I would appreciate any suggestions on the potential repair. They have a granite sink. As you can see in the attached pictures, a lot of the areas have eroded out. My question, should I have the drain cover removed and grind down below the damage. Or possible skim coat the area with a tinted penetrating acrylic ? Or run?Thanks,Roger @ Restoration Stoneworks LLCVisit list archives, subscribe, unsubscribe or change your subscription preferences: http://stoneandtilepros.simplelists.com/sccpartners Start a new conversation (thread): sccpartners@stoneandtilepros.simplelists.com
