Water Concrete Slab After Pouring?
Posted on 2/1/18 at 12:16 am

Should I water my concrete slab after they pour it? If so, how often should I water it?
I live just outside of Baton Rouge.

Keep wet for a couple of days if possible.

Concrete that is moist cured can be stronger and have less surface cracks. It wouldn't hurt to keep it wet for about a week.

Definitely, baw. It won’t bloom without some H2O. Save the bees.

Concrete will increase in hardness by water curing for up to 30 days. However, the biggest increases are in the first week. So either build berms and flood it or run a sprinkler. Most don't bother going longer than 7 days and if you are in a hurry you get about 75% of a 7 day cure in just 3 days. The full 7 day moist cure will increase the hardness by about 50%, well worth the effort and cost of the water.

How long until I can walk on it and start watering?

Temp dependent but you should be okay to walk on it in 6-8 hours in tennis shoes with no issues whatsoever. No hard soles with heel.
You can do more damage with a hard stream of water. Use a little caution when putting the water to it.

Absolutely. Concrete cures for decades after it’s been poured, constantly using moisture from the ground further the chemical reaction. This is why “green” concrete under older homes is hard as diamonds...many years of curing using ground moisture. The chemical reaction that takes place during curing releases heat, evaporating a good bit of the water away. Visqueen during the initial phase prevents the evaporated water from leaving the slab. There are probably some good guidelines on the web

Also, I could be wrong but I think putting water on immediately after pouring can thin the top-most layer (“cream” I think they call it) and cause lots of surface cracking

Not an expert, but doeant this depend on the concrete mix?

Cover with cotton batt curing mats and water em down once a day. The longer you leave them on the better your top surface will be.

You could alternatively spray on a curing compound. I wouldn't recommend it if is an interior slab that it is receiving floor finishes, as there could be compatibility issues.
If you water cure, keep it wet for 7 days as others have suggested.

I wouldn’t worry about it unless it’s very hot. This time of year, it would not be worth your time and could cause more harm if you set up sprinklers too early or if you have some bird baths in the slab
