Hi all, its me again :cry:

I grouted the marble around my fireplace and it looks like the color in the grout soaked into the marble. I tried to seal the marble before grouting but being vertical I wasn't able to soak the marble like tile on the floor.

Is there a to remidy this isore? :bang:

The pictures don't show the discoloration at the grout joint as well as I see it standing in the room.

I assume you just grouted?

If so, give it a few days for everything to dry out. That discoloration looks more like moisture than pigment. Hard to tell though.

As an aside, the first granite tile work i did had a big "problem" with discoloration about 30 minutes after setting. I freaked. Didn't sleep all night either.

Showed up the next day and all was well. The moisture from the thinset had absorbed into the tile. Looked fine after drying

I was hoping it was moisture also when I first noticed it.
It has been almost 2 days now since I grouted - I think the moisture is gone.

The moisture might take longer to migrate through the tile because you sealed it

Yea, give it some more time David. I've experienced discoloration looking similar to that just from cutting the tile on a wet saw. No grout involved.

What is the longest I should wait before ripping out my hair?

A saying we use here at work is, "Hard telling, not knowing."

Drink a beer and wait a few months. No sense stressing about it now, it is what it is.

My granite tile took over a week to dry out. Give it a chance. the moisture takes awhile to move through the tile. You could place a fan in front of it and the air movement would speed it up some if you want. It looks like you used a cement based grout, but if it was a pre-mixed one, it might have stained things.

Could be a week or two. Patience, Grasshopper!
