Rated 1.0 out of 5.0 by I give a zero I hate this product it is not how I expected...I have 3 weeks that we used it and it's coming off... September 29, 2015
Rated 1.0 out of 5.0 by Difficult to clean I try it with natural stone and pebbles, not a good result, i finished sanding and polishing to remove excess September 8, 2015
Rated 5.0 out of 5.0 by Great grout This grout works great. You never have to seal it and it looks beautiful I have used it before and of course choose to use it again. Only one drawback it is expensive as it costs about $55,00 a gallon but I feel it is absolutely worth the exrta cost verses regular grout. January 27, 2015
Rated 5.0 out of 5.0 by first impression rocks! I used this on glass/stone mosaic a nd travertine and was very impressed in how it spread and packed so easily into joints. microfiber towel works like magic in making residue/haze an absolute non-issue. strength of grout is also very gives epoxy a run for the money without the hassle.

Rated 1.0 out of 5.0 by MCKEE-Shower unit We purchased the Fusion Pro grout to remodel our master shower. Home depot recommended this grout to us. We were hesitant to buy due to lack of knowledge of product but bought it because of our Home Depot sale rep.'s recommendations. We installed and within a month had a leak in the ceiling below the shower. The grout is just falling out of our walls in areas and the floor is awful. Holes just randomly appear and then spread. I contacted the Custom Builders behind the product and of course they blame my builders. Everyday is a different excuse as to way my floor is leaking. The customer service with this Custom Builders is beyond rude and has not offered to reimburse us for our troubles. Clean up and application was a messy and grueling process for my mason guy. We have two contractors that both agree that our design is not the issue. The grout color faded, the haze is saddening, and cracks are ruining my son's ceiling. So we are having to spend more money to take this awful Fusion Pro out and re-do with regular grout. Not to mention deal with the damages to the floor and ceiling from the constant leaking. PRODUCT is horrible and directions are false according to the customer service rep. We were told we should have waited a week to cure yet directions say 3 days. DO NOT buy this product, choose something else. August 20, 2014
Rated 5.0 out of 5.0 by Some really good grout The durability and easy installation is worth the price. Get all that you need though, there is some color variation between batches (typical of many products). December 30, 2014
Rated 5.0 out of 5.0 by Easiest Grout Product Ever This product cut my grouting project in half. Easy cleanup and results look terrific September 2, 2014
Rated 5.0 out of 5.0 by Great grout We have just had our installer put down 18x18 tiles, I waited for 24 hours and put in the Fusion grout by myself. You need to take your time and get fresh water in your bucket for clean up about every 10 sq ft for easy clean up. Again, take your time. June 19, 2014
