Help! New grout color uneven


I have the same problem with the mapei grout, as do many other people online if you research it. I think Mapei should at the least refund us for the grout, and possibly for the reinstall on the grout because it's extremely expensive. Another option is for them to provide a grout colorant and labor for the install. They ruined my beautiful basement install with uneven grout. I got it at Lowes- three bags. The whole floor is uneven, so it's clearly not variation between bags. It was supposed to be light brown but it has every color between brown and white, a lot of it white. This is horrible!!! I spent $2000 for tile floors and it looks worse than vinyl. Mapei needs to come clean instead of continuing to ruin people's homes. Any lawyers out there want to go for justice?

Help! New grout color uneven


Sorry to hear about your grout issue. The problem might also be the color choice.
I recently had TEC light buff grout installed. It's kind of a light taupe/brown color on the chart. It turned out to be whitish in areas along with grey and brownish areas. Very strange.

I wonder if anyone knows of a grout color that might be the safest / consistent color to use. I mostly read about the light browns having the varied issues. Since I am re-grouting I dont want any issues with this again. Our tile has a yellow and beige tone to it. Perhaps a beige color from TEC is what I will use and see what happens. I'll test with some extra tile pieces first as well; which I didnt do the first time around.

Do the instructions recommend that you mix the entire contents of the package dry before mixing any portion of the package with water?

Has anyone read any of the instructions that come with the product?

Hate to say it, but you are probably right Bud. I'm pretty sure that the 25 lb bag used to grout my floor was not dry mixed entirely before mixing the grout with water. It also looked like the installer was using quite a bit of water to clean it up as well. LIVE AND LEARN I guess.

I find it funny that people will spend more time looking for solutions and whining and complaining than it would have taken for them to read the directions in the first place.

Question

Help! New grout color uneven


It's been one week since I had 530 sq ft of tile applied. Tile installer very experienced, has approx 30+ years of experience, plus 2nd generation installer.
The grout chosen is a Mapei, maple color. Has dried very uneven color, within each line of grout significant variations from almost white to maple. Majority of grout is lighter colored than maple.
Have attempted to wash it, thinking that lighter color could be residual haze, may have improved color by 5%. When grout was wet it looked perfect. Also tried vinegar wash, this did not make a difference, looked great while it was wet.
Checked out the Mapie web site. They give NUMEROUS reasons that grout can dry with an uneven color, including temp, water mixed unevenly, water with too much chemicals in, and many other reasons. Someone actually suggested to buy bottled water to mix with the grout.
From my experience and the other posts I have read that I would not suggest using Mapei grout, especially colors in the medium color range. the color I used was maple, similar to taupe.
I have sealed one smaller area with aqua mix gold sealer, thinking that sealing it may give it an even color. While it was wet looked perfect, but when dry again uneven color.
QUESTION, Does anyone have experience with either of two aquamix sealer products; 1. stone enhancer 2. enrich and seal. I am hoping one of these will give an even color.

Sorry to hear your grout issue Hindsight1. I was in exactly your shoes a couple months ago and all I can say is to try and breath and relax. From my experience there really isnt anything you can do at this point that will make you like the grout if it's not satisfactory by now. Trying acids and other chemicals probably will only make it worse.

Grout colorants arent a bad choice, but you could do what I did and remove the grout and re-grout a second time. It would be best to remove the grout within the next 2 weeks before it really cures strong. I wound up digging out 400 SQ/FT of grout after it cured 100% (after 28 days). This made it a little harder on the hands to remove all that grout. However, It took about 4 days total and I couldnt be happier with the TEC sand color I chose. A manual grout saw and a few days off from work was my answer.

Question: Was any additive used or just water added to the grout when mixed ??? Also, what kind and size tile ? Is it rectified tile ? All these things can help make a decision to re-grout if you are unhappy with it.

You are joking, right? Why would a clear sealing product change the color of grout?

Take it out and start over. That's your only real hope short of using a grout colorant.

MR BUD, Your response was a joke, RIGHT?
The reason I thought enhancer might work is because when the grout is wet it all is exactly the same color. I thought an enhancer might have an effect like furniture oil, giving an even appearance to wood.

Not really intended to be a joke actually. True that enhancers can enhance colors and bring out the richness of a stone while at the same time maintaining the natural appearance of the stone and in some cases delivering a lasting "wet look", sorta.

When installed over grout it would do basically the same thing. Whatever color exists before the application may well exist after the application but may be enhanced. You wet the grout with water - it changes colors favorably but returns to the undesireable color(s) when the water dries.
You wet the grout with the enhancer and the grout also changes color favorably. The question is what will happen when the enhancer dries.

No where on the label (that I am aware of) or in the claims does it say those products are "grout color evener outers".

Worst case scenario is that you would have to remove the grout and start over. So.........why not try some enhancer and see what happens? If the results suck, you know what your next course of action will be.

Give it a shot!

Listen to Bud Hindsight1,
I was in exactly your shoes a few months back. I mean exactly.

The answer, well I wound up bothering the heck out of Bud with a ton of questions and he really has the experience. You can trust what he says.
I tried experiements with enhancers, colorants and acids. All of it was a waist of time. I should have removed the grout immediately and saved my self a lot of grief. I couldnt be happier with the results now after re-grouting.

The key: Just go slow and remember there is light at the end.... you know the saying. Coincidently I originally used a taupe color as well, but from TEC. I dont think the manufacturer was the issue. It might be wise to choose a different color as well.

"Tile installer very experienced, has approx 30+ years of experience, plus 2nd generation installer"

Just curious, what does your experienced installer have to say?
Sounds like someone like this would have seen the issue before.

My guess is that an additive (maybe the wrong one) was used and/or too much water was used during cleanup. The least amount of water used during clean up should probably yield the best (even) results.

Excellent point!!!
Any installer that has never before seen this issue just doesn't really have that much experience would be my guess.

Help! New grout color uneven


I recently installed over 3000 sq.ft of 16 x 16 porcelain in the addition of my church. I did some research and thought that TEC's Next Generation grout would be a good choice, stain resistant, mold resistant, and didn't need to be sealed. I picked the darkest brown color they had, almost the color of dirt.

I let it cure for almost a week, and it never dried evenly. Many of the grout lines were almost white! It is a mess. I called TEC and they recommended that I try an acid wash, so I used their "Like New Grout Cleaner". I used it on a small area and it worked. I wondered if it was the XT grout, so I switched over to the regular TEC grout and it dried evenly.

The way I see it, this is a grout issue and don't believe that I should have to fix it. I received 3 estimates from grout cleaning companies ranging as low as $1700-$4,400 to clean it. I submitted a claim to TEC and am waiting to hear what they are willing to do to resolve the issue.

Try TEC's Like New grout cleaner. Mix it with water (50/50 solution). You have to scrub the grout line with a course brush, let is sit for a minute, then rinse with water.

Hope this helps and God bless,

DC Tile
