I feel like the biggest idiot!!! Two days ago, in an effort to help my husband out, I decided to grout the seams in the new shower slate that we had installed several days earlier while he was gone. I accidentally used the thin set mortar instead of the grout. They are both gray and the grout bag was no where in site! When I saw a bag that read "gray" I opened it and mixed it up. I completely finished the job and was very pleased with the results until today when I found a smaller bag that is labeled "grout" in the garage! Ahhhh! What do I do now? Will it be okay to leave it and seal it or do I have to rip it all out and start over?
