Steps To Perform Before Laying Artificial Grass

Steps To Perform Before Laying Artificial Grass

Here are some steps that you need to follow when you are thinking of installing artificial turf on the decking.

Check the quality of Decking

First, check the quality of the decking to know whether it is suitable for the installation of artificial grass. In general, most wooden or composite deckings can be easily considered for artificial grass installation. However, prior to the installation, you need to check the gaps between the decking boards. They should ideally be 1 cm or less.

If you have wider gaps, then it may be possible that fake grass will sag into the larger spaces in between, eventually ruining the entire project. So, there is a need to fill all the gaps as much as required and have the decking boards in a perfectly seamless condition.

Clear The Area

Now, clear the area around the deck. Remove all the furniture, plants, and other stuff from the deck to make it completely clear for the installation of artificial grass.

Clean The Decking

Now, after the removal of furniture from the deck, it’s time to clean the deck completely. Scrub the surface of the deck completely. If the protective coating or sealant has been removed from anywhere, reapply it to make the deck surface secure.

For a more effective and hygienic cleanup, it’s even better to address the entire deck with an anti-bacterial commercial cleaner, so as to get rid of any bacterial or mold buildups. Doing so is super crucial since the microbial buildup is likely to take place again under the fake grass. You can also make use of homemade cleaners that are meant for stain cutting, and eradicating contamination or odours.

Apply A Damp-proofing Treatment

Now apply a damp proofing treatment to the floor of the deck. This step is optional; it depends upon you whether you want to apply it. But you must know that the damp proofing system will protect the deck from water by keeping any possible moisture damage at bay.

Allow To Dry For 48 Hours

If you have applied the damp proofing treatment to the deck floor, wait for 48 hours to let it dry. Once the proofing system has dried, you can start the installation of the astroturf.

Now it’s time to add underlay to the floor of the deck. Underlay is very necessary because it will cushion the grass floor and prevent it from sinking into any depressions present in the deck floor.

There are many types of underlay available on the market, but the most common underlays that you can use for the installation of artificial grass on decking are Foam Shock Underlay and Marine Plywood Underlay. Foam shock underlay comes in big rolls; so you need to spread the roll from one corner of the deck to the other corner, followed by cutting out all the additional parts.

Foam-shocked underlay can easily bear the weight of heavy furniture and also protect children when they fall on the floor during games.

The alternative to foam-shocked underlay is marine plywood underlay. It is not as good as a foam underlay, but it is still beneficial. When you place plywood underlay directly on the deck, it will create a completely levelled surface for the grass installation.

3. Lay The Grass Onto The Level Area

Spread the grass completely on the floor in such a way that it will cover every corner of the deck. There are two methods for fixing the astroturf.

Glue and Tape Method

For this method, we have to use adhesive glue that is specifically made for the installation of artificial grass. After laying the grass roll on the deck, fold the first corner of the roll and apply a generous amount of glue to it, and in the middle of this corner, apply the tape to fix it.

Now cover the second corner in the same way. Fold the other two corners of the grass that are still untreated to the middle of the grass carpets. Apply glue and tape to the middle of the grass and then re-spread the grass rolls. Do it carefully to avoid any bumps or unevenness. Now glue down the remaining two corners and the installation is completed.

Moreover, you can consider this method for the flawless installation of artificial grass on balconies.

Nail Down Method

The other method for the installation of fake grass on the deck is the nail-down method. This method is comparatively easier than the glue-down method because it takes less time. Fix the nails on the edges at a distance of 40 mm x 2.5 mm. It will secure the artificial grass carpet on the floor of the deck.

Important Note: The nail-down method is much more beneficial as compared to the glue-down method. If you have to remove the grass from the deck floor for any reason, Nails can easily be removed and separated from the grass floor and the deck floor. But if you fix the grass floor with glue, then removing it from the deck will tear the grass carpet.
