In this comprehensive, expert guide, I‘ll walk you step-by-step through the entire process. From safe backsplash removal methods to evaluating and fixing any drywall damage, to prepping your wall for a stunning new backsplash. Follow these tips and you can refresh your space with minimal time, cost and frustration!

Can Backsplash Removal Damage Drywall?

Taking off a backsplash without inflicting at least some harm to the underlying drywall is a challenge. However, as a contractor whose renovated hundreds of bathrooms and kitchens over the past decade, I can tell you the severity of the damage can vary greatly depending on:

• Backsplash material – In my experience, tile backsplashes generally adhere more tightly than glass backsplashes. Thinner tile or mosaic sheets often bond extremely firmly to the wall surface.
• Quality of original installation – Backsplashes installed on top of a layer of adhesive or mortar, as recommended by the National Tile Contractors Association, typically grip more tenaciously to drywall than those adhered directly.
• Method and care taken during removal – Rushing through backsplash removal and using excessive prying force significantly increases chances of ripping off chunks of drywall.

While it‘s difficult to fully prevent damage, going slowly and using the proper tools can minimize it. Even if some imperfections in the wall surface occur, you can likely fix them without needing to replace entire sheets of drywall.

Step-by-Step: Safely Removing Backsplash to Avoid Drywall Damage

Follow these detailed steps to safely remove your existing backsplash while limiting damage to the underlying drywall:

Gather the Right Tools and Materials

You‘ll need:

• Flat pry bar – A sturdy metal one works best to provide enough leverage.
• Utility knife – For scoring through any grout or caulk.
• Grout saw or oscillating multi-tool – Cuts through grout quickly and cleanly.
• Putty knives – To scrape off adhesive and mortar. Get a few different sizes.
• Scraper – Choose a rigid one to prevent digging into drywall.
• Eye protection, work gloves, N95 mask – For safety.
• Drop cloths – To protect floors and surfaces from debris.
• Vacuum – To conveniently contain all dust and fragments generated.

Prep the Workspace

First, clear counters and protect flooring with drop cloths in your kitchen or bathroom. Also have a vacuum ready and easily accessible to contain dust and debris.

Cut Through Any Caulk or Paint Sealing Edges

If existing caulk or paint is helping adhere and seal the outer edges of the backsplash, take a utility knife and score through it completely before attempting tile removal. This breaks the outer seal.

Remove Grout Between Tiles

Use a dedicated grout saw or oscillating multi-tool (set to a low speed) to cut any remaining grout lines between the individual backsplash tiles. Removing the grout first helps break the tile free.

Slowly Pry Tiles Off Wall

With your backsplash grout lines cut, begin prying off the tiles. Carefully insert the flat pry bar behind each tile, gently levering it upwards. Continue along until all tiles are freed. Take your time and don‘t force anything too hard.

Thoroughly Scrape Off Leftover Adhesive

Once tiles are removed, use a putty knife to gently scrape any chunks or beds of remaining mortar, mastic or other adhesive from the now exposed wall surface. Try to remove adhesive without gouging the drywall paper facing.

Clean and Dry the Entire Wall Surface

Use a non-abrasive sponge or soft cloth with warm water to remove all adhesive residue from the former backsplash area. Let the whole wall completely dry before repairing any imperfections or flaws.

Should I Hire a Pro? DIY vs Professional Backsplash Removal

DIY backsplash removal is certainly possible for many handy homeowners but there are benefits to hiring a professional:

Pros of DIY Removal:

• More affordable – Saves on labor costs.
• Convenient scheduling – Remove on your own timing.
• Satisfaction of completing yourself – Gratification doing your own renovation work.

Pros of Hiring a Tile Contractor:

• Experienced with best practices – Removes with minimal drywall damage.
• Proper tools – Uses commercial grade removal tools.
• Repair drywall damage – Prepares flawless wall for new backsplash.
• Allows focusing on other tasks – Delegates work while you do more valuable activities.

According to HomeAdvisor, the average cost to hire a contractor for kitchen backsplash removal ranges from $200 – $850 depending on project scope. This is often money well spent to have expert work completed quickly and avoid making novice mistakes. For extensive backsplash projects, working with tile installation professionals may be your best option, especially if you don‘t have time or skills for potential drywall repairs.

Inspecting the Drywall After Backsplash Removal

Once your backsplash demo is complete, thoroughly inspect the now exposed drywall underneath. Check for:

• Holes or gouges – Can range from minor hairline cracks to large jagged chunks torn completely out.
• Uneven areas – Sections of wall that now appear wavy or warped due to adhesive pull.
• Water damage – Bubbling, sagging or staining that may have been hidden previously.
• Loose joint tape or compound – Any seams could now be compromised or exposed after surrounding tiles removed.

Also carefully examine the upper edges of the former backsplash area itself for any existing flaws extending above where it was mounted. Even very minor imperfections can become exaggerated eyesores once the new backsplash is installed.

You should also test for any latent moisture issues. Do this by taping a 1 foot square piece of plastic over a section of wall. If condensation develops on the inside of the plastic, your underlying drywall likely has concerning moisture penetration needing remedy before installing new backsplash.

Repairing Common Drywall Damage from Backsplash Removal

Here are solutions to repair the typical drywall flaws that can occur after removing backsplash tiles:

For small holes, dents and gouges:

• Use drywall joint compound and a putty knife to neatly fill any holes and dents. Allow compound to completely dry and cure.
• Once dry, lightly sand until smooth and even with surrounding wall surface.

For uneven lumpy or wavy areas:

• Sand down any protruding drywall high spots using 100-150 grit sandpaper until level with rest of wall.
• Fill any low spots with drywall joint compound and smooth carefully with a putty knife. Allow to fully dry.
• Once dry, sand affected areas again as needed ensure perfectly even surface.

For cracks around joint tape and seams:

• Apply new joint tape over any cracks or gaps, embedding it into a thin layer of joint compound.
• Feather out the compound several inches beyond the seam edges. Allow to completely dry.
• Once dry, lightly sand and then prime repaired seams before painting or tiling.

For water damaged drywall areas:

• Seal water affected areas with a quality shellac-based primer to block moisture.
• Cut out and replace any severely swollen, crumbling or moldy sections.
• Use blowers and dehumidifiers to thoroughly dry wall before applying new backsplash.

In some instances it may be simpler to just replace entire damaged drywall sheets rather than try to extensively repair them. This route also guarantees you start with an ideal blank-slate surface.

Prepping Your Wall for New Backsplash Installation

Once drywall repairs are complete, you need to properly prep the surface for optimal backsplash adhesion and longevity.

• Fill any remaining small dents or holes with joint compound. Allow to completely cure and then sand smooth.
• Skim coat the entire surface with a thin layer of drywall joint compound to smooth any lingering minor imperfections. Let dry fully.
• Thoroughly sand the entire backsplash area with 150 grit sandpaper until uniformly smooth and dust-free.
• Prime wall with quality enamel undercoater to create a unified surface for tile application.
• Install cement backerboard, fiber cement board or polymer-modified backerboard.

Take your time with each step and don‘t rush the prep work. Properly prepped drywall leads to a beautiful new backsplash installation.

What If the Drywall Damage is Too Severe?

If your drywall suffered serious gouging, mold or extensive water damage, replacement of damaged sections may be required for proper repairs. Here are a couple options if the flaws are beyond basic patching and priming:

Replace just the damaged portions

• Cut out the damaged drywall areas only, leaving surrounding undamaged areas intact.
• Purchase new drywall pieces to install in the cut-out spaces. Match thickness of existing drywall.
• Tape seams between new and old drywall, mud and sand until smooth. Prime before applying new backsplash.

Install a new wall surface material

• Consider water-resistant options like shiplap planks, plastic beadboard panels or metal backsplash tiles.
• Often, these new materials can attach directly over flawed drywall for easier install.
• Adds a stylish new look while providing practical benefits like moisture resistance.

Replacing only severely compromised areas retains unaffected drywall while providing an intact surface for backsplash tiles. New wall materials also eliminate any underlying flaws or moisture issues for reliable performance.

Protecting Walls During New Backsplash Installation

Be sure to exercise care when mounting and grouting new backsplash tiles to avoid damaging freshly prepped and repaired drywall:

• Use plastic spacers between tiles and wall surface while setting and adhere backsplash per manufacturer instructions.
• Don‘t force tiles if they won‘t stick – the wall surface likely needs more prep work.
• Apply grout release compound before grouting to minimize grout sticking to or staining surrounding drywall.
• Carefully sponge off any excess grout or tile adhesive that gets on wall area.

Conclusion

Eliminating an outdated or damaged backsplash doesn‘t necessarily require completely replacing your existing drywall. With careful removal, repair and thorough surface prep work, you can achieve gorgeous new tile or glass backsplash results while retaining your walls. Just be sure to fully address any underlying moisture issues or flaws for a long-lasting and worry-free installation.
