More often than not, wrinkles or creases tend to appear in your artificial grass, especially during the hot summer months. These wrinkles could be as a result of poor-quality turfs, poor installation techniques, or high temperatures. However, we have a bunch of techniques and methods you can use when installing your artificial grass to prevent them from getting creases in future.
But first, let’s understand further what causes this problem.
Causes of creases on artificial grass.
The most common cause of wrinkles on artificial grass is poor installation. One good and bad characteristic of artificial grass is that it has the ability to mold itself to any shape offered. This means that if you put a piece of artificial turf over a brick or piece of wood and leave it out in the hot sun for a couple of hours then remove the brick or wood, the piece of artificial grass will hold its shape and the crease will most likely be very difficult to eliminate. This occurs due to the heat from the sun that warms up the backing of the artificial turf, making it more flexible; and when it cools off, it memorizes its shape.
In other cases, your artificial grass could be installed carefully but still develops creases later in the days. As mentioned earlier, the sun’s warmth plays a significant role in triggering the backing material of the artificial grass, making it more flexible. The heating from the sun followed by the cooling off of the backing material later in the day can trigger the development of creases on your artificial turfs. It’s important to note that this will occur regardless of your turf’s quality.
However, these wrinkles and creases can easily be avoided by adhering to a couple of standard installation techniques.
Installation techniques to prevent wrinkles on artificial grass.
1. Lay flat the weed membrane.
In most circumstances, unless you have a pet, it’s highly recommended to install a weed membrane directly under your artificial turf to block weed growth. Also, when you unfold your artificial grass, ensure that its membrane hasn’t folded over itself. You can achieve this by attaching the membrane to a wooden edge material with galvanized nails and fixing it in place in at the middle of your lawn using U-pins. If there will be any folds or wrinkles, they will be visible through the artificial turf since its backing material takes the shape of any lumps and bumps in the membrane.
2. Allow your artificial grass to adapt before cutting.
In a good case, you should install your artificial turfs on a hot and sunny summer day. This will help the backing material become more supple and easier to install. Once all ground preparations are done, you should then unroll your artificial turfs and lay them flat across your lawn or backyard. After this, you should give them some time to adapt to that hot environment. It’s recommended that you leave the fake grass across your lawn for a minimum of 2 hours and for the best results, leave it for 24 hours. This will allow it to familiarize with the hot environment so that when installation time comes, your turfs will already be stretched enough.
3. Stretch the turfs tight and push out any wrinkles.
Using a carpet kicker, stretch out your artificial turfs while kicking out any creases formed after leaving the turfs to adapt. Alternatively, you can use the cardboard core where your artificial grass was wrapped around to push out any air bubbles. If you find any stubborn creases, you can install your turfs using U-pins by sticking them directly into the turf to pin it in position.
4. Use the right amount of sand infill.
Using the right amount of sand infill in your artificial grass plays a significant role in preventing wrinkles on your artificial turfs. The sand infill will add ballast to your artificial grass which will pin the grass to the base material, preventing rippling. Moreover, sand infill helps control the temperature of your artificial grass, preventing creases caused by the heat form the sun.
Conclusively, it is best that you leave the work of installing artificial turfs to professionals. This is because as much as you can DIY, there are certain small important things that the experts have learnt through experience. However, preventing creases on your artificial turfs shouldn’t be any more challenging when you use the guidelines discussed above.
