I have lived through many tile jobs and have never sealed them. There is no trick to it. Rinse, squeegee the wall and floor then Dry with the towel you just used to dry yourself. The floors looked great because everyone were taught to be respectful and careful of their environment and clean up anything they spilled immediately. Didn’t have any pets and all their problems so rugs looked great too.
Having a water softener eliminated the lime and ferrous iron issues. But that’s just us.
