Thanks for your reply! Yes I plan on asking him about jobs that used this mix when I talk to him later this week. He is a super nice guy and has been very helpful and gone out of his way to help us with some “extras” The job is about a 7,000 – 8,000 sq. ft. job so I want to make sure I’m happy with the final result! I just want to gain a little knowledge before I talk to him. I really don’t know anything about the process. From my reading this morning I see the suggested depth is 4″ Our bid is for 2 1/2″ which has me a little concerned. Should we up the depth? I see parking lots in our area have “smooth” surfaces so maybe that is a possibility?
