Select the Right Tools

Installing tile requires some specialized tools to get professional looking results. Be sure to have the following on hand:

  • Tile cutter – Manual or electric cutter to trim tiles
  • Tile spacers – Small plastic crosses to maintain even grout lines
  • Grout float – For smoothing and finishing the grout between tiles
  • Mixing buckets & paddles – For blending mortar and grout
  • Notched trowel – Spreads mortar evenly on the wall
  • Tile nippers – To nip small pieces from cut tile edges
  • Wet saw (optional) – For intricate tile cutting

Don’t forget key safety gear like goggles, gloves, knee pads, and a dust mask. Having the right tools will make your installation much easier.

Prepare the Surface

Prepping the installation surface is crucial for a long-lasting backsplash. Follow these tips:

  • Clean thoroughly – Remove any existing wallpaper, soap residue, oils, waxes, or other debris.
  • Repair flaws – Fix any holes, cracks, uneven sections so the wall is smooth.
  • Prime – Apply primer to help the mortar adhere to the wall surface.
  • Mark the layout – Map out tile spacing on the wall with a pencil.
  • Apply adhesive backing (optional) – Self-adhesive sheets help set the tiles in place.

Taking time to properly prepare the wall will provide a solid foundation for your backsplash tiles.

Spread the Tile Mortar

Mix and apply mortar evenly on the wall surface to adhere the tiles. Follow these best practices:

  • Mix per instructions – Slowly add powdered mortar to water in a bucket using a paddle mixer.
  • Use right amount – Don’t mix up more than can be used in 30 minutes to avoid drying.
  • Work in sections�- Spread mortar over small sections at a time to prevent premature drying.
  • Apply even layer – Use a notched trowel at a 45� angle spreading mortar evenly.
  • Use proper thickness – Maintain a mortar layer between 1/8″ to 3/16″ thick.
  • Check adhesion – Make sure mortar sticks firmly and doesn’t slide off wall.
  • Let cure – Allow mortar to dry slightly until tacky before adding tiles.

Carefully applying the mortar creates a robust base for your tile installation.

Set the Tiles

Once the mortar has cured to a tacky consistency, you’re ready to set the tiles:

  • Work in small sections – Set tiles over mortar in 3-4 square foot sections.
  • Use spacers for alignment – Place tile spacers between tiles to keep grout lines even.
  • Press tiles into place – Use a slight twisting motion to adhere tiles firmly in the mortar.
  • Check for levelness – As you go, use a leveler to ensure tiles are even.
  • Cut edge tiles as needed – Use a wet saw or tile cutter for perimeter and around outlets.
  • Let mortar cure – Allow 24 hours for mortar to fully dry before grouting.

Working methodically to lay the tile will give you the best end results.

Apply the Grout

Grout fills the seams between tiles with color and waterproofs the surface. Follow best practices when grouting:

  • Mix per package directions – Slowly add powder to the amount of water specified.
  • Apply to small areas – Spread over 3-4 square feet sections using a grout float.
  • Push into crevices – Force grout firmly into tile seams and gaps.
  • Wipe away excess – Use a damp sponge in circles to remove surface grout.
  • Rinse sponge frequently – Frequent rinsing keeps grout residue from smearing.
  • Shape and smooth joints – Sculpt grout into a concave shape for best durability.
  • Let cure – Allow 72 hours for grout to fully set before sealing (if needed).

Careful grouting will give you durable, clean looking joints between tiles.

Seal and Finish

Sealing is an optional final step depending on the type of tile used:

  • Read manufacturer advice – Check if your tile needs sealing and what products to use.
  • Clean tiles thoroughly first – Remove all residues with a pH neutral cleaner.
  • Apply sealer � Use a paintbrush or sealer sponge following product instructions.
  • Buff off excess – Wipe away any sealer on the tile surface after 5-10 minutes.
  • Additional coats if needed – Very porous tile may need 2-3 sealer coats.
  • Cure time – Avoid cleaning or getting the tiles wet for the sealer cure time.

Sealing tiles adds an extra layer of protection for more stain and water resistance.

And that’s it – you now have a fully tiled backsplash ready to enjoy! With the right prep, tools, and techniques, you can achieve professional-looking results.

Frequently Asked Questions About Putting Up Backsplash Tile

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

What’s the Best Grout Color for My Backsplash Tiles?

Pick a grout color that matches or complements your tiles. For bold, colorful tile, use white or off-white grout. For neutral tiles, use a gray or beige grout. Contrasting grout can also create a statement.

How Do I Cut Holes in Backsplash Tile for Outlets?

Trace the outlet on your tile and drill a pilot hole in one corner with a ceramic drill bit. Use a jigsaw to cut out the outlet opening. Use nippers and sandpaper to refine the hole edges. Be sure to turn off power at the breaker before starting.

Should I Use Premixed or Powdered Mastic to Apply the Tile?

Powdered thinset mortar is preferred for walls as it’s thicker and provides better adhesion power. Only use premixed mastic for very small mosaic tiles or tile repairs.

What Kind of Backer Board is Best Behind a Tile Backsplash?

Cement backer board like Durock or WonderBoard provides the most stable and water-resistant backing for tile. Installed with thinset mortar, it creates an excellent adhesion surface.

How Long Does Grout Need to Dry Before Sealing a Tile Backsplash?

Grout should be allowed to cure fully for 72 hours before applying any sealer or water. This gives the grout time to dry completely and achieve maximum hardness.

Should I Use Sanded or Unsanded Grout for Wall Tiles?

For joints 1/8 inch or smaller, use unsanded grout. The fine texture fills narrow spaces best. Use sanded grout for wider grout lines. The sand allows it to dry hard.

What’s the Minimum Backsplash Height for a Kitchen?

The standard minimum backsplash height is 4 inches. However, many designs extend the backsplash to 18-24 inches high or all the way to the underside of wall cabinets for more protection.

How Do I Cut Tile Around Outlets and Switches?

Use a rotary tool or oscillating tool to cut square or L-shaped notches around the boxes so tile slides underneath. Take care not to damage the electrical components.


Installing a tile backsplash offers a gorgeous way to transform the look of your kitchen or bathroom. With proper planning and preparation, the right tools, and careful technique, you can achieve professional-looking results. Focus on establishing a clean, smooth substrate, proper mortar use, precise tile-setting, and careful grouting. Seal tiles if needed for added durability.
