Should I be concerned?

Cool, thanks.

I'm surprised they plastered with temps going down that low. When my pool was built, I had to wait until April for plaster because it was already October by the time they were ready for it. They told me they wanted temps above 50 deg F in order to plaster.

It was probably around 65 degrees when they started, 52 degrees when they finished, but that night/early morning it dipped to 36.
