Do wires need to be flat. I was running 12/2 along my joists...and when I pull the wire from the coil, it has a natural twist to it. My perfectionist side says to untwist them so the romex lays flat along the joist along its entire run, but this has been frustrating at best.
I know the concrete is supposed to reach it's rating in 28 days ie - 3000psi concrete takes 28 days to reach that rating, but to wait that long to drive on it seems rediculous.He has a Mustang in storage that weighs 3200lbs and I figured he'd be fine driving it across the driveway into the garage after a week of cure.e: When to drive on new concrete driveway? My guy asked for seven days for driving cars and not to actually park on it until 14. 28 days is to keep heavy contractor trucks from using it.
Try again after a 2 to 3 hours have passed if the driveway is still tacky initially. Some sealcoats take 12 hours or more to dry enough to allow foot traffic. Allow the sealcoat to dry at least 24 hours before driving or parking a vehicle on it. Application of sealcoat in hot and dry weather will speed drying time over periods when it has been applied in damp and cool weather. 2  In all cases, rather than testing the sealcoat for early access to foot traffic, you can just wait the 24 to 48 hours and open the driveway to all traffic.
