I just poured a new driveway. Weather has been in the 60's daytime and mid-40's at night. Until the day of the pour. We had a sudden cold snap and the night time temp dipped to 28 degrees (the day of the pour). The temp was under 32 degrees for about 6-8 hours and then back in the 50's. The second day (which also was the 2nd half pour) dipped to 32 degrees for 5 hours and then back to 50's.
It's been 2 days and weather is now high of 66, low of 38.
I asked the concrete guy if I should hose down the driveway and he asked me if I have hard water. We do have hard water but not so bad that it spots windows dramatically. The concrete guy told me to wait a day and then I could hose off.
Just curious - why would he question the hard water? I will ask him when he stops by tomorrow but thought I would ask here.
