Saw this stuff raved about in July issue. Be careful if you try it! I talked a customer into it and am sorry I did!
Simple layout w/12″ tiles & 1/4″ grout lines. Installed as usual, which was not in conflict with instructions. Tough to clean off! Worse, arrived next day & it all shrunk and cracked. Thought I’d have to saw it out & re-apply, but called manufacturer first. They admitted to “a few issues with cracking”, but said I probably used too much water at clean-up. (Not likely.) On a hunch I called back & got another person. She suspected I got too much air it it!
Both said all I had to do was re-apply over the cracked stuff; no big deal. Only it is a big deal! I need twice as much of this very expensive “grout?” and have to invest another day or 2!
This may work for a home owner who doesn’t care about his time and it may work to go over old stained grout, but it doesn’t measure up on new installations & I’ll not use it again unless someone tells me where I blew it.
Just a warning!

I am a slab fabricator not a tilesetter but have used epoxy grout on numerous occasions instead of caulking where backsplash meets countertop and for the sink to countertop seal.
I have had zero problems/complaints. I can imagine it would be extremely messy to clean up on a large tile expanse. I always use acetone and a rag and have never tried other methods.
I am especially surprised it holds up for the sink to countertop seal over time. I figured the sink would move due to temperature changes and break the seal but the oldest is 3 or 4 years old with no complaints.
The reason I used it on the sink seal is that caulking always gets so grungy looking over time and the epoxy grout is very easily scrubbed clean.
I use C cure brand and it is a chore to mix if cold and can cure rather quickly in hot weather if left in a large mass (ie. bucketfull).
Sorry to hear about your misfortune but I am not even sure yours was an epoxy.

Thanks for the reply, Karl. No, it's not epoxy. Used that with great results. This is a new product by TrafficMaster and 3M Scotchgard. Customers will find it because Home Depot now carries and promotes it.
I wuz wondering about that stufffffffffff.
Epoxy is a bitch, but it works. It's expensive too.
Plain ol grout mixed with admix instead of water works good, seems to resist stains and no other problems I know of.
Guess I'll stick with that until something better comes by. Doing it twice due to cracks doesn't sound like fun.
Thanks for the heads up.
