Granite is a beautiful and durable stone that makes for an ideal backsplash in your kitchen. If your granite backsplash has started to show signs of wear, or if you have simply decided that you want a new look in your kitchen, you can remove the granite, but it will not be an easy job. Though the process itself isn't complicated, the granite is heavy and fragile and won't come off the wall easily. You will almost certainly have to repair the wall once you remove the tile.
Lay down a drop cloth to protect your countertop and floor.
Cut the bead of caulk around the tiles with a utility knife. Cut the strip where it meets the counter.
Cut out the grout lines between the tiles using your rotary tool fitted with a grout bit. Wear safety goggles to protect your eyes while you work.
Starting at an edge, tap your putty knife or pry bar behind a tile, slowly removing it from the wall. Remove and reinsert your putty knife or pry bar along the edge of the tile until a large portion of it separates from the wall. Insert the knife or bar farther behind the tile to remove it the rest of the way.
Continue working in this manner, removing each of the tiles from the wall until you have removed the entire backsplash.
Scrape off any remaining grout from the wall, and use an orbital sander to smooth out the wall. You will likely have to use drywall compound to repair the wall.
