Peel and stick backsplashes provide a quick and easy way to update the look of your kitchen. Made from vinyl or other materials, they have an adhesive backing that allows them to be applied directly to your wall surface. However, over time peel and stick backsplashes may start to peel, crack, or lose adhesion. Fixing them is possible with the right techniques and materials.
Assessing the Damage
Before attempting any repairs, you’ll need to fully assess the condition of your failing peel and stick backsplash.
Check for Loose Areas
Thoroughly examine the entire backsplash, pressing gently on areas to check if they are still firmly adhered to the wall. Make note of any sections that are loose, peeling up or seem like they will easily detach.
Look for Cracks
In addition to loose spots, check for any cracks or splits in the vinyl material itself. Use a flashlight to better see small cracks. Determine if the cracks are limited to the surface or if they go all the way through the vinyl.
Test Adhesion
Try gently prying up different areas of the backsplash with your fingernail or a plastic spackling knife. See how easily the vinyl comes up, which can indicate poor adhesion.
Identify Failure Points
Determine if certain spots, seams or edges of the backsplash are failing more than others. This can clue you in on installation issues or environmental factors.
Pinpoint Potential Causes
Think about why the backsplash is failing. Has it reached its normal lifespan? Is humidity causing it to release from the wall? Did improper prep or installation cause it to fail prematurely? Understanding the cause will help prevent future issues.
Decide on Repair or Replace
Based on the amount of damage, you’ll have to determine whether you can salvage the backsplash with repairs or if full replacement is necessary. If failures are widespread, replacement may be best.
Cleaning and Prepping the Surface
Once you’ve thoroughly inspected the backsplash and determined the feasibility of repairing it, proper prep work is essential for achieving a successful, long-lasting fix.
Remove Loose Sections
Carefully peel off any large sections that are bulging or almost completely detached. Avoid tearing the vinyl if possible. Scrape off any old adhesive that remains stuck to the wall.
Clean the Wall Surface
Wash the entire backsplash area with a non-abrasive cleaner and water. This removes grease, grime and other contaminants that could interfere with adhesion. Allow the surface to fully dry.
Sand Down Rough Areas
Use 100-grit sandpaper to smooth any bumps, residues of adhesive or other roughness on the wall surface that the backsplash will adhere to.
Ensure the Wall is Dry
Test the moisture level of the wall using a surface moisture meter in several spots. Only move forward if readings show the area is completely dry. Any lingering moisture will compromise the repair.
Fill Holes and Imperfections
Use spackling compound to fill any holes, cracks or uneven areas in the walls beneath the backsplash. Allow filler to dry completely and sand smooth.
Remove Outdated Backsplash
If you’ve decided to do a full replacement, carefully pry off and discard the existing failing backsplash. Scrape off all traces of old adhesive. Wipe down the exposed area before installing the new backsplash.
Repairing Peeling or Cracked Areas
For backsplashes with minimal damage, you may be able to repair peeling spots and cracks. Here are some tips:
Reactivate Adhesive
In loose spots where the backsplash can be pressed back into place, you may be able to reactivate the original adhesive. Use a heat gun to warm the area for 30-60 seconds. Quickly press the vinyl back into place, holding for 30-60 seconds while the adhesive cools and sets.
Apply New Adhesive
For loose areas that cannot be reactivated, apply a thin layer of liquid glue adhesive to the back of the vinyl. Press the piece firmly back into place, wiping away any excess adhesive that squeezes out. Weight down the area with a book or other heavy object for several hours as the adhesive dries.
Patch Small Holes
For small holes or tears, you can purchase peel and stick vinyl patches from a hardware store. Cut a patch slightly larger than the hole. Prepare the surface as described above. Peel off the patch’s adhesive backing and press it firmly over the damaged area.
Seal Cracks
Use a clear flexible caulk to seal any surface cracks or splits in the vinyl material itself. Carefully squeeze caulk into the crack and use a putty knife or damp finger to smooth it flat with the surface. Wipe away excess.
Replacing Sections of Backsplash
If you have large areas or full sections that are damaged beyond repair, replacement vinyl panels can be bought to patch in new pieces.
Purchase Replacement Panels
Take a sample of your backsplash to a home improvement store to find replacement panels that closely match the color, pattern and texture. Only replace sections, not the entire backsplash.
Cut Out the Damaged Section
Using a sharp utility knife, carefully cut out and remove the failing portion of the backsplash. Try to make straight cuts along grout lines, seams or edges for the best look. Discard the damaged section.
Dry Fit the New Panel
Cut the replacement panel to the approximate size needed. Dry fit it into the opening without adhesive to ensure you have a good fit along all edges before permanently attaching it.
Prepare the Surface
Clean, sand and dry the now-exposed wall section where the new panel will be installed. Apply painter’s tape along any edges where existing backsplash will remain. This prevents adhesive seepage.
Apply Adhesive
Spread a layer of liquid adhesive on the back of the new panel, keeping it 1/4″ away from edges. Carefully press into place in the opening, sliding it into position. Use a J-roller or heavy book to apply even pressure.
Clean Up Excess Adhesive
Allow the adhesive to cure following package directions. Use a plastic spackling knife to gently scrape away any adhesive that oozed out along seams or edges. Wipe area clean.
Fill Gaps as Needed
If there are slight gaps where the replacement panel meets existing backsplash, fill them in with a thin bead of clear silicone caulk. Use a fingertip or caulk shaping tool to smooth the caulk flush. Allow to fully dry before use.
Improving Adhesion of Whole Backsplash
In cases where the entire backsplash is intact but losing adhesion, you may be able to salvage it by re-securing it to the wall.
Lightly Roughen the Surface
Using 100-grit sandpaper, lightly sand the entire vinyl surface. This roughens it up for better mechanical adhesion. Avoid scuffing through the top vinyl layer. Wipe away sanding dust.
Apply Adhesion Promoter
Brush on a thin coat of adhesion promoter or primer made for plastic surfaces. Allow to dry completely. This further etches the surface profile for enhanced bonding.
Apply Construction Adhesive
Using a caulking gun, apply 1/4″ diameter beads of construction adhesive along the backsplash every 6 inches both vertically and horizontally. This creates a grid pattern across the whole backsplash.
Press Back into Place
Carefully press the entire backsplash firmly back onto the wall surface, sliding it into position. Use a J-roller across the entire surface to flatten adhesive beads and ensure even contact and pressure.
Clean Up Excess Adhesive
Allow adhesive to cure for 24-48 hours. Use a plastic spackling knife to gently scrape away any adhesive that squeezed out along edges or seams. Wipe surface clean.
Seal Perimeter with Caulk
Once cured, apply a thin bead of clear silicone caulk along the top and side perimeter edges of the backsplash. Use a caulking tool or fingertip to smooth the caulk and seal the backsplash edge to the wall.
New Backsplash Installation Tips
If your backsplash requires complete replacement, proper installation technique will give the new backsplash the best chance for longevity.
Select Moisture-Resistant Materials
When choosing new backsplash materials, look for vinyls, metals, glass or porcelain tile rated for kitchen use. Avoid unprotected paper or wood backsplashes near sinks or stoves.
Ensure Proper Wall Prep
Thoroughly clean and dry the wall surface. Fill any dents, holes or uneven areas. Apply painter’s tape along the edges. Prime very porous surfaces like new drywall.
Follow Adhesive Directions
Use the type of adhesive recommended by the backsplash manufacturer. Many require liquid glue applied to the backsplash itself, not the wall. Follow all application and curing directions.
Roll the Surface
After pressing the backsplash into place, roll the entire surface using a J-roller or grout float to flatten any air pockets and ensure maximum adhesive contact. Pay extra attention to corners.
Seal All Edges
Once adhesive has cured, apply a thin, continuous bead of silicone caulk along all top and side edges of the backsplash. Smooth the caulk with a finger or tool. This seals and protects perimeter edges.
Consider Backsplash Extenders
For easier installation and removal, some companies make vinyl backsplash extenders that mount on top of existing backsplashes to refresh the look without mess or damage to original backsplash.
Troubleshooting Common Problems
Even with proper installation and care, backsplashes can still fail. Here are some common issues and their solutions:
Problem: Backsplash develops crack lines or bubbles.

FAQs About Fixing Peel and Stick Backsplashes
Still have some questions about repairing and replacing failing peel and stick backsplashes? Here are answers to some frequently asked questions:
Is it possible to just re-stick a peeling backsplash?
It depends on the extent of the damage. For small areas that are just starting to peel, you may be able to reactivate the adhesive or apply new adhesive to re-stick it. But for backsplash with widespread bubbling, lifting or cracking, full replacement will be needed.
What’s the best adhesive to use when replacing sections?
Look for a flexible vinyl-specific glue formulated for backsplashes. Liquid adhesives typically provide the strongest bond. Avoid all-purpose glues which can fail prematurely.
Can I install the new backsplash right over the existing one?
No, you should always remove the entire failing backsplash first. Any texture or unevenness will prevent proper adhesion. The new backsplash must be applied directly to the wall surface.
How long does the adhesive need to dry?
Adhesive cure times vary by product but are usually 24-48 hours. Some may take up to 72 hours to fully set. Avoid any moisture contact until the adhesive has cured.
Why does my backsplash crack whenever I use the stove?
Excessive heat exposure can cause the vinyl to expand and contract, leading to cracks and bubbles. Try limiting heat sources directly under backsplash or replace it with a more heat-resistant material.
What’s the best way to cut peel and stick backsplash panels?
Use a very sharp utility knife and metal ruler to score and snap panels to size. Change blades frequently for clean cuts. You can also use a fine-toothed jigsaw. Make sure cuts are straight.
Can I apply new backsplash right over existing tile?
No, it should only be applied over flat painted wall surfaces. The texture of tile will prevent proper adhesion. You may be able to install backsplash extenders over existing tile.
How can I prevent mold or mildew on vinyl backsplash?
Improve kitchen ventilation and moisture control. Avoid direct splashing onto backsplash. Clean with bleach solution periodically. Re-caulk perimeter seals if needed. Choose mold-resistant materials.
Why does caulk peel off my backsplash edges so quickly?
Silicone or latex caulk can peel if it didn’t fully adhere to the vinyl surface. Always use 100% silicone, clean thoroughly first and allow proper drying time. Reapply caulk every 1-2 years.
Can I install a backsplash myself or do I need to hire a pro?
With some basic skills and tools, peel and stick installation is totally DIY-friendly. But for large format tile or glass backsplashes, professional installation is recommended.
