I am replacing the posts that hold up my patio roof. I've poured new concrete pads, and need to drill holes for the lead anchors that will hold my post brackets in place.
Must I let the concrete cure before drilling the holes for the anchors, or is it easier to drill before curing?
My anchors are 1/2" diameter. Do I need to predrill a smaller hole to keep it from "wandering" or is it safe to drill a 1/2" hole right off?
