How to Remove Glass Backsplash Tiles

Removing glass backsplash tiles can seem like a daunting task, but with the right tools and techniques, it can be done safely and efficiently. Here is a comprehensive guide on how to remove glass backsplash tiles in your home.


Glass backsplashes bring a modern, sleek look to any kitchen or bathroom. However, trends change and sometimes those once-stylish backsplash tiles need to be removed and replaced. Taking out glass mosaic tiles or subway tiles takes more care and effort than removing ceramic or stone tiles. Glass is more delicate and needs special handling to avoid breakage.

With some basic DIY skills, most homeowners can remove a glass backsplash successfully. Having the right tools and materials on hand will make the job much smoother. Taking proper safety precautions is also essential when handling broken glass. Follow this step-by-step guide to learn how to remove glass backsplash tiles effectively.

Advantages of Removing a Glass Backsplash

Before diving into the removal process, let’s review some of the benefits of taking out an outdated or damaged glass backsplash:

  • Allows you to update the look of your kitchen or bathroom with new stylish backsplash tile. Glass backsplash tile colors and styles come and go out of trend.
  • Provides the opportunity to fix any water damage or mildew issues behind the backsplash.
  • Lets you access the wall behind the backsplash for repairs or alterations.
  • Removes broken or cracked tiles that are an eyesore. Damaged glass tile can also pose a safety hazard.
  • Creates a smooth blank canvas for installing a new backsplash design.

If your current glass backsplash is still in good condition, consider updating it with glass tile paint rather than a full tile removal and replacement project. But for those ready to swap it out for a fresh new backsplash, removing the old tile properly is the critical first step.

Tools and Materials Needed

Gather the necessary tools and materials before starting demo on a glass tile backsplash to make the process go faster and smoother:

Safety gear

  • Safety glasses – protect eyes from flying shards and dust
  • Gloves – leather gloves provide hand protection
  • Dust mask – prevents inhaling glass dust
  • Ear protection – demolishing tile can be loud

Demolition tools

  • Flat pry bar – for prying off tiles
  • Hammer – for breaking tile pieces
  • Utility knife – for scraping off adhesives
  • Putty knife – for scraping thinset

Additional supplies

  • Drop cloths – for protecting floors and countertops
  • Garbage bags – for removing tile debris
  • Shop vacuum – for ongoing cleanup
  • Tarp or sheet plastic – for containing dust
  • Spray bottle of water – for controlling dust
  • Tile remover solution – helps loosen adhesive

Step ladder or small scaffolding – to reach upper portions of backsplash

Gather all the necessary gear before starting the backsplash removal project. Safety comes first when handling broken glass. Eye protection, gloves, dust mask, and ear plugs or protective headphones are essential safety precautions. Have the proper tools on hand as well to make demolishing the tile easier and faster.

Preparing the Work Area

Before demolition begins, prep the workspace properly:

  • Clear countertops or remove items from walls adjacent to the backsplash.
  • Cover surfaces below the backsplash with drop cloths to protect from falling debris. Use plastic sheeting if removing a full wall of subway tile or mosaic tile backsplash.
  • Have a shop vac ready to frequently clean up glass shards and dust.
  • Place a step ladder or small scaffolding in front of the backsplash to reach the top area.
  • Sweep the backsplash tiles well to remove any dirt and debris.

Proper prep prevents damage to cabinets, countertops and floors during the tile removal process. Prepping the workspace also makes cleanup faster with everything protected and contained.

Removing Glass Backsplash Tiles

With the workspace prepped, it’s time to start demolishing that outdated or damaged glass backsplash. Here are the key steps:

1. Score grout lines with a utility knife

Use a sharp utility knife to score along the grout lines surrounding each tile. Don’t try to cut all the way through the tile. Just scoring the grout line helps weaken it for tile removal.

2. Heat tiles with a blow dryer or heat gun

Heating the tiles helps soften the tile adhesive behind them. Run a blow dryer or heat gun over the surface of the tiles. Heating them up makes prying off the tiles easier.

3. Start prying off tiles

Wearing safety glasses and gloves, use a flat pry bar tool to begin working the tiles off the wall. Insert the pry bar into grout lines to lift tiles off. Apply even pressure to minimize tile breakage.

4. Remove stubborn tiles with hammer taps

For tiles firmly stuck, use light hammer taps on the pry bar to help loosen the adhesive’s grip. Start at the bottom and work upward to prevent slipping tiles from above.

5. Use tile remover solution on tough adhesive

Spray or spread tile remover solution on adhesive that’s resisting removal. Follow the product directions in terms of set time before prying. Solvents help dissolve the adhesive bond.

6. Scrape off remaining thinset adhesive

Once all tiles are removed, use a putty knife to scrape off any remaining thinset mortar adhesive. Get it as smooth as possible in preparation for the new backsplash.

7. Clean up debris thoroughly

Carefully pick up any intact tiles and broken shards and place them in a garbage bag. Use a shop vac and damp cloth to clean up all dust and debris from the removal process.

Work slowly and carefully when prying off each tile to avoid excessive cracking and shards. Wearing safety gear is critical when handling broken glass to avoid cuts and eye injuries.

Disposing of Glass Tile Debris

Removed glass backsplash tiles most likely cannot be salvaged or recycled due to their broken state. Follow these recommendations for safe disposal:

  • Place shards and intact tiles in heavy duty garbage bags. Seal bags fully.
  • Label bags as broken glass to warn sanitation workers.
  • Transport bags carefully to avoid ripping. Place smaller shards in boxes first.
  • Check for local hazardous waste disposal guidelines regarding broken glass.
  • If amount is minimal, regular curbside pickup may be okay after sealing shards in boxes.

Sweep the area well after disposing of the glass tiles. Inspect for any remaining shards that could cause cuts. Glass can easily embed in shoes and hands during removal and cleanup. Proper debris disposal reduces safety risks.

Preparing the Surface for New Tiles

Once all old backsplash tile and adhesive has been removed, inspect the wall surface:

  • Repair any damaged drywall areas so they are smooth and stable.
  • Fill any divots, holes or cracks with joint compound and sand smooth.
  • Use an adhesive remover solution to clean off any lingering thinset residue.
  • Wipe the entire surface down to remove dust and debris.
  • Fill grout lines level with surrounding wall areas if needed.

The goal is to end up with a flat, structurally sound substrate for the new backsplash installation. Check for any moisture issues behind the wall that need resolution before putting up fresh tile.

Tips for Easier Glass Backsplash Removal

  • Remove any screws holding backsplash edge trim and outlets covers first.
  • Start removal at the top center of the backsplash and work downward.
  • Apply painter’s tape along the edges to prevent damaging adjacent surfaces.
  • Try scoring the grout lines the day before for an easier pry off.
  • Use isopropyl alcohol or acetone to help dissolve stubborn adhesives.
  • Go slow and careful when prying and lifting off tiles.
  • Wear knee pads to protect knees when working low to the ground.
  • Have a second person available to assist with removal and cleanup.

Removing glass backsplash tile takes time, patience and care. But with the proper tools and prep work, a homeowner can tackle this project successfully. Always wear safety goggles, gloves and a mask when demolishing tile. And take measures to contain the glass dust and debris during removal and cleanup.

Frequently Asked Questions About Glass Backsplash Removal

Here are answers to some of the most common questions about how to remove glass backsplash tiles:

Can I just apply new tile over my existing glass backsplash?

It is not recommended to install new tiles over an existing glass backsplash. The glass will likely cause unevenness, and it won’t adhere well to the new tiles. Removing the original backsplash ensures a smooth, uniform surface for the new installation.

How do I remove the mastic adhesive from glass tile?

Use a mastic remover solution or isopropyl alcohol applied with a scraper to gradually dissolve the adhesive. Avoid using excessive force which can gouge the wall. Thoroughly rinse the wall afterward.

What is the easiest way to get glass tiles off the wall?

Heating the tiles first with a blow dryer or heat gun softens the adhesive which makes prying off each tile much easier. Use a utility knife to score grout lines before heating and prying.

Can I hammer off glass backsplash tiles?

Use very light hammer taps on a flat pry bar to help loosen stubborn tiles after heating them. Excessive hammering can lead to tile shattering or wall damage. Go slow and careful.

Is a glass backsplash hard to keep clean?

Glass tile can actually make backsplash cleanup easier than stone, metal or porous tile. Glass does not absorb stains and wipes clean easily. Use a gentle cleaner and soft sponge or microfiber cloth.

How should I protect myself during removal?

Always wear safety goggles, leather gloves, closed-toe shoes, long sleeves and pants. Use a dust mask and ear protection as well. Work slowly and carefully when handling broken glass.

What tools do I need to take down a glass mosaic tile backsplash?

A utility knife, flat pry bar, hammer, heat gun, mastic scraper, vacuum, drop cloths, and safety gear are the essential tools needed. Have tile remover solution on hand too.
