Can you lay artificial grass on hard surfaces?

I want to know if it is okay to install artificial grass on hard surfaces.

Yes, you definitely can lay artificial grass over hard surfaces. If you are installing artificial grass over concrete or hardwood surface and the installation is permanent, you will need turf glues to glue the turf on it. By doing so, you will also need some simple tools such as a carpet knee stretcher, carpet knife, tape measures and 1/4” towel. Most of turf glues will need a bit time to set, so for such installations, experiences and patiences are preferred. Depends on the size of your installation, you might want to find a professional to help you with the installation. You can purchase all the artificial grass along with turf glues from us on our website.

My father used turf glue when he installed the artificial grass on our patio.

Yes. Needs patience in this though! I might contact a professional in doing this work.
