I recently built a shower using this same type of grout, but a different color. The matching silicone caulk I used was suitable for wet locations (picture below). I used this caulk in the gap between the vertical shower corners but I used up the one tube I ordered from HD and used clear silicone caulk along the horizontal shower to base gaps, and the ...
I am assuming that you have cleaned off the surface thoroughly. I would probably try to sand the area where you want the caulk. I would only imagine that if there is any soap residue that the caulk would just slip away. Curious if you tried that, I'm sure you have, if not I hope this helps.
All Portland cement based grout benefit from a sealer. I prefer the distillate based sealers, but I hear good things regarding the newer water based sealers. One grout type doesn't need any sealer: 2 part epoxy grout. A bit more care and effort during install, but nearly bullet proof afterwards. Shower floors and foyers really stay clean.
I have done this many times in the past. Make a weak solution of bleach and warm water (this works best) or if you don't want to use anything as aggressive then make a paste out of Bi Carbonate of Soda and Vinegar. Apply either solution to the affected areas and leave to soak for half an hour. Take an old toothbrush and scrub until the mould has gone. ...
If your thinset is a couple days old or less then slight wet the thinset sticking out and go at it with a flat head screwdriver. Usually scrapes out pretty easy the first few days.
You need to remove the thinset by grinding it out, otherwise you'll end up with uneven coloring in your grout. Thinset is also stiffer than grout, and the added rigidity could cause your tiles to crack in the future. You'd be best off biting the bullet and grinding it out now rather than replacing the tile entirely later!
You make a good case for an early warning system saving major money if it does leak. If you are truly 90% supported, silicone sealing won't add any support. The pan-to-drain seal and your drain pipe connections are more important.
It probably doesn't matter much one way or the other since it's unlikely for water to get that far. I personally would not bother. Consider this: If water were to get that far, you would want to know about this and take action. If it's sealed, water could just sit there unnoticed, rotting out anything it touches. If it leaked down and stained the ceiling, ...
As best as I can tell, the brand for that is Sol an Italian manufacturer. The logo looks identical.
