Thanks for the inquiry.
LATICRETE SpectraLOCK PRO Grout does contain UV stabilizers, but darker colors will lighten over time and lighter colors will darken over time.
I've included a link to a product data sheet for your review. http://www.laticrete.com/Portals/0/datasheets/lds6850.pdf This item is referenced on page two of the product data sheet.
I hope this information helps.

Oh I did not realize it had that much UV exposure. The UV has more than likely discolored it.On Fri, Apr 1, 2011 at 8:10 PM, Mike Marsoun <nulifesc@bigpond.com> wrote:
Thanks for the comments. The application was done properly and looked fine upon completion, the discoloration occurred after 3 months of intense UV exposure.Sent via BlackBerry® from Telstra

Installers either dont mix properly or they mix a large patch and the solids settle to the bottom of the pail. You can opt to color the grout.

I have a fair amount of experience with this grout , I have used Latapoxys on nearly every marble job in the last 18 years. I think this is what I see, some installers will not mix the entire filler material contents with the epoxy, in order to make it easier to push into small marble joints,what can happen is the heavier colorant fillers sink, leaving the epoxy to float to the surface and cure, these epoxy's alone cure to that near beige color.You might try this,mix a 50% solution of TSP and take a toothbrush to a test area to see if the grout cleans up, If not , for me latapoxy removal and re grout is just not a possibility. hope this might help.Scott / Wilson Stoneworks IncIn a message dated 4/1/2011 3:53:29 A.M.

The grout put down was Laticrete Spectralock ProGrout silver, like the sample stick. Now 3 months later, it's faded to beige.
