In this question, the user asked about curing sodium silicate with calcium chloride. My question is, will the resultant product be insoluble in water? I know calcium silicate is only very slightly soluble, but I'm expecting it's going to be a bit more complicated than that.
I'm not a chemist, and wanted to know the answer to something I'm messing with at work to know if I need to hire a materials professional.

    $\begingroup$ No, it is really as simple as that. You'll get calcium silicate, which is insoluble. $\endgroup$ – Ivan Neretin Oct 9 '19 at 12:51
  • $\begingroup$ Where does the sodium go, in this case? Is it displaced into the water to become sodium chloride? And would the calcium propagate through a "thick" structure, or would this only be a surface coating? $\endgroup$ – Joe Oct 9 '19 at 12:55
  • $\begingroup$ Yes, Na remains as NaCl. And yes, propagation may be an issue. $\endgroup$ – Ivan Neretin Oct 9 '19 at 12:59
  • $\begingroup$ That's alright, I only need a surface coating. If water can get to it, CaCl2 can get to it during the wash and then it's 'sealed'. $\endgroup$ – Joe Oct 9 '19 at 13:08
  • $\begingroup$ It really doesn't matter whether this is actual homework or not. I have decided to reopen the question, because I don't think it should have been closed as homework in the first place. $\endgroup$ – Martin - マーチン Oct 10 '19 at 12:54
