Removing a backsplash can often lead to damage to the underlying drywall. Fixing this damage is important for both aesthetic and practical reasons. Repairing drywall after backsplash removal may seem daunting, but it can be accomplished with some simple tools, materials, and techniques.
Assessing the Damage
The first step is to thoroughly examine the area where the backsplash was removed. Look for:
- Cracks or holes in the drywall’s paper surface
- Damage, dents, or gouges in the gypsum core
- Areas where the drywall is still attached to the backsplash adhesive
Also check the surrounding drywall for any collateral damage that may have occurred during backsplash removal.
Pay particular attention to areas around electrical outlets or plumbing fixtures. Removing backsplashes improperly can sometimes cause damage to the drywall behind or around these items.
What Tools Will You Need?
Before starting any drywall repairs, assemble the necessary tools:
- Utility knife – for scoring and cutting drywall
- Drywall saw – for cutting openings or holes
- Taping knives – for applying joint compound
- Sanding block and sandpaper – for smoothing repairs
- Drywall screws and screwdriver – for reattaching loose drywall
- Electric drill and drill bits – for screw holes
- Dust mask – for protection from drywall dust
- Safety goggles – for eye protection
You may also need a stepladder, depending on the height and location of the damaged drywall.
Purchase Patching and Finishing Materials
Typically the following materials are needed for drywall repairs:
- Drywall pieces or drywall repair patches
- Joint tape – for covering seams
- Joint compound (also called mud) – for coating seams and patches
- Drywall primer and paint – for refinishing repairs
The amount and type needed will depend on the extent of damage. Inspect closely to determine if entire sheets, custom cut pieces, or just simple patches will be required.
Remove any Remaining Backsplash Adhesive
Before patching damaged spots, you must ensure the underlying drywall is clean and free of old adhesive.
Check for any residual thinset mortar, mastic, double-sided tape, or other substances used to attach the backsplash. Use the following steps to eliminate any remaining adhesive:
- Scrape off any chunks and loose material with a putty knife or chisel.
- For thinset mortar, carefully scrape and chip away with a hammer and chisel. Go slowly to avoid damaging the drywall.
- Use a utility knife to score through any remaining mastic or sticky tape residue.
- After scoring, spray warm water mixed with dish soap and scrub with a stiff bristle brush. The soap allows the water to saturate the adhesive.
- Wipe the surface clean using clean water and rags. Scrub with an abrasive pad for stubborn deposits.
- Sand any remaining adhesive nubs or uneven texture using 100-150 grit sandpaper.
Repeat this process until all remnants of the backsplash adhesive are gone and the drywall is smooth, clean, and ready for patching.
Prepare the Damaged Drywall Surface
Now that the backsplash adhesive is removed, you can start preparing the drywall itself for repairs:
1. Cut or Tear Out Any Loose Paper or Damaged Areas
Use a utility knife to carefully cut or score damaged or detached drywall paper. Remove any separated paper or unrepairable drywall.
If the gypsum core is gouged, cratered, or uneven, tear out the damaged section. Make square-cut openings with clean edges.
2. Vacuum the Repair Area Thoroughly
Use a crevice tool and brush attachment to remove gypsum dust, shards, and debris from the repair area. Vacuum surrounding surfaces too.
3. Wipe Down with a Damp Cloth
Wipe the damaged drywall area with a damp cloth to eliminate dust. This helps patches and joint compound adhere properly. Allow to fully dry before patching.
Cut Patch Pieces to Fit Damaged Areas
Once the surface is prepped, you can cut replacement pieces of drywall:
- For holes or small areas, use precut drywall repair patches. Press into place to mark sizing.
- For larger areas, measure and mark piece size needed. Cut replacement pieces to fit using a drywall saw.
- Cut patch edges square and straight for proper adhesion and smoothing.
- Double check fit before attaching patch pieces. They should fit snugly without gaps or overlaps.
Use 1/2″ drywall for patch thickness matching surrounding areas. Cut pieces slightly larger to allow for joint compound buildup when finishing.
Secure Patches and Replacement Pieces
Next, secure any replacement drywall pieces using drywall screws. Take care not to overdrive screw heads as this can damage the paper surface. The steps include:
- Pre-drill holes if needed to prevent tearing drywall paper.
- Position patches over openings and secure with drywall screws, 8-12 inches apart along seams.
- On tears or seams with detached paper, reattach the paper using drywall screws.
- Drive screws down just below surface without punching through paper.
- For small patches, you can also use construction adhesive instead of screws.
Patch edges should fit snugly. Do not overlap seams. Any gaps between patches will need to be covered with joint tape.
Apply Joint Tape Over All Seams and Joints
Once patches are secure, cover all seams between pieces with joint tape:
- Use fiberglass mesh tape for most drywall repairs. It embeds easily into joint compound.
- For large repairs, paper joint tape is more durable and prevention cracking.
- Cut tapes to length using utility knife. They should cover seams with 1-2 inches excess on each side.
- Embed tape into a thin layer of joint compound using a taping knife.
- Smooth the joint compound over the tape, filling any gaps or edges.
- Use finesse to avoid ripping or distorting the tape. Let compound dry completely.
The joint tape provides strength and stability as it bonds patches together when the joint compound dries.
Apply Joint Compound Over Patches and Tape
With patches secured and seams taped, you can start building up layers of joint compound to blend repairs:
- Apply a thin coat of compound over all patches using a drywall knife. Feather out edges.
- Let the first coat dry fully, then sand lightly to smooth.
- Apply a second coat, extending it slightly beyond the first coat.
- Build up thin layers over several applications vs. one thick coat.
- Sand between coats for best smoothing.
Take care not to gouge the paper when sanding. Wipe away dust between applications.
Skim Coat Entire Repair Area
For the final application, skim coat the entire sanded repair area:
- Spread a thin final layer to cover patches, seams, and surrounding drywall.
- Feather out edges so they blend seamlessly into wall surface.
- Use a 14-16” knife for the final skim coat to properly feather edges.
- Let dry fully, then sand entire surface to smooth.
The skim coat helps hide imperfections and blend the patchwork into the wall surface.
Prime Repaired Areas and Finish Painting
Once joint compound is completely dry:
- Lightly sand any remaining ridges or imperfections.
- Remove dust and wipe repair area with damp cloth.
- Apply drywall primer allowing complete drying.
- Finish paint repair areas using roller and brush. Feather out edges.
- Apply a second finish coat of paint if needed to match surrounding color.
Be sure to use adequate ventilation when sanding and painting.
Tips for Professional looking Repairs
Follow these tips and techniques for repairs that blend in seamlessly:
- Take time to prep surfaces thoroughly – this leads to better adhesion.
- Apply multiple thin coats of joint compound vs. one thick one.
- Use wider drywall knives for smoother, flatter applications.
- Let joint compound dry fully between coats.
- Be meticulous when sanding between coats.
- Carefully feather out edges of patches and skim coat.
- Use high quality drywall primer that seals surface.
- Apply finish paint generously to fully cover repairs.
With careful surface preparation, patience, and some practice, even major drywall damage can be repaired to look seamless.
