    Okay to pour concrete in rain?

    Maybe this is a rookie question but my PB wants to pour our pool Monday and it is supposed to rain. Should I have him wait until a clear day?

    PB says if it rains they won't pour - I misunderstood him. However, that presents new question. If pool is poured and it rains same day of pour, is that bad for the stability of the concrete?

    If it rains the day they pour it, they usually tarp it. After a day, it usually won't hurt it to get rained on.

    A bit of rain typically only affects the cosmetic appearance and has little to do with it's stability.

    In general concrete (not sure about pool specific stuff) should be kept wet for several days after it is poured or should be painted with sealer to lock in moisture so it can cure correctly within 24 hours of being poured. This can be done a number of ways, through the use of wet burlap, running lawn type water sprinklers on timers every X hours, covering in plastic, etc. Failure to seal or keep freshly poured concrete wet for the first week or so after it is poured tends to lead to surface cracking.
