Hi All,

We recently had a BBQ built in the back garden with a quartzite counter top added.

Over the last few days we've noticed that one edge of the counter top is discoloring.

As you can see from the photo attached it runs the entire edge of this section.

I don't know if this is due to the sun or is this the adhesive traveling into the stone.

Any advice on trying to remove this would be greatly appreciated. Even if the answer is go back to the installer...
