How to Attach a Laminate Countertop Backsplash

Laminate backsplashes typically are made up of a thin layer of laminate that is adhered over a piece of plywood or particle board. Laminate backsplashes can also be added to the walls behind cooking surfaces. Attaching a backsplash is the last step in the process of installing a countertop.

1. Clean and sand down any buildup or residue on the wall where the backsplash will be attached.

2. Apply thin, consistent beads of construction adhesive along the entire lengths of both the back and bottom edges of the backsplash.

3. Press the backsplash into place. Quickly wipe up any adhesive that squishes out from behind the backsplash with a damp sponge or rag.

4. Screw the backsplash to the counter to secure it. Screw from the underside of the counter (inside the cabinets) using wood screws. Have someone else hold the backsplash steady while you screw it. Drill pilot holes before screwing in the screws to prevent any splitting of wood. Place a screw every 12 inches.

5. Caulk the seam between the top back edges of the backsplash with white, water-resistant, silicone caulk. Smooth down the caulk with your finger. Dip your finger in rubbing alcohol to help it glide down the bead of caulk better.

6. Caulk the corner where the backsplash meets the surface of the counter with clear, water-resistant, silicone caulk. Smooth down the caulk with your finger.
