Fusion Pro Single Component Grout should be allowed 24 hrs. until light traffic, and 7 days at 70° F (21° C) and 50% relative humidity before intermittent water exposure (such as a shower enclosure); Lower temperatures and higher humidity will slow the cure times.

                  fusion pro, first time
                  Just did 160 sq of 12x12 tile. debated on what grout I was going to use and then they put the fusion pro on clearance for $18 a gal. With that much of a discount, I figured I would try it. No doubt, it dries FAST. I started with maybe 4 tiles (3 sq) just to get a feel for it and then got up to about 8 sq (give or take). I like the way the joint hardens fast because I have a tendency to pull to much out of the grout line. It definitely hardens even faster on the tile. I gave myself an edge and used the grout release an hour before grouting. I have to believe that this helped a great deal. I did have some haze and went back 2 hours later and took off what I could see with a heavy duty kitchen scrub sponge and water. The grout lines were rock hard (I like that). Fusion pro is NOT for everyone and certainly not for a rookie. I liked working with it. It's not something I would pay retail for. I can do just as well with cement base. Time will tell if this stuff is any more durable.

                    Color not properly mixed
                    Found chunks of blue dye in the pail that were not mixed in properly. I had to go back and rework some of the grout lines where the blue showed. At over $70 a pop I'd think they could do a better job mixing the colors.

                      Read Instructions and you won't have issues.
                      I encountered some difficulties using this grout. The product started to break apart during application. However, I was putting too much product on the grout float. It is important to read the instructions carefully, especially if you are a DIYer. I found a useful tip online - before grouting, clean & wax each tile first, which not only reduced the cleanup time but also gave the tiles a glossy finish. For me, Fusion Pro is still worth using compared to others due to its many benefits.

                        Beautiful neutral grey color. Worked perfectly with our slate tile floors! My husband was impressed with how easy it was to apply too. The final product is lovely.

                        Does not harden.
                        I am not sure why but my grout in the wettest parts of the shower floor is coming out. it is soft and mushy like plumbers putty. I let it sit for several weeks before use. I called the company and they are no help. I google the issue and found several people have this issue. the install was done by a contractor. I will have to scrap out all the Fusion pro and replace with something better.

                          This was perfect lightest grey to go with my white and gray quartz counters . Also. it went with white, marble and glass backsplash tile much nicer, more softer than if I were to use white grout

                          Mutes tile color
                          I typically only write reviews when something is awesome. I bought this product and disregarded other reviewers assuming they had misused the product. They did not, went slow, only did 2 square feet of my newly laid marble wall tile, sponge, clean water and STILL ended up with haze. We tried buffing it didn’t help. Haze remover did shine them up kind of but did not bring back detail/color. See pics for difference in color, vibrancy of tiles grouted with normal grout on main wall vs skinny strip.

                            Hard to use but
                            I used this a year ago when grouting stone in my shower. I followed all directions, they say it's easy. I found that it sets up very quickly, luckily I did small areas. And it's very difficult to clean up, lots of wiping! Then 2 days later it was still soft, I waited about a week. I thought either the product is no good or I screwed up by wiping to much. So here is the main point, it dried super hard, looks great, no mold issues, no staining issues.For stone you must seal before grouting.
