                  The Most Frustrating Process
                  This had to have been our most frustrating project. I worked several days cleaning and attempting to seal our grout. After four applications it’s still not working. At least from what I’m understanding, the grout should be waterproof. After a quick wash with a scrubber that sprays little water, you can see the grout is still permeable, which to me, meant it will hold dirt.

                    Didn't seal grout
                    I have applied this literally about ten times. Water keeps soaking through. I thought after the tenth time, it may have finally worked. I just went to wash a small area to install a shower hanger and the grout absorbed the water.... I went to reapply (I have used the entire spray bottle on a small shower... That's how much I have reapplied this) and it's still apparently absorbing the liquid into the grout. Do not waste your money on this product. It does not work.

                      Easy spray on grout sealer
                      My daughter was pregnant so needed a low odor grout sealer to use on her shower. Product works well and is very easy to apply.

                      Did not seal my tiles
                      Followed the instructions and applied multiple coats to my basalt tile before grouting. Grout still got into the tile, leaving light specks on what should have been a solid dark gray tile. No amount of scrubbing was able to get it off. Contacted company to confirm the sealer is good for basalt, and they said it would work. Maybe the sealer works as intended for other tiles, but it ruined mine.

                        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.

                          I love the ease of use and that it is water based, i used it to seal a bridge for my bearded dragon that i covered in poly blend sanded grout. It is also easily colored to add staining if desired.

                            This product does not perform as advertised. It does not seal the grout and allows water to seep into the grout lines. Please stop selling this product as a sealer because it does not seal. Applied 3 substantial coats with 3 hours in between and the next day the water would not bead up. Waste of time and money.

                              2 coats on grout lines, newly installed ceramic tile floors. Will not bead at all, water drops still penetrate, grout still changes color. experienced contractor with 20 years, never had this bad of results.
