A granite back splash can last for years without damage or fear of failure to stick to a vertical surface. Those same attributes can make it difficult to remove without damaging the tile or the wall. Granite back splash usually uses adhesive to secure to the wall. Removing granite used as a back splash often requires some repairs to the drywall before adding another back splash due to the adhesive. However, if you do it right, you might be able to reduce the amount of damage to the wall.
Cover the surfaces surrounding the granite backsplash with a dropcloth to prevent damage during removal. Secure the dropcloth in place with masking tape.
Remove any fixture covers from the backsplash. Unscrew the screws securing the covers in place and then lift the covers away.
Strip caulking from the edges of the granite. Cut the caulking with a utility knife and then remove from the edge of the back splash with a putty knife. Cut the caulking where the back splash meets the wall and the counter top.
Slide the blade of a stiff putty knife between the seam of the granite back splash and the wall on the open end of the back splash. Tap the handle of the putty knife with a hammer to begin separating the back splash from the wall.
Pull the putty knife out and reinsert it at the top edge of the back splash between the wall. Tap the handle with the hammer and continue separating the back splash from the wall.
Continue moving the putty knife along the length of the back splash and hammering it through the adhesive. Pull the back splash away from the wall completely.
Depending on the size of the back splash, it might be necessary to have a helper to assist moving the back splash. Granite is heavy and even short pieces can be more weight than one person should handle.
Wear safety goggles, a face mask and work gloves during the removal process to protect yourself from dust and debris.
