Better put primer on it, if that's possible. Otherwise, you better fill it up.
Porous concrete does not do well with freeze-thaw cycles.
how to prepare a sandblasted concrete 33x14 in-ground swimming pool for freezing temp? I've decided to paint it next year. Do I cover it with tarp and leave it as it is? Thanks
