Used old grout on backsplash. Discolored. Repair ideas?

I didn't realize that grout ages fairly rapidly. So, I just did a portion of my backsplash (1/8" grout on 1" glass mosaic tiles) with grout that is non-uniform in color.

I see these options:

1) Live with it. (aka, put lots of stuff in front of that particular area)
2) Scrape out grout and redo. (really hard to do and would likely chip the fragile glass tiles as I do it)
3) Go over with new grout and seal the heck out of it and hope that it holds.

Obviously, I would like option 3 to work but am aware that it probably won't. How probable is that? Since it won't be taking wear from shoes like floor grout and only moisture would be from boiling water, is there a chance that it will be okay for a while.

This is a perfect example of you don't know what you don't know.

Welcome to the forums!

Would a grout dye work?

Yes, they make a paint on grout colorant that will even out a blotchy uneven grout job. Check with your local tile shop for an array of colors that should work for you.

Good question. I don't know. This is the good.

And the bad.

It is hard to see because of the lighting, but there is uniformity in the good and light and dark in the bad. I don't know how a dye would effect that and if it can be used to lighten.

TiA,

That's great news. I will find that. And I luckily have an area behind the stove and microwave to try it out, risk-free.

Thanks.
