Walkway edging and dry cement
I'm planning a walkway project and have already collected enough field stone to cover the area of the walk. I have two questions at this point:
1 - I recall seeing metal edging material that would be used to contain the sand that the stones would be set on. It was about 1/8 thick, 4" tall and came in lengths of 10' to 15'. I have not been able to find this metal edging at my local Lowes/HomeDepot stores even a local brick yard, no luck... Any ideas where I might be able to find that edging?
2 - Dry set cement.. I'd like to put down a layer of crush, then instead of just plain sand, a mix of 1 part portland cement to 2 parts sand. I'd like to put the sand/cement mix down dry and set the stones, then wet everything and let the cement cure. Anyone have any experience with that method? What's an appropriate mix ratio? What's the best way to buy the cement? Lowes has 94 lb bags for $9 each. Is that a good price?
