Granite Counter Tops Leaching Green Stains
I am having a problem with granite counters. We have had them for four months. Green is leaching through on edges, near seams and on top. The granite is Golden Splendor. Thanks!
The green granite stains you are seeing near the seams, etc. are almost certainly from the adhesive used to glue the countertops down and the seams together.
This issue seems to be associated with accelerants sometimes used with the glues.
Typically the stains show up more quickly, and can be difficult to get rid of. They can be permanent since the source cannot be removed and just saturates the granite.
Your only hope, besides tear out and start over is to try and get the stains out following the instructions in the Removing Granite & Marble Stains ebook
You'll likely have to repeat the process over time, but it's often effective.
