How to Install PS Wall Panels: A Step-by-Step Guide for Commercial & Residential Projects

Tools and Materials Required
- PS Wall Panels & Metal Trim
- Neutral Nail-Free Glue & Caulking Gun
- Tape Measure, Pencil & Level (Laser or Spirit)
- Utility Knife & Steel Ruler
- Pneumatic Nail Gun (Optional for heavy commercial sites)
Pre-Installation Checklist
- Substrate Check: Ensure the mounting wall (drywall, plywood, or concrete) is clean, dry, flat, and dust-free.
- Acclimatization: Store panels flat in the room for at least 24 hours before installation.
- Waste Margin: Order 5% to 8% extra material for cutting and trimming allowance.
Step-by-Step Installation Guide
Step 1: Measure the Size of the Wall
Measure wall height and width. Establish a straight reference baseline using a laser level.
Step 2: Stick Nail-Free Glue on the Back of the PS Wall Panel
Lay the panel face down on a soft surface. Apply continuous wavy/S-shaped beads of neutral nail-free adhesive along the back face.
Step 3: Paste the PS Wall Panel onto the Wall
Align the first panel with your baseline starting from a corner. Press firmly across the surface for several seconds to bond.
Step 4: Paste Other PS Wall Panels in Turn
Mount subsequent panels side-by-side, pushing them tightly together for seamless joints. Periodically check level alignment.
Step 5: Measure the Remaining Wall Space
Measure the exact width or height needed when reaching wall edges, corners, or obstacles. Transfer measurements to the back of a new panel.
Step 6: Use a Knife to Cut It on the Back of the PS Wall Panel
Lay the panel face down, align a steel ruler along the mark, and score firmly with a utility knife. Snap cleanly from the back to protect the front decorative finish.
Step 7: Install the Metal Trim
Insert decorative metal profiles along top or transition edges to cover cut lines and add a modern accent.
Step 8: Continue to Install Other Wall Panels
Repeat the process until the full wall area is covered.
