How to Install Backsplash Sheets of Tile

Backsplashes provide an easy way to add visual interest and protective covering behind sinks, stoves, and countertops. Installing tile backsplash sheets can upgrade the look of any kitchen or bathroom. With some basic tools and materials, you can achieve a professionally-finished backsplash on your own. This comprehensive guide will walk you through all the steps for a successful DIY tile backsplash installation.

Choose the Right Tile Backsplash Materials

Selecting the right tiles and materials will ensure your project gets off to a good start. Consider the following when planning your backsplash tile sheets:

Tile Material

  • Ceramic – Classic option available in endless colors/finishes from matte to glossy. Durable and water-resistant.
  • Porcelain – Similar to ceramic but denser and even more impervious to moisture. Withstands heat better.
  • Glass – Sophisticated, shiny option. Usually small mosaic tiles or mixed with other materials. Not as durable.
  • Metal – Bold look for contemporary spaces. Stainless steel, copper, brass bring unique textures.
  • Natural Stone – Elegant and earthy. Marble, travertine, slate bring natural variation. Requires sealing.

Tile Size

  • Mosaics – Tiny 1-inch tiles create intricate patterns. Mesh backing makes installation easier.
  • Subway – Rectangular 2-by-4-inch size created classic bricklay look. Timeless and versatile.
  • Large Format – 6-inch or 12-inch square tiles create modern, seamless look.

Tile Sheets

  • Mesh-backed tiles – Tiles adhered to mesh sheets for easier handling. Available in mosaics, subways, and more.
  • Tile strips – Long, narrow rows of tile adhered to strips of backing. Simple way to get subway tile look.


  • Cement-based – Most common and economical option. Available in multiple colors.
  • Epoxy – Extremely durable and waterproof. Resists stains and scratches. Limited color options.
  • Silicone – Flexible; used for areas needing water resistance like showers.


  • Thin-set mortar – Modified dry cement backerboard and tiles to substrate. Available in different formulas.
  • Mastics – Pre-mixed pastes to adhere tile. Not as strong as thin-set; best for walls.
  • Adhesive mats – Mesh sheets go on wall; tiles adhered directly. Easiest installation.

Prep the Installation Surface

Take time to properly prepare the installation surface for best results.

Clean and Dry the Surface

Ensure the wall is clean and dry before applying any tile. Use TSP cleaner and rinse thoroughly to remove grease, soap residue, or any coatings. Allow to dry completely.

Remove Outlets and Fixtures

Take out existing outlets, switch plates, light fixtures, or plumbing fixtures that are in the backsplash area. You will re-install them later.

Sand Glossy Surfaces

If painting on a glossy surface like vinyl or laminate, scuff sand with 100 grit sandpaper so the mortar can adhere. Wipe away dust.

Fill Any Holes or Cracks

Fix any holes or cracks in the wall surface with spackle or caulk to create an even surface. Let dry completely.

Paint Dark Surfaces

If existing wall is a dark color, apply a coat of white primer. This will help the grout stand out later.

Apply Cement Board

Cut and mount cement backerboard if applying tile above countertops. This provides a rigid, stable substrate.

Plan Your Tile Layout

Take measurements and map out your tile plan for best results.

Measure the Space

Measure the height and length of the backsplash area. Repeat for any sections broken up cabinets, windows, etc.

Purchase 10-15% Extra Tile

When purchasing tile, get 10-15% more than your measurements to account for broken tiles and pattern matching.

Map Your Tile Layout

Draw the backsplash area to scale and experiment with tile arrangements. Avoid narrow cuts.

Choose a Pattern

Decide on the look you want. Options include horizontal rows, vertical stacks, brick layout, or unique designs.

Account for Outlets

Adjust your plan to incorporate any outlets, switches or fixtures. They should align with grout lines.

Allow Room for Grout Lines

Spacing between tiles must be accounted for. Plan for 1/8-inch grout lines with most tile sizes.

Install the Tile Backsplash

Once you have prepped the area and planned the layout, you are ready to install the tile sheets. Follow these steps:

Mix Thin-Set Mortar

In a bucket, combine thin-set powder with latex additive and water per package directions. Mix to a smooth consistency.

Apply Mortar to the Wall

Use a notched trowel held at a 45° angle to spread a thin layer of mortar onto the wall area.

Press Tiles into Mortar

Cut mesh backing from first sheet. Press tiles firmly into mortar, using spacers for even alignment.

Continue Setting Tiles

Work in sections applying mortar and setting tiles row by row or section by section. Remove any excess mortar squeezed between tiles.

Cut Edge and Filler Tiles

Measure and cut partial tiles as needed to fill edges and gaps using a wet saw or tile cutter.

Let Tiles Set

Allow tiles to set in mortar according to manufacturer’s directions, usually 24 hours. Remove any spacer tabs.

Grouting the Backsplash

Once the thin-set mortar has cured, it’s time to grout the tiles. Follow these steps:

Mix the Grout

In a bucket, mix grout powder with water to a thick peanut butter-like consistency. Let stand 5 minutes.

Spread Grout Across Tiles

Use a rubber grout float or squeegee to spread grout in angled, circular strokes, pressing into joints.

Wipe Away Excess Grout

Let grout sit briefly till slightly firm. Use a damp sponge to wipe diagonally and remove excess grout from tile surface.

Apply Final Cleaning

Once grout has dried 10-15 minutes, use a soft cloth to polish and remove any remaining haze or film.

Allow to Fully Cure

Let grout cure fully according to manufacturer’s directions, usually 24-72 hours for foot traffic.

Finish the Installation

Apply the finishing touches to complete your newly tiled backsplash.

Re-install Fixtures

Put back any fixtures like electrical plates, sconces, or soap dispensers removed earlier.

Apply Grout Sealer

Use grout sealer to protect cement-based grout from stains. Allow to dry per product directions.

Caulk Edges

Apply a thin bead of flexible caulk around top edges, corners, and any gaps. Smooth with fingertip.

Wipe Clean

Use a soft, damp microfiber cloth to gently wipe down the entire tiled area. Buff dry with a towel.

Stand Back and Enjoy!

Once everything is dry, stand back and admire your stunning, newly tiled backsplash!

Frequently Asked Questions About Installing Tile Backsplash Sheets

Still have some questions about installing a tile backsplash? Here are answers to some frequently asked questions:

What tools do I need to install a tile backsplash?

You will need basic tools like a tape measure, pencil, level, tile cutter, mixing bucket, notched trowel, grout float, sponges, rags, and clamps. A wet saw is also useful for intricate cuts.

Do I need to seal my tile backsplash?

Ceramic and porcelain tile do not require sealing as they are impervious to moisture. Natural stone tiles should be sealed to prevent staining and damage.

How do I cut the tile backsplash around outlets?

Carefully measure and mark tiles to be cut around outlets. Use a utility knife to score and snap tiles. Or use a wet saw for clean edge cuts.

Should I use cement backerboard for a tile backsplash?

Cement backerboard provides a rigid, stable surface for tile adhesion. It’s recommended for installations over drywall or above countertops.

How long does tile thin-set mortar take to cure?

Thin-set mortar usually fully cures in 24-48 hours. Review manufacturer’s directions for recommended cure times before grouting or using the area.

Why is my tile backsplash grout cracking?

If grout cracks it is likely due to inadequate thin-set mortar curing time. Also allow grout to cure fully (24-72 hrs) before exposure to moisture.

Can I apply tile over existing backsplash?

It is not recommended to tile over existing backsplash. Remove old backsplash completely before attempting new tile installation.

How do I clean and care for my tile backsplash?

Use mild soap and water to regularly clean tile. Re-seal natural stone annually. Avoid abrasive cleaners which can damage grout or scratch tiles.
