I made a small concrete patch along the edge of a room that I would like to set a PT 2×4 base plate on for framing. I prefer drilling and screwing with a lead anchor over using power actuated nails.
How soon after setting is concrete ready to be drilled? Is it enough to just dry it (like 24 hrs) or does it need more?

If you drill too soon after pouring I've found that it tends to flake and crumble around the drill bit giving you a much larger hole than desired.
After 24 hours, which makes it fairly hard, you should have no trouble at all.
