Do It Yourself Kitchen Backsplash: A Complete Guide

A kitchen backsplash serves both form and function—protecting your walls from splatters and spills while also providing an opportunity to add visual interest to your culinary space. Installing a backsplash yourself can save thousands of dollars compared to hiring a contractor, and it allows you to put your personal stamp on your kitchen. With proper planning, high-quality materials, and the right tools, you can achieve stunning results and enjoy a sense of accomplishment. This comprehensive DIY backsplash guide will provide you with everything you need to know to complete this project yourself.

Selecting Your Backsplash Materials

Choosing the right backsplash tiles or panels is the most important decision you’ll make during this process. Consider the following factors as you shop for materials:


Backsplashes come in a vast array of colors, patterns, textures, and designs. Determine the look you want to achieve before shopping:

  • Color: Consider the existing cabinetry, countertops, appliances, and wall paint. A color in the same hue family will create a cohesive look.
  • Patterns: Uniform tiles in a clean-lined pattern keep the focus on your design elements. Intricate or mosaic-style patterns make more of a statement.
  • Textures: Smoother glass, ceramic, or porcelain tiles are easier to clean. Natural stone tiles add organic texture.
  • Metal: Tiles with metallic accents, or solid metal panels, add a contemporary, industrial vibe.
  • Glass: Glass tile provides brilliant color and shimmer. Frosted or pebbled glass offer soft diffusion.


Prices range from $10 per square foot for basic ceramic tiles to $75+ per square foot for higher-end materials like natural stone, metal, or glass. Measure your space and create a project budget beforehand.


Kitchen backsplashes endure heavy use—choose materials that are impervious to moisture, grease, and heat. Ceramic, porcelain, or glass tiles are very durable. Some natural stones are quite hard and stain-resistant as well.

Ease of Installation

Large, uniform tiles are beginner-friendly. Intricate mosaics and natural stone require more expertise. Grid patterns are straightforward; diagonal layouts are trickier.

DIY vs. Pro Installation

For complex layouts or challenging spaces, a professional installer may be needed. Custom cutting stone or glass should be left to experts. But rectangular ceramic or porcelain tiles can be installed DIY.

Preparing Your Space

Once you’ve selected your backsplash materials, you’ll need to get your workspace ready for installation.

Clean Surfaces

Use TSP cleaner to thoroughly wash the wall area. This removes oils and debris that could impede adhesion. Fill any holes or imperfections with spackle; let dry and sand smooth.

Remove Obstacles

Take out existing backsplash tiles or panels; pry off carefully to avoid wall damage. Unscrew wall mounted items like floating shelves. Have a plan for appliances that may need to be pulled away from the wall temporarily.

Isolate Electrical

Turn off power to outlets in the backsplash area; disconnect and label wires. Cover boxes with plastic guards to prevent moisture damage. Place draped drop cloths below.

Mask Adjacent Surfaces

Protect countertops and cabinets by covering with rosin paper or plastic sheeting. Use painter’s tape at the edges. Cover the stove or range to avoid damaging it.

Establish Level & Plumb

Snap chalk lines horizontally and vertically on the wall to guide your first row of tiles. Use a 4-foot level and carpenter’s square to ensure lines are perfect 90° angles.

Essential Tools & Materials

These basic tools and supplies are needed for most standard backsplash installations:

Tiling Tools

  • Tile cutter
  • Tile spacers
  • Grout float
  • Mixing paddles
  • Buckets
  • Tile nippers
  • Grout sealer

Safety Gear

  • Work gloves
  • Knee pads
  • Safety goggles & mask
  • Ear protection

Additional Supplies

  • Backsplash tiles
  • Thinset mortar
  • Grout
  • Caulk
  • Trowels
  • Grout sponge
  • Drop cloths

Step-by-Step Installation Guide

Once your prep work is complete, it’s time to install your new backsplash. Follow these key steps:

Step 1: Apply Thinset Mortar

Mix thinset to a smooth, slick consistency according to package directions. Apply to the wall area using a notched trowel held at a 45° angle to create ridges. Apply 1/4” thick.

Step 2: Set Tiles in Place

Beginning with your center guidelines, press tiles firmly into the thinset mortar. Push in a twisting motion to collapse the ridges and maximize adhesion.

Step 3: Build Out Rows

Work horizontally from center, setting tiles end-to-end in each row. Use spacers to maintain even 1/8” grout lines between tiles. Cut edge tiles to fit with tile nippers.

Step 4: Verify Alignment

At edges, lay a straight 1×2 board perpendicular to the last tile to check for any deviation. Make alignment corrections while mortar is still pliable.

Step 5: Allow Thinset to Cure

Let thinset mortar dry for 24-48 hours without disturbance. Mist occasionally with water to prevent cracking. Do not grout or disturb tiles during this time.

Step 6: Mix and Apply Grout

Prepare grout per package instructions. Apply grout by pressing firmly into joints using a grout float or squeegee. Drag diagonally to fill completely.

Step 7: Clean Excess Grout

Once grout becomes firm, after about 15 minutes, scrub tiles diagonally with a damp sponge to remove haze and smooth joints. Rinse sponge frequently.

Step 8: Seal Grout

After another 72 hours, apply grout sealer as a protective barrier per label directions. Allow to cure fully before using backsplash.

Step 9: Finish Edges

Run a bead of silicone caulk along all edges, seams, and transitions. Tool gently to smooth. Wipe area with denatured alcohol on a rag.

DIY Backsplash Maintenance Tips

Once your new backsplash is installed, provide proper ongoing care to keep it looking like new:

  • Use a gentle cleaner designed for tile and grout routinely to prevent buildup of grime. Avoid harsh chemicals.
  • Re-apply grout sealer annually to protect from stains and moisture.
  • Immediately wipe up any food, grease, or liquid spills to prevent possible staining. Deep clean any stains ASAP.
  • Check for cracked or missing grout periodically and repair promptly to prevent moisture issues.
  • Take care not to drop heavy pots, pans, or objects that could crack tiles. Handle cookware gently near the backsplash.
  • Consider adding a clear glass or plastic wall guard in high traffic zones to prevent damage from frequent bumps.

With the right DIY approach and high-quality materials, you can install a backsplash in your kitchen that provides functionality and aesthetics for years to come.

Frequently Asked Questions About DIY Kitchen Backsplashes

Still have some questions? Here are answers to some of the most common FAQs about backsplash installation projects:

What’s the best way to cut ceramic tile?

Use a wet saw with a diamond tile blade. This provides clean, accurate cuts. A manual tile cutter works for straight cuts. Use a grinder for curve cuts. Always wear safety goggles.

How do I get clean edges against countertops?

Run edge tiles long and use a tile wet saw to trim flush with the counter after setting. Or leave a 1/16” gap and caulk between tile and counter.

What thinset mortar is best for the walls?

Use white polymer-modified thinset, which has latex additives that create a strong, flexible bond and resist moisture damage.

Can I use regular grout for the backsplash?

No. Unsanded grout is recommended as it flows smoothly into narrow wall joints. Standard floor grout can crack in vertical joints over time.

What’s the typical height for a backsplash?

Standard height is 4 inches above the countertop, but you can go higher if desired. Building it to the underside of wall cabinets provides maximum protection.

How long does the tile installation take?

After prep work, the tiling itself usually takes 2-3 days for an average sized kitchen backsplash of 20-30 sq ft. Allow 1-2 more days for grouting and sealing.

Do I need special tools for installing backsplash tile?

Having basic tiling tools makes the installation much easier. A few essentials include a tile cutter, spacers, buckets, a grout float, and mixer paddle.
