I distribute and install TruColor.
It performs probably better than advertised, I can't get it to stain or cause any dis-coloration / fading and the flexibility is amazing. (we poured un-diluted muriatic acid on our test board and it had no affect on TruColor
Some installation tips:
I don't recommend using a mixer, too much air and it will sag and slump
use an epoxy float, when cleaning, wipe first with a damp / but well wrung out white scrubbie, this traps and removes all the aggregate, then use the well wrung out sponge to remove the urethane haze.
It is appropriate for showers and wet areas, if you can allow it to cure for 7 days.
It is NOT a miracle product, there are applications where you should use an epoxy grout - areas subject to frequent high pressure/harsh chemical cleaning - ala Commercial Kitchens.
For the post on the product failure, my guess is the professional, experienced installer didn't use an epoxy float, over-mixed and didn't wring as much water as humanly possible out of the sponge
