How to Do a Backsplash Yourself


Installing a backsplash in your kitchen can instantly upgrade the look and feel of the space. While many homeowners opt to hire a professional, doing a backsplash yourself is an achievable DIY project that can save you money. With proper planning, the right materials, and some tile-setting techniques, you can transform your kitchen backsplash and gain the satisfaction of completing the work yourself.

In this comprehensive guide, we will walk you through all the steps for how to do a backsplash yourself, from picking the right backsplash tile and prepping the surface to applying thinset and grouting. With our tips and advice, you can install a stylish, on-trend backsplash that looks like it was done by an expert.

Choose the Right Backsplash Tile

The tile you select will set the tone for your whole backsplash design, so take the time to consider the look you want as well as your budget. Here are some popular backsplash tile options:

  • Ceramic or porcelain: Affordable, available in endless colors/patterns. Easy for DIY.
  • Glass: Provides a shiny, sleek contemporary vibe. Can be prone to chipping.
  • Marble or granite: Elegant natural stone look. On the higher end cost-wise.
  • Metal: Makes a bold style statement. Copper and stainless steel are common choices.
  • Mosaic: Small tiles perfect for a detailed mosaic pattern. Grout carefully.

Measure the dimensions of your backsplash area to determine the amount of tile you will need. Leave an extra 10% for cuts and waste. Buy all materials together for consistency in hue and pattern.

Prep the Backsplash Area

Proper prep work ensures your tiles will stick properly and remain securely affixed. Follow these steps:

  • Remove existing backsplash if there is one and clean the surface thoroughly.
  • Inspect the wall and repair any damage, holes, cracks with spackle.
  • If the wall surface is heavily textured, you may need to smooth it out with joint compound so tiles lie flat.
  • Apply painter’s tape around the edges of the backsplash area to protect surrounding surfaces.
  • Apply tile backer board or cement board if the walls lack this already. Secure tightly.
  • Prime the surface with a bonding primer or treatment recommended for backsplashes.

Your surface should be smooth, clean, and ready for thinset application.

Apply the Thinset Mortar

Thinset mortar adheres the tiles to the wall surface. Using a notched trowel, spread it evenly over the backsplash area:

  • Choose an appropriate thinset for the tile material and wall type per manufacturer specs.
  • Hold the trowel at a 45 degree angle to get straight, consistent notched lines.
  • Apply only as much thinset as you can tile over within 30 minutes.
  • Use the flat side of the trowel to knock down high ridges for an even coverage.
  • Consult tile guides to determine the proper trowel size and depth for your tile selection.

Take care to apply thinset thoroughly across the surface to avoid future tiles cracking or popping off.

How to Set the Tiles

Set your tiles in a logical pattern or design:

  • If using multiple tile types/sizes, map out the pattern beforehand.
  • Start tiles in the center and work outward toward the edges and corners.
  • Place the first tile. Push it firmly into the thinset and move it around slightly to ensure good adhesion.
  • Use tile spacers between each tile for consistent grout line spacing.
  • Follow your layout pattern, periodically checking tiles are level and aligned.
  • Cut border and corner tiles to shape using a wet saw or tile cutter tool.
  • Let tile set 24 hours before grouting so thinset mortar can fully cure.

Taking care to lay tiles flat and keep spacings even will ensure your pattern looks fantastic.

Apply Grout Between the Tiles

Grout fills the spaces between your tiles, giving your backsplash a polished finished appearance:

  • Allow thinset to fully cure before grouting, generally around 24 hours.
  • Apply masking tape on the countertop edge to protect from stray grout.
  • Follow product instructions but typically you mix grout powder with water to a thick, pourable consistency.
  • Holding a rubber grout float at a 45° angle, work it diagonally across the tiles pressing grout into gaps.
  • Let grout set for about 20 minutes until haze forms on tiles, then spray down with water.
  • Use a damp sponge to smooth and shape grout lines and wipe any film off tile surfaces.
  • Remove tape after an hour or so and allow 24 hours for grout to fully cure.

Taking the time to grout neatly and clean off excess will give you seamless grout line spacing and a put-together backsplash look.

Seal and Finish

The final step is applying a sealant which protects the grout and creates a nice sheen on the tile:

  • After 24 hours of grout curing, apply a penetrating sealant following product instructions.
  • Liberally apply sealant across all grout lines and tile surfaces using a paintbrush or sponge.
  • Allow sealant to soak in 10 minutes, then thoroughly wipe off excess with clean rags.
  • Buff dry any remaining residue for a streak-free finish.
  • Avoid heavy use of backsplash for 24 hours to allow sealant to fully cure.

Sealing the tiles properly gives your project a completed, professional feel and prevents stains by creating a barrier repellent to moisture.

Troubleshooting Common Backsplash Issues

Even if carefully installed, backsplash projects can run into problems. Here are some potential issues and fixes:

Tiles falling off: This is likely due to inadequate thinset mortar coverage. Scrape off loose tiles and thinset and re-apply. Ensure the wall surface is appropriately prepped and primed first.

Uneven tile/Grout lines: Check for low spots on the wall that prevent tiles from lying flat. You may need to apply thicker thinset in problem areas.

Grout cracking: Joints wider than 1/8” are prone to cracking. Ensure proper tile spacing with plastic crosses. Cracked grout can be re-grouted.

Dull finish: If tiles lack luster, the protective sealer likely didn’t cure fully or wasn’t applied properly. Re-apply sealant following directions closely.

With care and patience, you can successfully install a backsplash yourself and overcome common hurdles. Take time to review processes and ask experts for guidance. The end result will be a stunning, professional-looking backsplash you completed with your own hands.

Frequently Asked Questions

What tools do I need to install a backsplash?

Common tools needed are a tape measure, level, marker, tile cutter, mixing bucket, notched trowel, grout float, sponges, painter’s tape, and safety gear like gloves and eye protection. A wet saw is also useful for cost-effectively cutting custom tile shapes.

Should I use different thinset for glass tile?

Yes, glass tile requires a white thinset mortar without any latex additives. Latex can cause discoloration issues with translucent glass tiles over time. Ensure your thinset is recommended for glass.

How long does thinset mortar take to dry?

In general, thinset adhesive should dry for 24 hours after applying tiles before grouting can begin. This ensures tiles are firmly attached and a hard mortar bed has formed to hold tiles in place. Cool humid conditions may require longer thinset curing times.

What is the easiest backsplash tile for DIY?

Rectangular ceramic, porcelain, or marble tiles with uniform sizes and smooth edges are easiest for beginner DIYers. Avoid intricate patterns, tiny mosaics, or natural stone with ragged edges which are challenging for first-time installations.

Should backsplash go all the way to ceiling?

Backsplash height is a matter of personal preference and style. Typically backsplashes extend 4-6 inches above countertops. Going all the way to the ceiling makes a bolder visual statement. Consider your cabinets, ceilings, and overall kitchen aesthetics when planning backsplash height.


Installing a kitchen backsplash yourself allows you to save on labor costs while putting your personal stamp on your home. With careful planning, the right tools and tile choices, attention to detail in applying thinset mortar, level tile-setting, proper wide grouting, and sealing, you can achieve beautiful, professional-looking results. While backsplash projects take considerable effort and time, the impact they make is significant and will add to your daily enjoyment of the kitchen for years to come.
