Replacing drywall for your kitchen backsplash can completely transform the look and feel of your kitchen. With some careful planning and the right tools, this is a DIY project that most homeowners can tackle successfully. This comprehensive guide will walk you through all the steps needed for replacing drywall behind a kitchen backsplash.
Selecting the Right Drywall for Your Backsplash
When choosing drywall for your backsplash project, you’ll need to consider factors like water resistance, mold resistance, and fire codes. Here are some of the best options:
Moisture-Resistant Drywall – Made with a water-repellent paper facing. Helps prevent water damage behind a backsplash but is not waterproof. Usually green in color.
Mold-Resistant Drywall – Treated to deter mold growth. Ideal for high-moisture areas like behind a sink or stove. Look for products that say “mold resistant” on the label.
Cement Board – Made from cement and cellulose fibers. Extremely durable and moisture-resistant but harder to cut and install. Often used for tile backsplashes.
Firecode Drywall – Special type of drywall needed if you live in a municipality that requires fire-rated walls behind stoves. Check your local building codes.
For most standard backsplash projects, moisture-resistant drywall offers the best blend of water protection and ease of installation.
Removing the Existing Backsplash and Drywall
Before installing your new backsplash, you’ll need to remove the old one along with any drywall behind it.
- Turn off electricity and gas to stove/outlets before starting demolition.
- Wear safety goggles, dust mask, and gloves.
Steps for Removal:
- Take out existing backsplash – Remove any silicone caulk at edges with a utility knife. Carefully detach backsplash tiles or panels using a pry bar.
- Take down old drywall – Use a drywall saw or utility knife to cut and remove drywall behind the backsplash area. Try to remove it in whole sheets if possible.
- Clean surfaces – Use a shop vacuum to remove dust and debris. Wipe surfaces with a damp cloth.
- Inspect plumbing and electrical – Replace any damaged wires or plumbing lines. Consult an electrician or plumber if needed.
- Prepare for new drywall – Studs should be 16 inches on center for proper drywall installation. Add furring strips if needed.
Measuring and Cutting New Drywall Panels
Now it’s time to measure and cut pieces of new drywall to perfectly fit your backsplash area.
Tips for Measuring:
- Use a stud finder to mark stud locations on the wall. You’ll need to secure edges of drywall to studs.
- Measure width and height of the backsplash area. Transfer measurements to drywall sheet.
- For outlets, measure opening size and locations on wall. Transfer to drywall.
- Use a utility knife with fresh blade to score the paper facing. Snap along score line to cut drywall.
- A circular saw with drywall blade also works for long cuts. Cut on the paper side of drywall, not the whitish gypsum side.
- Make small notch cuts at corners to allow drywall pieces to fit together.
- Wear goggles and dust mask when cutting drywall to avoid inhaling dust.
Installing the New Drywall Pieces
Now it’s time to fasten the drywall pieces you’ve cut to size onto the wall. Follow these tips for proper installation:
- Apply drywall adhesive to studs using caulking gun where the edges of each piece will attach.
- Lift drywall piece into place and press firmly against adhesive to adhere it.
- Drill drywall screws every 8-12 inches along stud lines and the top/bottom plates to firmly secure each piece.
- For outlet cutouts, secure drywall tightly against box using long drywall screws.
- Use joint compound and tape over seams between pieces. Apply thin coats and sand smooth when dry.
- Avoid placing seams where backsplash tiles will go. Offset seams from tile layout.
- Take time to ensure drywall is secure and seam edges are smooth before applying backsplash.

Mirrors: Light-reflecting and visually expanding. Use tempered glass panels cut to size. glue directly to drywall.
Peel-and-Stick: Budget option that uses adhesive backing already attached to tiles or panels. Easy DIY installation.
Preparing the Surface for New Backsplash

- Make sure drywall is smooth, dry, and dust-free. Sand any uneven areas.
- Clean thoroughly with an all-purpose cleaner and rinse with clear water.
- For tile, paint on a tile setting adhesive primer using rollers or brush. Allow to fully dry.
- If using backsplash panels, apply silicone adhesive caulk to the backside and let cure overnight face down.

- Apply silicone caulk between top edges of backsplash and countertop.
- Ensure backside has adhesive sheeting, silicone caulk, or construction adhesive attached.
- Dry fit pieces to ensure proper fit before peeling off adhesive backing.
- Press panels firmly to wall, holding 30 seconds. Use roller to adhere fully.
- For seams between panels, apply painter’s tape on wall 1/16 inch from edge to prevent gaps.
- Install filler panels at edges and corners after large panels are installed.
- Seal top edges with color-matched silicone caulk.
Caulking and Sealing the Backsplash
Once your backsplash is fully installed, finishing touches like caulking and sealing will help complete the project:

- For natural stone tile, apply quality sealant to help resist staining and damage from moisture.
- Wipe away any haze or excess caulk with damp sponge. Follow caulk manufacturer curing timeline before exposure.
- Do not apply grout sealant too soon or moisture can become trapped behind new tiles.
