How to Apply Backsplash Kitchen

Installing a kitchen backsplash can transform the look and feel of your kitchen by adding visual interest, easy-clean surfaces, and protection behind appliances and the sink. With some planning and the right materials, applying a backsplash is a manageable weekend project for DIYers. Here is a step-by-step guide to applying a kitchen backsplash successfully.

Choose the Right Backsplash Materials

When selecting a backsplash, consider your design style, budget, and how much maintenance you want to do. Some top options include:


Ceramic, porcelain, or natural stone tile allows endless design flexibility with colors, textures, shapes, and patterns. Tile is durable, easy to clean, and resistant to moisture and heat. Purchase extra tiles to allow for cuts and breakage.


Metal backsplashes like stainless steel, copper, or aluminum provide a modern, industrial look. Metals are sleek, durable, and low maintenance. Use caution when handling and cutting metal.


Glass tile or glass sheet backsplashes create shiny, elegant designs. Glass is heat and water-resistant but can chip or scratch. Use specialized cutters and adhesives.

Stone Slab

Granite, marble, slate, or soapstone slabs offer natural beauty. Stone is durable but heavy, so structural reinforcement may be needed. Use a wet saw to cut stone.


Wood adds warmth and texture. Use moisture-resistant boards or plywood for kitchens. Unfinished wood can be stained or painted. Wood requires sealing and careful cleaning.

Prepare the Surface

Proper surface prep ensures your backsplash adheres securely and looks its best:

  • Remove existing backsplash if present. Scrape off old adhesive or grout.
  • Thoroughly clean the wall area with a degreaser to remove dirt, grease, and soap scum.
  • Sand glossy surfaces to help the adhesive stick. Wipe away dust.
  • Fill any holes or imperfections with spackle and sand smooth when dry.
  • Prime painted walls before applying the backsplash.

Plan the Layout

Decide on your backsplash design and map it out:

  • Measure the space and sketch your layout. Mark the outlet and switch locations.
  • Determine the tile arrangement, pattern, and color scheme. Mix tile sizes for interest.
  • Choose accent tiles and borders to finish edges and transitions neatly.
  • Buy 10-15% extra tile to allow for cuts, errors, and future repairs.

Cut the Tiles

  • For most materials, use a wet saw fitted with the proper blade for smooth cuts.
  • Cut glass and metal tiles with specialized snapping tools or a rotary tool with a diamond blade.
  • Always wear safety goggles, gloves, and a dust mask when cutting tile.
  • Follow the layout plan and cut tiles to fit around outlets, corners, and edges.
  • Cut tiles 1/8-inch smaller than the space they fit into.

Apply the Adhesive

  • Follow adhesive instructions for prep, spread rate, and set times.
  • Use a notched trowel to spread a thin, even layer of adhesive on the wall area.
  • Apply small sections at a time so the adhesive doesn’t dry before setting tiles.
  • With mosaics, apply adhesive to the mesh backing instead of the wall.
  • Don’t allow adhesive to squeeze up between tiles. Remove any excess.

Set and Grout the Tiles

  • Working in sections, press tiles firmly into the adhesive and align according to your layout.
  • Use tile spacers between pieces to maintain even grout lines.
  • Allow adhesive to cure fully before grouting, usually 24 hours.
  • Mix and apply grout with a rubber grout float, forcing it into joints.
  • Wipe away excess grout with a damp sponge and buff surface haze once dry.
  • Apply grout sealant to protect porous grout from stains.

Finish and Seal

Adding final touches ensures your backsplash stays beautiful:

  • If needed, drill holes for fixtures like soap dispensers after the backsplash is up.
  • Seal natural stone, grout, and porous tiles with an appropriate sealer.
  • Use caulk in the small gaps at edges and corners for a tidy finish.
  • Clean the backsplash initially and regularly using the manufacturers’ suggested products.

With good planning and care, your dream backsplash can add personality and high style to your kitchen for years to come. Don’t be afraid to get creative and make it your own! Let your backsplash reflect your tastes and home personality.

Frequently Asked Questions About Applying a Backsplash

What tools do I need to install a backsplash?

At minimum, you’ll need safety gear, measuring tape, materials for surface prep, adhesive, grout, grout float, sponges, caulk, and clamps. For cutting, you’ll need either a wet saw or snapping tools, depending on material. Have extra buckets, rags, and cleaning supplies on hand too.

What’s the best way to cut holes for outlets and switches?

Carefully measure and mark the opening needed around boxes before setting any tiles. Use a rotary tool or jigsaw to cut tile holes. For big cut-outs, make smaller slices first rather than one large hole. Wrap electrical boxes with painter’s tape to avoid scratches during cutting.

How do I create an accent strip or border?

Measure and cut border tiles at the correct width to frame the main backsplash design. Mosaic sheets can create quick border strips too. Apply borders first before filling in the middle with field tiles. Use small spacers to maintain even grout lines between border and field tiles.

Can I apply a backsplash directly over wallpaper or paneling?

It’s best to remove wallpaper, wood paneling, or other coverings first and prepare the actual wall underneath. Coverings can interfere with proper adhesive bonding. Removing them also allows you to inspect and repair the wall itself.

What’s the trick to getting clean grout lines?

Letting adhesive cure fully before grouting prevents hazing and discoloration. Mix grout thoroughly and apply it carefully with a grout float, pressing it deeply into joints. Immediately wipe away excess grout and residues with a lightly dampened sponge in diagonal motions. Buff again once dry.

How do I keep my backsplash looking new?

Seal tiles, grout, and natural stone to protect from stains and moisture damage. Routinely clean the backsplash by wiping with a soft cloth and recommended cleaners, avoiding harsh chemicals. Re-apply sealants and caulk as needed over time. Handle tiles gently to prevent chips and cracks.


Installing a kitchen backsplash brings visual appeal, high functionality, and an element of your personal style into the heart of your home. With smart planning and materials, the project can reasonably be DIYed in a weekend. Focus on preparing your work surface, mapping the layout, safely cutting quality materials, applying adhesive and grout mindfully, and properly caring for the finished backsplash. Get creative with textures, patterns, colors and let your backsplash reflect your unique taste and personality. With the right process, your backsplash can be a focal point you enjoy for many years.
