I have a repeat customer ask me to do 3200 sf of artificial turf. I've gotten some different responses saying put it on RCA, sand, stone dust etc. I need to contact the manufacturer but I would rather hear from someone who's done it. He wants to buy the turf(it's around $2/sf) he wants me to prep and install. What do you do around mulch beds? How do you seam it together? Do I need to remove all the old grass? Anything else you can throw my way would be appreciated.
