I had already heard about the additive for grout. I'm pretty much at the mercy of Home Depot, Lowes and some other local chains. I get the same response from all when I ask about a latex additive for grout and that is they don't know about or have it. They have it for mortar & adhesive but not grout. So if you have some specifics on the brands there please tell me.
I'm looking at these options right now:
1) Laticrete Spectra Lock Epoxy - Doesn't need sealing. But has 3 different parts to mix. But when I Google epoxy grout, I get a lot of negative blogs from even pros who say it is difficult to work with. What is the difficulty of working with epoxy grout?
2) Mapei Keracolor - Just add water on this one. Says it's good for even fountains & pools submerged but takes 21 days to cure for that. What do you know about this one?
3) A grout & latex additive but you will need to tell me the brand(s) and names. I'm getting blanks when I ask in the stores.
I am then leaning towards Mapei Keracolor based on what you say here and what is avalable to me. I'm no pro so the fear of screwing up the epoxy outweighs all else there.
One question on the sealing. Is it what keeps the moisture from penetrating the grout? If so then I would think it best to do and maybe redo yearly or something. Sealants all seem to specify their stain resistance but not much else.

I believe you because you're a pro. But if you talk to anyone in a store they STRONGLY emphasize sealing, saying everything from it seals out the water, stain, etc. So of course I had to ask again to be sure. I don't want another leaking shower which is why I had to rebuild this one from the base plate and studs on out.
Thahnk you for your time.
