  • Place and space tiles – Press tiles into thinset, use spacers to leave even grout lines.
  • Grout application – After tiles cured, apply grout between tile joints, then wipe clean.
  • Seal grout – Apply grout sealer once grout has dried for waterproofing.
  • Enjoy your new backsplash! – Let tiles fully cure for a few days before regular use.

The rest of this guide will walk through these steps in more detail, as well as provide tips for choosing your tile, cutting and pattern layout, grouting, and ongoing backsplash maintenance. Let’s dive in!

Drywall Inspection and Preparation

The first step when tiling backsplash on drywall is ensuring the drywall surface is properly prepared. Take time to thoroughly inspect the area and address any issues to ensure your tiles will have a solid base:

Inspect Drywall for Damage

Look over the entire backsplash area and check the drywall for any cracks, chips, gouges, or other damage. Damage should be repaired prior to tiling – fill small holes with drywall compound, larger areas may need a drywall patch. Ensure repairs are smooth and flat.

Check for Moisture Damage

Make sure there are no areas of the drywall that show signs of water damage or moisture exposure. Look for sagging, warped, or discolored drywall. Any moisture issues need to be fully resolved before attempting to tile.

Remove Outlets and Switches

Take out any electrical outlets, light switches, or fixtures that are in the backsplash area – these can be easily reinstalled after tiling. Cut tiles around them for removal.

Clean Surface Thoroughly

Clean the entire backsplash area with soap and water, then a degreaser if needed. Remove any existing wallpaper, adhesive, paint flakes, dirt, oil, or grease so tiles can properly adhere.

Seal and Prime

Seal the drywall with a PVA primer or drywall sealer according to manufacturer directions. This provides a uniform surface and prevents absorption of adhesives and moisture.

Fill Gaps and Imperfections

Use drywall joint compound or spackle to fill any small gaps, cracks, nail holes, or other imperfections for a smooth finish. Sand once dry.

Once the drywall is prepped, you can move onto the fun part – choosing and preparing your new tile backsplash!

Backsplash Tile Materials and Design Planning

One of the enjoyable parts of a new backsplash is selecting your tile. Take time to consider the style, color, and texture options to find the perfect tiles for your space. Planning your backsplash design is also an important early step.

Choosing Backsplash Tiles

Some of the most popular options include:

  • Ceramic or Porcelain – Classic styles and finishes, ceramic is more porous than impervious porcelain. Glazed versions offer easy cleaning.
  • Glass Tile – Bring shiny, sleek visual interest with glass backsplashes. Often use mosaic sheets.
  • Metal Tile – Tin, stainless steel, and copper tiles lend an industrial vibe. Stand up to heat and moisture.
  • Stone Tile – Marble, travertine, and granite backsplash tiles provide natural elegance. Need sealing.

Consider the room’s decor, countertop and cabinet materials, appliances, and whether the space is contemporary or traditional when selecting tile style, colors, and textures. Also factor in your budget and skill level, as some statement tiles can be more difficult to cut and install.

Design and Tile Layout

Once you’ve chosen your tiles, mapping out the design is key. Measure the backsplash area walls and use graph paper or backsplash design software to experiment with different tile layout patterns. This allows you to visualize full and partial tiles, and ensure you purchase enough quantity. Decide if you want a more uniform grid, an offset brick pattern, chevron herringbone, or artistic mosaic design. Plan tile placements around sinks, outlets, corners, and edges. Having a set tile plan will make for smooth installation.

Tools and Materials for Tiling Backsplash

Gathering the right tools, tiles, and materials is crucial for proper installation. Be sure to get high quality products designed specifically for tiling. Recommended supplies include:

Tiling Tools

  • Tile wet saw or manual cutter
  • Rubber tile spacers
  • Rubber trowel for spreading thinset
  • Grout float for applying grout
  • Sponges and buckets
  • Safety gear – gloves, goggles, knee pads


  • Backsplash tiles
  • Thinset mortar adhesive
  • Grout
  • Grout sealer
  • Caulk/silicone sealant

For the specific quantity needed, measure your backsplash space then calculate tile square footage, adding 10-15% extra for cuts and waste. Most tile distributors have planning guides on their websites as well. Allow time for shipping tiles and other materials. Once your supplies are ready, the real hands-on work begins!

Cutting Backsplash Tiles

Cutting ceramic, porcelain, or stone backsplash tiles take some skill and patience, but is very doable for DIYers. Always use sharp blades designed for your tile material. The two main options are:

Wet Saw – Electric tool with a water-covered diamond blade that accurately cuts tiles. Gives smooth, clean cuts. Best for mosaics, large format tiles, and specialty shapes.

Manual Tile Cutter – Compact and affordable, uses a carbide wheel scorer and snap action to cut tiles. Good for straight lines and simpler jobs. Limit on tile size/hardness.

Follow tile saw operating directions closely for safety and proper use. When using a manual cutter, score tiles evenly with 3-4 passes before snapping. Always wear safety goggles and gloves. Cut tiles accurately to your planned measurements and layout. It’s smart to do a few practice cuts on scrap tiles first to get the hang of it. Cut edges will be concealed by grout lines and caulk.

Be sure to also notch out small V or L shapes from tiles that need to fit around electrical outlets, plumbing fixtures, corners, and other obstacles. It takes time, but careful tile cutting is what ensures a professional looking finished product.

Installing Backsplash Tiles on Drywall

Once your backsplash tiles are cut, it’s go time for installing them onto the prepped drywall. Follow these steps closely:

Mix Thinset Mortar

In a bucket, mix thinset adhesive powder with water per product instructions, to a loose toothpaste consistency. Only mix what you can use in 30-60 minutes.

Apply Thinset to Wall

Use the notched edge of a rubber trowel to spread a thin, even layer of thinset adhesive onto a small section of the backsplash area, about 2 square feet.

Place Tiles into Thinset

Following your tile layout design, firmly press tiles into the adhesive, using spacers between tiles for consistent grout line spacing.

Check Levels and Alignment

Look over the tiles as you go and use a level to ensure they are plumb and lined up evenly. Adjust as needed while adhesive is still wet.

Clean Up Excess Thinset

Wipe away any excess thinset with a damp sponge before it dries. Do final checks on tile spacing and alignment as you go. Let thinset fully cure per manufacturer directions before grouting.

Take your time during installation and periodically review positions vs your planned layout. Allow tiles to set undisturbed while thinset cures. Clean tools and excess thinset as you go. Doing a small section at a time is ideal for easier handling. Soon you’ll be ready for grouting!

Grouting and Sealing the Backsplash

Adding grout between the tiles is the next vital step that truly finishes off your new backsplash. Follow this grouting process:

Mix Grout

Prepare grout per package instructions, to a thick, peanut butter-like consistency. Applying grout will be easiest using a rubber grout float tool.

Apply Grout Between Tiles

Using the float, spread grout over the entire backsplash area, forcibly packing it deep into the joints between tiles. Remove any excess.

Wipe and Clean Grout

Once the section has been fully grouted, use a damp sponge to gently wipe diagonally across the tiles. This smoothes the joints and cleans any grout residue from tile faces. Rinse sponge frequently.

Allow Grout to Dry

Let grout dry completely, which normally takes 24-48 hours. Avoid excess moisture while curing. Run any fans or dehumidifiers if needed.

Seal Grout

Once fully cured, apply a grout sealant using a small paintbrush. This waterproofs the grout lines for easier cleaning.

Always use approved grout and sealant for your specific tile material. Take time to smoothly apply grout and wipe tiles clean for professional results. With the finishing touches completed, be sure to let the area rest for several days before regular use and cleaning. Soon you’ll be enjoying your stylish new backsplash!

Maintaining and Cleaning Tiled Backsplash

Once installed and grouted, a tiled backsplash needs simple periodic maintenance to keep it looking like new:

  • Use a pH neutral cleaner for regular washing, rinsing any soap residues. Avoid harsh cleaners.
  • Reapply grout sealant 1-2 times per year to protect from moisture and grime.
  • Check for any cracked or missing grout over time and repair as needed to prevent damage.
  • Be extra careful not to nick tiles with cookware or utensils. Use cutting boards.
  • Clean up spills promptly to prevent staining of grout lines.
  • Consider using a backsplash-height layer of clear glass or acrylic to protect speciality tiles over work areas.
  • Avoid hanging heavy items on backsplash that could loosen tiles.

Applying a tile backsplash brings function and beauty to kitchen and bath walls. With smart preparation of the drywall, high quality materials, and careful tile installation, you can end up with a stunning, lasting backsplash. Just take it step-by-step and don’t be afraid to ask for help from experienced tiler friends. Soon your drywall will be covered in stylish, low-maintenance tiles that upgrade your space for years of enjoyment.

Frequently Asked Questions about Tiling Backsplash on Drywall

What type of tiles can be installed on drywall?

Most types of backsplash tiles can be applied directly onto drywall if proper preparation and installation techniques are used. Common options are ceramic, porcelain, glass, and stone tiles. Ensure they have low water absorption. Mosaics with mesh backing sheets are great drywall choices.

Do you need to use cement board instead of drywall?

Cement backer board offers strength for tile underlayment but drywall can work fine for most backsplash areas with proper prep and thinset mortar adhesives made for drywall. Exceptions are areas with direct water contact like tub/shower surrounds, where cement board is strongly advised.

Can you just use construction adhesive instead of thinset?

No, thinset mortar adhesive is specially formulated for bonding tiles to surfaces. Construction adhesives lack the bonding properties needed for a durable bond and are not recommended. Make sure to use thinset suitable for drywall.

How long does the thinset mortar take to cure before grouting?

Exact thinset cure times depend on the product used, but most require 16-24 hours of curing before grouting the tiles. This allows the thinset to fully harden and develop a strong tile bond. Check manufacturer directions.

How soon can I use the backsplash after tiling?

It’s best to avoid heavy use and moisture on newly tiled backsplash for at least 2-3 days. This gives thinset, grout, and sealants optimal time to fully cure before subjecting the area to cooking, cleaning, and regular use.

What’s the best way to cut holes for outlets and fixtures?

For rounded openings like outlets, use a rotary tool with a tile bit to drill connecting holes and then carefully knock out the remaining sections with a hammer and sculpted tool. For square openings, mark the shape and use a wet saw.

My tiles are cracking – what did I do wrong?

If tiles start to crack after installation, the likely causes are either incorrect thinset mortar used or tiles not fully supported because of uneven drywall. Highly rigid tiles also need proper lippage control. Unfortunately cracked tiles need replacement.


Installing a tile backsplash over existing drywall opens up many possibilities for refreshing the look and utility of your kitchen or bath. Armed with the information in this guide, you can tackle this project with confidence. The keys are proper planning, top quality tile and installation materials, taking time with careful tile cutting, getting the thinset mortar layer just right, full grout coverage in the joints, and sealing. While it takes some work, the final result is well worth it. Your stylish new backsplash tile on drywall will enhance your space for many years of beauty and easy cleaning!
