New grout, too light (gray), can I 'dye' it charcoal/black?
Hi! I've done a few searches, but I'm mainly finding info about cleaning/lightening grout, but I want to darken the grout. They just put it up today, so it's not sealed yet, and it's too light. The bathroom floors are slate (very dark gray/black) and the shower walls are porcelain that looks like slate. I'd prefer dark grout that matches, but through my own oversight we ended up with light gray grout :( I found a reference on here to Aqua-Mix, and will try to read more about that, but anyone know if I can somehow darken what I have, or maybe even put another layer of dark grout over what's there before it gets sealed?
