Hang on before you go crazy on this. How long as the grout been sitting?

It was set on Monday

OK...thanks Bill...I will wait it out. Hopefully the white look will darken up to the light brown color it should be. We were really concerned being it is in a kid and dog area so we didn't want a light grout.

Bill,
After letting the floor alone, it is still way too light. The color is several shades lighter than the chip color on the brochure and the chip sample. It is in a high traffic area in the basement, plus will have our dog there too. Any advice on how to darken this. I really wanted a "brownish" color, but now I got a lightish tan/white color. I read the grout haze remover bottle, seems labor intensive, it calls for damping the entire floor prior to application. There is also a grout haze remover, than another remover that is more aggressive. What does grout enhancer do? How many shades darker does it become?

I'd say being that it's high traffic area, and especially with a dog thrown into the mix, that you might be better off with a grout colorant. It's an epoxy based coating that covers the old color completely and will give you a true color. In addition, it permanently seals the grout, and also makes it much much easier to clean. I'd give you the link, but once again, I'm on the road, and don't have my own laptop. However, if you do a search either here or in the kitchens forum, you'll find several threads where I've posted a link for Aquamix grout colorants. Check into it. Good stuff!!

Thanks Bill. Does this grout colorant actually sink into the grains and makes a permanent color, or is it a surface layer? I have about 700 square foot room, is this a big job and is it messy?

forgot to add...is this stuff what you see frequently in restaurant bathrooms when they try to cover up old grout? It looks kind of like brown (liquid nail like color) on top of the grout, it kind of looks messy a bit. Sorry for the desription, but this is what came to my head when I read your post.

It's a surface layer, but it's a tough surface layer, and it does sink into the grout.

in those same threads where I've posted the link for the colorant, in most of them, anyway, I've also posted a link to a tile forum thread where explicit step by step instructions are given in how to use it. It's not really tough, but it does take some elbow grease, and time.

I've done alot of restaurant work, but I've yet to ever use colorant in one. :-)

Interesting. My floor has white blochy spots on it. I learned to live with them. Now I am thinking I should use that coating. But does the coating wear off after time and cleanings? And is this surface layer epoxy? Do you use a paint brush to put it on? Does it wipe clean?

I think custom building products owns aquamix??
