                  Summarized by generative AI from text of customer reviews

                  Customers say that Prism grout is easy to mix and apply, with many appreciating its color consistency and the fact that it does not require sealing. However, users have noted that it sets quickly, which can lead to challenges in application if not managed properly. While the product generally performs well, some customers experienced discrepancies between the color on the packaging and the final dried grout, leading to mixed satisfaction regarding color accuracy. Overall, it is viewed as a high-quality option for various tiling projects.

                  Inconsistent and blotchy
                  For a more expensive grout I expected more. Went on nicely but the color is inconsistent and does not dry as dark as expected.

                    I am a 25 yr. pro tile tech & followed the directions. Grout mixed well, spread well & cleaned up well. Once dry however, the color is inconsistent & "speckled". Do not recommend.

                    Color WAY off
                    We got DeLorean gray because it matched the colors of the tile and we wanted the grout to be seamless and not stand out. The grout has ruined our bathroom. It’s way way lighter than what’s on the box. Prism needs to take some accountability for this as there’s tons of reviews stating the same. I am kicking myself that I didn’t read the reviews first. A very expensive bathroom ruined when we are this far along.

                      Actual color did not match box
                      Caution!! Followed directions, used distilled water, mixed amount for a shower floor. Short working time, but it applied well & cleanup was good. Purchased Delorean gray, but when dry, was much lighter. Matched to Rolling Fog, 2 or 3 shades lighter, from the Prism color chart. Color was uniform and consistent, but the wrong color. Not what I wanted. Save yourself some frustration mix & color check it. Other reviews state the same problem. Next time, unless it's white, I’ll pick another brand.

                        Color isn’t anything like the color on the box
                        I’ve done lots of tile projects before, never had an issue with grout color being so different from the box. I used pewter, after holding the tile close to the box. Was looking for the grout lines to match the tile, within reason. I followed all of the directions completely, I waited the appropriate times between steps, and wrung my sponge out well before cleaning the haze. The lines look great, but much different than pictured on the box

                          Definite Efflorescence or Wrong Color in Box
                          For a product that says "no efflorescence" on the front, it absolutely turned from Delorean Grey when mixed to the whitest grey I have ever seen despite following instructions to the letter. Other possibility is a mix-up in which color grout was put in the box. It's lighter than Rolling Fog. One star for color consistency being wrong, but equal throughout, I guess. The 50% MORE should be for time spent removing/fixing this.

                            This color came out nothing like the picture nor the sample stick!!! SUPER WHITE color with now creamy biege color like pictured on sample card. Do yourself a huge favor and test it on a set of tiles before using

                              First time user and went fairly well
                              It applied well under the short time frames considering other comments and the following: 1. Do not use tap water because it has chlorine which lightens your color. Use cold (refrigerated) distilled water so its workable longer 2. Mix by hand only what you can work in short time i.e., one wall at a time 3. Does contain sand so be careful on polished tile by wiping before it gets to dry. 4. Can add more water but too much is not good. 5. Sealer is not needed but instructions says otherwise?
