Rated 3.7 out of 5 by 138 reviewers.
Rated 4.0 out of 5.0 by Worked Great I've never used grout before on anything. I decided on Fusion Pro "bone" color grout and purchased it at HD. Later I noticed a lot of the negative reviews on here saying how the grout "never hardened", etc. I was a total NEWBIE at this process but I watched the how-to videos on YouTube, took my time, and it all worked out fine. FYI - I applied this to vertical shower tile. Based on my experience, here are some tips: 1. Keep the surface wet. Lightly pre-wet the surface, apply grout with float until it just begins to harden, then use a medium-wet sponge and wipe off excess. This not only helps remove excess but keeps the grout wet. **The grout needs to be wet in order to harden correctly. ** 2. Buy 2 buckets and keep them full of water. Have a helper rotate the water for you while you're grouting. 3. Focus on a small area at a time. I did roughly 3'x2' areas. 4. Use several microfiber cloths to wipe down tile after you complete step 1. 5. If you're doing a wall, lay down some plastic sheeting or cardboard to catch any excess grout that falls. This will help with cleanup later. I can't speak to the longevity of this product as my bathroom project isn't complete yet. But I followed the steps outlined above and it looks great so far. Again, I'm not a professional installer. This is only my experience but I hope it helps! March 28, 2015
Rated 5.0 out of 5.0 by Fantastic Product This is likely the best grout I have ever used. It spreads easily, cleans easily, and is durable - if you follow the directions. And as an epoxy based grout it adds strength whereas traditional grouts have no bonding strength. And because it is pre-mixed in a closed bucket you can do small sections at a time without worrying about the grout setting up. The only down side is the 3 day drying time. However, with regular grout you need to wait 48 to 72 hours to seal it then add another day. So I guess its a wash. June 30, 2015
Rated 1.0 out of 5.0 by Worst product ever!!!!! Stay clear of this product! I was talked into this product my multiple sales reps and have never been so disappointed. My installers did two jobs that day. One with this product and one with regular sand grout. The Fusion left a terrible haze on the tiles. I called customer service and they're familiar with the problem and told me to purchase a cleaner. I did and it didn't work, just wasted more time. The cleaner started to pull up the tile grout lines. I ended up ripping up the tiles and replacing them with new tiles using a different grout. In case you're wondering the other job that was done with regular sand grout came out perfect. Do yourself a favor and stay clear from this product. You'll save yourself time and money! May 5, 2015
Rated 1.0 out of 5.0 by Totally Disappointed -- Turned Dingy Yellow Within 2 Weeks! I was SO looking forward to using what I thought would be a superior grout for my 2 sons' shower. What drew me to this was the non-mildew and epoxy-like properties, but we now completely regret using this grout. Within 2 weeks of installation, the grout joints have completely yellowed! I have tried bleach to no avail and now the beautiful 12x24 bright white tiles we installed are tarnished with this horrible yellow-ish grout. *** It is worth noting that we also used Fusion Pro Delorean Grey on the floor, which actually turned out beautifully. My only advice is steer CLEAR of this "Bright White" disaster, which is anything but white! January 14, 2014
Rated 5.0 out of 5.0 by First and only grout I had heard about this product while shopping for tile, and the benefits seemed to be too good to be true. When it came time to finish off my tile project, I was looking to wrap it up with less steps but still get the durability and appearance I wanted. This grout was easy to apply, with no difference spreading it like other grouts. Clean up took a little bit longer than I expected but still looked great and sealed up nicely. February 5, 2015
Rated 1.0 out of 5.0 by avoid, steer clear. what a waste of time this product has caused me. its awful. as a professional I should have known better and stuck with the usual sanded grout for a shower. I was assured by the rep at Home depot this was the trick for a shower floor.. I've done countless showers in my career and this product has been not only a waste of money but also now have a very un happy customer with her grout failing. July 14, 2015
Rated 2.0 out of 5.0 by Buy the Cheaper Product! I was told that this product does not stain or wear easily, and that is a bunch of bunk, my husband had gone into our bathroom wearing his slippers, and the grout had scuff marks. I wouldn't waste my money on a product that does the same thing a cheaper product would. July 7, 2015
Rated 5.0 out of 5.0 by I now will not use anything else! This product is amazing! When customers would ask me to do normal grout in lighter colors (especially white) I would refuse and tell them they would not like me in a couple of months if I did it in white. I was a skeptic, but this stuff really works, even with white grout! I waited 9 months before writing this review to see if it held up, and it is has held up so well! The customer is a friend of mine and has 4 kids. The kids have colored the grout with crayons and marker and they came right up with no hassle! There hasn't been any discoloration at all and it was put in very high traffic areas of the home. Those people with negative reviews must not have followed directions to putting this down and using the tips and tricks to make the installation easier. I recommend 10-15 square feet max before thorough cleanup of the grout. CLEAN UP AS YOU GO AND YOU WON'T HAVE PROBLEMS! This is epoxy people, so when it dries, it is a beast to clean up. Light traffic after 24 hours and 3 days before it sees water, then you are good. What is great is there is no return trip to seal it. Contractors and professionals, follow instructions and you will love this grout, and your customers will love you and bring you back many times for more rooms and your work will earn word of mouth referrals. I will now not be using anything else when working with ceramic or porcelain. Natural stone tile I will still use regular grout because the stone will need to be sealed anyways, but for anything else, this is my go to. July 13, 2015
