Epoxy Grout...specifically CEG-Lite
I only have grouted tile 3 times twice with cement based grout and yesterday with CEG-Lite epoxy grout.
Based on my experience I will never use cement based grout again. In my opinion/experience it is harder to mix and too easy to dilute the color during the clean-up phase.
The CEG-Lite grout that I used yesterday was basically fool proof. It is much easier to mix than cement based grout. I mixed it in the hallway outside of my bathroom with no dust or mess and in about 5-10 mins tops. The clean up does not get any easier, just use plenty of water and clean the surface of the tiles in a circular motion.
I ended up only using half of my first container because I was concerned about making sure I did it correctly. I actually ended up doing more than I had planned on with my first attempt with this product due to ppls claims that epoxy is hard to use and hardly having any experiences posted on CEG-Lite. Not sure how SpectraLock is but if it is easier than CEG-Lite then there is not much of an excuse not to be using epoxy based grouts on the bathroom or kitchen floors.
The end results is a very smooth kind of sheen/sparkle look, consistent color (which I never got from the cement based), and it is very hard.
The only negative I encountered was the surface of my tile ended up very sticky. I then got some hot water and some grout cleaner, then distributed water across the face of the tile, then poured some grout cleaner directly to the tile surface and scrubbed with the white scrubbing pad and then dried with a micro fiber towel. I was worried that this was going to be a big issue...nope cleaned it right up and this was performed about 6-hours after installing the grout. I dont think I could do that with cement based grout.
This stuff was ridiculously fool proof.
As a result I will be doing the tub surround with it as well.
Me as a home owner doing it myself am not concerned about the additional cost of the epoxy grout vs cement based. I am more concerned about the results. I am already saving money by not having someone come to my house and do the work. Why not spend more money on something that will continue to look good without having to seal.
DONT BE SCARE TO USE THE EPOXY...I ACTUALLY REGRET NOT USING THIS FIRST DUE TO ALL OF THE NEGATIVE EXPERIENCES POSTED...I am assuming that these products have come a long way and you can not base post from two years ago on what is available today.
