How to Finish a Backsplash


A backsplash is an important design element in any kitchen, serving both aesthetic and functional purposes. Choosing the right materials and finishes for your backsplash is key to achieving the look you want while protecting the wall from moisture, splashes, and stains. While tile is a popular backsplash option, there are many different ways to finish a backsplash depending on your style, budget and needs. This guide will walk you through the process of selecting, preparing, installing and sealing a kitchen backsplash. We’ll cover everything from materials like tile, metal, glass and stone to grout options, specialized tools and tips for a flawless finished product. With the right planning and techniques, you can create a stunning, long-lasting backsplash that makes your kitchen complete.

Selecting Backsplash Materials

The material you select for your backsplash will set the tone for your whole kitchen design. Consider factors like aesthetics, durability, ease of cleaning and maintenance, and budget when choosing materials.


Tile is one of the most common backsplash materials due to its versatility, durability and affordability. Ceramic and porcelain tiles come in a vast array of colors, sizes, shapes, textures and patterns. Glass tile provides brilliant shine and depth. Natural stone tile like marble, travertine and slate add organic beauty. The grout lines in tile create a grid pattern that defines the space.

Benefits: Easy to clean, moisture-resistant, affordable, available in many styles

Considerations: Grout requires sealing, tile can crack or chip if struck


Metal backsplashes like stainless steel, copper, brass and aluminum make a bold statement. Stainless steel is modern and industrial; copper and brass impart an old-world, vintage feeling; aluminum gives a contemporary look. Metal backsplashes are impervious to moisture and quite hygienic. However, they show fingerprints, grease, water spots and scratches readily and require frequent polishing.

Benefits: Durable, heat-resistant, easy to clean, hygienic

Considerations: Prone to scratches and fingerprints, can dent, loud sound when pots hit it


Glass tile and inset glass panels create a glittering, translucent backsplash. Glass is heat- and moisture-resistant, non-porous, and easy to wipe clean. Tempered glass backsplash panels can be installed without grout. For a custom look, glass tiles can be arranged in dazzling patterns. However, glass breaks easily if hit hard and requires careful cutting and drilling during installation.

Benefits: Modern appeal, simple maintenance, hygienic, stain-resistant

Considerations: Breaks easily, glass tiles require grout


Natural stones like granite, marble, travertine, limestone, and slate can be fashioned into upscale backsplash slabs or tiles. Each type of stone has its own veining, coloring and texture for one-of-a-kind beauty. However, stone is porous and requires yearly sealing to avoid staining. It can also crack or chip if heavily impacted.

Benefits: Natural material with unique patterning, durable

Considerations: Porous and stain-prone, requires yearly sealing, cracks easily

Alternative Materials

Some unique backsplash ideas include reclaimed wood planks, pennies, bottle caps, and broken china glued to mesh backing. While beautiful, most alternative materials require special installation and sealing methods to withstand moisture and splashes. Make sure to research durability and maintenance needs.

Preparing the Surface

Proper preparation is crucial for a long-lasting backsplash installation.

  • Clean thoroughly – Use TSP cleaner to remove any grease or soap scum so tiles adhere well. Rinse and let dry completely.
  • Repair wall damage – Fill any holes or cracks with spackle and sand smooth. Spot prime repaired areas with primer.
  • Remove outlets – Outlets in the backsplash area should be detached and reinstalled over tile.
  • Prime – After cleaning, apply a tile primer to the entire backsplash surface. This improves adhesion.
  • Layout design – Map out tile layout using spacers to achieve your desired pattern. Adjust to avoid narrow cut tiles.
  • Gather supplies – Based on your tile choice, purchase adhesive, grout, sealer, tile cutter, spacers and any specialty tools needed.

Proper prep prevents problems down the road with installation and durability. Don’t skip steps!

How to Install a Tile Backsplash

Tiling your backsplash takes planning, patience and care. Follow these steps for proper installation:

Step 1: Apply Adhesive

Apply a thin layer of tile adhesive to a small section of the wall using a notched trowel. Spread evenly and firmly press tiles into place, using spacers to align.

Step 2: Cut Tiles

Measure and mark tiles to be cut. Use a wet saw or manual cutter to cut tiles. File edges smooth. Cut tiles should be edged or centered, not slivered.

Step 3: Grout Seams

Once tile adhesive has cured per package directions, mix grout and apply over all seams, smoothing with a grout float. Wipe away excess.

Step 4: Seal Grout

After grout dries, apply grout sealer to protect from moisture and stains. Re-seal grout yearly.

Step 5: Finish Edges

Apply matching caulk along top edges, seams and around fixtures for a polished finish.

Work in sections for easiest installation. Allow tile adhesive to fully cure before grouting.

Grout Considerations

Choosing the right grout for your tile influences the overall look and durability of your backsplash. Consider color, texture and grout haze when selecting:

  • Color – Contrasting grout makes the tile pattern stand out. Matching grout minimizes the grid look.
  • Texture – Sanded grout works for wider grout lines. Unsanded grout is best for narrow grout lines.
  • Grout Haze – Epoxy grout resists staining and grout haze.

Test grout colors on a spare tile before use. Grout sealer is recommended for all tile grout to protect from stains.

How to Finish a Metal Backsplash

Installing a metal backsplash requires proper prep and care to avoid warps, dents and scratches. Here are some tips:

  • If installing a large stainless steel sheet, glue to wall studs for support. Foam insulation between metal and wall prevents bending.
  • For thin sheets, apply adhesive generously to the wall to affix in place. Use a level to ensure an even application.
  • Cut metal carefully using tin snips. File or grind edges smooth so they are not sharp.
  • Use caulk to seal all seams and edges for waterproofing and an attractive finish.
  • To combat grease splatter, attach a clear plastic laminate or acrylic shield to the lower portion of the backsplash.
  • Use a specialty metal cleaner to polish the backsplash after installation and avoid abrasive scrubbers.

How to Finish Alternative Material Backsplashes

Unique backsplash materials require special treatment to install properly:

Reclaimed Wood

  • Use construction adhesive to affix wood boards to the wall studs for support.
  • Apply waterproof polyurethane sealer to wood boards to resist moisture and stains. Reapply yearly.


  • Arrange pennies in desired pattern and glue onto mesh backing.
  • Hang mesh sheet on wall like a tapestry and seal edges with silicone caulk.

Broken China/Glass

  • Adhere broken china or glass pieces to marine vinyl mesh in your preferred design.
  • Mount mesh sheet to wall with adhesive and seal edges with caulk.

Always check that your alternative materials can withstand kitchen heat, grease and moisture before installing.

Backsplash Maintenance Tips

The way you care for your backsplash affects its appearance and longevity:

  • Seal porous stone and grout yearly to resist stains
  • Use mild cleaners and soft cloths only to clean backsplash
  • Rinse backsplash after cleaning – residue attracts dirt
  • Polish metal backsplash regularly to avoid buildup
  • Re-caulk seams when cracked or pulling away
  • Avoid hanging heavy items on backsplash

Catch spills quickly and clean often to keep backsplash materials looking their best.
