How to Do Ceramic Tile Backsplash

Installing a ceramic tile backsplash can transform the look of your kitchen or bathroom. With the right materials and some basic DIY skills, you can create a stylish, durable backsplash yourself. Here is a step-by-step guide to teach you how to do ceramic tile backsplash.


A backsplash protects the walls from water damage and splashes in areas prone to moisture like behind a kitchen sink or bathroom vanity. Tiles are a classic, easy-to-clean choice. Ceramic tiles now come in a huge range of colors, shapes, sizes and textures to suit any design aesthetic.

Doing a tile backsplash is a relatively easy weekend project that does not require specialized skills. With some planning, patience and basic tools, you can achieve professional-looking results. The key steps include proper surface preparation, laying out the tile design, applying thinset mortar, setting the tiles, and grouting.

Preparing the Surface

Proper prep work ensures the tiles adhere tightly.

  • Clean the surface thoroughly to remove dirt, grease and soap scum.
  • Seal porous surfaces like drywall with primer.
  • Check for any imperfections in the wall and fill with spackle if needed.
  • Paint the surface if sticking to a new color.
  • Apply painter’s tape around the edges for a clean finish.

Choosing a Tile Layout

Decide on the tile layout before starting. This will determine the tools and tiles needed.

  • Subway – Brick pattern of 3×6 or 4×12 tiles
  • Stack – Vertical arrangement of rectangular tiles
  • Herringbone – Tiles set in zigzag pattern
  • Hexagons – Six-sided tiles set in rows
  • Patterns – Combining colors, shapes and textures

Mix sizing like 4×4 and 12×24 tiles for interest. Accent with trim or mosaic tiles. Sketch plans to visualize spacing and alignment.

Applying the Thinset Mortar

Thinset mortar bonds the tiles to the surface. Using a notched trowel, apply a thin layer of mortar over just a small section at a time. Spread evenly and firmly press tiles into the mortar.

  • Choose unsanded for walls or sanded for floors.
  • Apply only 1/4 to 3/8 inch thickness.
  • Work in small sections so mortar doesn’t dry out.
  • Use spacers between tiles for consistent alignments.
  • Don’t spread mortar past the tape edges.
  • Push tiles firmly into place and check levelness.

Cutting and Shaping Tiles

Use a wet saw or manual cutter for precise cuts. Make practice cuts first on spare tiles.

  • Measure and mark cuts needed for edges and around outlets.
  • Cut tiles with the good side face up.
  • For rounded edges, use tile nippers after cutting.
  • Smooth cut edges with sandpaper or stone as needed.
  • Apply mortar first, then set cut tiles in place.

Grouting the Tile

Grout fills the joints, sealing and finishing the tiled surface. Work in small areas and wipe immediately.

  • Mix grout per package directions. Consistent texture is key.
  • Apply grout over the surface using grout float.
  • Push into joints and remove excess grout immediately.
  • Wipe diagonally across tiles with damp sponge.
  • Clean grout haze once dry using soft cloth.
  • Allow to fully cure for 48-72 hours before sealing.

Sealing and Caulking

Sealer protects porous grout and tile surfaces. Caulk fills any gaps at edges.

  • Clean surface thoroughly and let dry before sealing.
  • Apply sealer according to product instructions.
  • Use silicone caulk and tool along the edges and seams for clean finish.
  • Allow caulk to fully cure for 24 hours before contact with water.

Caring for the Finished Backsplash

With proper care, your tile backsplash will stay beautiful for years.

  • Seal grout annually. Reapply sealer periodically.
  • Use pH neutral cleaner for regular maintenance.
  • Don’t allow soap or grease build up. Rinse thoroughly.
  • Avoid abrasive cleaners or scrubbing that can dull the surface.
  • Repair any cracked or damaged grout to prevent moisture issues.

Tips and Tricks

  • Stick tiles to cardboard to arrange layout before installing.
  • Use small leveling spacers for uniform tile spacing.
  • Work top to bottom and start at the center. Dry fit border tiles.
  • Clean as you go – this prevents grout haze and tools sticking.
  • Add accent tiles like subway stacked or herringbone for interest.
  • Pair with matching caulk for seamless look along countertops or tub.

Frequently Asked Questions

How much tile do I need?

Measure the area and add 10% extra to allow a margin of error. The tile square footage x number of tiles per square foot = total tiles needed.

What type of thinset should I use?

Use unsanded, latex or polymer modified thinset for walls. Sanded mortar is for floor applications. Match product to tile material.

How soon can I grout after applying tiles?

Wait 24-48 hours for the thinset mortar to fully cure before grouting. Check manufacturer directions.

What is the best grout to use?

Epoxy grout is most durable and water resistant. Standard sanded grout works for most tile projects. Match grout color to the tile.

How do I cut ceramic tiles?

Use a wet saw or tile cutter for straight cuts and tile nippers for small curved cuts. A rotary tool with diamond blade can also be used.

Can I install a tile backsplash over existing drywall or tiles?

Yes, as long as the surface is in good condition. Rough up glossy surfaces first. Clean thoroughly and use primer.


Installing a ceramic tile backsplash enhances your space with style, character and easy cleanability. With proper planning and tools, this is a very approachable DIY project for any skill level. Focus on careful prep work, precise tile setting and smooth grouting for professional-looking results you will enjoy for years to come.
