What You Need to Install Backsplash


Installing a backsplash in your kitchen can completely transform the look and feel of the space. A stylish backsplash serves both form and function – protecting your walls from spills and splashes while also adding visual interest. There are several steps involved in installing a backsplash yourself, and having the right materials and tools on hand will ensure the job goes smoothly. Here is a comprehensive guide on everything you need to know to install backsplash in your kitchen.

Planning Your Backsplash Design

Before starting the installation process, you’ll want to settle on a backsplash design. Consider the following:


Ceramic, metal, glass, and stone tiles are popular backsplash materials, each with their own aesthetic. Make sure to choose a material that aligns with your kitchen’s overall style.


The backsplash is a great place to incorporate color, texture, and patterns. Browse backsplash ideas online or in home improvement stores to find a look you love.

Accent Areas

In addition to the wall area directly behind the countertop, you may want to accent other areas like the range hood or sections surrounding windows.

Backsplash Height

Standard backsplash height is 4 inches from the counter, but you can customize this – higher splashes protect more of the wall.


Map out the tile layout ahead of time, factoring in grout lines and cuts, to ensure you have enough material. Avoid using small tile pieces.

Gather Supplies

Before installing backsplash, ensure you have all necessary supplies on hand:

  • Backsplash tiles
  • Thinset mortar adhesive
  • Grout
  • Trowel for spreading thinset
  • Grout float for applying grout
  • Spacers for consistent grout lines
  • Tile cutter (if cutting tiles)
  • Wet saw (for stone tiles)
  • Grout sealer
  • Caulk/silicone sealant

Tools: tape measure, level, carpenter’s square, bucket for mixing thinset, grout sponge, towels, utility knife, drill.

Safety: glasses, gloves, knee pads, dust mask.

Having materials and tools ready beforehand makes the installation process go faster.

Preparing the Surface

Proper prep work ensures your backsplash tiles adhere properly to the wall.

  • Remove existing backsplash if there is one. Scrape off any remaining adhesive.
  • Thoroughly clean the wall area. Remove any grease or soap residue.
  • Make sure the surface is smooth. Sand down any bumps or imperfections. Fill any holes with spackle.
  • Paint the wall area with primer to improve adhesion. Let primer dry completely.
  • Mark the tile layout on the wall with a pencil so you have guidelines to follow.

Take time to correctly prep the surface for a successful finished backsplash.

Applying Thinset Mortar

With the wall prepped, you can begin applying the thinset mortar that adheres the tiles.

  • Mix the thinset to a fairly firm consistency according to package directions. Let it slake for 10 minutes.
  • Use the trowel to spread a layer of thinset on the wall area where the first tiles will go. Apply in sections you can tile before the thinset dries.
  • Use the notched edge of the trowel to create ridges for the tile to adhere to.
  • Don’t spread more thinset than you can tile over in 30 minutes. It will dry and won’t hold tiles.
  • Press tiles firmly into the thinset with a slight twisting motion. Use spacers between tiles.
  • Check tiles are level and aligned. Adjust as needed before the thinset dries.
  • Allow thinset to dry for at least 24-48 hours before grouting.

Applying the thinset properly is key for strong tile adhesion.

Grouting the Backsplash

Once thinset has dried, it’s time to apply grout between the tiles:

  • Mix grout according to package directions. Apply to the tiles, forcing it into joints with a rubber grout float.
  • Let grout harden slightly and then clean excess from the tile surface with a damp sponge. Rinse sponge frequently.
  • Polish tiles with a towel to remove any remaining haze once grout has dried to a firm consistency.
  • Allow grout to cure fully (24-48 hours) before exposing to moisture.
  • Apply sealer to grout lines to protect from stains.

Letting grout cure completely prevents discoloration or cracks.

Finishing Touches

Add the final touches to complete your newly tiled backsplash:

  • Run a bead of silicone caulk along countertop/backsplash joint. Wipe away any excess for clean finish.
  • Caulk the seam between the backsplash and wall if there is a gap.
  • Reinstall any fixtures like the range hood, shelves, or light rails that you removed.
  • Grout may shrink slightly as it cures. Check joints after a few days and regrout any gaps.
  • Seal grout annually to protect from stains and mold growth.

Taking time with final details gives your backsplash a polished finished look.

Tips for Installation Success

Follow these tips for a seamless backsplash installation:

  • Review tile packaging for any special installation instructions.
  • Carefully plan tile layout to minimize cuts and waste.
  • Always mix thinset and grout according to manufacturer’s directions.
  • Work in small sections that you can tile before thinset dries.
  • Ensure tiles are fully embedded in the thinset.
  • Clean excess grout off tiles with a damp sponge before it dries completely.
  • Allow ample drying time for thinset and grout to prevent cracks.
  • Seal grout to protect it from stains and moisture.
  • Be patient – properly installing backsplash takes time and precision.

With the right prep and materials, you can achieve a stunning, professional-looking backsplash.
