Grout Bully

The product did arrive in a timely manner, which is the only positive thing I can say. Applying it is a HUGE physical undertaking and the color fades right after you wash your floor (and yes I waited the suggested amount of time, even more than the directions say.) The advertisements on TV and the instructions that accompany the product both depict its application to the grout and removal of excess product as quick and easy. This is definitely not the case. Once I applied the product to my clean bathroom tiles I waited 2 minutes (as the instructions indicate) then tried to wipe off the leftover with the "magic erasers" which are not very magical. This stuff bonds to the surface and I had to scrub with all my might to get it off, and residue was still left behind. Both magic erasers didn't last through one application. After the grueling work of going over my entire bathroom floor, most of the product seemed to fade after I mopped a few days later. In other words, it is NOT waterproof even days after it dries. Total waste of money and hard physical labor.
