Decking demands care and maintenance to keep off the moss. Besides, it may rot or look weathered with time. You can install artificial grass to replace old and slippery decking and get rid of the grubby surface on your outdoor space.

Furthermore, the installation helps avoid expenses incurred in repainting the decking whenever paint peels off.

Although it may seem like a daunting task, covering your decking with artificial grass is easy! Nevertheless, you will need to follow precise guidelines for the best results. Luckily, you are ready to transform your garden by laying fake turf like a pro with this article.

Are you wondering how you should lay artificial grass on decking? Read on!

1.  Measure the Decking

You’ll have to measure your decking before ordering the turf. You don’t want to order more grass than your decking needs, and besides, some companies don’t accept returns on cases where you buy excess artificial grass.

Calculate your decking area to determine the number of artificial grass rolls you need to cover the surface.

2.  Preparing the Decking

Grubby decking may have plants growing on it; you’ll have to uproot them, remove garden chairs, tables, and any other outdoor installations on the decking.

Use a brush and clean water to scrub off any moss and accumulated dirt. Finish off by hosing the decking using high pressure to remove any extra dirt or moss.

Check for rotten and broken decking and replace it before laying the artificial grass. You can buy replacement planks from a garden store at a low price, but you will have to ensure that they are level with your decking.

Replacing the rotten or broken planks is an easy task that you can DIY. You can use replacement boards even if they don’t precisely match your decking. After all, laying artificial grass will completely mask the decking.

Treat the decking more so if you haven’t done it in a long time. Treatment prolongs the lifespan of any decking.

Check on the condition of the weed membrane attached under the decking. The membrane prevents weed growth on your decking. If the membrane needs replacement, install a new one before fitting artificial grass onto decking.

3.  Installing the Underlay

Make sure you allow the decking to dry before installing the underlay.

An artificial grass underlay helps drainage and prevents the decking or boards from showing through the turf. If your decking’s surface has grooves, you’ll need to install the underlay before laying the artificial grass.

Depending on the surface of your decking, you can opt for the underlay or install the grass directly. If your decking surface is even, the underlay is not necessary. Nonetheless, installing the underlay before fitting artificial grass onto decking is excellent in preventing the boards from rotting, which results from poor drainage and excess puddling on your turf.

There is different sized synthetic turf underlay, but the most common ones have a thickness of 10mm to 20mm.

A. Marine Plywood

Marine ply is ideal for decking with large grooves; it creates a flat and robust area for fitting artificial grass onto decking.

This underlay is solid with no drainage modification structures, so you will have to drill holes on its surface before fixing the artificial turf. If the underlay does not allow for proper drainage, you will observe puddles on the grass, especially after rains.

Ensure that you get rid of all the dust before laying artificial grass on the plywood – you can use a vacuum cleaner for this purpose.

The underlay is firmly secured to the edges of the decking using nails. You can opt to buy a nail gun for this.

B. Foam Shock Underlay

Before ordering, you’ll have to measure your decking to ensure that you order the underlay’s ideal length.

There are a variety of underlay sizes that you can choose from according to your preference. For instance, you can opt for the 20mm one, sold in rolls of 5 meters to 20 meters long.

You’ll have to stretch the underlay to the decking edges and trim it out to fit perfectly. It’s then left for about 4 hours to settle. Remember to secure the underlay to the edges firmly.

The foam shock underlay absorbs weight on the artificial turf. If you have children, this type of underlay is your best fit – no more severe injuries to children playing on the turf. Besides, it has a proper drainage structure that ensures there are no puddles when you walk on the grass.

Nevertheless, this type of underlay is not ideal for homeowners with pets, especially dogs. The dog’s urine can potentially cause an odor.

4.  Choose the Artificial Grass

Different grace ranges come with varying pile and density.

If you opt to install the artificial grass directly without underlay, ensure that you choose a grass range that has a thick density. Furthermore, a short pile is ideal if you intend to play football on the grass.

5.  Laying Artificial Grass on Decking

After a few hours, when the underlay has settled, lay the artificial grass on it. Unroll the grass from one edge of the deck to the other.

You’ll have to cut the grass whenever its length exceeds the decking surface. You can later glue the joints together. Moreover, if you order less turf than you require for your decking surface, you’ll need to join grass rolls using glue and a synthetic grass joining tape.

Make sure you avoid touching the grass blades with the tape or glue when joining your turf. Brush through the grass to mask any visible lines.

When the decking is entirely covered, flatten the grass and give it time for the wrinkles to fade out, then tack the grass around the edges of your decking and secure it using nails.

Are you thinking of using glue instead of nails? Artificial grass is just another installation that you can replace or remove at any time. If you glue the grass to your decking, you’ll have to tear the grass or peel off the decking when removing the grass.

It is better to use nails instead of glue.

Nevertheless, an adhesive is used for an extensive decking surface to ensure that the grass holds on the underlay; otherwise, nailing the edges will do for a small one.

Order slightly more grass than you measure to allow for smooth folding and nailing at the decking edges.

6.  Brush through the artificial grass

After laying the artificial grass, use a brush or a rake to sweep through the grass.

You can groom the artificial turf by placing flower pots or other decorative structures at the corners. Besides, they reinforce nailing and hold the grass in place at all times.


Many advantages come with laying artificial grass on decking; the grass is easy to maintain, comfortable, and safer than the slippery decking.

Fitting artificial grass onto decking is a simple activity, especially with the extensive guide in this article. You’ll have to prepare the decking, install the underlay (optional), and lay the synthetic turf making sure you secure it firmly on the edges.
