Question: Though it's not intended, can this be mixed in the grout before grout is applied?  If not, can anyone suggest good product meant to be mixed in?
Document: This is advertised as a low-VOC (low volatile organic chemicals) product, but the fumes made me ill even though I had windows open. And we were sealing grout -- not tile -- on an area only about 7' x 7'! When we use this next time, we will not only have the windows open; we will also have fans running.The product did leave the grout looking good, however, and didn't change the grout's appearance.
I can't imagine how anyone who personally applied this product would write that it does not smell. The label says low VOC but it's  the most toxic product that we have ever used. I applied it to a small bathroom floor 4 x 7' with an open door and fans running and the fumes made me very sick- and the fumes won't let up. I'm sure there are more human 'friendly' products that work just as well or better. This sealer should come with a very strong warning.
I used a OXO Good Grips Deep Cleaner Brush to scrub the grout. The cleaner and brush both worked very well. I wiped the tile and grout with a clean wet sponge damp with water. The next day I applied three coats of sealer allowing at least 30 minutes or more between each coat. I blotted the excess sealer with paper towels. A microfiber towel easily buffed off any sign of the sealer on the tile.
First, lets get this out of the way. I used the product correctly. I put on excess, let it sit, and then wiped off excess. Since it was a shower, I did this twice. On the floor of the shower it doesn't seem to seal the grout very well. I have a bunch of this stuff left and I'm redoing some tile. I'll try it again and update this post if I can give any more info good or bad.
I hate grout, I hate laying it, I hate cleaning it, I hate sealing it. We recently went through a bathroom remodel and I wanted to get a very high quality grout sealer. I looked around and this brand is considered the best in the industry. So far so good, it has been a year and I have had no mold and no water issues.I would recommend this product to others.
Considering the price, the product is okay. It is thicker than the most expensive one I got from Home Depot, which I was told was used by professionals, but which was much cheaper than Aqua Mix Choice Gold. I applied 2 (thick) layers on the grout and 1 (thick) layer on the tile. I feel a wax-like layer on the surface, but not really dirt or liquid repellent. The label says it will last 13 years.
We have no problem with the vendor - the item was delivered on time and in good condition. However, I feel that I must comment on the product itself. We purchased this product based on the recommendation posted on National Tile Council Association (NTCA) website. Big mistake! It does absolutely nothing for the travertine tile we have in the bathroom. As a matter of fact a 50% cheaper sealer available at Home Depot does a much better job than this overpriced lemon. Beware!
I applied three coats to the grout. Easy to apply and low odor. Time will tell if it last 15 years.
This sealer was easy to apply to grout with a toothbrush. Went on quickly and easily. After applying sealer to one grout line, I tested it by pouring a few drops of water. On the sealed grout lines it made a bead, whereas the unsealed grout lines absorbed the water. So far so good, I hope it lasts!
Used this on back splash grout in kitchen, shower wall and floor grout in bathroom and master bathroom floor. Worked really well for all of these cases. Did two applications one day apart and grout seems well sealed. Only been on for a month or so at this point, so can't testify about how it works long term, but so far so good!
