grout dried too light

I just finished grouting my kitchen...it looked fantastic about 30 mins after I wiped it down...but a few hours later the grout is drying a lot lighter than the sample color...it's bright white, and I was going for a very light grey. Will a sealer actually darken the color?

I tried searching for others that had grout dry too light, and a lot of posts suggested TYW grout stain n seal...but the online store no longer carries that product?

What are my options?

Thanks.

Hi Rusty,
It's possible that you have efflorescence. Take a read of this article. If it is efflorescence, you may be able to etch away the top layer of lighter color and expose the real color under it. Tell us how loose/stiff you mixed the grout, how you did it, and how you applied and wiped it off. The key things we're looking for is excess water mixed initially, or too much water used on clean-up.

Thanks Kurt.

I mixed the grout exactly to the specifications - I did not add extra water.

When wiping the grout I wrang my sponge nearly dry. I don't think it was too much water during cleaning that caused the problem because piles of grout I threw out of the bucket after I was done grouting also dried the lighter color.

I think it may just be a case of the color not matching the sample. I could live with it if it were just a little darker, so if sealing the grout will do that then I could avoid any staining. The stain and seal I mentioned seemed like a good compromise, but like I said it's no longer in the store.

I've had grout dry too light--this is one reason I use Spectralock because what you see is what you get--and I use Aquamix paint sealer. The orange box store carries several colors and I'm pretty sure you can get it on the web too. It's very easy to use if it's not just a haze problem.

Hi Rusty,
At this point, why not try a solution of 50/50 vinegar & water as an etching cleaner? Try it in a small area and see what results come. Lots of times when the grout is too light, the real color is juuuuuust under the surface. I better ask before it's too late....is this a ceramic or porcelain tile? If so, good....go ahead with the vinegar & water. If this is a stone, STOP! Don't use the vinegar and water, as this may damage the surface of the stone.

This may or may not produce the desired results, but what have you got to loose? Nothing, and it cost nearly nothing to try. If it works, its less work and expense than staining the grout later.

As long as it's not a stone I would try a small area full strength. Let the vinegar sit on the joint a minute to give the acid time to work, then scrub it. Rinse well and let dry.
