They are here fixing my driveway. I know they ain't coming back to after they leave today. I want to try and help the concrete cure right and not crack. I know you should mist it every so often. So assuming they pour the concrete about 3pm or so, do I need to mist it any today? i am assuming not.
Then starting tomorrow, how many times a day and how much should I wet it. Just a mist for 10 minutes or so, or do I want to flood it? If I remember right do it for about a week or so?
Temps here will be highs in the mid 90s lows in the 70s . i might also get some rain about 7pm, should i try and cover the concrete with plastic if it does?

They seem like they MIGHT know what they are doing. They did rub over the neighbor's mailbox. Makes me a little concerned.

Cover it to hold the moisture in that you spray.

I'd ask them before they leave. Seems like concrete takes 20 or 30 days to fully depending on weather. Spray it several times a day to prevent cracking during curing process. Maybe more if really hot. You don't want the moisture to leave too soon

Visqueen is what I see primarily for a cover but I've seen old timers use burlap bags. They said plastic would capture the moisture while burlap would allow for a more controlled moisture release. I really don't know which produced the best results.

Burlap or any cloth type material is better. If you can find a way to make a little dam around it I would flood it and keep it under water for a while.
Always remember concrete is only as good as the base you have under it. It will break up no matter how good the material and work is if you don’t have a solid base.

Maybe more if really hot. You don't want the moisture to leave too soon I understood 28 days as well. 24 to 48 for people to walk, 10 days for cars and light trucks. I can stay off it for a month if it helps. It'll probably crack.

It will crack. Guaranteed
Lines are cut or struck in the concrete to “direct” the cracks.
Outside concrete should never be “over finished”. Floated, at most a light troweling, then broom finished.
If it is over troweled it will peal.

I believe so, but we don’t use that term here. The top layer comes off. Usually takes a year or two. Looks terrible but the concrete strength is not much effected.
Had a 100’ x 30’ driveway do it. A couple older Irish guys helped. They were great finishers but they made it look too perfect, like glass! 18 months later the top layer started coming off. 😔
Worst thing was- it was my own house!🤣😂🙄😞

When I think of spalling it’s usually the rebar rusting and expanding causing the concrete to separate.

Just hose it down tomorrow afternoon. If it’s like today, maybe hit it twice. Give it a good squirting. I would not flood it, or cover it. It’ll be fine.
