It will depend on where you will need the glue for your installation: if you are planing to glue the entire artificial grass piece of 15’x15’ on a solid surface, a 29 oz turf glue won’t be enough, you will need to get a gallon which is the next available pack size. If you are using the turf glue just for the seams, a tube of 29 oz turf glue will cover a seam length between 9’ and 12’.
