When Tiling Backsplash Where Do You Start

Installing a tile backsplash in your kitchen can dramatically transform the look and feel of the space. However, knowing where to start when tiling a backsplash can feel daunting for any DIYer. Proper planning and preparation are key to achieving the stylish backsplash you envision. Here is an overview of the step-by-step process for tiling a kitchen backsplash from start to finish.

Selecting the Tile

The tile itself will set the tone for your whole backsplash design, so this is the ideal starting point. There are countless backsplash tile options available today in a range of styles, materials, colors, shapes and sizes. Consider the following when choosing tile for your backsplash:

  • Style – Select a tile that fits the aesthetic you want, whether modern, farmhouse, traditional or something else entirely.
  • Materials – Ceramic, porcelain, glass, metal and stone tiles are all options. Consider durability, ease of cleaning and overall look.
  • Color – Choose a neutral tile color for a clean, classic look or go bold with vibrant hues. Tie in accent colors from the rest of the kitchen.
  • Shape – Squares, subway tiles, hexagons, penny tile and more. Shape can make just as much of an impact as color.
  • Size – Larger tiles tend to have more visual impact, while smaller mosaic tiles create a busier look. Scale tiles to the size of your kitchen.
  • Texture and finish – Matte, glossy, textured and smoothed finishes all give different aesthetics.

Take time to view tile samples in person before purchasing, so you can get a feel for true color and texture. Order 10-15% extra tile to allow for cuts and pattern matching.

Preparing the Surface

Prepping the backsplash area is a crucial step for a successful end result. Here’s how to prepare the surface:

  • Clean thoroughly – Use a degreaser to remove any dirt, oil or grime on the existing wall surface where the backsplash will be installed. Rinse and let dry fully.
  • Remove existing materials – Take down any old backsplash gently, taking care not to damage the wall behind it. Scrape off all old tile adhesive.
  • Fill any holes or imperfections – Use caulk or drywall joint compound to fill cracks, dents, nail holes or any uneven spots so the surface is smooth. Let dry completely.
  • Prime the walls – After repairs, apply a coat of primer to the entire backsplash surface area. This creates a uniform base for the tile adhesive.

Taking time to properly prep the backsplash area will give your tile application the best chance for lasting success. Don’t skip this important first step!

Plan the Layout

Now it’s time to visualize how your tiles will be laid out on the backsplash surface. Planning a layout involves several considerations:

  • Tile orientation – Lay tiles vertically, horizontally or in a pattern. Vertical installation tends to make walls look taller.
  • Balance and symmetry – Strive for even coverage and a balanced look, avoiding narrow slivers of tile.
  • Accent tiles – Use special tiles at focal points or as borders. Plan where embellished tiles make the most impact.
  • Outlets and switches – Adjust the tile layout to accommodate outlets, switches and fixtures.
  • Transition to countertops – Determine how tiles will transition to, align with or overlap counter edges.
  • Grout lines – Allow for even grout lines in the spacing of the tile arrangement.

Make a diagram of the backsplash space indicating measurements and tile placement. This will serve as your guide during installation. Having a tile layout planned is the only way to know exactly how much tile is needed.

Gather Materials and Tools

Installation will go smoother if you have all necessary materials and tools prepared ahead of time:


  • Tiles
  • Tile adhesive (thinset mortar)
  • Grout
  • Grout sealant
  • Caulk
  • Tile spacers
  • Backerboard (if needed)


  • Tape measure
  • Pencil
  • Level
  • Tile cutter
  • Mixing bucket
  • Notched trowel
  • Grout float
  • Sponges
  • Tile nippers
  • Safety gear – gloves, goggles, mask

Having everything easily accessible will streamline the tiling process.

Prep and Apply Backerboard

If tiling onto drywall rather than existing tile, concrete or another solid surface, installing backerboard is advised to provide a more durable base:

  • Cut cement backerboard panels to size using a utility knife. They should fit snugly on the backsplash walls.
  • Attach the backerboard panels with backerboard screws driven into the wall studs. Place screws at least 1 inch from seams and edges.
  • Cover seams between panels with backerboard tape. Apply a thin layer of thinset mortar over the tape with a trowel.
  • Let the backerboard installation fully cure for 24-48 hours before tiling.

Backerboard gives a water-resistant base that prevents moisture damage behind the tile.

Apply the Adhesive Thinset Mortar

Applying the tile adhesive properly is one of the most vital steps. Follow these best practices:

  • Use a notched trowel to spread thinset adhesive on the backsplash surface, holding at a 45-degree angle.
  • Apply only as much adhesive as can be tiled over before skinning occurs, typically in 2-4 foot sections.
  • Use the trowel notch size recommended for the tile – larger tiles require deeper notches.
  • Press tiles into place with a back-and-forth motion, then rotate slightly. This ensures maximum adhesive contact.
  • Check for full adhesive coverage by lifting a tile periodically – at least 95% should make contact.

Take care to spread adhesive evenly for a seamless, durable tile application. Allow to dry fully before grouting.

Cut and Apply Trim Tiles

Few backsplashes use only full tiles. Prepare to cut tiles to size for these applications:

  • Perimeter edges where tiles meet cabinets or walls. Measure and cut border tiles for precise fit.
  • Around outlets, switches, windows and other obstructions. Measure and cut tile openings as needed.
  • Accent tiles, mosaics strips and other special pieces. Measure and cut to incorporate them.

Make straight cuts using a manual tile cutter and curved or notched cuts with tile nippers. Save all tile scraps – they may come in handy!

Apply cut tiles carefully using the same methods as full tiles. Blend them into the pattern seamlessly.

Install the Tiles

Now comes the fun and satisfying part – installing the field tiles throughout the main backsplash area:

  • Follow your pre-planned tile layout, installing one section at a time. Use spacers between tiles for even grout line spacing.
  • Work in small sections so adhesive does not dry before tiles are applied. Check thinset for tackiness regularly.
  • Push tiles firmly into adhesive using a back-and-forth motion to collapse the ridges and achieve maximum contact.
  • If the tile pattern has a focal point, work outward from that section so spacing stays symmetrical.
  • Periodically remove a tile and check the back to ensure at least 95% adhesive transfer onto the tile.
  • Clean away excess adhesive and use shims if needed to keep tiles even as installation progresses.

Take time with the tile setting process for flawless results. Allow to fully cure for at least 24 hours before grouting.

Apply the Grout

Grout fills the joints between tiles, completes the pattern and gives a finished look:

  • Choose a grout color that complements the tile. Contrasting or matching shades are both options.
  • Apply grout by spreading it over the tile surface in a diagonal motion using a grout float or squeegee. Pack it deeply into joints.
  • Let the grout rest and firm up for 10-15 minutes before wiping away excess. Use minimum pressure.
  • Polish the tiles by wiping firmly with a clean, damp sponge in a circular motion. Rinse sponges frequently.
  • Once grout has cured, apply a grout sealant to protect from moisture and staining.

Take care applying grout and wiping away excess. Well-grouted tiles stay securely in place for the long haul.

Finishing Touches

A few final details complete your backsplash installation:

  • Soak brush heads in water and scrub spots of adhesive residue before drying. This prevents damage to tile faces.
  • Use caulk in corner joints and narrow gaps. Apply in a consistent bead, then smooth with a damp finger.
  • If edges meet countertops or other surfaces, apply caulk where they meet for a seamless transition.
  • Lastly, clean the entire surface with a tile and stone cleaner to remove remaining haze and dust.

With some finishing refinements, you can step back and admire your stunning, newly tiled backsplash!

Maintaining Your Backsplash

Put effort into caring for your backsplash so it maintains its eye-catching look:

  • Clean using a dedicated tile and stone cleaner, not harsh chemicals. Vacuum dust before wet cleaning.
  • Re-apply grout sealant once a year to protect from staining and permeability.
  • Address new cracks, chips or missing grout right away to prevent damage spreading. Regrout as needed.
  • Limit moisture reaching the backsplash area around sinks to prevent loose tiles over time.
  • Use a squeegee after showering or bathing to keep water from pooling at tile edges near bathtubs.

With proper care and maintenance, your kitchen backsplash will deliver beautiful style for years of enjoyment!

Tips for Success

Tiling your own backsplash is very achievable for a dedicated DIYer. Keep these tips in mind:

  • Gather all materials and tools ahead of time so they are on hand when needed.
  • Follow the manufacturer’s instructions for all products (mortar, grout, etc). Don’t take shortcuts.
  • Make careful measurements and use spacers to ensure straight grout lines.
  • Work methodically in small sections for best results.
  • Clean as you go – this prevents tile haze and adhesive residue from drying.
  • Ask a tile professional or hardware store for advice if you encounter any issues during the project.
  • Be patient! Allow sufficient drying time of thinset mortar and grout for a quality finished product.

With proper planning, materials, effort and time allocated, you can install an eye-catching, durable tile backsplash you’ll love admiring every time you enter your kitchen.
