Does this grout need to be sealed? If so, how long after installation?

No it has a sealed in the mix, but sealing will better the bond , reseal one a year,where water is around a lot.

The sealer usually has in their instructions the time to wait for cure which my experience has been 72 hours minimum. Also, sealer is much easier to work with than grout. So if you can grout you will have no problem sealing it.
Was this Answer Helpful ?yes, it should be sealed after 72 hours. Time to cure grout came from sealer instructions.
