How to Install Tile Backsplash in Kitchen

Installing a tile backsplash in your kitchen is an easy way to add visual interest, color, and texture while protecting your walls from splatters and stains. With some planning, the right materials, and a weekend to spare, you can transform your kitchen with a beautiful backsplash.

Getting Started

Before you begin tiling, you’ll want to make sure you have all the necessary supplies and tools on hand. Here’s an overview of what you’ll need:


  • Tile – ceramics like porcelain, glass, and natural stone are popular options
  • Mortar or thinset adhesive
  • Grout
  • Caulk
  • Spacers
  • Sealer (for porous tiles like natural stone)


  • Tape measure
  • Pencil
  • Level
  • Tile cutter
  • Rubber grout float
  • Sponges
  • Buckets
  • Mixing paddle

Preparing the Wall

Proper prep work ensures your tiles adhere properly and last a long time.

  • Clean the wall thoroughly, removing any oil, dust or existing paint.
  • Make any necessary repairs to the drywall, evening out the surface.
  • Apply painter’s tape along the edges and around the outlets to protect them from the thinset mortar.
  • Mark the center point and make horizontal and vertical reference lines to guide the first row.

Applying the Tile Mortar

Mix the thinset mortar according to package directions and apply it evenly to a small section of the wall area with the notched edge of the trowel. Apply only as much as you can tile in about 20 minutes before it skins over.

  • Use a 3/8” V-notched trowel for standard wall tile.
  • Use a 1/4” square-notched trowel for mosaic sheets, small tiles, and smooth, flat backsplashes.
  • Hold the trowel at a 45° angle to get even coverage.
  • Apply additional mortar with the flat edge of the trowel to the tile backs for maximum adhesion.

Setting the Tiles

Once your mortar is ready, it’s time to start setting your tiles.

  • Begin in the center, using spacers to leave even 1/8” grout lines.
  • Make sure tiles are aligned with the reference lines and pressed firmly into place.
  • Work in sections so the mortar doesn’t dry before tiles are applied.
  • Don’t spread the mortar too far beyond where you’re currently working.

Cutting Tiles

Use a wet saw or manual tile cutter to cut any tiles needed to fit around outlets, corners, or edges.

  • Make precise measurements and go slowly for clean cuts.
  • Use eye and ear protection when cutting.
  • Keep a bucket of water nearby to keep the blade wet when cutting.


Once all whole tiles are placed, you can fill the grout lines for a finished look.

  • Allow the mortar to cure fully before grouting, usually about 24 hours.
  • Apply grout with a rubber grout float, pressing it deeply into the joints.
  • Wipe away excess grout with a damp sponge.
  • Avoid wiping too much as the grout will shrink and crack as it dries.
  • Apply a sealer if necessary per product instructions.

Finishing Touches

The final details complete your new backsplash.

  • Remove the painter’s tape after grouting once mortar is cured.
  • Caulk along the countertop and edges with a flexible silicone caulk.
  • Clean any remaining grout haze with a barely-damp sponge once fully cured.
  • Seal grout and porous natural stone tiles.
  • Stand back and admire your stunning new backsplash!

Frequently Asked Questions

What type of tile is best for backsplashes?

Ceramic, porcelain, glass, and natural stone tiles all work beautifully. Choose what fits your design vision and budget. Porcelain is very durable. Natural materials like marble add classic elegance. Mosaics make a bold statement.

How difficult is tiling a backsplash?

With proper preparation and by following the process step-by-step, installing a backsplash tile is totally DIY-friendly. Go slowly, watching online tutorials as needed. Focus on getting the wall prep and tile layout right.

Should backsplash tile go all the way to the ceiling?

Not necessarily. Standard backsplash height is 4” above countertops. Going all the way up creates a bold look. Partial heights are common, letting your wall color show. Do what works best for your kitchen.

How do I cut holes in tile for outlets?

Use a rotary tool or small circular saw to cut outlet openings before setting those tiles. Make cuts just inside the cover plate screw holes. Alternatively, tiles around outlets can be cut in place with a carbide hole saw.

Can I use different grout colors?

Absolutely. Contrasting grout lines can add interest and dimension. White grout keeps things clean and bright. Dark grout defines lighter tiles. Matching grout minimizes visibility of lines. Choose the look you like.

How long does it take for grout to dry?

Grout dries to the touch in 3-4 hours but continues curing for 72 hours. Avoid getting it wet during that time. Using a grout sealer helps protect it as it cures. Don’t polish off all remaining haze too soon.


Installing a tile backsplash is an achievable DIY project that can completely transform the look of your kitchen. With the right planning, materials, tools, and patience, you can create an eye-catching focal point full of personality. Pay close attention to preparing the wall surface, setting tiles in the mortar, and proper grouting technique to ensure your new backsplash looks amazing and provides lasting function.
