How to Put on a Tile Backsplash

Installing a tile backsplash in your kitchen or bathroom can add visual interest and protect your walls from water damage and stains. With some planning and the right materials, putting in a tile backsplash is a manageable weekend project for a DIYer. We will walk you through the entire process step-by-step, from preparing your work surface to grouting and sealing your finished tile.

Choose Your Tile

There are endless options when it comes to selecting a tile for your backsplash. Consider the look you want and your budget. Some popular choices include:

  • Ceramic or porcelain: Affordable option; available in a huge range of colors, sizes, and finishes. Durable and water-resistant.
  • Glass: Provides a shiny, sleek look. Translucent options available. More expensive than ceramic or porcelain.
  • Metal: Gives an industrial, modern look. Great durability but on the pricier side.
  • Stone: Natural stone like marble, travertine, or granite can create a high-end, luxurious backsplash. Need to be sealed properly.
  • Mosaic: Small tiles or pieces arranged in a pattern. Allows creativity and visual interest. Grouting can be tedious.

Make sure to buy a few extra tiles to account for breakage during installation. Keep your receipt in case you need to return unused tiles.

Gather Your Materials

In addition to the tile itself, you will need:

  • Adhesive: Choose an adhesive suitable for your tile type. Many thinset mortars work for ceramic, porcelain or stone.
  • Grout: Pick a grout color that complements your tile. Unsanded grout is best for narrow grout lines.
  • Trowel: Look for a trowel with notches suited to your tile size. This ensures proper adhesive coverage.
  • Spacers: Plastic spacers maintain even grout lines between tiles.
  • Grout float: For smoothing and shaping grout lines.
  • Grout sealer: Protects grout from stains.
  • Wet saw or tile cutter: For precise tile cutting. A snap tile cutter works for straight cuts.
  • Safety gear: Gloves, goggles, knee pads, etc.

Purchase any missing tools. Check that your work surface is clean, dry, and free of grease or debris. Remove outlet covers. Protect nearby surfaces with drop cloths.

Prepare Your Surface

Make sure your backsplash area has a smooth, uniform surface for the tile to adhere to.

  • For drywall, scrape off any loose paint or wallpaper. Fill any holes or imperfections with drywall joint compound. Sand smooth. Prime before tiling.
  • For plywood, use exterior grade. Avoid oily woods like pine. Prime and seal surface.
  • For existing tile, scuff up the glossy surface with sandpaper. Clean thoroughly before applying new tile.
  • For concrete or plaster, fill cracks with patching compound. Smooth uneven areas.

The surface should be dry and free of wax, grease, dust, soap scum, or peeling paint. Paint with primer to improve adhesion.

Plan Your Layout

Map out your tile layout on the wall before installing. This will help ensure the tile rows are evenly spaced and aligned.

  • Mark the center point of your backsplash area and use a level to draw plumb vertical and horizontal lines.
  • Dry fit tiles along the horizontal line using spacers, working symmetrically outward from the center. Adjust to avoid narrow cut pieces at the edges.
  • Hold tile sheets or foam board up to map out the entire layout. Mark for electrical outlets.
  • For decorative patterns like herringbone, sketch the layout ahead of time.

Adjust the placement as needed before installing with adhesive. Planning ahead ensures a professional looking finished product.

Apply the Adhesive

With your layout planned, it’s time to start tiling:

  1. Spread a thin layer of adhesive on a small section of the wall using a notched trowel held at a 45 degree angle.
  2. Apply only as much adhesive as you can cover with tile before it skins over. Different adhesives have varying open times.
  3. Press tiles firmly into the adhesive using a slight twisting motion. Use spacers to maintain consistent grout lines.
  4. Check periodically that the back of each tile has made solid contact and is fully embedded.
  5. Scrape off excess adhesive before it dries. Continue working in small sections until the area is fully tiled.

Take your time to apply adhesive and set tiles correctly. The tile should not easily detach from the wall. Immediately wipe away any excess adhesive or thinset from the tile face using a damp sponge.

Cutting Tiles Precisely

Use a wet tile saw to cut ceramic, porcelain, or stone tiles for a precision fit. For mosaic sheets, a snap tile cutter often works well for straight cuts.

  • To use a wet saw:
    • Mark each tile with a pencil where you want to cut it.
    • Adjust the tile guide and carefully run the marked tile through the saw.
    • Make slow, even passes for each cut to avoid cracks or chips.
    • Use a grinder to smooth any rough edges on cut tiles.
  • To use a snap tile cutter:
    • Score the tile by running the cutting wheel firmly along the marked cut line.
    • Position the tile over the edge of the tile cutter table.
    • Press down firmly on both sides of the tile to get a clean break along the scored line.

Always wear safety goggles when cutting tile. Cut tiles can have very sharp edges. Make cuts slowly and deliberately for best results.

Grouting Your Tiled Backsplash

Once your tile adhesive has cured per manufacturer instructions, typically 24-48 hours, you can grout your backsplash:

  1. Apply grout sealer to the tile to prevent staining and simplify cleanup. Wait 15 minutes and wipe away any excess.
  2. Using a grout float or rubber grout float, spread grout over the tile surface, pressing into joints. Hold the float at a 30° angle like frosting a cake.
  3. Go slowly and make sure joints are fully packed to avoid voids or cracks as the grout dries.
  4. Let the grout firm up slightly, then use a damp sponge to smooth and shape joints. Rinse the sponge frequently.
  5. Allow grout to cure per manufacturer recommendations, then polish the tile surface with a soft cloth.

Avoid wiping or rinsing too early – this can pull grout out of the joints. Take time during application for a professional grouted finish.

Caulking and Sealing

Finish up your backsplash installation:

  • Apply a silicone caulk along the joints between the countertop/sink and the edges of the tile. Smooth with a wet finger. Allow to fully cure.
  • Use a grout sealer to protect grout lines from stains. Two coats are recommended for optimal sealing capability.
  • If using natural stone tile, apply a stone sealer to the entire tiled area to guard against staining and etching. Reapply yearly.
  • Replace electrical outlet covers, caulk around pipes, vents, or fixtures intersecting the tile.
  • Clean the area well using a pH neutral cleaner and soft cloth. Rinse any soap residue.

Take good care of your backsplash and it will maintain its beauty for years to come!


What kind of tile is best for kitchen backsplash?

For kitchens, glazed ceramic, porcelain, or natural stone tiles stand up well to heat, grease, and moisture. Glass tile can also be used if care is taken not to slam pots and pans into it.

How difficult is it to install a tile backsplash?

Putting up a tile backsplash is considered an intermediate DIY project, but can certainly be tackled by an amateur willing to take their time and follow each step carefully. Patience and attention to detail are key.

Can you put tile backsplash directly on drywall?

Drywall alone usually cannot support the weight of tile. It’s recommended to install cement backerboard, HardieBacker, or another tile backing material on top of the drywall to provide a stable surface for tiling.

What thickness of tile is best for backsplash?

A tile thickness of 4.5-6mm is ideal for backsplashes. Thinner tiles like 3-4mm can crack more easily. Go thicker for floor installations or commercial projects.

How long does tile adhesive take to dry?

Thinset mortars generally reach an initial set in 6-8 hours but need a full 24-48 hours to cure fully. Check manufacturer guidelines for recommended cure times.


Installing a beautiful, long-lasting tile backsplash boosts function and style in any kitchen or bathroom. With proper planning, materials, and techniques, you can achieve stunning results and increase the value of your home. Patience and attention to detail are vital for correctly applying adhesive, proper spacing, precision cutting, full grout coverage, and sealing. Our guide covers the key steps for a successful DIY tile backsplash project from start to finish. Do your research, gather the necessary supplies, and don’t rush the process. Take your time and you’ll have a backsplash you can enjoy for many years.
