How to Install Backsplash Tile in Your Kitchen

Installing a backsplash is one of the most popular DIY kitchen remodeling projects. Not only does a backsplash provide an extra layer of protection for your walls, it can also completely transform the look of your kitchen. The key is choosing the right tile and preparing your work surface properly. With some basic tools and these step-by-step instructions, you can achieve a professional-looking backsplash installation.

Planning Your Backsplash Tile Project

Before you can get started on the installation, you’ll need to make a few important planning decisions. Taking the time to think through these choices will ensure your finished backsplash is exactly what you envisioned.

Choose the Right Backsplash Tile

With so many backsplash tile options to choose from, it can be overwhelming deciding what material is right for your kitchen. Here are some of the most popular choices:

  • Ceramic tile: A classic option, ceramic tile comes in a huge range of styles, shapes, colors, and patterns. It’s an affordable choice that is relatively easy to install. Look for ceramic tiles rated PEI Class 3 or higher for walls.
  • Glass tile: For a sleek, modern look, glass tile backsplashes are hard to beat. Their polished finish provides great light reflection. The tiles are made from real glass that has been backed with mesh or a stabilizing material.
  • Metal tile: Metallic backsplashes are contemporary and edgy. Stainless steel, copper, and aluminum tile are eye-catching options. Keep in mind that metal tile requires special cutting tools.
  • Natural stone: Materials like marble, travertine, and granite make a real statement. Going with stone tile means accepting imperfections for a natural, rustic look. Stone is also quite heavy.
  • Mosaic tile: Tiny glass or ceramic pieces come mounted to 12” x 12” mesh sheets, making mosaics simple to install. Just be sure to use sanded grout to avoid filling the cracks.

Once you decide on a material, select the right size and shape tiles for your space. Smaller tiles paired with thin grout lines create more intricate patterns. Larger tiles and thicker grout lines produce a more seamless look.

Choose Your Layout

There are endless ways to arrange your backsplash tile creatively. Here are a few options to consider:

  • Basic grid: The most common layout, basic grid puts tile in straight vertical and horizontal rows. For the cleanest lines, make sure tiles are precisely aligned.
  • Brick pattern: Rows are offset by half a tile width for a staggered brick look. Use rectangular tiles all the same size.
  • Herringbone: Tiles are placed in a V-shape with sides angled at 45 or 90 degrees. Works best with rectangular or square tile.
  • Penny tile: Tiles are installed in a grid pattern with their edges turned perpendicular rather than parallel to the counter. Fun for a vintage vibe.
  • Subway tile: Classic 3” x 6” rectangular glossy tiles are aligned in horizontal rows, emulating the look of a subway station.

Gather Your Materials

Once you’ve settled on the perfect tile for your kitchen, it’s time to purchase supplies. Here’s what you’ll need to complete the installation:

  • Tile and trim pieces
  • Thinset mortar adhesive
  • Grout
  • Grout sealer
  • Tile spacers
  • Tile cutter or wet saw
  • Trowel
  • Rubber grout float
  • Grout sponge
  • Mixing bucket
  • Masking tape
  • Safety gear (gloves, goggles, knee pads)

Buy about 15% extra tile to allow for cuts and breakage. For thinset and grout, follow package directions based on the square footage you’ll be tiling. It’s better to have a little leftover than to run short mid-project.

Prep Your Backsplash Area

To achieve the best results, start by ensuring your backsplash area is ready for tile. Take these steps:

  • Remove existing backsplash tile with a hammer and putty knife.
  • Knock down any high spots and fill any holes or uneven areas with drywall compound. Let dry completely.
  • Sand smooth and clean off dust.
  • Paint the walls with primer to improve adhesion. Let dry.
  • Measure the backsplash space and draw layout lines with a level and pencil so your tile will be straight.

Proper prep prevents cracked or loose tiles down the road. Now your workspace is clean and primed for your new backsplash tile.

How to Install Backsplash Tile

Once you’ve completed the planning phase for your backsplash, it’s go time! Follow these steps to achieve stunning results:

Step 1: Apply Thinset Mortar

Thinset mortar provides the adhesive base to bond tile to the wall. Using a notched trowel at a 45° angle, apply a tight, thin layer of thinset to the wall area, covering about one square foot at a time. Spread it evenly and scrape off any excess.

Step 2: Place Your First Tile

Beginning in a bottom corner, press the first tile firmly into the thinset with a slight twisting motion. Push the tile back and forth to collapse the mortar ridges and help achieve maximum coverage.

Use plastic spacers between tiles to achieve straight grout lines. Place spacers at tile corners where 4 tiles meet.

Step 3: Apply Thinset and Set Remaining Tiles

Continue spreading thinset and setting tiles one by one. Check each tile to make sure it is level with light pressure. Adjust as needed before the thinset dries.

Periodically remove a tile and check the back to ensure proper thinset coverage. There should be no voids or gaps.

Step 4: Cut Any Custom Tiles

Measure and mark tiles that need to be cut to fit around outlets, corners, or edges. Cut using a wet saw or tile cutter. Grind the cut edge smooth with a stone. Fit custom tiles into place.

Mix tiles between boxes as you go to evenly distribute color variations. Cut edges should face the wall or be hidden against trim.

Step 5: Let Thinset Dry

Allow thinset to dry for 24-48 hours once tiles are installed. Mist occasionally with water to prevent drying too quickly. Don’t walk on the tiles until fully set.

Check for any hollow-sounding tiles that need to be re-adhered. Lift any loose tiles and apply more thinset before resetting them.

Step 6: Apply Grout Between Tiles

Mix grout with water or an additive according to package directions. Apply over the tiles, using a rubber grout float to spread it into the joints. Hold the float at a 45° angle and work in small sections.

Step 7: Wipe Excess Grout

Once the grout has slightly dried on the surface, mist the tiles with water. Use a damp grout sponge in a circular motion to smooth grout and remove excess. Rinse the sponge frequently.

Within 30 minutes, wipe diagonally across tiles with a soft cloth to remove any remaining grout haze. Buff dry with another cloth.

Step 8: Seal the Grout

Once grout has dried fully, apply grout sealer with a small paintbrush. This prevents staining and makes tile easier to clean. Allow sealer to penetrate for 15 minutes, then wipe off any excess.

And that’s it – stand back and admire your newly tiled backsplash! Proper prep and patience in following these installation steps will lead to stunning results.

Tips for Achieving a Flawless Backsplash

Installing your backsplash tile successfully depends on careful prep work, proper materials, and stellar technique. Keep these top tips in mind:

  • Always start with a clean, smooth, primed wall surface. Fix any imperfections prior to tiling.
  • Thinset coverage is key – at least 80% for walls. Check tile backs periodically.
  • Use tile spacers for perfectly straight grout lines. Place them strategically at tile corners.
  • Ensure tiles are firmly embedded in the mortar. Twist each tile back and forth.
  • Cut tiles patiently and carefully with a wet saw fitted with a diamond blade.
  • Let thinset dry completely according to manufacturer’s directions before grouting.
  • Apply grout sealer once grout has dried to protect it from stains.
  • Clean up spills and splatters promptly using a damp sponge or cloth.
  • Don’t walk on tiles or scrub grout for at least 48 hours after installation.

Follow these best practices, take your time, and you’ll achieve stunning backsplash tile results!

Frequently Asked Questions About Installing Backsplash Tile

As you embark on your backsplash tiling project, a few questions may come up. Here are answers to some of the most common FAQs.

Do I Need Any Special Tools to Install Backsplash Tile?

While you can often use basic household tools, investing in a few specialized tile tools makes the installation much easier:

  • Wet saw or tile cutter for accurately cutting tile
  • Tile spacers to maintain even grout lines
  • Rubber grout float for spreading grout smoothly
  • Grout sponge for wiping away excess grout

A notched trowel, grout sealer, mixing bucket, and safety gear like gloves and goggles are also backsplash tile essentials.

What Thinset Should I Use for My Kitchen Backsplash?

For backsplash installations, use an adhesive thinset mortar modified with a polymer additive. This will provide a strong bond on vertical walls in an area with moisture and heat.

Choose white thinset for glass or translucent stone tile. For other materials, gray or off-white thinset blends with grout for a subtle finished look.

Can I Install Tile Over Existing Backsplash?

This is generally not recommended. Existing tile is not an ideal base for new tile. It’s best to remove old backsplash completely and start fresh with a clean, smooth wall surface.

If your current backsplash is well-adhered and intact, you can tile over it, but prepare the surface with sanding and a good primer or adhesion promoter first.

How Long Does Thinset Take to Dry Before Grouting?

It’s crucial to allow thinset adhesive to dry fully – at least 24 hours – before applying grout. This prevents tiles from shifting or loosening. Pay close attention to manufacturer’s directions for recommended thinset drying times.

To test if it’s ready for grouting, firmly press a tile – it should no longer move or indent. You can also use a moisture meter to check if thinset is fully cured.

Can I Use Sanded Grout for Backsplash Tile?

For most backsplashes, unsanded grout is best. It’s optimal for filling narrow joints up to 1/8” wide. The fine texture prevents it from scratching glossy tile surfaces.

However, use sanded grout for grout lines wider than 1/8”. The sand provides density and strength to fill and cover larger gaps between tile.


With the right prep work, materials, and how-to knowledge, you can achieve a fabulous, professional-looking backsplash tile installation. Carefully follow the techniques for applying thinset, accurately cutting and placing tile, expertly grouting, and effectively finishing. Pay close attention to troweling, spacing, drying times, and cleanup.

While tiling does take some time and patience, it’s a DIY project that’s definitely worth the effort. Once your beautiful new backsplash is completed, you’ll enjoy an eye-catching, easy-to-clean focal point in your kitchen for years to come.
