Dear Tom,

I just had colonial cream granite installed. The next morning we woke to find 50 - 60 large brown spots. It has been 5 days now and the spots have not gone away. The installers would like to send a granite restoration company out. The stains are from the adhesive used during installation. They said the restoration company has some type of chemical they can put on the spots and then use a torch on them to remove the spots. Will this damage the granite or hurt the integrity of the granite in any way. I paid for new granite not restored granite, I’m not sure what I should do?

Hello Beth,

There is a lot to say about why this happened but, suffice to say, you should let them try to remove the leach marks as they mentioned. If the torch gets too close to the surface for too long it can harm the surface but you will see/feel the difference after they are done. So, let them try and if the stain does not reappear in 30 days, then the marks will not reappear.

The Colonial Cream granite is a problematic stone for oil base adhesives, and the only way to avoid this is to waterproof the back of the stone before installation. Very few installers know this, so let them try the remedy and if is works then you have exactly what you paid for. Be nice and optimistic!

Best wishes,
Tom Cordova
