What adhesive should I use to bond artificial grass to concrete?

If you’re trying to bond artificial grass to concrete and are unsure which artificial grass glue you should use, then look no further. Here’s two different adhesives you can use for bonding artificial turf to concrete. We’ll also cover some of the things to consider when choosing one that’s right for you. 

What to consider when bonding artificial grass to concrete?

1. Firstly, your adhesive needs a high level of initial tack to ensure that it can grab on to the surface of the concrete as well as the grass. If your adhesive isn't suitable, you might find that the adhesive will cure without bonding to the concrete at all.
2. Secondly, it's very important that your adhesive has a high level of finishing strength and is able to endure the different elemental conditions once cured. Temperature, wind, moisture and many other natural weather factors can play a huge role in the long-term performance of your adhesive. Make sure your adhesive is suitable for these conditions and check with the manufacturer. Any reputable adhesive manufacturer or reseller should be able to provide you with a product data sheet for your adhesive.
3. Thirdly, it is important that your adhesive has a very high level of flexibility. This might sound strange, but it's a very important one. Here's why. When all materials (including artificial grass and concrete) are heated and cooled down, they will expand and contract to different sizes. This may be invisible to the naked eye often, but look deeper through a microscope and you'll see some big changes. So why is this important? As the weather gets warmer or colder during the summer and winter months, your artificial grass and concrete will expand and contract. The problem is that the concrete will expand at a much smaller rate that the turf, meaning that the artificial grass is essentially being pulled away from the concrete.If your adhesive is to rigid (like many products on the market), the adhesive will not be able to expand alongside the grass whilst maintaining its bond to the concrete and a failure will occur.
