Well I was only using the sand once, and with a 3/8 dia nozzel on a pressure feed tank it stripes an 1 1/2 path at one time but my backyard looked like a beach. the cost of sand i was paying about $8 to $12cdn for 100 lbs. For an air compressor i have a diesel that is ment to run a couple of jack hammers and a sand blast tank holds 150lbs of sand. Might check with Princess Auto for tools as well.
