How to Install Backsplash in Your Kitchen

Installing a backsplash in your kitchen can completely transform the look and feel of the space. Not only does a backsplash provide an extra layer of protection for your walls against splashes and spills, it serves as a decorative focal point that brings together your cabinetry, countertops, and other design elements. With the right materials and some DIY skills, you can install a stylish, affordable backsplash in your kitchen.

Choose Your Backsplash Materials

The most common materials used for kitchen backsplashes include:

  • Tile: Ceramic, porcelain, or natural stone tiles allow you to create a custom look. Tiles come in endless colors, shapes, sizes, and textures. They are durable, easy to clean, and relatively affordable.
  • Glass tile: Adds a shiny, sleek look. Glass tile is available in different colors and degrees of opacity. It’s more expensive than ceramic or porcelain.
  • Metal: Metal backsplashes like stainless steel, copper, or tin add a contemporary, industrial vibe. Metals are very durable but prone to scratches.
  • Stone slabs: Natural stone like marble, granite, or slate can be cut into large format slabs for a seamless look. Stone is elegant but porous and requires sealing.
  • Peel-and-stick: Vinyl tiles with adhesive backing provide an easy, affordable option. Many styles mimic real tile or stone.

Consider the overall look you want and your budget. Also factor in ease of cleaning – heavily textured materials trap grease and grime.

Prepare the Surface

Proper prep work ensures your backsplash installation stays securely bonded to the wall.

  • Remove existing backsplash if there is one. Scrape off any leftover adhesive or thinset mortar.
  • Inspect the drywall or plaster behind the backsplash area. Look for cracks, damage, or uneven spots that need patching/sanding.
  • Clean the entire surface using a degreasing cleaner or TSP substitute to eliminate dirt, grime, soap residue etc. Rinse thoroughly.
  • Let the wall dry completely before applying any new adhesive materials.
  • For glossy painted walls, sand down the surface lightly with 120-150 grit sandpaper to help the mortar adhere better. Avoid exposing the bare drywall.

Plan the Layout

  • Measure the space and make sure your material purchases allow for a small buffer. It’s better to have extras than to run short.
  • For tile, map out the tile layout on paper first. Check that cuts at the edges/corners work out evenly and minimize slivers.
  • Snap chalk lines as guides for the first row. Use a level to ensure straight, even rows.

Install the Backsplash

Follow the product instructions for your specific materials. The basic installation process is:

Step 1 – Apply Mortar

  • For tile, use a notched trowel to spread a thinset mortar evenly over the installation area. Apply only as much as you can tile over before the thinset dries.
  • For other materials like stone slabs, glass panels, or peel-and-stick tiles, apply a mortar suitable to the backing.

Step 2 – Set the Backsplash

  • Begin with the bottom row. Set tiles/panels in place, using spacers for consistent grout lines.
  • Press each piece firmly into the mortar. Use a rubber grout float or pounding block to ensure full contact.
  • Check alignments frequently using a level and measurements. Adjust as needed.
  • Allow mortar to cure fully before continuing if installing over multiple days.

Step 3 – Finish Grouting and Sealing

  • Once tiles are firmly set, remove spacers and spread grout over the joints. Allow grout to cure per product guidelines.
  • For natural stone, apply a sealant over the entire surface to protect from stains. Reapply sealer periodically.
  • Clean any excess thinset/grout with a sponge and clean water. Use a grout haze remover if needed.

Step 4 – Seal Edges and Finish

  • Caulk along the edges and seams where the backsplash meets the countertop, walls, or cabinets using a flexible silicone sealant.
  • Allow all adhesives, grouts, and sealants to fully cure before using/cleaning the backsplash.

With good prep work and by taking your time, you can achieve beautiful, professional-looking results. The finished backsplash pulls your whole kitchen together!

FAQs About Installing a Backsplash

What tools do I need to install a backsplash?

Basic tools include a tape measure, pencil, level, spatula or trowel, grout float, sponges, buckets, silicone caulk and caulk gun. You may also need a circular saw with a diamond blade for cutting tile. Always use safety gear like gloves and eye protection.

What’s the best way to cut ceramic tiles?

Mark the tile where you want to cut it, then score the line multiple times with a carbide scoring tool. Place the tile over a piece of scrap wood and press down firmly until the tile snaps cleanly along the scored line. You can also use a wet saw for quick, accurate cuts.

Should the backsplash go all the way to the ceiling?

Usually backsplashes end at 4-6 inches above the countertop. But you can install it all the way to the ceiling for a full wall effect. Just keep in mind that a full height backsplash requires more precise cutting around outlets, cabinets, etc.

How long does backsplash tile installation take?

It depends on the size of the area and your skill level. Once you have the materials and surface prepped, an experienced DIYer can often tile a standard 8-10 sq. ft. backsplash in one day. Allow additional time for novice installers.

Can I install backsplash over existing tile?

Yes, it is possible by applying a mortar layer over the old tile first to create a bonding surface. However, it’s generally better to remove old backsplash completely so you start with a smooth, even wall surface.


The key to a successful DIY backsplash project is taking the time to properly prepare your work surface. With the right materials and tools, you can change up your backsplash area to create a whole new look for your kitchen. The end result will provide the perfect finishing touch that pulls your entire kitchen décor together.
