How much and how often do I need to sprinkle with water newly poured
concrete patio and footings? I am in NJ and temperature is over 90
degrees, humidity is almost 100%. Anything else I need to do to ensure
proper curing of concrete?
For the footings, I'd just cover them with plastic for at least 24
hours-- If you can wait a few days before uncovering, all the better.
I used a sealer on a slab in my basement and was pleased with the
results. It gets sprayed on liberally as soon as the concrete stops
puddle-ing. It slows evaporation so you don't get surface cracks. It
was about 1 year ago & the slab still looks wet. That may or may
not be what you want for your patio, but it is worth looking into.
Just remember that concrete doesn't reach full [95% anyway] hardness
for a month. Take it easy on it especially around the edges.
[and air-entraining that patio is a good idea]
You could have been less-stupid and put off pouring it until the
temperature was more optimal for producing a high-quality, high-strength
You're going to have a lot of water loss through the bottom surfaces
into the ground - which you can't keep wet from the top side.
Yeah, right. Like the world stops when it gets hot. Concrete has
been placed for centuries in hot weather. The problems are not
insurmountable, and waiting is not really an intelligent option.
Wet it down and cover it with plastic. Wet it until it the concrete
turns dark, and maybe a little more. How often you have to wet it
down will depend on many factors, but the answer is the same - keep it
wet and dark. Don't drown it.
I did my driveway by hand in sections 10x8...after pouring cement and
finishing I then layed blankets on the cement, covered with plastic and kept
wet for 2 weeks.
That was 30 years ago and no problems. I had 18 inches of bottom ash from a
local power plant as a base also..along with reinforcement wire should last

You did not ask if it would be a better idea to wait unti the ambient
