              Q:My tiler used the Oyster Grey Prism Ultimate Performance Cement Grout for my kitchen floor and backsplash. What could be causing it to feel chalky to the touch and visibly wipe away with just water? It also absorbed oil behind the stove.

                      Color doesn't match- BONE
                      Another disappointed customer. Product was supposed to be BONE, it's drying to a light grey color. Terrible coloring. Should have read the reviews first and used the Mapei universal grout product instead.

                        I being trying to get customer service and they just put you on hold for hour. I bought this for my subway tile . I wish I would just listing to what people said I. The comments. I following the instructions to a t. Mix the one bag. Use my measurement cup. Mix it for 5 min. Let it set the hold 9 yard. This stuff dry up so fast in my bucket . That was a whole pack just about lost. This is crazy. They just took my money like this and not answer there phone to tell my why. A big wait cost me money

                          Beware
                          I wish I had read other reviews first before deciding on the bone grout. I went back n forth trying to pick a color that wasn’t too light since I was concerned about it getting dirty but wanted a cleaner look. I chose bone because it is supposed to be a pretty beige but it dried white. Depending on the lighting it doesn’t look as bright, but it is white. I am extremely worried about the upkeep but I’m now stuck with it. Although it doesn’t look bad with my tile color, I preferred a more blended look. I truly wish I would have chosen a darker color.

                            We purchased this because the local store was out of the mix we’d used on most of our tile flooring install. It was a non sanded grout and I wasn’t familiar with it. It set up quicker and was harder to clean than the other product. For an experienced user it’s probably fine.

                            Worth the extra money!
                            First time using Prism and it was fantastic. Mixed easy and love how it comes in 2 bags so you know you’re mixing exactly half. I’ve had color consistency with every colored grout until using Prism. Like others say it does dry quickly so don’t mix up more than one bag and don’t get too far ahead of yourself before you wipe it off.

                              Works well but isn't as dark as shown.
                              Work well but is lighter than the color shown. I was really looking for a darker color. I really wish it had been the same color as on the box.

                              Great Grout
                              We used Arctic White to blend with our bright white tiles. Just what we needed. We didn't use as much as anticipated. The nubs on the tiles provided for a small grout line. We mixed up 1/4 of one bag at a time (2 bags are included in each box). The job went well by following the instructions on the box.

                              Outdoor grout mix
                              First time to use this brand of grout, but if I do more outdoor tile, this will definitely be the product I use! EZ mix, superb consistency!
