PLEASE HELP QUICK grout yesterday - seal today - is it safe?

If there is anyone listening - please give me a straight answer. Should they do it as quickly as that?

Please have a look at my question last Sunday - I would really appreciate someone giving that a quick glance. If the grout does look dirty after they seal it, is there anything easy we can do to get the seal clean again before re-sealing?

Have a look at what it says on the sealer bottle. I'd have thought that 3 days would be more appropriate to let all the moisture from the grout.

dont seal over dirt, clean it with drain cleaner acid and water, may take off a bit of grout, but that can be reapplied easy enough. then seal the grout lines when all is dry.

Thanks for that, I'll remember that we can do that if really hate it.
Does the sealant always change the colour? I really liked the limestone with my very pale tiles, now the grout is a rather nasty beige.
