I believe I.D. 2 is what we call top coat or sometimes 9 MM, I say believe because I don't recall anyone calling it I.D 2. If that is the case I would not use it as only shot. It is made up of smaller stone which gives it that smoother look.
Yes, you are correct, the ID2 is what they are using as a top coat around here..Thats our "smooth finish" mixture that gets used on all of the 2 layer driveways...
The one company wants to use ID3 which i believe is 3/4" stone and 1/2" stone?? From what I read, wouldnt this absorb more water than the ID2?
What are your thoughts on millings??
