You can see the difference in this picture. The new grout is on the left and the old grout is on the right. We ran into one more obstacle...we are going to run out of grout. And we still don't know if the vacuum will make it through the whole project. Other than that, we are in good shape...about a third of the way done now. A little nervous for the handyman to come on Friday and help us with the tile in the tub. Wish us luck.
