How to Install Stainless Steel Backsplash

Installing a stainless steel backsplash can completely transform the look of your kitchen or bathroom. A sleek, modern metal backsplash brings style and luxury to any space. While a stainless steel backsplash offers great benefits, installing it requires some careful planning and precision. With the right preparation and tools, you can achieve a flawless stainless steel backsplash installation. This comprehensive guide will walk you through the entire process step-by-step.

Choosing Your Stainless Steel Backsplash

The first step is selecting the perfect stainless steel backsplash material for your space. Here are some key factors to consider when making your selection:

Material Grade

Stainless steel backsplashes are available in different grades, with 304 and 316 being the most common. Grade 304 is the most affordable option but is more prone to corrosion over time, especially in coastal areas. 316 has more nickel content, making it more resistant to rust and corrosion. For kitchens and bathrooms with exposure to moisture, 316 is worth the extra cost for durability.


You can choose from polished, brushed, colored, or patterned finishes for your stainless steel backsplash. Polished stainless has a chrome-like mirror finish that gleams. Brushed stainless has a soft matte look with subtle graining. Colored stainless allows you to add a bold pop of color. Patterned or embossed stainless provides beautiful visual texture. Consider the overall look you want before deciding on a finish.


Stainless steel gauge refers to the thickness, with lower numbers indicating thicker steel. A thicker gauge will be more durable and resistant to dents. For a backsplash, 20, 18, or 16 gauge stainless steel is ideal. Thinner 22 or 24 gauge is prone to scratching and warping over time.


Stainless steel backsplash sheets typically come in 4×8, 4×10, or 4×12 foot sizes. Make sure to measure your backsplash space carefully to determine what size sheets you’ll need. Also factor in any seams or joints you’ll need between sheets.

Additional Protective Film

Stainless steel with a PVC film will resist fingerprints and scratches during installation. Peel off the film after completing the install. An acrylic coating also adds an extra layer of protection.

Gather the Right Tools and Materials

Installing stainless steel backsplash requires using specialized tools to get clean, precise results. Be sure to have these essential installation supplies on hand:

  • Tin snips – for cutting sheets to size
  • Level – for keeping sheets straight and even
  • Laser measure – for precision measurements
  • Carpenters square – for perfect 90 degree angles
  • Drill with metal bits – for clean perforations
  • Aviation snips – for smooth curved cuts
  • Rubber mallet – for gently adjusting sheets
  • Screwdriver or electric screwgun
  • Backsplash adhesive – look for a premium construction adhesive designed for metal
  • Stainless steel screws – self-tapping screws are ideal
  • Silicone caulk and caulk gun
  • Non-abrasive rags and cleaner – for polishing off fingerprints
  • Painter’s tape – for clean edges and masking
  • Safety gear – gloves, eye protection, knee pads

Make sure to use only stainless steel compatible adhesives, cleaners, and tools to prevent corrosion or damage. Low quality hardware store variety tools won’t provide the best results for your stainless backsplash. Investing in high quality specialty tools is well worth it.

Prepare the Surface

Take time to make sure your backsplash surface is ready for installation. Follow these steps:

  1. Clean the surface thoroughly – Remove any old backsplash material, debris, grease, or grime. Wash with an all-purpose cleaner and let dry fully.
  2. Smooth out imperfections – Fill any cracks, holes, or uneven spots with spackle. Sand smooth once dry.
  3. Prime the surface – After cleaning, apply a coat of metal primer. This helps the adhesive bind properly.
  4. Mark your design – Map out the backsplash layout with painter’s tape to visualize placement. Mark cutting lines with pencil.

Proper surface prep prevents problems like poor adhesion, rust, and staining later on.

Measure and Cut the Sheets

Precision cutting is crucial for a flawless finished look. Follow these best practices when measuring and cutting your stainless steel:

  • Use a laser measure or steel ruler for precision. Measure twice to confirm accuracy.
  • Cut sheets 1-2 inches larger than your space to allow room for adjustments.
  • Clamp sheets securely to a table when cutting to prevent vibrations.
  • Use tin snips for straight cuts and aviation snips for curves. Cut slowly and smoothly.
  • Wear heavy work gloves – stainless steel edges are extremely sharp!
  • Deburr all cut edges with a metal file to remove sharp burrs.

Take your time with measurements and cuts to avoid costly mistakes. Having an extra set of hands can be helpful for large stainless sheets.

Apply Adhesive and Mount Backsplash

With your sheets cut, it’s time to adhere the stainless steel backsplash to the wall. Follow this process:

  1. Apply adhesive in a zig-zag pattern over the entire back of the sheet, spreading evenly with a notched trowel.
  2. Remove backing paper from any factory-applied adhesive strips.
  3. Lift and align sheet into final position on wall. Press and smooth firmly.
  4. Use a level and carpenter square to ensure the sheet is plumb andstraight.
  5. Use clamps or screws with washers in top corners to secure in place while adhesive dries.
  6. Use a rubber mallet to gently tap sheets into proper alignment if needed.
  7. Clean up any adhesive squeeze-out right away with a putty knife and cleaner.

Applying even pressure produces the strongest adhesion and prevents bubbles or ripples in the metal. Allow adhesive to fully cure for 24-48 hours before moving on.

Finish Edges and Seams

Once the main sheets are adhered, you can complete outside edges and seams between sheets:

  • Carefully measure and cut border pieces to fit any exposed edges using snips. Deburr edges.
  • Apply adhesive to back of border pieces and firmly press into place on edges.
  • Use silicone caulk to fill any small gaps at seams or edges. Smooth with a finger or caulk tool.
  • For larger seams between sheets, use stainless steel trim molding secured with silicone adhesive.
  • Consider adding trim molding around the perimeter of the entire backsplash for a finished look.

Taking time to neatly finish all exposed edges gives your project a seamless, built-in look.

Secure and Seal

Adding mechanical fasteners and a protective sealant provides extra strength and durability:

  • Using a drill with stainless steel bits, drive screws with washers every 8-12 inches across entire backsplash surface.
  • Apply a bead of clear silicone caulk around all edges and seams. Smooth with a wet finger for a polished look.
  • Allow caulk to fully cure for 24-48 hours before exposing to moisture.
  • Use painter’s tape around the borders to keep caulk neat and prevent damage to surrounding surfaces.

Water exposure can loosen adhesive over time. Mechanical fasteners and sealant prevent moisture issues.

Clean and Maintain

Caring for your stainless steel backsplash properly preserves its gorgeous finish:

  • Always use non-abrasive cleaners designed for stainless steel. Avoid bleach, ammonia, or acidic cleaners.
  • For routine cleaning, wipe down with a microfiber cloth, mild dish soap and warm water.
  • Use a stainless steel polish/cleaner weekly to protect and enhance the luster.
  • Rinse thoroughly after cleaning and dry any splashes right away to prevent water spots.
  • Re-seal with silicone caulk annually or whenever needed to prevent moisture creeping in.

With proper care and maintenance, your stunning stainless steel backsplash will stay beautiful and corrosion-free for years to come.
