I tiled my kitchen backsplash. I did it two sections with a window between day one and day two. There is a variation in the grout between the two sections. I realize i should have blended the packages before work, but I didn't think there could be such a noticeable difference, especially after looking at all the color chips (mapei) at the store.
Is there any way to tint the grout before or while sealing? The color is bone, one is a bit browner than the other. Any tips?
