What Do I Need for Backsplash Install?

Installing a backsplash in your kitchen can transform the look and feel of the space. However, there are several considerations regarding what you need for a successful backsplash installation. Proper planning and having the right materials on hand will ensure your project goes smoothly.


A backsplash serves both decorative and functional purposes in a kitchen. Made of tile, metal, glass, or other materials, a backsplash sits on the wall behind a countertop, range, or sink. It protects the walls from water damage, grease, food stains, and other types of wear and tear. Backsplashes also allow you to add visual interest to your kitchen decor. With so many design options to choose from, it’s easy to find a backsplash that matches your personal style.

Installing a backsplash is a manageable project for many DIYers. With proper planning and preparation, you can achieve professional-looking results. This article will cover everything you need to know to successfully install a kitchen backsplash yourself. We’ll review the necessary materials, tools, and steps involved. Knowing what to gather ahead of time and understanding the installation process will set you up for backsplash success.

What Type of Backsplash Should I Install?

Before diving into the installation requirements, you’ll need to decide on the type of backsplash material you want to use. There are several popular options to consider:

Ceramic or Porcelain Tile

Glazed ceramic or porcelain tiles remain one of the most common choices for kitchen backsplashes. They come in a vast array of sizes, shapes, colors, textures, and patterns to suit any design aesthetic. Tile backsplashes provide a durable, easy-to-clean surface.

Natural Stone Tile

Backsplashes made of granite, marble, travertine, or other natural stone tiles create a sophisticated, high-end look. The veining and colors found in natural stone make each tile unique. However, these materials tend to be more expensive. They also require extra sealing to prevent stains.

Glass Tile

Glass tile adds brilliant pops of color and shine to backsplash designs. The transparent, reflective material gives off a luminous, eye-catching effect. Glass tile comes in various shades and shapes. It provides a modern, sleek appearance.

Metal Tile

Metal backsplashes bring contemporary industrial flair to a kitchen. Tiles made of stainless steel, copper, tin, and other metals infuse cool, sleek style. Metal options like tin ceiling tiles provide charming vintage character as well.

Mosaic Tile

Mosaic tiles feature tiny, closely-arranged tiles that form an intricate mosaic pattern. The small tile size allows for creativity and detail. Mosaic backsplashes deliver visual impact and artistry.

Once you select your backsplash material, you can gather the necessary supplies and tools for installation. Carefully planning out your design is also essential. Keep reading to learn everything you need to prep for and successfully complete your backsplash project.

Planning Your Backsplash Design and Layout

The layout of your backsplash influences its aesthetic appeal as well as how challenging the installation will be. Spend time planning the backsplash design and tile arrangement before purchasing materials and starting the project. Here are some layout factors to consider:

  • Backsplash Height: Standard backsplash height falls between 4 and 6 inches above the countertop. However, you can install it higher or lower based on your preference. Consider the existing wall space and cabinets when determining the height.
  • Pattern and Design: Sketch out the tile pattern and overall visual design you want to achieve. Mixing different size, shape, or color tiles can create intricate patterns. Accent tiles can be used as borders or banding as well. Plan how tile pieces will fit together.
  • Focal Point: Identify a focal point, if desired. For example, use a decorative tile piece behind the stove. Complementary mosaic tiles also make an appealing focal area.
  • Function: Make sure to account for the functional spaces the backsplash must protect. Fully cover any range or sink areas prone to splashes and spills.
  • Outlet Placement: Note any outlets on the wall and decide if they will be placed inside the backsplash or repositioned. The outlets must be safely accessible.

Having a well-thought-out design will make purchasing materials and executing the installation much simpler.

What Materials Do I Need for a Backsplash Installation?

Once you determine the backsplash specifications, compile all the necessary materials. Avoid delays in the project by ensuring you have the following items on hand before getting started:


  • Purchase enough tile to cover the backsplash area based on your measurements and layout. Account for warped, damaged, or improperly cut tiles by getting 10-15% extra.
  • For even spacing, use tile spacers the same thickness as your grout lines.
  • Have extra accent, border, or mosaic tiles needed to complete the design.

Backing Board

  • Cement backerboard provides a stable, moisture-resistant surface for backsplashes. Use 1/2″ thick boards.
  • Fiber-cement backerboard works as well. Avoid drywall, plaster, or greenboard.
  • Make sure you have enough boards to cover the planned backsplash area.

Mortar and Grout

  • Use non-sanded grout for joints 1/8″ or smaller, sanded grout for wider joints.
  • Get premixed thinset mortar suitable for the backsplash material.
  • Have grout sealer to apply after grouting for stain protection.

Adhesives and Tapes

  • Butyl tape adheres backerboard joints and waterproofs seams.
  • Fiberglass mesh tape also reinforces backerboard joints.
  • 100% silicone caulk seals gaps between the backsplash and countertops/fixtures.

Additional Supplies

  • Tile nippers and cutters for custom tile cuts
  • Levels and squares to check flatness and alignment
  • Spacers to maintain even grout line width
  • Grout float, sponge, and buckets for grouting
  • Protective gear like gloves, goggles, knee pads
  • Drop cloths to protect surrounding surfaces from mess

Having all materials ready ahead of time prevents inconvenient, time-wasting trips to the hardware store during the installation process.

What Tools Do I Need to Install a Backsplash?

Installing a backsplash requires an assortment of tools to accurately measure, cut, place, and seal the tiles. Equipping yourself with the proper tools will make tiling much simpler. The essential tools include:

Marking and Measuring

  • Tape measure
  • Pencil
  • Chalk line
  • Carpenter’s square


  • Tile cutter
  • Tile nippers
  • Tile file

Setting and Grouting

  • Notched trowel for spreading mortar
  • Grout float
  • Grout sponge
  • Mixing buckets

Safety Gear

  • Work gloves
  • Knee pads
  • Safety goggles and mask

Having the right tools eliminates guesswork and frustration on the job. Investing in quality tools also yields better results. Sharper nippers, for example, make cleaner edge cuts in tile. Before beginning, inspect tools to ensure they are in good, working condition.

Steps for Installing a Backsplash

With your materials purchased and tools on hand, you can move on to the installation process. Follow these steps to properly install a backsplash in your kitchen:

Step 1: Prepare the Work Area

First, set up a safe, organized workspace:

  • Clear countertops and remove items on walls.
  • Cover surfaces with drop cloths.
  • Have all tools and materials nearby.
  • Make sure there is adequate lighting.

Preparing the area prevents accidents and keeps necessary items within reach.

Step 2: Install the Backerboard

Backerboard provides a stable, water-resistant foundation for the backsplash. To install:

  • Measure and cut boards to fit the space.
  • Spread thinset mortar on the wall and back of boards.
  • Press boards against the wall in the thinset.
  • Fasten with backerboard screws every 8 inches.
  • Tape seams with fiberglass mesh tape and mortar.

The backerboard must be flat and securely fastened for proper tile adhesion.

Step 3: Mark the Tile Layout

Once the backerboard is up, map out the backsplash design:

  • Based on your plan, determine the tile layout pattern.
  • Mark center lines and level base row on the board.
  • Dry lay tiles to test the pattern and fit.
  • Adjust layout as needed before final placement.

Carefully marking the design ensures straight, even tile rows.

Step 4: Spread the Mortar

To adhere tiles:

  • Apply a thinset mortar layer on sections of the backerboard.
  • Use a notched trowel to evenly spread mortar.
  • Only cover areas where you can immediately place tiles.

Mortar should be tacky but not dried out when setting tiles.

Step 5: Set and Place Tiles

Work in sections to neatly position and press tiles into the mortar:

  • Starting at the base row, place border and filler tiles as marked.
  • Use spacers between tiles to create uniform grout lines.
  • Firmly press tiles into the mortar for optimal adhesion.
  • Check lines remain straight and level as you go.
  • Allow mortar to cure per manufacturer instructions.

Setting tiles properly prevents slipping and uneven spacing issues down the line.

Step 6: Cut and Fit Remaining Tiles

  • Measure and mark tiles needing custom cuts.
  • Carefully score and snap tiles using tile cutters and nippers.
  • Smooth rough edges with a tile file.
  • Set cut pieces using mortar and spacers, just like full tiles.

Making precise tile cuts results in a seamless backsplash design.

Step 7: Apply the Grout

Grout fills in the joints between tiles:

  • Mix grout per package instructions to a thick, creamy consistency.
  • Use a grout float to spread grout over the tiles, pressing into joints.
  • Wipe away excess grout with a damp sponge.
  • Cure grout for 72 hours and apply sealer.

Letting grout fully cure prevents cracking, crumbling, and discoloration.

Step 8: Finish the Installation

Complete the project with the following finishing touches:

  • Caulk the seam between the backsplash and countertop.
  • Reinstall outlet covers and fixtures mounted over the backsplash.
  • Seal grout and wipe the area thoroughly once more.
  • Allow curing for the time recommended by product manufacturers.

Proper cleanup and curing lead to years of backsplash beauty and enjoyment.

Tips for a Successful Installation

Keep these additional tips in mind throughout the installation process:

  • Carefully read all product instructions before starting.
  • Work slowly and methodically for best results.
  • Be extremely cautious when using tools and handling adhesives/sealants.
  • Keep a wet rag nearby to quickly wipe up mortar messes and spills.
  • Always mix mortar, thinset, and grout per package directions.
  • Allow adequate drying time between steps. Rushing leads to issues.
  • Work in small sections to avoid tile displacement or adhesive drying out.
  • Keep the work area well-ventilated as adhesives and sealants can be strong smelling.
  • Dispose of excess mortar, grout, and tile pieces properly when finished.

Taking your time and exercising patience makes for the most professional looking finished backsplash.

Common Backsplash Install Mistakes to Avoid

While the installation process may seem straightforward, beginners can make missteps that ruin the final look and durability of the backsplash. Being aware of common pitfalls can help you avoid them on your project:

  • Not Planning Ahead – Skipping necessary layout planning and material gathering steps can waste time and money. Know your tile design and have all required supplies before installation day.
  • Dirty Walls and Tiles – Adhesive will fail if the backerboard and tile surfaces are not cleaned before applying. Remove all debris, grease, and dust first.
  • Applying Mortar Incorrectly – Mortar applied too thickly and not pressed firmly against the backerboard leads to poor adhesion. Read manufacturers recommended thickness and techniques.
  • Neglecting Expansion Gaps – Tiles should not be flush against countertops, cabinets, and walls. Leaving 1/8 inch expansion gaps prevents buckling or cracking.
  • Incorrect Grout – Using unsanded grout for wide joints or sanded grout for narrow joints can lead to cracking as the grout dries. Always match grout type to grout line width.
  • Not Sealing Grout – Sealing is essential for grout stain resistance and longevity. Don’t skip this step.
  • Improper Tile Cuts – Ragged, uneven tile cuts look unprofessional and can allow moisture seepage behind the tile. Master proper scoring and snapping techniques to achieve clean edges.

Being mindful of how such mistakes occur will make you better equipped to avoid them during your own backsplash installation.

Frequently Asked Questions About Backsplash Installs

Many first-time installers have lingering questions when prepping for and completing their backsplash project. Here are answers to some of the most common inquiries:

Do I Need to Hire a Professional to Install a Backsplash?

Installing a basic backsplash is very doable as a DIY project for many homeowners. Following the proper steps and using the right tools really determine success more than skill level. However, very intricate designs or natural stone may benefit from a pro.

What is the Best Grout Color for Kitchen Backsplashes?

Lighter grout colors like white or cream work well for most backsplashes as dark grout can make the space feel smaller. However, choose a grout hue that complements the tile color. Contrasting or matching shades are both options.

How Do I Cut Holes in Tile Backsplash for Outlets?

Use an angle grinder or rotary tool with a ceramic tile blade to cut outlet openings. Make small holes along the outline first rather than one long cut. Finish by tapping out the center piece with a hammer. Insert a tile nibbling bit to smooth and shape the opening.

Can I Install a Backsplash Directly Over Drywall?

Drywall alone does not provide a suitable substrate for backsplashes. Cement or fiber-cement backerboards must be installed over the drywall first to create a water-resistant surface that holds tile adhesives and mortars properly.

Is a Backsplash Necessary in the Kitchen?

While not mandatory, backsplashes serve critical functional and aesthetic purposes. Not only do they protect walls from spills and stains, but they allow you to infuse your own style. Durable, wipeable backsplashes maintain wall integrity and give kitchens decorative flair.
