- Notched trowel
- Grout
- Grout float
- Grout sealer
- Caulk
- Tape measure
- Level
- Utility knife

Preparing the Wall
Proper preparation of the wall is crucial for a successful granite backsplash installation.
Step 1: Remove Old Backsplash
If there is an existing backsplash, take time to remove it completely. Scrape off any leftover debris or adhesive on the wall.
Step 2: Inspect and Repair Drywall
Examine the drywall for any imperfections like cracks, holes or uneven sections. Repair and sand the drywall as needed to create a smooth surface.
Step 3: Apply Drywall Joint Compound
Use drywall joint compound and taping on drywall seams and corners. Allow to dry completely.
Step 4: Prime the Wall
Prime all the exposed drywall with a quality primer/sealer. This provides a uniform surface for the backsplash installation.
Installing the Granite Backsplash
Now that the prep work is complete, it’s time to install the granite backsplash tiles.
Step 1: Plan Your Layout
Dry fit the granite tiles on the wall in the pattern desired. Use spacers to get consistent grout lines. Make adjustments to get the layout centered.
Step 2: Apply Thinset Mortar
Use a notched trowel to spread a thin layer of thinset adhesive on the wall area where the backsplash will be installed. Apply only enough that can be tiled in 30 minutes.
Step 3: Mount Tiles
Starting at the base, press tiles into the thinset firmly. Use a level to ensure they are aligned straight. Place plastic spacers between tiles.
Step 4: Drill and Secure with Screws
Drill holes and secure each tile firmly to the drywall with drywall screws. Be careful not to crack tiles when drilling.
Step 5: Grout the Tiles
Allow thinset to cure fully per manufacturer instructions. Mix grout and apply it over the tiles, pressing into joints with a float. Wipe away excess grout.
Step 6: Seal the Grout
Once grout has dried, apply grout sealer as directed to protect from moisture and stains.
Step 7: Caulk Edges
Run a bead of silicone caulk along top edges, bottom, and sides of the backsplash. Smooth with wet finger for a clean finish.
Tips for Installing Granite Backsplash
- Carefully review manufacturer instructions for thinset mortar and grout products.
- Arrange tiles in a dry layout before installing to ensure the best placement.
- Use tile spacers for consistent spacing and grout lines.
- Wipe any excess mortar or grout from tiles to prevent drying on granite.
- Tape off edges of countertops and walls to minimize mess during installation.

- Allow adequate time for thinset and grout to fully cure before use.
- Seal granite backsplash annually to protect from kitchen stains and moisture.
Installing a granite backsplash provides a high-end look with minimal maintenance. With proper planning and effort, you can have a stunning granite backsplash that enhances your kitchen’s style.
Frequently Asked Questions
What type of thinset should be used for a granite backsplash?
It is best to use a porcelain tile thinset adhesive to install a granite backsplash. Choose a white polymer-fortified mortar that provides a strong bond and some flexibility.
How soon can I use the backsplash after installing?
Allow the thinset mortar to fully cure for 24-48 hours before regular use of the backsplash. Allow grout to cure for 72 hours before heavy cleaning.
What’s the best way to cut granite tiles?
Use a wet tile saw with a diamond blade designed for granite. Mark tiles and cut slowly and steadily for clean cuts. Granite can also be cut with a carbide scoring tool.
Should I use sanded or unsanded grout?
For a granite backsplash with narrow grout lines (less than 1/8 inch), it is best to use unsanded grout. Sanded grout is better for wider grout lines.
How can I get thinset mortar off granite tiles?
Wipe any excess thinset off tiles with a damp sponge before it dries. Use a plastic putty knife to gently scrape off any hardened thinset. Be cautious not to scratch or chip the granite.
