How to Set a Full Slab Granite Backsplash
- 1). Clean any dust from the wall where the backsplash is to be placed, using a wet sponge or rag. Any dust on the wall could negatively affect the adhesive bond between the wall and the granite slab.
- 2). Place the granite slab face-down on the countertop, lined up with the portion of wall where it is to be placed.
- 3). Apply the construction adhesive in a serpentine pattern, to the back face of the granite slab, using the caulking gun. For best results, the bead should be no more than about 1-inch between rows.
- 4). Carefully lift the granite slab from the countertop, and press it firmly to the wall; wipe any excess construction adhesive that may have been squeezed out, using a wet sponge or rag.
- 5). Apply a bead of silicon caulk to the space between the wall and the back edge of the slab, and the countertop; wipe any excess caulk from these joints, using a wet sponge or rag.
