Thank you Fred, what about how long it takes to appear? Can it happen within minutes?

in order to understand why certain silicones, acrylics and other adhesives absorb into the stone one has to remember that many of the carriers of these glues are oil based. What does oil do in porous stone? it absorbs. So it is really not breaking down, its being absorbed into the stone. This is why it is important to chose the right silicone. Typical I like a 100% clear silicone. Stay away from the colored silicones and the acrylic caulks as well. The methylene chloride will break the silcone down which is why it is important to remove the silcone from underneath

Unless you can remove the silcone under the countertop it may not be able to be removed. If you poultice you will continue to pull silcone through. I would have the fabricator remove the countertop, scrape as much silicone as you can off and than use a poultice with methylene chloride..Find out what type of silicone was used.

I found out that it was definately silicone used. 2 questions, what type of poultice should I test with, and how long after installation should this stain begin to appear. I ask because my client, the stone store, is trying to figure out liability and he said his client is claiming to him that it was there just after they finished. Does it stain that quickly?

Lorne,

It could be they used a silicone to hold the stone in place the he material
in bleeding through the stone. It may not be a continuous if the silicone
was only spotted in areas to hold the stone. Find out from the installer
what they use to hold the stone in place. If they used a silicone and it
bleeding through the stone then you going to need to remove and replace the
silicone and probably try to poultice out the silicone that in the stone.
it's possible this could not be fixed and a new stone may need to be
installed.

I was wondering if anyone had some thoughts about what is causing the
darkness on the stone in these pics. It is a fairly new installation of
quartzite. In the time since it was put in, the dark areas have begun to
appear. The person who brought us in has already had the installer, someone
who got the stone, and the company whose sealer they used to look at this
and no one knows what caused it or how to correct it. I thought that maybe
it has to do with the adhesive used? Although it does not go entirely around
the perimeter. Some areas there are only small spots. I also need to know
how I could attempt to correct this.
