Removing a backsplash can often damage the wall behind it. Holes, chips, peeled paint, and residue are common issues that need repairing before installing a new backsplash. Properly repairing the wall takes time and care but ensures your new backsplash looks flawless. Follow these steps to repair walls after removing a backsplash.
Assess the Wall Damage
Carefully examine the entire wall surface after removing the old backsplash. Look for any cracks, holes, missing chunks of drywall, peeling paint or wallpaper, and adhesive residue. Make note of all problem areas and identify the repairs needed.
Common types of damage include:
- Holes or gouges – Backsplash tiles are often set into the wall with mortar. Removing the tiles can pull off chunks of drywall or plaster. Holes may also be caused by pulling out old wall anchors or screws.
- Cracked or peeling drywall tape – Drywall seams covered with mesh tape can crack when tiles are removed. Moisture from mortar can also degrade taped joints.
- Peeling paint or wallpaper – Mortar, adhesive, and tile removal can strip off layers of paint and wallpaper. This exposes uneven surfaces underneath.
- Adhesive residue – Old mastic or mortar used to attach the backsplash leaves behind sticky residue. This must be fully removed before repainting.
Thoroughly inspect behind and around electrical outlets or plumbing fixtures too. Damage often occurs in these areas when removing tiles.
Clean the Entire Surface
Clean the wall thoroughly after removing the old backsplash. This prepares the surface for repairs and new paint or wallpaper.
Follow these steps:
- Wipe away any dirt, dust, grease, or grime with a sponge and warm water. Rinse well.
- Mix up a solution of trisodium phosphate (TSP) and water. Scrub all surfaces to cut through grease and remove leftover tile mastic.
- Use a putty knife to scrape off any remaining mortar, mastic, or adhesive residue. Go gently to avoid gouging the wall.
- Sand any bumps or uneven areas with 100-grit sandpaper. Be careful around drywall seams.
- Vacuum up all dust and debris when finished cleaning.
Proper cleaning removes contaminants that could prevent paint or wallpaper from adhering correctly. It also provides the bare surface needed for repairs.
Repair Holes and Damage
Fill any holes, gouges, cracked joints, or missing drywall pieces with patching compound. Here’s how:
- Use a putty knife to fill small holes with lightweight spackling paste. Apply several thin layers, allowing each to dry before adding more.
- When dry, sand the area smooth and even with the wall.
- Cut a piece of drywall to fit each hole. Secure in place with drywall screws driven into the wall studs.
- Cover seams between patches and existing drywall with self-adhesive fiberglass mesh tape.
- Apply a thin layer of drywall joint compound over the tape with a putty knife. Smooth to blend with the wall. Allow to dry.
- Apply a second coat of joint compound, feathering the edges to hide seams. Sand when dry.
- Finish with a third layer of compound if needed to achieve a smooth surface. Prime and paint when fully dry.
Damaged Drywall Seams
- Remove any loose drywall tape and scrape away old compound.
- If the seam shows a gap, inject expandable foam filler into the gap to support the edges.
- Apply new self-stick fiberglass mesh tape over the seam.
- Cover with 1-2 coats of drywall joint compound, feathering out edges. Sand smooth when dry.
Be sure repairs are smooth and level with the surrounding wall area. Uneven patches will show through the new backsplash.
Skim Coat Walls
Applying a thin skim coat of joint compound helps level uneven walls. This provides a smooth, uniform surface for the new backsplash.
Follow these tips:
- Thoroughly clean and dry the wall first.
- Use a smooth trowel to apply a tight 1/16” layer of drywall joint compound across the entire surface. Work in 4×4 foot sections.
- Immediately use a drywall knife to scrape and smooth the wet compound. Feather out the edges.
- Allow the skim coat to fully dry before sanding or applying a second coat if needed.
- Lightly sand any ridges or tool marks to achieve a flat surface.
Avoid applying the compound too thickly. Take your time to spread it evenly in thin, smooth layers.
Prime Repaired Walls
Once all repairs are complete, apply a coat of primer designed for wallboard and plaster. Primer seals porous surfaces and provides added durability beneath the new paint or wallpaper.
Choose an appropriate primer:
- For painted walls, use a high-quality acrylic primer/sealer. This works on repaired drywall and plaster.
- For new or bare drywall, use a drywall primer. Look for one that resists mold and mildew.
- For newly skim coated walls, use a PVA or drywall primer specifically made for skim coating projects.
Follow the manufacturer’s directions to apply the primer. Be sure to use adequate ventilation – many types contain strong fumes.
Priming provides an even finish for the new backsplash. On freshly repaired or skim coated walls, it helps stop joints and patches from showing through the paint.
Apply New Paint or Wallpaper
Once primed, the repaired wall can be painted, or covered with new wallpaper depending on your plans.
- Choose a top-quality latex paint designed for kitchen walls and backsplashes. Look for mold/mildew resistance.
- Opt for satin, eggshell, or semi-gloss sheens. Avoid flat paint behind a backsplash.
- Carefully apply 2-3 finish coats of paint, allowing proper dry time between coats.
- Select wallpaper approved for kitchen installation. Washable vinyl or acrylic-coated papers work best.
- Carefully follow adhesive application directions. Use a plastic smoother to remove any bubbles or wrinkles.
- Treat seams according to the manufacturer’s instructions to prevent moisture damage behind the backsplash.
Take your time applying the new wall finish. Careful prep and repairs ensure it adheres smoothly and lasts.
Install the New Backsplash
Once the wall repairs are complete and the new paint or wallpaper applied, you are ready to install the new backsplash.
Be sure to:
- Allow the wall finish to cure fully before setting tile. Check paint or wallpaper directions.
- Use a premium quality tile mortar suitable for kitchen backsplash use.
- Follow all manufacturer’s instructions for surface prep and tile application.
- Grout and seal the backsplash once set according to directions.
With the wall in fresh, flawless condition, the new backsplash tiles or panels can be installed for a revitalized kitchen look.
Common Backsplash Wall Damages and Repairs
Removing a kitchen backsplash often leaves the wall underneath in less than perfect shape. Holes, adhesive residue, and other damage must be properly repaired before installing a new backsplash. Here are some of the most common backsplash removal damages and how to fix them.
Holes and Missing Drywall
Backsplash tiles set into the wall can pull out chunks of drywall or plaster when removed. Screws or anchors used to attach the old backsplash can also leave unwanted holes.
- Small holes can be filled with lightweight spackling compound, applied in thin layers.
- For large holes or missing drywall pieces, cut a patch to fit and secure in place with drywall screws into the studs.
- Cover seams between patches and wall with self-stick fiberglass mesh tape and drywall joint compound. Feather out edges.
Be sure patches are smooth and blend seamlessly with the surrounding wall.
Cracked Drywall Seams
Kitchen walls can shift over time, causing drywall tape joints to crack or loosen. Mortar used to set tiles can also degrade taped seams.
- Carefully scrape off loose tape and any old joint compound.
- Fill any gaps in the seam with expandable foam backer rod.
- Apply new fiberglass mesh tape and feather out 1-2 coats of joint compound to hide cracks.
This restores strength to weakened seams before adding the new backsplash.
Torn Wallpaper or Peeling Paint
Removing backsplash tiles can strip off existing wallpaper or paint layers. Moisture from mortar may also bubble these wall finishes.
- Strip off all loose wallpaper or paint down to the bare wall surface.
- Remove any remaining adhesive residue with warm, soapy water. Rinse thoroughly.
- Patch any exposed wall holes or imperfections with joint compound. Sand smooth when dry.
- Seal repairs with a wallboard primer before applying new wallpaper or paint.
This provides a fresh, stable surface for the new wall finish.
Old mastic, mortar, or adhesive can leave behind a stubborn sticky residue on walls after the backsplash is removed.
- Try scrubbing the area with warm, soapy water first. Check wallpaper or paint for damage from moisture.
