How to Remove Quartz Countertop Backsplash

Removing a quartz countertop backsplash can seem daunting, but with the right tools and techniques, it can be done successfully. Here is a step-by-step guide on how to remove a quartz backsplash without damaging the countertop.

Assessing the Backsplash

Before starting demolition, thoroughly inspect the backsplash installation.

  • Determine what type of adhesive was used. This will impact the removal technique. Common adhesives include silicone, mortar, and construction adhesive.
  • Look for any special fasteners such as screws or nails. Make note of their location.
  • Check for grout between the backsplash and countertop. This will need to be removed as well.
  • Examine the seam where the backsplash meets the wall. Remove any caulk or filler materials.

Gathering Necessary Materials

To safely remove the quartz backsplash, you will need:

  • Safety gear – gloves, eye protection, mask
  • Pry bar or putty knife
  • Hammer
  • Screwdriver or drill
  • Scraper
  • Mineral spirits or adhesive remover
  • Rags
  • Dustpan
  • Shop vacuum

Additional Supplies for Reinstall

If you plan to install a new backsplash, also gather:

  • Backsplash material
  • Adhesive
  • Grout
  • Caulk
  • Spacers

Removing the Backsplash

With your materials gathered, you can now start detaching the backsplash:

Step 1: Score the Seam

Run a sharp razor carefully along the seam between the backsplash and countertop. This helps break the adhesive bond. Be gentle to avoid scratching the countertop.

Step 2: Loosen Adhesive

Apply mineral spirits or adhesive remover along the scored seam. Allow it to penetrate for 5-10 minutes. This further dissolves the adhesive grip. Avoid the countertop surface.

Step 3: Pry Away Backsplash

Insert a pry bar or stiff putty knife into the seam and gently pry upwards. Apply even pressure to slowly pop the backsplash free.

Step 4: Remove Screws or Nails

Use a screwdriver or drill to remove any screws or nails holding the backsplash in place. Extract them fully to avoid scratching the quartz.

Step 5: Scrape Away Adhesive

Use a scraper to remove any excess adhesive from the wall and countertop. Avoid gouging the surfaces. Clean with mineral spirits and rags.

Step 6: Clear Out Grout

For cementitious grout, use a grout saw or rotary tool with a carbide bit. Carefully clear out grout from the seam and any joints.

Step 7: Vacuum Up Debris

Thoroughly vacuum up all adhesive, grout, and backsplash debris left behind. Use a soft brush attachment near the countertop.

Step 8: Fill Holes and Repair Wall

Fill any holes left from screws or nails with spackle. Use joint compound to patch and smooth damaged areas of the wall. Allow drying completely.

Preparing for New Backsplash

With the old backsplash removed, a few extra steps prepare the space for a new installation:

  • Clean the countertop and wall thoroughly with mineral spirits. Rinse and let dry.
  • Apply painter’s tape along the countertop edge to protect the surface.
  • Mark plumb vertical lines on the wall to align the backsplash. Use a level.
  • Dry fit the new backsplash pieces to ensure proper fit.
  • Mix up adhesive, grout, and caulk, and gather any spacers needed.

Installing the New Backsplash

Follow manufacturer’s instructions to install the new backsplash. Key steps include:

  • Apply adhesive to wall and/or backsplash pieces.
  • Press backsplash into place and ensure level placement.
  • Use spacers between pieces for consistent grout lines.
  • Allow adhesive to cure fully before grouting.
  • Grout the seams and joints. Wipe away excess.
  • Apply flexible caulk where the backsplash meets the countertop.
  • Clean and seal the backsplash once fully installed.


Removing a quartz backsplash can be successfully accomplished with care, patience, and the right techniques. Always work slowly and cautiously to avoid damaging the countertop. Thoroughly preparing the area will then allow for a smooth installation of a beautiful new backsplash.
