Adding a granite backsplash to your kitchen can be a great way to upgrade the look and feel of the space. Granite is durable, easy to clean, and available in a wide range of colors and patterns to match your existing kitchen decor. Installing a granite backsplash is a project that most DIYers can tackle over a weekend. With some preparation and the right tools, you can achieve a high-end backsplash look in your kitchen.
What You’ll Need
Before starting your granite backsplash installation project, make sure you have all the necessary materials and tools on hand:
Materials
- Granite tiles or slab – Choose a granite pattern and color that complements your existing kitchen decor. Purchase enough to cover the area behind your countertop/range.
- Tile adhesive – Choose an adhesive compatible with granite that offers a secure bond, like a premium latex-modified thinset.
- Grout – A sanded grout is best for a 1/8” grout line with granite tiles. Choose a grout color that matches or accents your granite.
- Backerboard – Cement backerboard provides a sturdy base for the granite and is moisture-resistant.
- Sealant – A granite sealer will help protect the backsplash from stains and water damage. Look for one safe for use around food prep areas.
Tools
- Tape measure – For measuring your backsplash area to determine how many granite tile pieces you’ll need.
- Tile cutter – For precisely cutting the granite to fit around outlets, corners, etc.
- Trowel – For spreading the tile adhesive on the backerboard and granite pieces.
- Grout float – For smoothing the grout into the tile joints.
- Sponge – For wiping away grout residue and cleaning the tiles.
- Bucket – For mixing grout and holding water for cleanup.
- Safety gear – Gloves, eye protection, knee pads, etc. Granite can be sharp!
Preparing the Area
Before you can install the new granite backsplash, you need to thoroughly prep the area:
1. Remove existing backsplash (if there is one). Carefully detach and dispose of any old backsplash currently in place. Scrape off all leftover debris and adhesive.
2. Install backerboard. Cut cement backerboard to fit your backsplash area. Screw it securely to the wall studs with backerboard screws, keeping seams spaced slightly apart.
3. Seal and tape seams. Apply mesh tape over all seams and corners. Apply thinset over the tape with a trowel to embed it. Let dry completely.
4. Prime backerboard. Prime all surfaces of the backerboard with a thin layer of thinset or primer. This helps adhesion.
With the backerboard ready, now you can move on to the exciting part – installing the granite!
Installing the Granite Backsplash
Follow these step-by-step instructions for properly installing granite tiles:
1. Plan your layout. Dry fit tiles on the backerboard to determine the optimal layout before installation. Account for outlets and other fixtures.
2. Mix thinset. Combine thinset mortar with water in a bucket according to package directions. Let it slake for 5-10 minutes.
3. Spread thinset. Use the notched edge of the trowel to spread a layer of thinset on the backerboard, holding at a 45° angle.
4. Set granite tiles. Press the granite firmly into the thinset, using spacers for consistent grout lines. Push out any air pockets.
5. Cut any custom pieces. Use a wet tile saw (or granite cutter) to cut border tiles to fit around outlets, corners, etc.
6. Let tiles set. Allow thinset to cure for 24-48 hours before grouting so tiles are firmly bonded.
7. Mix and apply grout. Prepare grout per package instructions. Use a grout float to spread it into the tile joints, holding at a 45° angle.
8. Clean excess grout. Wipe any haze or residue off the granite’s surface with a damp sponge in circular motions. Rinse sponge frequently.
9. Seal granite. Once grout has cured, apply a granite sealer using a paintbrush or sponge per product instructions.
10. Caulk edges. Run a bead of flexible caulk along the joint between the granite and countertop. Wipe away any excess.
When installed properly, your gorgeous new granite backsplash will provide a stylish focal point in your kitchen for decades to come! Be sure to admire your handwork and enjoy cooking against this high-end backdrop.
FAQs About Installing a Granite Backsplash
Still have some questions about adding a granite backsplash in your kitchen? Here are answers to some frequently asked questions:
What type of granite should I choose?
Consider the granite colors and patterns already present in your kitchen when selecting a granite. Often a darker tone or busier pattern works best against a neutral palette. Factor in ease of maintenance too. Matte or honed finishes hide flaws better than polished.
What tools do I need to cut granite?
You’ll need a wet saw with a diamond blade designed for cutting stone. For minor trimming, a handheld granite cutter or angle grinder with a diamond blade can work. Use proper protective gear and keep granite wet while cutting to minimize dust.
How much granite will I need?
Measure the total square footage of your backsplash area, adding 10-15% extra to account for cuts and mistakes. Granite is sold by the square foot. Buy from a stone supplier, not a big box store, for the best selection.
What kind of thinset should I use?
Use a latex- or polymer-modified thinset adhesive to install granite tiles or slabs. These offer flexibility and superior bonding strength. Make sure it is formulated for use with granite.
What size grout lines should I do?
1/8-inch grout lines are common with granite tiles. The joint width should match the thickness of your tiles. Sanded grout is easier to work with than non-sanded for joints wider than 1/16-inch.
How long does it take for thinset and grout to cure?
Allow thinset to cure for 24-48 hours before grouting granite tiles. Let grout fully cure for 72 hours before sealing or exposing it to moisture. Check the product packaging for recommended cure times.
What’s the best way to cut granite for outlets?
The safest option is to have your countertop fabricator cut any holes needed in your granite backsplash piece for you prior to installation. This ensures the cuts are perfectly sized and placed.
Do I need to seal my granite backsplash?
Yes, sealing is highly recommended to prevent staining and water damage, especially around a range or sink. Reapply sealer once a year or as directed. Use a color-enhancing sealer on darker granite to keep the rich color.
Installing a granite backsplash adds instant style and luxury to any kitchen. With proper planning and care, you can achieve stunning results and enjoy this durable accent for many years. Don’t be intimidated – just take it slow and steady. The effort pays off in a high-end, head-turning backsplash.
Tips for Maintaining Your Granite Backsplash
Once your granite backsplash is professionally installed, maintaining its beauty is up to you. Follow these tips to keep it looking like new for decades:
- Use coasters under any glasses placed on the granite. Avoid exposing it to any harsh chemicals or acidic liquids like juice, wine, etc.
- Clean up spills immediately to prevent possible staining. Use a specially formulated granite cleaner and microfiber cloth.
- Reseal the granite every 1-2 years with a quality penetrating sealer to protect from stains.
- Avoid using any abrasive scouring pads or powders which can scratch, pit, or dull the surface.
- Use a gentle circular motion when cleaning the granite. Harsh scrubbing or pressure can damage it.
- Rinse the backsplash well after cleaning and dry with a soft cloth to prevent water marks.
- Inspect the caulk lines periodically and re-apply caulk when needed to prevent moisture issues at the seams.
- Consider using a granite polish occasionally to really make the colors pop if the granite has a polished finish.
- Don’t worry if your granite develops a patina or matures to a slightly richer color over time. This natural process adds character.
Following these maintenance best practices will ensure your investment in a showstopping granite backsplash remains as gorgeous as the day it was installed. Pair routine care with prompt attention to any sealant or caulk needs as they arise, and you’ll enjoy flawless, lasting beauty.
