Very Disappointing
This product does not seal the grout. We have new porcelain tile floor and premium grout which is prudent to seal especially in the kitchen. Purchased the 24 Oz. and the 6 Oz. container with the brush applicator. Applied the "sealer" to clean dry grout and waited a day until it was thoroughly dry. Tested the seal using a few drops of water and the grout immediately soaked the water. Applied the sealer two more times over a week's time, letting it thoroughly dry and still it did not seal the grout. This water-based sealer is almost the consistency of water, drys clear but did not seal the grout. See attached pictures. Not only a waste of money but some five hours of labor to move furniture, clean the floor, and apply the sealer three times. I do not recommend this product.

    The brush is hard to use on small horizontal grout joints, I gave up and used a foam paint brush. But after 2 days of curing, I think it will help keep the shower tile clean.

    It brightened my grout to almost white!
    Bought this as I had used it before. It basically looks like I bleached my grout. I’m hoping after time it will darken a bit. I had tested it in a closet and it appeared to be fine, but after a day or so, it’s definitely brighter. Also a few reviews said they couldn’t get it out, there is a clear stop plug you have to carefully pull out. Didn’t have issues with it getting on tile or coming out clumpy.

      DO NOT BUY!
      I should have read reviews on this before buying it. I figured it would be an easy way to seal my new subway tile backsplash because of the brush! WRONG! Not only was it harder and tedious, it ruined my beautiful oyster gray grout. It made some areas darker, some lighter and left a nasty, impossible to remove white blotchy residue. So upset about this! Ruined my $500 backsplash with a $6 terrible product! Use something else, anything else! Try the spray bottle. It would be so much easier and less time consuming that the brush bottle.

        Not clear how to get it to come out of squeeze bottle
        Either I got a defective or tampered with bottle, or this is not clear how to get anything to come out....nothing comes out. I was told to cut the tip off, but the tip is a brush! I was told to remove a red spill proof plug, but there really isn't one other than the red part fo the tip on the inside which does not come out easily! I forced it out anyway with an easy-out (silly, eh!) but that can't be right. You'd think there would be some instruction or it should be obvious, or I got a defective bottle. Either way, can't say I'm happy with it. I entered a photo

          Use on Floors, not Walls
          I purchased this to seal the grout in my bathroom shower. First, note that it really cannot be applied on walls as it is too thin and runny. I worked in small sections, marking the area with painters tape. It took about 1 hour, 15 minutes for each section. I followed the directions - I applied the first coat and waited 5 minutes and then wiped off the excess (using a microfiber cloth). Then I let the area dry for another 30 minutes before applying the second coat - which was done the same way. There is no way to keep the sealant on the grout only. In the photo you can see that the brush spreads apart as you go along. Also, if your floor is sloped, it will run. It will spread onto your stone, so ahead of time you may want to test not only your grout, but your stone. It's not difficult to apply, but it is tedious. I'm not sure whether it's related, but both days that I worked with this product I developed minor headaches. I didn't notice an odor. Obviously I have to wait and see how well it works. I will try to post an update in a few months and let you know.

            After thoroughly cleaning my grout already proceeded to put on the sealer easy to use with a lot farther than I thought even with two coats most likely will use again when the time comes
