Step-by-Step Guide to Installing Stainless Steel Cladding for Commercial Kitchens

Installing stainless steel cladding in a commercial kitchen is one of the most effective ways to achieve a clean, hygienic, and durable wall surface. Stainless steel not only provides a modern, professional appearance but also ensures long-term resistance to heat, moisture, and bacteria. When installed correctly, it creates a seamless, low-maintenance surface that stands up to the daily demands of a busy catering environment.

This step-by-step guide explains how to prepare, install, and finish stainless steel wall cladding for commercial kitchens to ensure a professional, long-lasting result.

Step 1: Assess and Prepare the Wall Surface

Before beginning installation, the wall surface must be clean, dry, and structurally sound. Remove any grease, dust, paint, or loose material, and ensure the wall is smooth and even.

If there are cracks, holes, or uneven areas, fill them using a suitable wall filler and sand them flat. Stainless steel cladding performs best when bonded to a stable, flat substrate such as plasterboard, plywood, or cement board.

Check for moisture or damp issues before proceeding. Installing over a damp surface can cause adhesive failure and corrosion over time.

Step 2: Measure and Plan the Layout

Accurate measurement is essential for a seamless installation. Measure the wall dimensions carefully and plan the layout of the stainless steel sheets.

It’s best to start from a corner or a central focal point and work outwards, ensuring joints fall evenly across the wall. Mark out any areas that will need cut-outs, such as electrical sockets, switches, or pipe openings.

Allow for a small expansion gap—typically around 2–3mm—between panels and fixed edges to accommodate thermal movement.

Step 3: Cut the Stainless Steel Sheets

Cutting stainless steel requires precision and the right tools. For thin sheets (usually 0.9mm to 1.2mm thick for wall cladding), use tin snips, a jigsaw with a fine metal blade, or an angle grinder with a stainless steel cutting disc.

Always wear protective gloves and safety glasses when cutting. To prevent scratching the visible surface, keep the protective film on the panels until installation is complete.

Once the sheets are cut to size, de-burr the edges with a fine file to remove sharp edges and ensure a clean fit.

Step 4: Apply Adhesive or Mechanical Fixings

There are two main installation methods for stainless steel cladding: adhesive bonding and mechanical fixing.

Adhesive Fixing: Apply a high-strength, solvent-free construction adhesive or a specialist stainless steel cladding adhesive in vertical lines or dots across the rear of the panel. The adhesive pattern should ensure full contact without trapping air pockets.

Mechanical Fixing: For environments subject to high heat or moisture (e.g. behind cooklines), consider using stainless steel screws, rivets, or channels. This allows for easy removal and re-installation if needed.

In most commercial kitchens, a hybrid approach—adhesive bonding with discreet screw fixings at the edges—offers the best combination of security and aesthetics.

Step 5: Position and Secure the Panels

Once adhesive or fixings are ready, position the first stainless steel sheet carefully against the wall, ensuring it is level and aligned. Press firmly from the centre outwards to distribute the adhesive evenly and remove trapped air.

If using screws, place them along the top and bottom edges and cover with stainless steel trim profiles for a neat finish. Use a rubber mallet and straight edge to ensure each sheet sits flush against the wall.

Continue installing additional panels, checking alignment regularly to maintain a seamless look. Ensure that joints are tight and expansion gaps are maintained.

Step 6: Seal the Joints and Edges

Proper sealing is essential to maintain hygiene and prevent water ingress. Use food-safe, heat-resistant silicone sealant along all vertical and horizontal joints. This creates a watertight barrier that stops dirt, grease, and bacteria from collecting between panels.

Install stainless steel corner trims, edge trims, and capping profiles to complete the look. These not only enhance appearance but also protect vulnerable edges from impact and wear.

Step 7: Final Cleaning and Inspection

Once the cladding is securely in place and sealant has cured, remove the protective film from each panel. Clean the surface using a soft cloth and a non-abrasive stainless steel cleaner to remove fingerprints and residue.

Inspect all joints, edges, and trims for consistency and ensure there are no gaps or loose sections. The result should be a smooth, reflective, hygienic surface that’s easy to wipe down and maintain.

Maintenance Tips

Stainless steel cladding is incredibly durable, but regular cleaning will keep it looking its best. Use warm water, mild detergent, or specialist stainless steel cleaner—never harsh chemicals or abrasive pads. Wipe in the direction of the grain for a streak-free finish.

Conclusion

Installing stainless steel cladding in a commercial kitchen provides more than just a clean, professional appearance—it delivers long-term hygiene, durability, and fire resistance. By following the correct preparation and installation steps, you can ensure the cladding performs flawlessly for years to come.

Whether you’re refurbishing a restaurant kitchen or designing a new catering facility, stainless steel wall cladding is a smart investment that meets the highest hygiene and safety standards while enhancing the overall look of your workspace.
