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

Subject: [sccpartners] quartzite staining

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.
