Can You Put Backsplash Over Backsplash?

Installing a backsplash is one of the best ways to add visual interest and style to your kitchen. But what if you already have an existing backsplash and want to update the look? Can you install a new backsplash right over the old one?

What is a Backsplash?

A backsplash is a protective surface installed on the wall behind sinks, stoves, and countertops. Backsplashes are typically made of tile, metal, glass, or stone. The main purposes of a backsplash are:

  • Protect the walls from water damage, grease splatters, and other cooking messes. The backsplash takes the brunt of the abuse so your painted walls don’t have to.
  • Add decorative flair to the kitchen. Backsplashes come in endless style options, allowing you to customize the look of your space.
  • Tie together cabinetry, countertops, and appliances into a cohesive design. The backsplash serves as an accent that brings all the elements together.

Reasons for Wanting to Replace an Existing Backsplash

There are several reasons you may want to update or replace your existing kitchen backsplash:

You Want a New Look

Style trends and personal tastes change over time. Even if your current backsplash is in good shape, you may want to swap it out for something more modern or aligning with your new design aesthetic. For example, you may want to replace a dated 1980s spackle ceramic tile backsplash with on-trend subway tiles or modern glass mosaics.

It’s Damaged or Stained

Kitchen backsplashes take a lot of wear and tear. Over time, the surface may become stained, scratched, chipped, or cracked. Heavy damage makes the backsplash an eyesore, so installing a fresh new one makes the space look revived.

It Doesn’t Match Anymore

If you remodel other areas of your kitchen, the old backsplash may look out of place. For example, if you replace laminate countertops with sparkling quartz, the backsplash may appear dingy or clash with the updated look. Putting in a backsplash that complements the new countertops and cabinets will pull the whole new design together.

You’re Tired of Looking at the Old One

Even if it’s in fine condition, staring at the same backsplash day in and day out can get monotonous. Installing something fresh and different adds excitement and beauty to a high-traffic area of your home.

Can You Install a New Backsplash Over the Old One?

The short answer is yes, in many cases, you can install a new backsplash right over the existing one. There are several benefits to this layered approach:

It’s Faster and More Affordable

Removing an old backsplash takes time and labor, which drives up costs. Covering it is often the quicker, more budget-friendly route. Tile removal can kick up a lot of dust too, making cleanup more intensive.

It Prevents Damage to the Wall

Taking out the old backsplash often damages the drywall behind it. Screw holes, adhesive residue, and dented or scraped surfaces usually need patching and smoothing. Leaving the original backsplash intact avoids this extra repair work.

It Provides a Smoother Surface

Existing tile forms an even base for applying the new backsplash. Trying to apply tile over damaged drywall with gouges and divots from the tear-out process results in a bumpier, less uniform finish.

It’s One Less Messy Step

Prying off tile and scraping away adhesives results in a layer of grime and dust to clean up. Skipping the removal process keeps the project tidier.

However, there are a few caveats to be aware of:

Installation Takes More Planning

You need to carefully prepare the existing surface for adhesion and account for the extra layer of thickness. Proper prep work is crucial for successful installation.

The Final Result May Be Uneven or Bulky

Depending on the materials, you could end up with a visible ledge or extra thickness between the countertop and backsplash. The two layers combined might push the new backsplash outward beyond the plane of the cabinets. Carefully selecting thin materials and proper trim pieces helps offset these issues.

Old Grout Lines May Show Through

Grout lines from the previous backsplash could be faintly visible underneath translucent or thin materials like glass tile or polished stone. This may or may not bother you aesthetically.

Long Term Durability May Be Reduced

Adding weight and layers could cause the materials to separate over time. Proper installation helps, but it’s not guaranteed to last as long as a backsplash adhered directly to the wall.

Accessing Electrical or Plumbing May Be Harder

If there are outlets, switches, or pipes behind the backsplash area, covering over them with two layers of material makes access trickier. It’s not impossible, but something to keep in mind.

How to Install a New Backsplash Over the Old One

Installing over an existing backsplash is possible, but it takes careful prep and precision. Here are some tips for success:

Choose the Right Materials

Pick tiles or panels made from thin materials to avoid excessive buildup. Mosaic tiles, metal sheets, and grout-less materials like stone slabs work well. Avoid heavy natural stone tiles or large format tiles, which add more weight.

Prep the Surface

The existing backsplash must be cleaned, smoothed, and prepped to form a solid adhesion base. Scrape off old caulk. Sand grout lines flat. Address any cracked or missing tiles. Clean with an abrasive degreaser.

Apply a Sealer or Membrane

Priming the old backsplash with a specialty sealer or waterproofing membrane enhances adhesion. This extra layer also smooths over grout lines and tile seams.

Use the Correct Adhesive

The adhesive needs to be formulated for going over existing surfaces. A robust mortar or heavy-duty mastic works better than basic thinset. Follow directions closely.

Adjust Outlets or Switches

Any outlets or switches on the backsplash wall may need extensions or spacers to accommodate the extra thickness. This avoids a gap behind them once the new tile is applied.

Add Trim Pieces

Flexible caulk or trim pieces around the outer edges provide clean transitions between the countertop and new backsplash. This compensates for any change in thickness.

Grout and Seal the Tile

Use quality grout and apply a penetrating sealant made for backsplashes. This protects the finish and prevents stains. Caulk along the seams for water resistance.

Ideal Materials for Installation Over Existing Backsplashes

Certain backsplash materials are better suited to installing over a previous backsplash:

  • Glass mosaic tiles: Small mosaic tiles made of glass, metal, or stone come mounted on mesh sheets. This allows them to conform over uneven surfaces and grout lines easily. The mesh mounting also compensates for thinner existing tiles.
  • Metal backsplashes: Stainless steel, copper, brass, and aluminum backsplashes come in thin, lightweight sheets. Metal is durable, moisture-resistant, and installs cleanly over existing materials.
  • Thin porcelain, ceramic, or stone: While natural stone slabs are thick and heavy, thinner sliced versions of porcelain, ceramic, or stone maintain durability without the weight. Use panel pieces, not heavy stone tiles.
  • Jointless sheets: Materials like Dekton, Neolith, or Durat offer the look of stone without visible joints or grout lines. The seamless sheets install easily over old backsplashes.
  • Removable backsplashes: Some peel-and-stick, snap-together, or magnetized backsplash panels allow easy installation directly over old tiles. This also makes them simple to remove later if needed.

Professional Installation Tips

For best results, it’s wise to hire a professional tile installer for this type of project. Experienced pros have the skills to:

  • Evaluate the existing backsplash and determine if it needs repair first
  • Make any necessary adjustments to outlets or switches
  • Properly prep and seal the old surface
  • Strategically place trim and transition pieces between countertops and backsplash
  • Apply the optimum adhesive for a durable bond
  • Achieve the flattest, smoothest finish possible over two layers
  • Grout and seal the new backsplash perfectly

This expertise ensures your project goes smoothly and the end result looks cohesive and professionally done. The cost is usually well worth it for long-lasting quality and beauty.

Risks and Downsides to Installing Over an Existing Backsplash

While covering an old backsplash with a new one does offer some perks, drawbacks are also a possibility:

  • Uneven surface areas where old grout lines or tile edges create noticeable bumps under the new backsplash
  • Ghosting where old tile patterns faintly show through lighter or more transparent new materials
  • Potential for moisture getting trapped between the tile layers, which could compromise adhesion over time
  • Difficulty with future repairs or updates if the wall needs opening behind the layers of backsplash
  • Extra time needed for preparatory steps prior to installation
  • Limitations on material types and sizes – very heavy or thick tiles may not be feasible

Careful prep work and using suitable materials minimizes these risks. But some amount of compromise may be necessary depending on the specifics of your project.

When a Complete Tear-Out is Recommended

In certain situations, it’s better to fully remove the old backsplash before installing a new one:

  • If the existing backsplash is badly damaged – cracked tiles,missing grout, rich gouges, or seams separating
  • When switching to a drastically different size or type of material – ex. Large format tiles over mosaics
  • If there are problems with the wall underneath – moisture damage, cracks, crumbling drywall, or adhesive issues
  • When accessibility behind the backsplash is needed – to wiring, plumbing, outlets, or wall framing
  • To maximize longevity by adhering directly to the wall surface rather than another layer of tile
  • For the most seamless, integrated look from countertop to backsplash, with no edges or ledges

A full tear-out process requires more time and labor. The destruction involved also creates more dust and debris to contain. But you gain the benefits of a fresh, clean start and direct wall adhesion.

The Best Option Depends on Your Specific Situation

Whether installing over or replacing your existing backsplash, consult with a professional to determine the right choice. Factors like budget, the current condition of the tile and walls, your material preferences, and accessibility needs all impact the ideal approach.

With proper planning and care, refreshing your kitchen with a new backsplash overlay is certainly achievable. But for some situations, it may be worth the investment to clear all existing materials away and start from scratch. Ultimately the project scope and your vision for the finished look will decide which path is right for you.

Frequently Asked Questions About Installing a New Backsplash Over an Existing One

Here are answers to some common questions homeowners have about backsplash installation:

Is it hard to install a backsplash over an existing one?

It’s more challenging than installing directly on the wall, but not necessarily difficult with the right materials and preparation. Thoroughly cleaning and scuffing up the old backsplash surface ensures proper adhesion. Using smaller tiles or panels makes fitting them over grout lines easier. Good quality thinset mortar and precise application helps minimize any bumps or waviness. Patience and care makes the process very doable.

Do you have to take the old backsplash off to put a new one on?

It is possible to install right over an existing backsplash, saving the time and mess of tearing the old one out. As long as the original backsplash is in good condition and thoroughly prepped, the new materials can adhere to it successfully. Based on the tile choices, this may result in some unevenness but is often minimal.

Should you replace backsplash when replacing countertops?

Many designers recommend replacing the backsplash whenever you replace countertops. The new countertop often won’t coordinate well with the old backsplash. By choosing new finishes for both, you create a unified, up-to-date look. If the current backsplash is still in great shape, consider materials that work with it instead of automatically assuming it needs replacement.

Can you put tile over existing tile backsplash?

Yes, you can install tile over an existing tile backsplash. Smaller tiles or mosaic sheets are easiest to apply over the grout lines. Prepping correctly provides the smooth, clean surface needed for good adhesion. Use a high-quality thinset mortar meant for tiling over existing surfaces. The right preparations and materials make overlaying tile backsplash possible.

How do you prepare old tile for new tile?

Proper prep of old tile before tiling over it includes:

  • Clean thoroughly with a degreasing tile cleaner to remove grease, oils and waxes
  • Smooth or sand grout lines to eliminate ridges or bumps
  • Scrape out old caulk and re-caulk seams if needed
  • Fill any cracks or chips with patching compound
  • Scuff up the glossy tile surface using sandpaper or a grinding stone for better adhesion
  • Apply a tile sealer or membrane designed for adhesion to existing surfaces

Following these important steps allows the new tile to bond correctly to the old surface beneath it.


Installing a new backsplash over your existing one is an effective way to refresh the look without undergoing a full tear-out. With careful planning, proper materials, and skillful installation, a backsplash overlay can give your kitchen an updated, cohesive style. However, some situations do warrant completely removing the old backsplash prior to installing a new one. Consult with experts to determine if overlaying or starting fresh is the right approach for your specific kitchen. With the right approach, you can achieve a backsplash makeover that makes your kitchen look brand new again.
