Awful - Steer Clear!!!
We used Keracolor S for our mud room with no issues and it turned out fine so we figured with our subway tile shower, which has a joint of less than 1/8", we would use the Keracolor U. We followed the instructions exactly and even used bottled water to mix the grout. It looked fine after mixing and applied fine. We wiped with a well wrung out sponge as per instructions and assumed everything would be fine. However, when the grout started to dry, it started turning white instead of the greyish frost colour it was suppose to be. There was a layer of haze over all the grout and multiple pinholes! We tried haze remover as recommended on the mapei site for dealing with haze and inflorescence. This did remove some of the white but it turns out that there are also chunks of polymer and the colour is uneven regardless! After talking with a few tilers, it seems unsanded mapei grout has this problem often! Wish I knew this before we purchased it!
Long story short, the grout looks awful and now we have to spend countless hours and over $200 in supplies to remove all the grout and regrout. Not to mention that inevitably some tiles will get damaged during the grout removal process. At this point, we will never use mapei grout again! Save yourself the trouble and use a better grout like Servoperl.
