was easier than I thought it would be... hopefully it doesn't crumble when we pick it up.. but I watched enough concrete being laid.. used my hand like a float after it was down.. I can see where it can be easy to get the wrong mix by adding too much water.. or not enough.. good news is with all this humidity the plastic bag looked like it was raining on the inside.. should be and moist under there.. get a better cure I think
