select the right one. Underlay without ample drainage can act as a sponge for water which not only prolongs the drying process but after a heavy downfall can cause standing water. You need to make sure the underlay is capable of moisture release to filter away the water.

Depending on which artificial grass range you go for, the density of the grass can provide enough cushioning to fulfil the purpose of underlay. Sceptics will argue that without underlay the grooves in your decking could portray through the grass over time, however, a good quality artificial grass will prevent this. For further reassurance, you could infill the decking planks with sand to eliminate the grooves completely.


Step 3. Choosing your Artificial Grass 

When selecting your grass, we recommend looking for a thicker density and pile height of at least 20mm. Our Bordeaux or California ranges are particularly popular for decking coverings and come with impressive 4 year extended warranties.
